Abstract
A system, device and method for enforcing privacy during a communication session with a voice assistant are disclosed. A user is authenticated via one or more first criteria in response to a request to initiate a communication session with a voice assistant. Sensor data is periodically acquired during the communication session and is processed to determine a number of persons present in an environment of the voice assistant via one or more second criteria. The communication of private data by the voice assistant is enabled when one person is in the environment and that person is the authenticated user, or when more than one person is present and the environment is determined to match the one or more predetermined privacy criteria for a multi-person environment. The communication of private data by the voice assistant is disabled when the one person in the environment is not the authenticated user.

Description of Example Embodiments
[0012] The present disclosure is made with reference to the accompanying drawings, in which embodiments are shown. However, many different embodiments may be used, and thus the description should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. Like numbers refer to like elements throughout, and prime notation is used to indicate similar elements, operations or steps in alternative embodiments. Separate boxes or illustrated separation of functional elements of illustrated systems and devices does not necessarily require physical separation of such functions, as communication between such elements may occur by way of messaging, function calls, shared memory space, and so on, without any such physical separation. As such, functions need not be implemented in physically or logically separated platforms, although they are illustrated separately for ease of explanation herein. Different devices may have different designs, such that although some devices implement some functions in fixed function hardware, other devices may implement such functions in a programmable processor with code obtained from a machine readable medium. Lastly, elements referred to in the singular may be plural and vice versa, except where indicated otherwise either explicitly or inherently by context.
[0013] In accordance with one embodiment of the present disclosure, there is provided a voice assistant device.

A privacy module is stored in the memory, the privacy module comprising executable instructions that, when executed by the processor, cause the voice assistant device to authenticate a user via one or more first criteria in response to a request to initiate a communication session with a voice assistant, and initiate the communication session with the voice assistant in response to a successful authentication of the user. The privacy module also causes the voice assistant device to, periodically during the communication session with the voice assistant, acquire sensor data from one or more sensors of the plurality of sensors, and process the sensor data to determine a number of persons present in an environment of the voice assistant device via one or more second criteria.
[0014] When one person is present in the environment of the voice assistant device, the sensor data is processed to identify the one person, and determine whether the one person is the authenticated user based on whether the one person is identified as the authenticated user. When the one person in the environment is determined to be the authenticated user, the communication of private data by the voice assistant is enabled. When the one person in the environment is determined not to be the authenticated user, the communication of private data by the voice assistant is disabled.
[0015] When more than one person is present in the environment of the .. voice assistant device, the sensor data is processed to determine whether the environment of the voice assistant device matches one or more predetermined privacy criteria for a multi-person environment. The one or more predetermined privacy criteria for the multi-person environment may involve assessing whether the multi-person environment is "private". The term "private" in the context of a multi-person environment may be that only authorized persons are present, that unauthorized persons are more than a threshold distance away, or that any persons other than the authorized users are more than a threshold distance away, as described more fully below.
[0016] When the environment of the voice assistant device is determined to match the one or more predetermined privacy criteria for a multi-person environment, communication of private data by the voice assistant is enabled.

Methods of enforcing privacy during a communication session with a voice assistant
Methods of enforcing privacy during a communication session with a voice assistant
[0060] Referring next to FIG. 3, a method 500 of enforcing privacy during a communication session with a voice assistant in accordance with one example embodiment of the present disclosure will be described. The method 500 is performed by a voice assistant device 200 which, as noted above, may be a multipurpose communication device, such as a smartphone or tablet running a VA
application, or a dedicated device, such as an IoT device (e.g., smart speaker or similar smart device).
application, or a dedicated device, such as an IoT device (e.g., smart speaker or similar smart device).
[0061] At operation 502, a user inputs a session request for a private communication session with a voice assistant of a web application, such as a private banking session of a banking application of a financial institution to perform banking transactions, on the voice assistant device 200. The session request is made verbally by the user in the form of a voice input that is received by the microphone 240 of the voice assistant device 200. Alternatively, the session request may be input via another input device, such as a touchscreen, with the communication session with the web application to be performed verbally.
Alternatively, the session request may be input via another electronic device connected to the device 200, such as a wireless mobile communication device (e.g., smartphone, tablet, laptop computer or the like) wirelessly connected to the voice assistant device 200.
Alternatively, the session request may be input via another electronic device connected to the device 200, such as a wireless mobile communication device (e.g., smartphone, tablet, laptop computer or the like) wirelessly connected to the voice assistant device 200.
[0062] The processor 205 of the voice assistant device 200 receives and interprets the voice input, and the session request is detected by the voice assistant device 200. Interpreting the voice input by the voice assistant device 200 comprises performing voice recognition (i.e., speaker verification) to identify one or more words in the voice sample, matching the one or more words to a command (or instruction) and optionally one or more parameters (or conditions) for executing the command depending on the matching command (or instruction).
[0063] Voice assistants typically perform speech recognition and do not perform voice recognition. Speech recognition is the process of converting a speech into words. Voice recognition is the process of identifying a person who is speaking.
Voice recognition works by analyzing the features of speech that differ between individuals. Every person has a unique pattern of speech that results from anatomy (e.g., size and shape of the mouth and throat, etc.) and behavioral patterns (voice's pitch, speaking style such as intonation, accent, dialect/vocabulary, etc.).
