Description

Unlocking request response method and mobile terminal

Technical Field

The invention relates to the field of terminals, in particular to an unlocking request response method and a mobile terminal.

Background

With the development of mobile terminal unlocking and encryption technologies and the continuous abundance of application scenarios thereof, biometric identification technologies are gradually introduced into unlocking and encryption applications. From initial password unlocking, pattern unlocking, later fingerprint identification unlocking, iris identification unlocking and the current most fierce Face identification technology (Face ID), unlocking and encryption technology is evolving around two core requirements of safety and easy use.

For the face recognition technology, the principle is as follows: the method comprises the steps of utilizing an optical sensing system of the mobile terminal to collect facial features of a user in advance and storing the facial features into a storage unit of the terminal to form a facial feature database of the user. Then, in the process of face recognition unlocking, the face features of the face in the image acquisition area are acquired and compared and matched with the face features stored in the face feature database. If the matching degree of the two meets a preset matching degree threshold value, unlocking is allowed; and if not, refusing to unlock.

But for unlocking operations which are not subjective and intended by the user, for example: the user is in a state of limited personal freedom, sleeping and the like, the face of the user is placed in an image acquisition area by other people for unlocking operation, and the safe use of the mobile terminal is influenced because the face recognition technology has no 'strength' identification.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

With reference to fig. 1, it should be noted that a first application scenario of the present invention may be:

when holding the mobile terminal for an unlocking operation, the unlocking operation may be, for example: a password, a pattern or a face is input through the touch screen 11 to initiate an unlocking request to the mobile terminal within an image capturing area of the camera 12 of the mobile terminal. When the mobile terminal receives the unlocking request, acquiring holding data of a user holding the mobile terminal; then, the holding data is compared with preset data (also called reference data, for example, habit data of a user holding the mobile terminal before), if the holding data is matched with the reference data, the unlocking operation performed by the user holding the mobile terminal is determined, the mobile terminal is controlled to respond to the unlocking request to determine whether the matching degree of the password, the pattern or the facial features of the user input by the user and the preset password, pattern or facial features can pass the verification, and if so, the mobile terminal is unlocked. And if the holding data is not matched with the reference data, judging that the mobile terminal is not held by the user, and indicating the mobile terminal to refuse to respond to the unlocking request.

A second application scenario of the present invention may be:

the difference between this application scenario and the first application scenario is that, when the unlocking request is received, the mobile terminal is allowed to match a password, a pattern, or a facial feature of the user input by the user, and obtain a matching result. Before obtaining the matching of the password, the pattern or the facial features input by the user and the preset password, pattern or facial features and unlocking, the holding data and the reference data need to be matched to judge whether the mobile terminal is held by the user for unlocking operation, and if so, the mobile terminal is unlocked; if not, the lock is not unlocked.

It is understood that in the application scenario, when the password, the pattern or the facial feature of the user input by the user is not matched with the preset password, pattern or facial feature, it is not necessary to determine whether the mobile terminal is held by the user for unlocking operation, and the unlocking operation is rejected.

In the above two application scenarios, matching between the password and the password, matching between the pattern and the pattern, or matching between the facial features and the facial features are mature technologies, and therefore, the detailed description thereof is omitted here.

In addition, the mobile terminal in the invention refers to a computer device that can be used in mobile, and broadly includes a mobile phone, a notebook, a tablet computer, a POS machine, and even a vehicle-mounted computer. But most often refer to cell phones or smart phones and tablets with multiple application functions.

The technical solutions provided by the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Example 1

Fig. 2 is a schematic flow diagram of an unlocking request response method provided in embodiment 1 of the present invention, and referring to fig. 2, the method may specifically include the following steps:

step 22, when an unlocking request is detected, determining detected holding data, wherein the holding data is used for describing that an application main body for holding operation performed on the mobile terminal is the mobile terminal;

with reference to the above application scenarios, it should be noted that the first implementation manner of step 22 may be:

when the mobile terminal is in a screen locking state, if a user places a face in an image acquisition area of a camera of the mobile terminal, the camera acquires a face image (or face feature data) of the user and sends the face image (or face feature data) to a processor of the mobile terminal in an unlocking request mode. The processor reads the data currently acquired by the holding sensor by taking the unlocking request as a trigger condition, and the data are used as holding data (such as holding position, holding strength and the like) for representing the holding operation of the mobile terminal currently held by the user and describing holding characteristics.

