Detailed Description
In recent years, with the rapid development of retail digitization, the retail scene under the line changes day by day, and most merchants use a self-service mode to receive cash. Meanwhile, China gradually enters an aging society, and the elderly need to pay certain learning cost in the face of changes. "aging" and "digitization" are keywords that today's society cannot circumvent. The learning ability of the elderly is slower and faster with age, while the digitization process is faster and faster.
It should be noted that, for high-frequency matters and service scenes related to the elderly, it is necessary to insist that the traditional service mode is parallel to the intelligent service innovation, so that the outstanding difficulty encountered by the elderly in the aspect of applying the intelligent technology is practically solved, and relevant deployment is performed on the related work of facilitating the elderly to apply the intelligent technology.

In the first scheme, the user identity is acquired through face recognition, the face information of the user needs to be collected in advance, the face information of all the users cannot be collected, and the problem of certain privacy safety in face collection is solved.
In the second prior art, when the self-service cashier starts, the user is forced to log in, and if a mobile phone number is input, and the self-service cashier device scans the member two-dimensional code of the mobile phone APP, the identity of the member user can be accurately identified.
In the second scheme, for users, especially for old users, user interaction is increased, so that the self-service cash-collecting process becomes complicated.
In order to improve at least one of the above technical problems of the present application, embodiments of the present application provide an identity recognition method and apparatus, an electronic device, and a storage medium, and the following describes technical solutions of the present application through possible implementation manners.
That is to say, the directional sound technology is used, the self-service cash registering process is optimized, the user interaction links are reduced or eliminated, the process is more intelligent and simplified, the learning cost of the user is reduced, the system requirements can be met, the whole self-service cash registering process is more in line with the habits of the user, and the non-sensory interaction experience is realized.
The defects existing in the above solutions are the results obtained after the inventor has practiced and studied carefully, so the discovery process of the above problems and the solutions proposed by the embodiments of the present application in the following description to the above problems should be the contributions made by the inventor in the invention process.