Speaker verification is a form of voice recognition in which a person's voice is used to verify the identity of the person. With a suitable sample of a user's speech, a person's speech patterns can be tested against the sample to determine if the voice matches, and if so, the person's identify is verified. Speaker identification is a form of voice recognition in which an unknown speaker's identity is determined by comparing a sample against a database of samples until a match is found.

[0064] At operation 504, the processor 205 of the voice assistant device 200 generates an API call for the session request. The API call is sent by the voice assistant device 200 to the voice assistant server 305 via the communication subsystem 225, typically via wireless transceivers. The voice assistant server forwards the API call to the web application server 315 providing the web application and its communication service, such as the banking session for the banking application of the financial instruction. Alternatively, in other embodiments the API call is sent by the voice assistant device 200 directly to the web application server 315 without a voice assistant server 305.
[0065] At operation 506, the authorization server API 325 of the web application server 315 generates a user authentication request in response to the session request, and sends the user authentication request to the voice assistant device 200 via the voice assistant server 305. The web application server 315 typically requires a specific form of user authentication. However, the web application server 315 could permit user authentication in one of a number of approved forms of user authentication. User authentication may be performed via user credentials, such as a combination of user name and shared secret (e.g., password, passcode, PIN, security question answers or the like), biometric authentication, a digital identifier (ID) protocol or a combination thereof among other possibilities.
[0066] The web application server 315 may send the user authentication request to the voice assistant device 200 indirectly via the voice assistant server 305 when user authentication is to be provided by voice input via the microphone 240 or directly when the user authentication can be provided by other means, such as an alternative input device on the voice assistant device 200 such as a biometric sensor 210, camera 230, or input device touchscreen or keyboard.
[0067] At operation 508, the voice assistant device 200 prompts the user to authenticate themselves via one or more first criteria using an identification process. The one or more first criteria may comprise a shared secret and one or more biometric factors, as described more fully below. The prompt is typically an audible announcement via the speaker 245 but could be via a display of the voice assistant device 200 depending on the capabilities and configuration of the voice assistant device 200.
[0068] At operation 510, the user provides input for authentication that is sent to the authorization server API 325 for verification either directly or indirectly via the voice assistant server 305. Alternatively, the verification could be performed locally on the voice assistant device 200. This may be preferable when the one or more first criteria comprises biometric factors, such as voice or facial recognition, for increased security by ensuring that biometric data, such as biometric samples, biometric patterns and/or biometric matching criteria used for comparison, are stored locally. The local storage of biometric data reduces the likelihood that biometric data may be exposed compared with storing biometric data on the authorization server API 325 which is more likely to be hacked or otherwise compromised.
[0069] The one or more first criteria may comprise a shared secret and one or more biometric factors acquired during the input via a keyboard of the voice assistant device 200 in some examples. This is sometimes known as multi-form criteria. The biometric factors may comprise typing cadence, fingerprint recognition, voice recognition, facial recognition, or a combination thereof. Typing cadence may be captured by a hardware or software (virtual) keyboard. Fingerprints may be captured by a fingering sensor which may be embedded within an input device such as a home button of the voice assistant device 200 or touchscreen of the voice assistant device 200 when the keyboard is a software keyboard. Voice samples for voice recognition may be captured by a microphone of the voice assistant device 200, sensors 110 in the local environment, or possibly a connected electronic device 400 such as the user's smartphone. Images for facial recognition may be captured by a camera of the voice assistant device 200, sensors 110 in the local environment, or possibly a connected electronic device 400 such as the user's smartphone.
[0070] At operation 512, the authorization server API 325 attempts to verify the received user input to authenticate the user.
[0071] If the user input does not match stored authentication criteria, authentication fails and a notification is sent to the voice assistant device 200 either directly or indirectly, for example via the voice assistant server 305 (operation 514). The notification concerning the results of the authentication process is provided to the user via the voice assistant device 200, typically by an audible notification via the speakers 245 but possibly via a display of the voice assistant device 200 depending on the capabilities and configuration of the voice assistant device 200. The user may be prompted to try again in response to a failed authentication, possibly up to a permitted number of attempts before a lockout or other security measure is performed, for example by the voice assistant device and/or authorization server API 325.
[0072] At operation 514, the authorization server API 325 determines if any attempts in the permitted number of attempts are remaining (e.g., is the number of attempts < n, where n is the permitted number of attempts). If one or more attempts in the permitted number of attempts are remaining, the voice assistant device 200 again prompts the user to authenticate themselves. If no attempts are remaining, the method 500 ends.
[0073] Alternatively, or in addition to restricting the permitted number of attempts, the authorization server API 325 may determine (e.g., calculate) a probability (or confidence level) of fraudulent activity during the authentication/authorization process. The determination of a probability of fraudulent activity may be performed in a variety of ways including but not limited to checking a biofactor during user input, e.g., typing cadence or fingerprint during input of a shared secret via a hardware or software keyboard or voice recognition during input of a shared secret via a speech recognition). In addition to, or instead of checking a biofactor, the determination of a probability of fraudulent activity may be based on a software daemon (e.g., background software service or agent) that monitors for and detects malicious software attempting to bypass or circumvent the authentication/authorization process. If the determined probability of fraudulent activity exceeds a fraudulent activity threshold, the number of remaining attempts may be reduced by a predetermined amount, which may depend on the determined probability of fraudulent activity. For example, if the determined probability of fraudulent activity exceeds 35% but is less than 50%, the number of remaining attempts may be reduced by 1 or 2 attempts, whereas if the determined probability of fraudulent activity exceeds 50%, the number of remaining attempts may be reduced by 5 attempts or to no remaining attempts.