A second implementation of step 22 may be:

when the mobile terminal is in a screen locking state, a user inputs an unlocking password/pattern to the mobile terminal through the touch screen to initiate an unlocking request, a processor of the mobile terminal takes the unlocking request as a trigger condition, and reads data currently acquired by the holding sensor as holding data for describing holding characteristics (such as position, force and the like).

The data collected by the holding sensor at present can be data directly reflecting the holding position and the holding force of a user; or the data indirectly reflecting the holding position and the holding strength of the user based on certain parameters. For example: the pressure sensor is used as one type of holding sensor, the detected pressure value can directly reflect the holding force, the antenna is used as one type of holding sensor, and the parameter value of the characteristic parameter can indirectly reflect the holding position.

Step 24, judging whether the holding data is matched with preset data;

if yes, go to step 26; if not, the unlocking request is not responded, and the step is ended.

It should be noted that, the first implementation manner of step 24 may be:

and matching the holding data with the previously trained habit holding data (reference data) of the user, judging whether the holding data and the habit holding data are matched, and if so, determining that the holding data is the unlocking request of the user in holding the mobile terminal.

A second implementation of step 24 may be:

determining a corresponding unlock type based on the unlock request, for example: face unlocking, password unlocking and pattern unlocking, and finding out corresponding reference data from a pre-established reference database based on an unlocking type, wherein the reference database stores a corresponding relation between the unlocking type and the reference data; and then, matching the holding data with the corresponding reference data to judge whether the holding data and the reference data are matched.

For the second implementation, it is understood that when the user performs unlocking based on different unlocking types, the way of holding the mobile terminal may be greatly changed, for example: when the password is unlocked, the user may need to input the password by using a thumb, so that the thumb is not in contact with the mobile terminal; when the face is unlocked, the user does not need to input the password manually, so that the mobile terminal is generally righted by 5 fingers to be aligned with the face. It can be seen that holding data corresponding to password unlocking and face unlocking are greatly different, and therefore, it is very necessary to set corresponding reference data for different types of unlocking modes, so as to further improve unlocking accuracy and safety.

And step 26, responding to the unlocking request.

It is understood that when the holding data is matched with the reference data, it is determined that the holding data is an unlocking request initiated by the user holding the mobile terminal, so that the mobile terminal performs an operation of verifying the unlocking request in response to the unlocking request, and if the unlocking request passes the verification, the unlocking is successful.

In addition, when the holding data is not matched with the reference data, the mobile terminal judges that the mobile terminal is held by a non-user to initiate an unlocking request, and refuses to respond to the unlocking request.

It can be seen that in the embodiment, when the unlocking request is detected, the holding data of the holding mobile terminal is determined, the holding data is matched with the reference data to determine whether the unlocking request is initiated when the user holds the mobile terminal, and after the user holds the mobile terminal, the mobile terminal responds to the unlocking request, so that the condition that malicious unlocking is not performed by the subjective intention of the user is avoided, and the purpose of improving the unlocking security can be achieved.

Example 2

Fig. 3 is a schematic flowchart of an unlocking request response method provided in embodiment 2 of the present invention, and referring to fig. 3, the method may specifically include the following steps:

step 32, collecting holding data of a user as a sample;

step 34, judging whether the acquisition time length/frequency reaches the preset time length/frequency threshold value

If yes, go to step 36; if not, step 32 is executed again.

Step 36, training the collected holding data to obtain reference data

Step 38, upon detection of an unlocking request, determining the detected grip data

Step 310, judging whether the holding data is matched with the reference data

If yes, go to step 312; if not, the process is ended.

Step 312, responding to the unlocking request.

It should be noted that steps 32 to 36 constitute a training phase of the present embodiment, and steps 38 to 312 constitute an unlocking phase of the present embodiment. The training phase and the unlocking phase are exemplarily described below with facial unlocking as an example:

example one, taking inductor as antenna

Step one, the principle of the present example is explained

For different users, due to the size of the hand, the habit difference of the left hand and the right hand, and other differences, the users have different habits of holding the mobile phone, and further have the difference of holding positions. Thus, different information will be obtained by antenna detection, including but not limited to predetermined parameters such as variations in standing waves, variations in impedance and phase, and variations in equivalent electricity, which are parameters of antenna characteristics.