The embodiment of the present application provides an identification system 10, and the identification system 10 may include a cashier system 200, and the cashier system 200 included in the identification system 10 may interact with the electronic device 100.
The cashier system 200 is configured to send a directional sound wave signal to the coverage area, so that the electronic device 100 is configured to analyze the directional sound wave signal according to a preset rule to obtain first identification information of the cashier system 200 when receiving the directional sound wave signal sent by the cashier system 200, and the cashier system 200 is further configured to receive second identification information of the electronic device 100, establish communication connection with the electronic device 100, and perform identity recognition processing based on the second identification information.
Optionally, the specific structure of the cashier system 200 is not limited, and may be set according to the actual application requirements.
For example, in one alternative example, the cashier system 200 may comprise a directional sound emitter for sending a directional sound wave signal to the coverage area.
For another example, in another alternative example, the cashier system 200 may further comprise a self-service cashier device for sending order information to the electronic device 100, and a support device for fixedly connecting the directional sound emitter and the self-service cashier device. The directional sound emitter uses a directional sound technology, which is a technology for allowing sound to propagate in a certain direction. Compared with the traditional sound source, the directional sound source can control the propagation direction of the sound source and control the coverage range of sound waves, according to the acoustic theory, the sound waves heard by human ears belong to low-frequency sound waves, the sound is divergently propagated in all directions, the ultrasonic waves have directional propagation characteristics, and high-frequency signals with the frequency greater than 20KHz have directivity in the transmission process. The sound is made to travel in a narrow-band sound beam in a given direction, i.e. a "column" is sent, similar to the column emitted by a searchlight, so that only persons situated in the direction covered by the column can hear the sound. Briefly, the directional sound technology utilizes the directivity characteristics of ultrasonic waves, and through specific acoustic technologies and algorithms, audible sound can also be spread along a specified defense line.
In connection with fig. 1, the directional sound emitter may use a zone in front of the cashier system 200 as an identification zone ("fret" coverage) by directional sound technology, and the system will accurately identify the user entering the zone. The traditional sound propagation is similar to 'broadcasting', has no directivity and wide radiation area, and cannot limit a certain area.
Because the actual scene not only has one system unit, for example, a self-service cash register area of a supermarket has a plurality of self-service cash register devices, mutual interference among the system units is skillfully solved by adopting the directional sound wave, the recognition target is limited, and the target is limited by the sound wave range. The sound waves may also be non-directional if directed to only one system unit.
With reference to fig. 2, an area is located in front of the self-service cash register device, a directional sound emitter is located above the area, the sound emitter emits directional ultrasonic waves vertically downwards, the coverage area of the ultrasonic waves can just cover a user station in the area, and the self-service cash register device communicates with a mobile phone through the ultrasonic waves. Since the directional sound emitter emits ultrasonic waves, the user does not perceive it.
Where user a is the target user and user B (not in the directional sound coverage area) is the non-target user. That is, the coverage area is the area covered by the directional sound signal sent vertically downward by the directional sound emitter for accommodating a user.
Optionally, the specific manner in which the electronic device 100 sends the second identification information to the cashier system 200 is not limited, and may be set according to actual application requirements.
For example, in one alternative example, the electronic device 100 may send the second identification information to a server, which forwards the second identification information to the cashier system 200.
That is, the identification system 10 may further include a server for receiving the second identification information sent by the electronic device 100 and forwarding the second identification information to the cashier system 200.
It should be noted that, firstly, the information transmission efficiency of the sound wave is low, and a large amount of data needs to be quickly transmitted when the electronic device 100 interacts with the cash register system 200, so that the data is transmitted by sound in the present application to achieve mutual identity recognition between the electronic device 100 and the cash register system 200, and the problem to be solved is to realize mutual transmission of the identification information and connection.
Secondly, in the present application, the data transmission by sound is a one-way process, and the cashier system 200 may send directional sound to the electronic device 100, but the electronic device 100 cannot transmit information to the cashier system 200 by directional sound wave. The electronic device 100 emits sound without directivity, and the sound propagates in all directions and interferes with other system units.
Therefore, in the present application, the electronic device 100 may transmit the second identification information to the cashier system 200 through the server. In order to achieve mutual identity recognition in the prior art, active operation of a user is needed, experience is poor, and according to the scheme, mutual identity recognition is achieved through sound wave communication, then service processing is conducted through a network, active operation of the user is reduced through a passive mode, partial interaction noninductivity is achieved, and user checkout efficiency is improved. That is to say, the connection can be generated through sound, the connection process is passive, manual intervention is not needed, and service data interaction is carried out through the network, so that the service function is realized.
With reference to fig. 3, the self-service cash register device sends out information with its own identifier through the directional sound emitter, and when the user holds the mobile phone to enter the ultrasonic coverage area, the mobile phone receives ultrasonic waves containing the self-service cash register device identifier (first identifier information), and then obtains the self-service cash register device identifier through sound wave decryption. At this time, the mobile phone sends the user identifier (second identification information) and the self-service cash register device identifier to the server, then the server sends the user identifier to the designated self-service cash register device, at this time, the identification of the member user identity by the self-service cash register device is completed, and all operations in the self-service cash register device can be related to the current user information, such as personalized marketing and the like for the user. When the user settles in the self-service cash register device, the self-service cash register device sends order information to the server, and the server sends the order information to the bound user mobile phone according to the binding relationship between the current self-service cash register device and the mobile phone. The user does not need to operate, order information is automatically displayed on the mobile phone, and only payment is needed, so that an automatic two-way communication link between the self-service cash register and the mobile phone is realized, user participation is reduced, and the user operation flow is simplified.
For the electronic device 100, it should be noted that the electronic device 100 may include, but is not limited to, a mobile phone, a tablet computer, a wearable device, an in-vehicle device, an Augmented Reality (AR)/Virtual Reality (VR) device, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a Personal Digital Assistant (PDA), and the like, and the specific type of the electronic device 100 is not limited in this embodiment.