[0074] If the user input matches stored authentication criteria, authentication is successful, a notification is sent to the voice assistant device 200 either directly or indirectly, for example via the voice assistant server 305, and the communication session with the voice assistant is initiated in response to the .. successful authentication of the user (operation 516). In response to successful authentication, the user may be notified that a private communication session has been initiated with the user's private data (such as banking and/or personal information) and may provide the user with instructions to assist in ensuring that the local environment 101 of the user is private. The meaning of the term "private"
may vary depending on the embodiment. The term "private" may mean that (i) the authenticated user is alone in the local environment 101, (ii) that more than one person is present in the local environment 101 but that any other persons in the local environment 101 other than the authenticated user are authorized users (i.e., only authorized persons are present in the local environment 101), (iii) that more than one person is present in the local environment 101 but that any other persons in the local environment 101 other than the authenticated user are authorized users and are more than a threshold distance away (e.g., other authorized users are permitted with the threshold distance), or (iv) that any additional persons other than the authenticated user are more than a threshold distance away regardless of whether such users are authorized users, depending on the embodiment, as described more fully below.
may vary depending on the embodiment. The term "private" may mean that (i) the authenticated user is alone in the local environment 101, (ii) that more than one person is present in the local environment 101 but that any other persons in the local environment 101 other than the authenticated user are authorized users (i.e., only authorized persons are present in the local environment 101), (iii) that more than one person is present in the local environment 101 but that any other persons in the local environment 101 other than the authenticated user are authorized users and are more than a threshold distance away (e.g., other authorized users are permitted with the threshold distance), or (iv) that any additional persons other than the authenticated user are more than a threshold distance away regardless of whether such users are authorized users, depending on the embodiment, as described more fully below.
[0075] At one or more times after the communication session with the voice assistant has been initiated, the privacy of the vicinity around the authenticated user/voice assistant device 200 is determined by the voice assistant device 200.
That is, the voice assistant device 200 determines whether the vicinity (i.e., the local environment 101) around the authenticated user/voice assistant device 200 is private. This comprises collecting and analyzing sensor data acquired by one or more sensors 110 in the local environment, incorporated within the voice assistant device 200, or possibly incorporated within a connected electronic device 400 such as a user's smartphone. The voice assistant device 200 may also determine whether the local environment 101 around the authenticated user/voice assistant device 200 is private before initiating the communication session in some embodiments.
That is, the voice assistant device 200 determines whether the vicinity (i.e., the local environment 101) around the authenticated user/voice assistant device 200 is private. This comprises collecting and analyzing sensor data acquired by one or more sensors 110 in the local environment, incorporated within the voice assistant device 200, or possibly incorporated within a connected electronic device 400 such as a user's smartphone. The voice assistant device 200 may also determine whether the local environment 101 around the authenticated user/voice assistant device 200 is private before initiating the communication session in some embodiments.
[0076] The privacy of the environment 101 may be determined before or at the start of the communication session and at regular intervals thereafter, possibly continuously or substantially continuously. The term "continuously" means at every opportunity or sample, which may vary depending on the sensor data used to determine the privacy of the environment 101 and the capabilities of the device analysing the sensor data. For example, if the privacy of the environment 101 is determined by voice recognition, privacy may be determined at each voice sample/voice input received by the voice assistant device 200. A voice sample/input may be a discrete input, such as a command or instruction by the user or response, a sentence, a word or suitably sized voice sample, depending on the capabilities of the device analysing the sensor data.
[0077] At operation 518, to determine the privacy of the environment 101, sensor data is acquired by one or more sensors, which may be fixed or mobile depending on the nature of the sensors, such as the host device. The sensors may comprise one or more sensors of the plurality of sensors 215, one or more sensors in the plurality of sensors 110 located in the environment 101, one or more sensors 415 of a connected electronic device 400 such as user's smartphone, or a combination thereof. The processor 205 processes the sensor data acquired by the sensors 110, 215, and/or 415 to determine whether a person is present in the local environment 101 and/or a number of persons present in the local environment of the voice assistant device 200 via one or more second criteria (operation 520).
Alternatively, the sensor data may be sent to a remote server for processing.
Alternatively, the sensor data may be sent to a remote server for processing.
[0078] The one or more second criteria may comprise multiple factors to provide multifactor privacy monitoring. For example, voice recognition and object (person) recognition or facial recognition may be performed to determine a number of persons, and optionally to verify and/or identify those persons. The use of secrets (such as a password, passcode, PIN, security question answers or the like) in combination with biometrics is advantageous in that biometrics may be publically exposed and can be detected by determined attackers. Thus, multi-form criteria, such as two-form criteria comprising secrets and biometrics, may be used for the one or more second criteria to determine a number of persons and optionally to verify and/or identify those persons. Two-form criteria comprising secrets and biometrics may also be used as the one or more first criteria to authenticate the user, as described above.