The mobile terminal acquires the parameter values of the characteristic parameters, stores the parameter values in a storage unit of the mobile terminal, acquires, induces and analyzes data for a certain time or times to obtain the variation range of the relevant characteristic parameters in the daily use process of the user, and maps the variation range into the handheld habit data of the user to serve as second reference data of the subsequent verification step. Then, associating second reference data with stored unlocking verification data (such as facial feature data), when a facial recognition request is detected, acquiring first holding data to be verified through an antenna by the mobile terminal, matching the first holding data with the second reference data, judging whether the first holding data meets a reference range required by the second reference data, and if so, determining that the first holding data and the second holding data are matched and normally responding to the facial recognition request; if not, the two are determined not to match and the response to the facial recognition request is denied.

Step two, the antenna layout of the mobile terminal is explained in detail

Referring to fig. 4a, at present, most antennas of a common mobile terminal are one antenna for the next, and some mobile terminals adopt a multi-antenna design to meet the speed requirement of a future 5G terminal, for example: up to 4 antennas are used to achieve rates above 1Gbps to form a4 × 4 Multiple-Input Multiple-Output (MIMO) system. The typical layout may be up, down, left, and right antennas, corresponding to antenna B42, antenna a41, antenna C43, and antenna D44.

Of course, it is understood that the purpose of this embodiment can be achieved based on the principle in step one no matter the scheme of two antennas is adopted, or the scheme of four antennas is adopted, or even the scheme of other antenna layout modes is adopted, but in order to ensure that the trained handheld habit data of the user has higher precision, the scheme of one antenna is adopted here.

Correspondingly, the characteristic parameters (standing wave, impedance, etc.) of each antenna in the free state (non-hand-held state) are recorded as:

an antenna A: a0;

an antenna B: b0;

an antenna C: c0;

an antenna D: d0;

mapping antenna characteristic parameters to handheld habit data: { A0, B0, C0, D0}

Step three, determining handheld habit data when a user holds a first position

When the user holds the mobile terminal with a hand to enable the camera to capture facial characteristics normally to generate unlock information or payment information, different antenna characteristic information is generated due to the size of the hand and the difference between the held position and the source end position of each antenna. The source end and the tail end of the antenna A41 are respectively marked as 411 and 412, the source end and the tail end of the antenna B42 are respectively marked as 421 and 422, the source end and the tail end of the antenna C43 are respectively marked as 431 and 432, and the source end and the tail end of the antenna D44 are respectively marked as 441 and 442.

Referring to fig. 4b, when the user holds the mobile terminal close to the source end position of the antenna A, C, D (the lower position of the terminal), the characteristic parameters (standing wave, impedance, etc.) of the antenna in the held state are recorded as:

an antenna A: a1;

an antenna B: b1;

an antenna C: c1;

an antenna D: d1;

mapping parameter values of the antenna characteristic parameters into handheld habit data: { A1, B1, C1, D1 }.

Step four, determining the handheld habit data when the user holds the second position

Referring to fig. 4c, when the user holds the position close to the middle position of the antenna C, D (the middle of the terminal), the characteristic parameters of the antenna (standing wave, impedance, etc.) in the held state are recorded as:

an antenna A: a2;

an antenna B: b2;

an antenna C: c2;

an antenna D: d2;

mapping parameter values of the antenna characteristic parameters into handheld habit data: { A2, B2, C2, D2 }.

Step five, repeatedly executing the step of determining the handheld habit data, and training and testing the determined handheld habit data as a sample

Continuously recording the handheld habit data with preset duration/times based on the principle of determining the handheld habit data described in the third step and the fourth step; then, part of the hand-held habit data is: { A1, B1, C1, D1} - { Ax, Bx, Cx, Dx } as training samples, second reference data were constructed based on a predetermined training model. Compare it with part of the hand-held habit data: { A_x1，B_x1，C_x1，D_x1}、{A_x2，B_x2，C_x2，D_x2Either of (A)_x3，B_x3，C_x3Dx3} etc. as test samples, the second reference data is tested.

A first implementation of training and testing the second reference data may be:

based on training samples { a1, B1, C1, D1} - { Ax, Bx, Cx, Dx }, determining a value range of a characteristic parameter corresponding to each antenna, for example: { A2-A8, B3-B5, C1-C9, and D11-D20 }, as second reference data; and then, judging whether the parameter value of the characteristic parameter in the test sample is in the value range, determining the passing rate of the test sample passing the verification according to the judgment result, and correcting the second reference data based on the passing rate.

A second implementation of training and testing the second reference data may be:

based on training samples { A1, B1, C1, D1} - { Ax, Bx, Cx, Dx }, a set of data with higher polymerization degree is determined, for example: { a3, B5, C8, Dx }, as second reference data; then, comparing the similarity between the data corresponding to the test sample and the second reference data, and determining whether the similarity of the two meets a preset threshold value, if so, passing; if not, the result is failed. Then, the second reference data is corrected based on the passing rate.