The controller may be, among other things, a neural center and a command center of the electronic device 100. The controller can generate an operation control signal according to the instruction operation code and the timing signal to complete the control of instruction fetching and instruction execution.
A memory may also be provided in processor 110 for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may hold instructions or data that have just been used or recycled by the processor 110. If the processor 110 needs to reuse the instruction or data, it can be called directly from memory. Avoiding repeated accesses reduces the latency of the processor 110, thereby increasing the efficiency of the system.
The electronic device 100 may implement audio functions via the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the application processor 110, and the like. Such as transmitting, receiving acoustic signals, etc.
The audio module 170 is used to convert digital audio information into an analog audio signal output and also to convert an analog audio input into a digital audio signal. The audio module 170 may also be used to encode and decode audio signals. In some embodiments, the audio module 170 may be disposed in the processor 110, or some functional modules of the audio module 170 may be disposed in the processor 110.
The speaker 170A, also called a "horn", is used to convert the audio electrical signal into an acoustic signal. Electronic device 100 may send acoustic signals through speaker 170A.
The receiver 170B, also called "earpiece", is used to convert the electrical audio signal into an acoustic signal. When the electronic apparatus 100 receives a call or voice information, it can receive voice by placing the receiver 170B close to the ear of the person.
The microphone 170C, also referred to as a "microphone," is used to convert sound signals into electrical signals. When making a call or transmitting voice information, the user can input a voice signal to the microphone 170C by speaking the user's mouth near the microphone 170C. The electronic device 100 may be provided with at least one microphone 170C. In other embodiments, the electronic device 100 may be provided with two microphones 170C to achieve a noise reduction function in addition to collecting sound signals. In other embodiments, the electronic device 100 may further include three, four or more microphones 170C to collect sound signals, reduce noise, identify sound sources, receive directional sound signals, and so on.
Fig. 5 shows one of flowcharts of an identification method provided in the embodiment of the present application, where the method is applicable to the electronic device 100 shown in fig. 4 and is executed by the electronic device 100 in fig. 4. It should be understood that, in other embodiments, the order of some steps in the identification method of this embodiment may be interchanged according to actual needs, or some steps may be omitted or deleted. The flow of the identification method shown in fig. 5 is described in detail below.
Step S510, in a case that the directional acoustic wave signal sent by the cashier system 200 is received, analyzing the directional acoustic wave signal according to a preset rule to obtain first identification information of the cashier system 200.
The cashier system 200 is used, among other things, to send directional acoustic signals to the coverage area.
Step S520, sending the second identification information of the electronic device 100 to the cashier system 200 to establish a communication connection with the cashier system 200, and the cashier system 200 performing an identity recognition process based on the second identification information.

For step S510, it should be noted that the specific way of performing the parsing process is not limited, and may be set according to the actual application requirement. For example, in an alternative example, step S510 may include the following sub-steps:

In detail, the audio may be decrypted according to the principle of sound wave communication. The directional sound transmitter encodes the data with a single frequency sound signal, plays the single frequency sound, and the receiver recognizes the frequency after receiving the sound and then decodes the data according to the frequency. Such as: a sine wave of 1500HZ corresponds to a number 1, a sine wave of 1600HZ corresponds to a number 2, and a sine wave of 1700HZ corresponds to a number 3. The string 3123 corresponds to 4 segments of sine waves, each of which is specified to last 100ms (i.e., the predetermined duration may be 100ms), and 3123 corresponds to a 400 ms segment of sound. The receiving party records the sound, decomposes the received sound to obtain four sound wave segments with preset time duration, the frequencies of the sound wave segments are 1700HZ, 1500HZ, 1600HZ and 1700HZ respectively, then the codebook is searched, and the decoded number is 3123.