[0079] The one or more second criteria used to determine whether a person is present in the local environment 101 and/or a number of persons in the local environment 101 of the voice assistant device 200 may be different from the one or more first criteria used to authenticate the user to increase security. For example, the one or more first criteria may be user credentials, such as a username and shared secret, and the one or more second criteria may be a biometric factor.
For another example, the one or more first criteria may be user credentials and one or more biometric factors whereas the one or more second criteria may be one or more different biometric factors. For a further example, the one or more first criteria may be user credentials and one or more biometric factors whereas the one or more second criteria may be the biometric factors of the one or more first criteria.
For another example, the one or more first criteria may be user credentials and one or more biometric factors whereas the one or more second criteria may be one or more different biometric factors. For a further example, the one or more first criteria may be user credentials and one or more biometric factors whereas the one or more second criteria may be the biometric factors of the one or more first criteria.
[0080] The sensor data used to determine whether a person is present in the local environment 101 and/or a number of persons in the environment may comprise one or a combination of a facial data, voice data, IR heat sensor data, movement sensor data, device detection event data, wireless (or wired) device usage data or other data, depending on the embodiment. The use of voice recognition and possibly other factors is advantageous because voice samples are regularly being gathered as part of the communication session with the voice assistant. Therefore, in at least some embodiments the sensor data comprises voice data.
[0081] The sensor data is analyzed by comparing the acquired data to reference data to determine a number of discrete, identified sources. For one example, the sensor data may be used to determine whether a person is present in the local environment 101 and/or a number of persons present in the local environment by performing object (person) recognition on images captured by the camera 130, 230 and/or 430.
[0082] For another example, the sensor data may be used to determine whether a person is present in the local environment 101 and/or a number of faces present in images captured by the camera 130, 230 and/or 430 by performing facial recognition on images captured by the camera 130, 230 and/or 430, with unique faces being a proxy for persons.
[0083] For yet another example, the sensor data may be used to determine whether a person is present in the local environment 101 and/or a number of voices in audio samples captured by the microphone 140, 240 and/or 440 by performing voice recognition on audio samples captured by the microphone 140, 240 and/or 440, with unique voices being a proxy for persons.
[0084] For yet another example, the sensor data may be used to determine whether a person is present in the local environment 101 and/or a number of persons present in the local environment 101 by identifying human heat signatures in IR image(s) captured by the IR sensor 150, 250 and/or 450 by comparing the IR
image(s) to a human heat signature profile via heat pattern analysis, with human heat signatures being a proxy for persons.
image(s) to a human heat signature profile via heat pattern analysis, with human heat signatures being a proxy for persons.
[0085] For yet another example, the sensor data may be used to determine whether a person is present in the local environment 101 and/or a number of persons present in the local environment 101 by identifying a number sources of movements in motion data captured by the motions sensor 120, 220 and/or 420 by comparing the motion data to a human movement profile via movement analysis, with human heat signatures being a proxy for persons.
[0086] For yet another example, the sensor data may be used to determine whether a person is present in the local environment 101 and/or a number of persons present in the local environment 101 by detecting wireless communication devices in the local environment 101 and determining the number of wireless communication devices, with unique wireless communication devices being a proxy for persons. The wireless communication devices may be smartphones in some embodiments. The wireless communication devices may be detected in a number of different ways. The wireless communication devices may be detected by the voice assistant device 200, connected electronic device 400 or sensor array 110 when the wireless communication devices are connected to a short-range and/or long-range wireless communication network in the local environment 101 using suitable detecting means. For example, the wireless communication devices may be detected by detecting the wireless communication devices on the short-range and/or long-range wireless communication network, or by detecting a beacon message, broadcast message or other message sent by the wireless communication devices when connecting to or using the short-range and/or long-range wireless communication network via a short-range and/or long-range wireless communication protocol (e.g., RFID, NFCTM, BluetoothTM, WiFITM, cellular, etc.) when the wireless communication devices are in, or enter, the local environment 101. The message may be detected by a sensor or communication subsystem of the voice assistant device 200 (such as the communication subsystem 225 or data usage monitor and analyzer 270), electronic device 400 or sensor array 110.
[0087] The wireless communication devices in the local environment 101 can be identified by a device identifier (ID) in the transmitted message, such as a media access control (MAC) address, universally unique identifier (UUID), International Mobile Subscriber Identity (IMSI), personal identification number (PIN), etc., with the number of unique device IDs being used to determine the number of unique wireless communication devices.
[0088] The privacy module, to determine the number of persons in the local environment 101, monitors for and detects wireless communication devices in the local environment 101 of the voice assistant device 200, each wireless communication device in the local environment of the voice assistant device being counted as a person in the local environment 101 of the voice assistant device 200. The count of the number of devices in the local environment 101 of the voice assistant device 200 may be adjusted to take into account electronic devices 400 of the authenticated user, for example, using the device ID of the electronic devices 400. The device ID of the electronic devices 400 may be provided in advance, for example, during a setup procedure, so that electronic devices 400 of the authenticated user are not included in the count of the number of devices in the local environment 101 of the voice assistant device 200, or are deduced from the count when present in the local environment 101 of the voice assistant device 200.
[0089] For yet another example, the sensor data may be used to determine whether a person is present in the local environment 101 and/or a number of .. persons present in the local environment 101 by identifying a number of active data users (as opposed to communication devices, which may be active with or without a user) by performing data usage analysis on the data usage information captured by the data usage monitor and analyzer 270, with active data users being a proxy for persons.
