[0002] Currently, you can buy tickets offline at ticket windows or online through applications (APPs) to take public transportation such as trains and planes. However, when buying tickets, you only need to show your ID or provide your ID number, so it is not difficult to use someone else's identity information to buy tickets. In addition, when taking public transportation, you only need to show your ticket, so it is difficult for staff to distinguish whether the actual identity information of the person holding the ticket is the identity information recorded on the ticket.

[0003] For example, if a person smokes on a high-speed train, his information will be added to the high-speed train blacklist and he will not be allowed to board the high-speed train. However, it is easy for him to buy tickets and board the train by impersonating / borrowing other people's identity information, thus affecting social order.

[0046] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] See also Figure 1 An embodiment of the present invention provides an identity recognition system, which includes: a monitoring module, an analysis module, an ID card swiping platform and a central platform.

[0048] Among them, the monitoring module is used to collect facial images in the specified area.

[0049] The analysis module is used to analyze the identity of the person corresponding to the face image collected by the monitoring module.

[0050] The ID card swiping platform is used to collect identity information provided by people entering designated areas.

[0051] The central platform is used to display the analysis results of the analysis module.

[0052] The monitoring module can be a camera, and the analysis module and the central platform can be deployed in the same electronic device or in different electronic devices. The electronic device can be a mobile phone, a tablet computer, or a server. The ID card swiping platform can be a gate machine.

[0053] Combination Figure 1 The embodiment of the present invention also provides a method for identity recognition, see Figure 2 , this method can be applied to Figure 1 The electronic device in which the analysis module is deployed in the identity recognition system shown includes the following steps:

[0054] Step 201, obtaining a target face image collected in a specified area.

[0055] It can be understood that the target facial image can be any facial image collected in the specified area.

[0056] In one implementation, video information collected in a designated area and sent by a monitoring module may be received, and a target face image may be extracted from the video information.

[0057] For example, the analysis module may extract key frames from the received video according to a preset sampling frequency, and then identify and extract the target face image in each key frame.

[0058] In another implementation, when the camera in which the camera module is deployed is an intelligent camera capable of performing face recognition, the analysis module may receive a target face image collected in a designated area and sent by the monitoring module.

[0059] Step 202: If there is a facial image matching the target facial image in the designated information database, the actual identity information of the target person corresponding to the target facial image is determined to be: the identity information corresponding to the facial image matching the target facial image stored in the designated information database.

[0060] Exemplarily, the actual identity information in the embodiment of the present invention may be the ID number of the target person.

[0061] Step 203: Match the actual identity information of the target person with the identity information in the identity information record.

[0062] The identity information record includes the identity information provided by persons who enter the designated area within a preset time period.

[0063] For example, when the designated area is a train waiting room or an airplane waiting room, a person needs to verify the ticket at the gate when entering the waiting room. At this time, the gate can obtain the identity information corresponding to the ticket held by the person, and the identity information is the identity information provided by the person.

[0064] It is understandable that when the monitoring module is set inside the designated area and the ID card swiping platform is set at the entrance of the designated area, the ID card swiping platform first collects the identity information provided by the personnel, and the monitoring module then collects the facial image of the personnel entering the designated area, so the preset time period can be set as the time period between the moment when the monitoring module collects the facial image of the target person and the moment before that moment and the preset time distance from that moment. For example, the moment when the monitoring module collects the facial image of the target person is 10:00, the preset time distance is 1 minute, the moment before 10:00 and the moment 1 minute away from 10:00 is 9:59, and the preset time period is the time period between 9:59 and 10:00.

[0065] In the case where both the monitoring module and the ID card swiping platform are set at the entrance of the designated area, the moment when the monitoring module collects the facial image of the target person is before / after the moment when the ID card swiping platform collects the identity information provided by the target person, so the preset time period can be the time period between two moments of the preset time length from the moment when the monitoring module collects the facial image of the target person. For example, the moment when the monitoring module collects the facial image of the target person is 10:00, the preset time length is 1 minute, and the two moments 1 minute away from 10:00 are 9:59 and 10:01, and the preset time period is the time period between 9:59 and 10:01.