In this implementation, the aggregation of data and the similarity calculation between data belong to the mature prior art, and are not described herein again.

In addition, as a preferred implementation manner, the embodiment further dynamically updates the second reference data until the data is stable, so as to improve the accuracy. In the process, parameter collection, terminal training and terminal learning are all performed in the background of the terminal, so that normal use of a user is not affected.

Step six, applying the trained handheld habit data

Referring to fig. 4d, when the non-owner holds the mobile terminal to perform malicious operations, so that the image capturing area of the mobile terminal at the face position of the user is inevitably different from the holding data of the user (owner), for example: the holding positions of each person holding the mobile terminal are different.

For example: the antenna characteristic parameters (standing waves, impedance, etc.) for the off-board owner holding the mobile terminal close to the antenna A, B, C, D are recorded as:

an antenna A: a. the_fail；

An antenna B: b is_fail；

An antenna C: c_fail；

An antenna D: d_fail；

Accordingly, the mapped non-owner hand-held habit data: { A_fail，B_fail，C_fail，D_failAnd taking the holding data as first holding data to be verified to represent the holding position of the mobile terminal held by the non-owner. Comparing the first holding data with the second reference data in the fifth step, the two data have larger difference, and are obviously distinguished from the holding habit of the owner.

The comparison of the first holding data and the second reference data is implemented in a similar manner as the comparison of the second reference data and the test sample in the fifth step, for example: the value range (A3-A8) of the standing wave corresponding to the trained antenna A and the standing wave A detected by the antenna A in the holding data_failComparing to determine A_failAnd if the two types of the data belong to the (A3-A8), determining that the two types of the data are matched. Similarly, the value ranges of the standing waves corresponding to other antennas can be respectively equal to B_fail、C_fail、D_failA comparison is made. And if the data match, determining that the holding data match the reference data. Alternatively, if not both match and the degree of deviation is within a predetermined range, the two may be considered to match. Therefore, it will not be described herein.

Similar to the matching rule described above with respect to the single antenna characteristic parameter — standing wave, for the matching rule of a plurality of antenna characteristic parameters, it is briefly described that: the reference data corresponding to each antenna characteristic parameter can be searched from a preset list, then the holding data corresponding to each detected antenna characteristic parameter is determined, the holding data is compared with the searched reference data one by one to obtain the matching result corresponding to each other antenna characteristic parameter, and then whether the holding data is matched with the reference data or not can be determined from the dimension of the antenna characteristic parameter.

Second, take the sensor as the pressure sensor

Step one, the detailed description is carried out on the layout of the pressure sensor of the mobile terminal

Layout mode 1, referring to fig. 5a, the mobile terminal includes a pressure sensor group, and the pressure sensors in the pressure sensor group are disposed on one side, both left side and right side, of the mobile terminal, where the left side is taken as an example.

Layout mode 2, referring to fig. 5b, the mobile terminal includes a first pressure sensor group and a second pressure sensor group, where the pressure sensors in the first pressure sensor group are disposed on a first side (taking the left side as an example) of the mobile terminal, and the pressure sensors in the second pressure sensor group are disposed on a second side (taking the right side as an example) of the mobile terminal.

For the two layouts, the number of pressure sensors is as follows: each pressure sensor group comprises 21 pressure sensors, and correspondingly, the number of the pressure sensor in the first pressure sensor group is A1 and A2 … A21 from top to bottom, and the number of the pressure sensor in the second pressure sensor group is B1 and B2 … B21 from top to bottom; also, the pressure sensor may be provided to extend over the entire side of the mobile terminal, or may be provided within a range that a user can easily grip when holding the mobile terminal for an unlocking operation based on an empirical value. The following description will be made in detail by taking the layout mode 2 as an example:

accordingly, the values of the two sets of pressure sensors recorded in the free state non-hand-held state are:

the first group of pressure sensors: a1₀A2₀A3₀～A21₀

A second group of pressure sensors: b1₀B2₀B3₀～B21₀

Further, mapping the pressure sensor to user hand-held habit data: { A1₀A2₀A3₀～A21₀，B1₀B2₀B3₀～B21₀}。

Step two, determining handheld habit data when a user holds a first position

When a user holds the mobile terminal so that the camera can normally shoot facial features to generate unlocking information or payment information, the pressure sensor obtains different pressure data due to the size of the hand shape and the position difference of the held pressure sensor.