[0090] When one person is present in the local environment 101 of the voice assistant device 200, the sensor data is processed to identify (or attempt to identify) the one person and determine whether the one person is the authenticated user based on whether the one person is identified as the authenticated user (operation 522). In some embodiments, voice recognition and optionally facial recognition or other biometric factors are used to identify the person. Voice recognition is advantageous because voice samples are regularly being gathered as part of the communication session with the voice assistant. The voice assistant device 200 may use the previously sensed data and the one or more first criteria or a subset of the one or more first criteria to identify (or attempt to identify) the person, or acquire new sensor data to identify (or attempt to identify) the one person. For example, the voice assistant device 200 may use voice recognition and optionally facial recognition as one or more second criteria to identify the person while using a shared secret and optionally a biometric factor as the one or more first criteria to authenticate the user.
[0091] When the one person in the local environment 101 of the voice assistant device 200 is determined to be the authenticated user, communication of private data by the voice assistant is enabled (operation 524). When the one person in the local environment 101 of the voice assistant device 200 is determined not to be the authenticated user, communication of private data by the voice assistant is disabled (operation 526). The data that is considered to be private data is determined by business rules of the authorization server API 325 and/or resource server API 335, which may vary between embodiments. For example, in some embodiments private data may comprise all banking data and personal data associated the authenticated user whereas non-private data may comprise information not associated with any user, such as local branch information (e.g., address and business hours), general contact information (e.g., toll free telephone number), etc.
[0092] When no one is present in the local environment 101 of the voice assistant device 200, communication of private data by the voice assistant may also be disabled (operation 526).
[0093] When more than one person is present in the local environment 101 of the voice assistant device 200, the sensor data is processed to determine whether the local environment 101 of the voice assistant device 200 matches one or more predetermined privacy criteria for a multi-person environment (operation 530).
The one or more predetermined privacy criteria for a multi-person environment may involve assessing whether the local environment 101 is "private". The term "private" in the context of a multi-person environment may be that only authorized persons are present, that unauthorized persons are more than a threshold distance away, or that any persons other than the authorized users are more than a threshold distance away, as described more fully below. The one or more predetermined privacy criteria for a multi-person environment may comprise each person in the local environment 101 of the voice assistant device 200 being an authorized user, each person other than the authenticated user being more than a threshold distance from the authenticated user, or a combination thereof (i.e., any person within the threshold distance must be an authorized user).
The one or more predetermined privacy criteria for a multi-person environment may involve assessing whether the local environment 101 is "private". The term "private" in the context of a multi-person environment may be that only authorized persons are present, that unauthorized persons are more than a threshold distance away, or that any persons other than the authorized users are more than a threshold distance away, as described more fully below. The one or more predetermined privacy criteria for a multi-person environment may comprise each person in the local environment 101 of the voice assistant device 200 being an authorized user, each person other than the authenticated user being more than a threshold distance from the authenticated user, or a combination thereof (i.e., any person within the threshold distance must be an authorized user).
[0094] The assessment of whether the multi-person environment is "private may consider the geolocation of the voice assistant device 200. In some examples, if the geolocation of the multi-person environment is "private", other persons may be present but if the geolocation of the multi-person environment is not "private", no other persons may be present. In some examples, if the geolocation of the multi-person environment is "private", other persons may be present only if each person in the local environment 101 of the voice assistant device 200 is an authorized user whereas in other examples the other persons need not be an authorized user.
[0095] The voice assistant device 200 may use GPS data, or triangulation via cellular or WLAN access, to determine its geolocation if unknown, and determine whether the geolocation is "private". The determination of whether the determined geolocation is "private" may comprise comparing the determined geolocation to a list of geolocation designated as "private", and determining whether the determined geolocation matches a "private" geolocation. A determined geolocation may be determined to match a "private" geolocation when it falls within a geofence defined for the "private" geolocation. A geofence is a virtual perimeter defined by a particular geographic area using geo-spatial coordinates, such as latitude and longitude. The "private" geolocations may be a room or number of rooms of a house, hotel, apartment of condo building, an entire house, a hotel, or apartment of condo building, a vehicle, or other comparable location. The determined geolocations and "private" geolocations are defined in terms of a geographic coordinate system that depends on the method of determining the geolocation. A
common choice of coordinates is latitude, longitude and optionally elevation.
For example, when GPS is used to determine the geolocation, the geolocation may be defined in terms of latitude and longitude, the values of which may be specified in one of a number of different formats including degrees minutes seconds (DMS), degrees decimal minutes (DDM), or decimal degrees (DD).

For example, when GPS is used to determine the geolocation, the geolocation may be defined in terms of latitude and longitude, the values of which may be specified in one of a number of different formats including degrees minutes seconds (DMS), degrees decimal minutes (DDM), or decimal degrees (DD).
[0096] Whether a particular geolocation is private may be pre-set by the user or a third party service such as the voice assistant server 305 and a web application server 315. Alternatively, whether a particular geolocation is private may be determined dynamically in real-time, for example, by the voice assistant device 200, voice assistant server 305 or web application server 315, or possibly by prompting a user, depending on the embodiment. Each "private" geolocation may have a common name for easy identification by a user, such as "home", "work", "school", "car", "Mom's house", "cottage", etc. When the "private" geolocation is a mobile location such as a vehicle, the geofence that defines the "private"
geolocation is determined dynamically. Additional factors may be used to identify or locate a mobile location, such as a smart tag (e.g., NFC tag or similar short-range wireless communication tag), wireless data activity, etc.

[0097] In operation 530, determining whether the local environment 101 of the voice assistant device 200 matches one or more predetermined privacy criteria for a multi-person environment, may be implemented in a variety of ways. The voice assistant device 200, when more than one person is present in the local environment 101 of the voice assistant device 200, may sense the local environment 101 of the voice assistant device 200 via the plurality of sensors 110, 215 or 415 to generate sensed data. The sensed data may comprise motion data from motion sensors 120, 220 or 420, images from cameras 130, 230 or 430, audio samples from the microphones 140, 240 or 440, IR data from IR sensors 150, 250 or 450, proximity data from proximity sensors 160, 260 or 460, or a combination thereof.
[0098] Referring to FIG. 9, one embodiment of a method 900 for determining whether the local environment 101 of the voice assistant device 200 matches one or more predetermined privacy criteria for a multi-person environment in accordance with the present disclosure will be described. The method 900 presents one method of accommodating multiple people in an environment, such as multiple people living in a home. In operation 905, a probability (or confidence level) that private information audibly communicated by the voice assistant device 200 may be heard by any of the other persons present in the local environment 101 (e.g., the one or more additional persons in the vicinity of the authenticated user) is determined (e.g., calculated) using the sensed data. The probability, known as an audibility probability, is used by the voice assistant device 200 as a threshold to determine whether the communication session should end or whether some action should be taken for handling private data when the local environment 101 of the voice assistant device 200 is determined to be non-private, as described more fully below in connection with FIG. 5-8. The determination that private information audibly communicated by the voice assistant device 200 may be heard by any of the other persons present in the local environment 101 may be performed in a variety of ways, examples of which are described below.
[0099] In operation 910, the voice assistant device 200 compares the determined audibility probability to an audibility probability threshold. The audibility probability threshold may vary between embodiments. The audibility probability threshold may vary based on a privacy setting (or rating) or security setting (or rating) for the communication session or the application associated therewith.
For example, if the communication session or application associated therewith has a privacy setting of "high" (e.g., for a banking communication session for a banking application), a lower audibility probability threshold may be used than if the communication session or application associated therewith had a privacy setting of "low". In this way a stricter standard is applied if the communication session or application associated therewith has more private or sensitive data. "high"
For example, if the communication session or application associated therewith has a privacy setting of "high" (e.g., for a banking communication session for a banking application), a lower audibility probability threshold may be used than if the communication session or application associated therewith had a privacy setting of "low". In this way a stricter standard is applied if the communication session or application associated therewith has more private or sensitive data. "high"
[00100] The audibility probability threshold may vary based on the number and/or type of sensor data use to determine the audibility probability. For example, when more than one type of sense data is used to determine the audibility probability, the accuracy of the audibility probability may be increased and a lower audibility probability may be used. For one example, if audio data captured by a microphone and image data captured by a camera are used to determine the audibility probability, a lower audibility probability threshold may be used than if only image data is used to determine the audibility probability. For another example, if audio data captured by a microphone is used to determine the audibility probability, a lower audibility probability threshold may be used than if image data captured by a camera is used to determine the audibility probability because audio data is more accurate.
[00101] At operation 915, when the audibility probability is determined to be greater than or equal to an audibility probability threshold, the local environment 101 of the voice assistant device 200 is determined not to match the one or more predetermined privacy criteria for a multi-person environment.
[00102] At operation 920, when the audibility probability is determined to be less than the audibility probability threshold, the local environment 101 of the voice assistant device 200 is determined to match the one or more predetermined privacy criteria for a multi-person environment.
[00103] The voice assistant device 200 may generate a three-dimensional (3D) model of the local environment 101 using the sensed data in the operation 530 as part of a method of determining whether private information audibly communicated by the voice assistant device 200 may be heard by any of the other persons present in the local environment 101. In one example in which the sensed data comprises images from cameras 130 or 230. The voice assistant device 200 acquires, via the one or more cameras 130 or 230, one or more images of the local environment of the voice assistant device 200. The cameras 130 or 230 may be stereoscopic cameras, omnidirectional cameras, rotating cameras, or a 3D scanner. One or more reference points in the one or more images of the local environment 101 of the voice assistant device 200 are identified by the processor 205. A distance to the one or more reference points is determined by the processor 205 via proximity data sensed by the one or more proximity sensors 160 or 260. A 3D model of the local environment 101 of the voice assistant device 200 is determined using the one or more images and the distance to the one or more reference points.
[00104] In another example in which the sensed data comprises images audio samples from the microphones 140 or 240, the voice assistant device 200 generates, via the speaker 245, a multi-tone signal. The voice assistant device 200 receives, via the microphone 140 or 240, a reflected multi-tone signal. A 3D
model of the local environment 101 of the voice assistant device 200 is generated by the processor 205 using the multi-tone signal and the reflected multi-tone signal.
model of the local environment 101 of the voice assistant device 200 is generated by the processor 205 using the multi-tone signal and the reflected multi-tone signal.