While the user is holding in the first position shown in fig. 5c, the pressure sensor pressure values are recorded as:

a pressure sensor A: a1₁A2₁A3_1～A21₁

A pressure sensor B: b1₁B2₁B3_1～B21₁

Further, mapping obtains user handheld habit data: { A1₁A2₁A3_1～A21₁，B1₁B2₁B3_1～B21₁}。

Step three, determining the handheld habit data when the user holds the second position

When the user holds in the second position shown in fig. 5d (near the middle-lower portion of the mobile terminal), the respective pressure sensor pressure values are recorded as:

a pressure sensor A: a1₂A2₂A3_2～A21₂

A pressure sensor B: b1₂B2₂B3_2～B21₂

Further, mapping obtains user handheld habit data: { A1₂A2₂A3_2～A21₂，B1₂B2₂B3_2～B21₂}

Step four, repeatedly executing the step of determining the handheld habit data, and training and testing the determined handheld habit data as a sample

And acquiring pressure data with preset time length/times based on the steps similar to the step two and the step three, and mapping to obtain multiple groups of handheld habit data. Then, part of the handheld habit data is used as a training sample to train a group of handheld habit data with the highest aggregation degree, or a pressure range corresponding to each pressure sensor is constructed to be used as first reference data, and the holding position and the holding strength when the user holds the mobile terminal are represented based on the position of the pressure sensor and the detected pressure value. And then, testing and correcting the trained reference data by using the remaining part of the handheld habit data as a test sample until the predetermined test precision is met.

Step six, applying the trained first reference data

When a non-owner holds the mobile terminal to perform malicious operation so as to enable the image acquisition area of the mobile terminal to be positioned on the face of a user, the holding data of the mobile terminal is inevitably different from the holding habit data of the user (owner).

Referring to fig. 5e, if the owner is not in the third position, the pressure sensor of the holding state records:

a pressure sensor A: a1_failA2_failA3_fail～A21_fail

A pressure sensor B: b1_failB2_failB3_fail～B21_fail

And further, obtaining mapped second holding data to be verified: { A1_failA2_failA3_fail～A21_fail，B1_failB2_failB3_fail～B21_failAnd representing the holding position and the holding force when the non-owner user holds the mobile terminal by using the position based on the pressure sensor and the pressure value detected by the pressure sensor.

And comparing the second holding data to be verified with the first reference data to obtain that the second holding data and the first reference data have a larger difference, and further determining that the unlocking operation is initiated by the non-owner.

A first implementation manner for comparing the second holding data with the first reference data may be:

comparing the second holding data with the first reference data to obtain the similarity between the second holding data and the first reference data; judging whether the similarity between the second holding data and the first reference data meets a preset similarity threshold value or not; if not, determining that the second holding data is not matched with the first reference data, and further determining that the unlocking operation is initiated by a non-owner; and if so, determining that the second holding data is matched with the first reference data, and further determining that the unlocking operation is initiated by the owner.

For the first implementation manner, it should be noted that the comparison between the second holding data and the first reference data is actually a comparison between one set of data and another set of data, and since the specific comparison scheme can be performed by using the prior art, the specific implementation method is not limited herein.

A second implementation manner for comparing the second holding data with the first reference data may be:

comparing the pressure value detected by each pressure sensor carried in the first holding data with the pressure range of each pressure sensor corresponding to the first reference data respectively based on the serial number of the pressure sensor; and determining whether the pressure value detected by each pressure sensor falls into a corresponding pressure range or not, or determining whether the error is in a preset range, if so, determining that the pressure value and the error are matched, and further determining that the unlocking operation is initiated by the owner.

Based on the above two examples, detection of a handheld habit is added as a recognition condition when face recognition is turned on. When the user operates, the data of the pressure sensor and the reference data formed by the learning of the terminal are processed by an algorithm to be matched and compared, when the data are within a preset difference value range, the face recognition is accepted, and when the data are not within the range, the face recognition is refused, so that the situation that the owner holds the owner mobile terminal by hands through other people and steals owner information or fund through the face recognition is avoided, and the safety of face recognition unlocking is improved.

In addition, for simplicity of explanation, the above-described method embodiments are described as a series of acts or combinations, but it should be understood by those skilled in the art that the present invention is not limited by the order of acts or steps described, as some steps may be performed in other orders or simultaneously according to the present invention. Furthermore, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred and that no particular act is required to implement the invention.