[00105] After the 3D model of the local environment 101 of the voice assistant device 200 is generated using one of the approaches described above or other suitable process, an audio profile of the local environment 101 is generated based on the three-dimensional model and an audio sample of the local environment 101.
The audio profile defines a sound transmission pattern within the local environment 101 given its 3D shape as defined by the 3D model of the local environment 101.
The audio profile of the local environment is based on the 3D model and an audio sample of the local environment 101.
The audio profile defines a sound transmission pattern within the local environment 101 given its 3D shape as defined by the 3D model of the local environment 101.
The audio profile of the local environment is based on the 3D model and an audio sample of the local environment 101.
[00106] Next, an audible transmission distance of the voice of the authenticated user is determined based on the audio profile of the local environment 101 as the threshold distance. The audible transmission distance determines a distance from the authenticated user within which the voice of the authenticated user is discernable to other persons in the local environment 101.
The audible transmission distance of the voice of the authenticated user is based on the audio profile and one or more characteristics of the voice of the authenticated user, such as voice's pitch, speaking style such as intonation, accent, dialect/vocabulary, etc.
The audible transmission distance of the voice of the authenticated user is based on the audio profile and one or more characteristics of the voice of the authenticated user, such as voice's pitch, speaking style such as intonation, accent, dialect/vocabulary, etc.
[00107] Next, all persons in the local environment 101 are localized via the sensed data, i.e. a relative position of the persons in the local environment 101 is determined. Lastly, for each person other than the authenticated user, a distance of the person from the authenticated user is determined. When the distance of one or more other persons from the authenticated user is more than the audible transmission distance, the local environment 101 of the voice assistant device is determined not to match the one or more predetermined privacy criteria for a multi-person environment (i.e., the local environment 101 is determined to be non-private). When the distance of each of other persons from the authenticated user is less than the audible transmission distance, the local environment 101 of the voice assistant device 200 is determined to match the one or more predetermined privacy criteria for a multi-person environment (i.e., the local environment 101 is determined to be private). Alternatively, an audibility probability may be determined (i.e., calculated) based on the distance of the person from the authenticated user and the the audible transmission distance and tested against an audibility probability threshold as described above in connection with FIG. 9.
The audibility probability may be a relative measure of the distance of each person from the authenticated user and the audible transmission distance, such as a percentage.
The audibility probability may be a relative measure of the distance of each person from the authenticated user and the audible transmission distance, such as a percentage.
[00108] When the local environment 101 of the voice assistant device 200 is determined to match the one or more predetermined privacy criteria for a multi-person environment, communication of private data by the voice assistant is enabled (operation 524). When the local environment 101 of the voice assistant device 200 is determined not to match the one or more predetermined privacy criteria for a multi-person environment, communication of private data by the voice assistant is disabled (operation 526).
[00109] The method 500 ends when the communication session ends or the number of permitted authorization attempts is reached (operation 532).
Otherwise, the method 500 continues with the voice assistant device 200 sensing the environment 101 and evaluating the results at regular intervals to determine whether the communication session is private.
Otherwise, the method 500 continues with the voice assistant device 200 sensing the environment 101 and evaluating the results at regular intervals to determine whether the communication session is private.
[00110] The voice assistant device 200 sends the result of the privacy analysis and determination to the web application server 315 directly or indirectly via the voice assistant server 305. When the local environment 101 of the voice assistant device 200 is determined to be private, the web application server 315 generates session token which is sent to the voice assistant server 305 to authorize the voice assistant of the voice assistant server 305 to access private data stored by the authorization server API 325 and/or resource server API 335, such as banking information. The session token may expire after a predetermined time interval so that, if a subsequent privacy check fails, the security token will no longer be valid and the voice assistant server 305 will no longer access to private data stored by the authorization server API 325 and/or resource server API 335. The time interval for which the security token is valid may be very short to facilitate continuous privacy monitoring.
[00111] Referring next to FIG. 5, a method 700 of handling private data when the local environment 101 of the voice assistant device 200 is determined to be non-private will be described. The method 700 is performed by a voice assistant device 200 which, as noted above, may be a multipurpose communication device, such as a smartphone or tablet running a VA application, or a dedicated device, such as an IoT device (e.g., smart speaker or similar smart device). The local environment 101 of the voice assistant device 200 may be determined to be non-private in a number of ways, as described herein. For example, the local environment 101 of the voice assistant device 200 may be determined to be non-private in that more than one person is determined to be in the local environment, when one person is determined to be in the local environment 101 of the voice assistant device 200 but that one person is determined not to be the authenticated user, or when the local environment of the electronic device is determined not to match the one or more predetermined privacy criteria for a multi-person environment.
[00112] The voice assistant device 200 generates, via the speaker 245 of the voice assistant device 200, an audible notification that the communication session is not private (operation 702). The notification may comprise a voice prompt whether to continue the communication session via a different channel or continue the communication session from a private location, such as a call back, transfer of the communication session to another electronic device 400, such as a mobile phone, or suspending the communication session so that the user can relocate.
[00113] The voice assistant device 200 receives a voice input via the microphone 240 (operation 704). The processor 205 parses, via speech recognition, the voice input to extract a command to be performed from a plurality of commands (operation 706). The processor 205 then determines a matching command (operation 708). The voice assistant device 200 transfers the communication session to a second electronic device 400 in response to the voice input containing a first command (operation 710). The voice assistant device initiates a call back to a designated telephone number in response to the voice input containing a second command, and ends the communication session (operation 712). The voice assistant device 200 temporarily suspends the communication session in response to the voice input containing a third command (operation 714).
[00114] While the communication session is temporarily suspended, the voice assistant device 200 may receive a voice input via the microphone 240 (operation 716). Next, the voice assistant device 200 parses, via speech recognition, the voice input to extract a command to be performed from a plurality of commands (operation 718). The processor 205 then determines a matching command (operation 720). The voice assistant device 200 may resume the communication session from the temporary suspension in response to the voice input containing a corresponding command (operation 722).
[00115] FIG. 6 illustrates another embodiment of a method 750 of handling private data when the local environment 101 of the voice assistant device 200 is determined to be non-private will be described. The method 800 is similar to the method 700 except that while the communication session is temporarily suspended, the voice assistant device 200 monitors for changes in the location of the voice assistant device 200 (operation 760). When the voice assistant device 200 has moved more than a threshold distance (operation 770), the voice assistant device 200 determines whether the authenticated user has moved to a private location (operation 780). The voice assistant device 200 may automatically resume the communication session from the temporary suspension in response to a determination that the authenticated user has moved to a private location (operation 785). The determination that a location is a private location is based on location data, such as satellite-based location data (e.g., GPS data) or location data derived from sensor data such as proximity data. A location may be determined to be a private location if it is an enclosed room, a designated room or set or location (which may be defined by a set of predefined GPS locations), a new location that is at least a threshold distance from the location at which it was determined that the communication session is not private, among other possibilities.
[00116] FIG. 7 illustrates a further embodiment of a method 800 of handling private data when the local environment 101 of the voice assistant device 200 is determined to be non-private will be described. The voice assistant device 200 generates, via the speaker 245 of the voice assistant device 200, an audible notification that the communication session is not private and comprises a voice prompt whether to continue communication of private data even though the communication session is not private (operation 805). The voice assistant device 200 receives a voice input via the microphone 240 (operation 810). The processor 205 parses, via speech recognition, the voice input to extract a command to be performed from a plurality of commands (operation 815). The processor 205 then determines a matching command (operation 820). The voice assistant device 200 re-enables the communication of private data in response to the voice input containing a corresponding command (operation 825). This allows the user to continue communication of private data even though the communication session is not private, with the user bearing the security risks associated therewith.
[00117] FIG. 8 illustrates a yet further embodiment of a method 850 of handling private data when the local environment 101 of the voice assistant device 200 is determined to be non-private will be described. The voice assistant device 200 generates, via the speaker 245 of the voice assistant device 200, an audible notification that the communication session is not private and comprises a voice prompt whether to continue the communication session with only non-private data (operation 855). The voice assistant device 200 receives a voice input via the microphone 240 (operation 860). The processor 205 parses, via speech recognition, the voice input to extract a command to be performed from a plurality of commands (operation 865). The processor 205 then determines a matching command (operation 870). Next, the voice assistant device 200 may terminate the communication session in response to the voice input containing a corresponding command, or continue the communication session in response to the voice input containing a corresponding command (operation 875).
[00118] The methods 700, 750, 800 and 850 described above that may be performed whenever the local environment 101 of the voice assistant device 200 is determined to be non-private.
[00119] Referring next to FIG. 4, a method 600 of enforcing privacy during a communication session with a voice assistant in accordance with one example embodiment of the present disclosure will be described. The method 600 is similar to the method 500 described above in connection with FIG. 3 with the notable difference that the user of the voice assistant device 200 is not authenticated after the request to initiate a communication session. Because the user of the voice assistant device 200 is not authenticated before initiating the communication session, multi-person support is not permitted for increased security. Thus, when more than one person is present in the environment of the electronic device, communication of private data by the voice assistant is disabled. In other embodiments, multi-person support may be permitted even though the user of the voice assistant device 200 is not authenticated before initiating the communication session.
[00120] In the method 600, when one person is present in the local environment 101 of the voice assistant device 200, the sensor data is processed to identify the one person (operation 520), and determine whether the one person is an authorized user (operation 610). When the one person in the environment is determined to be an authorized user, communication of private data by the voice assistant is enabled (operation 524). When the one person in the environment is determined not to be an authorized user, communication of private data by the voice assistant is disabled (operation 526). When no one is present in the local environment 101 of the voice assistant device 200, communication of private data by the voice assistant may also be disabled (operation 526).
[00121] The method 600 ends when the communication session ends (operation 620). Otherwise, the method 500 continues with the voice assistant device 200 sensing the environment 101 and evaluating the results at regular intervals to determine whether the local environment 101 in which the communication session is being held is private.
[00122] Although the various aspects of the method have been described as being performed by the voice assistant device 200 for the security of user data, in other embodiments processing steps may be performed by the voice assistant server 305, the web application server 315, or other intermediary entity (e.g., server) between the voice assistant device 200 and the web application server 315.
In such alternate embodiments, the voice assistant device 200 merely collects data from the sensors 110 and/or 215, sends the sensor data to the voice assistant server 305, web application server 315 or other intermediary entity for analysis, receives the privacy enforcement instructions, and then applies privacy enforcement instructions.