[0066] It is understandable that the same person may enter the designated area multiple times. In order to accurately identify whether the identity information provided by the person in the designated area when entering the designated area this time is his or her actual identity information, the identity information record can be set to include the identity information provided by the person who enters the designated area within a preset time period, so as to reduce the influence of the identity information provided by the person when entering the designated area before on the determination of whether the identity information provided by the person when entering the designated area this time is his or her actual identity information.

[0067] In addition, since the identity information collected by the ID card swiping platform within the preset time period is less, the computational complexity of matching the actual identity information corresponding to the collected facial image with the identity information collected by the ID card swiping platform within the preset time period can be reduced, thereby improving matching efficiency.

[0068] Step 204: If the actual identity information of the target person does not exist in the identity information record, it is determined that the identity information provided by the target person does not match the actual identity information.

[0069] It can be understood that the identity information record includes the identity information provided by persons entering the designated area within a preset time period. If the actual identity information of the target person does not exist in the identity record, it means that the identity information provided by the target person when entering the designated area does not match the actual identity information of the target person.

[0070] Optionally, if the actual identity information of the target person exists in the identity information record, it is determined that the identity information provided by the target person is consistent with the actual identity information.

[0071] Beneficial effects of the embodiments of the present invention: Since the embodiments of the present invention can determine that the actual identity information of the target person corresponding to the target face image is the identity information corresponding to the face image matching the target face image stored in the designated information database when there is a face image matching the target face image in the designated area in the designated information database. When the actual identity information of the target person does not exist in the identity information record, it means that the identity information provided by the target person when entering the designated area does not match the actual identity information. Therefore, the embodiments of the present invention can identify people who use / borrow other people's identity information to take public transportation.

[0072] Optionally, in the above step 202, there are two situations in which the designated information database is the overall information database or the second concerned person information database, so that the identity recognition method provided by the embodiment of the present invention includes the following two methods. Among them, the overall information database includes the identity information corresponding to each preset face image, and the second concerned person information database includes the identity information corresponding to the face image of each concerned person.

[0073] Method 1: See Figure 3 When the designated information database is the overall information database, the identity recognition method provided by the embodiment of the present invention includes:

[0074] Step 301, obtaining a target face image collected in a specified area.

[0075] Step 302, obtaining the actual identity information of the target person corresponding to the target face image from the overall information database.

[0076] Step 303, determine whether the first concerned person information database includes the actual identity information of the target person. If the first concerned person information database includes the actual identity information of the target person, execute step 304; if the first concerned person information database does not include the actual identity information of the target person, execute step 305.

[0077] The first concerned person information database includes the identity information of each concerned person.

[0078] Exemplarily, the concerned person may be a person corresponding to the person information recorded in the blacklist of the EMU train, or the concerned person may also be a person with a bad record. The embodiment of the present invention does not specifically limit the concerned person.

[0079] Step 304: determine that the target person is a person of concern.

[0080] Step 305: Determine that the target person is not a person of concern.

[0081] Step 306: Match the actual identity information of the target person with the identity information in the identity information record.

[0082] Step 307: If the target person is a person of interest and the identity information provided by the target person does not match the actual identity information, it is determined that the target person is a person of interest and has entered the designated area by impersonating another person.

[0083] Step 308: If the target person is a person of interest and the identity information provided by the target person is consistent with the actual identity information, the target person is determined to be a person of interest and enters the designated area.

[0084] Step 309: If the target person is not a concerned person and the identity information provided by the target person does not match the actual identity information, it is determined that the target person has entered the designated area by impersonating another person.

[0085] Step 310: If the target person is not a concerned person and the identity information provided by the target person is consistent with the actual identity information, it is determined that the identity information provided by the target person when entering the designated area is the actual identity information.

[0086] Method 2: See Figure 4 When the designated information database is the second concerned person information database, the identity recognition method provided by the embodiment of the present invention includes:

[0087] Step 401, obtaining a target face image collected in a specified area.

[0088] Step 402: If there is a facial image matching the target facial image in the second person of interest information database, the target person is determined to be a person of interest, and actual identity information corresponding to the facial image matching the target facial image is obtained from the second person of interest information database.

[0089] Step 403: If there is no facial image matching the target facial image in the second concerned person information database, it is determined that the target person is not a concerned person, and the actual identity information corresponding to the facial image matching the target facial image is obtained from the overall information database.

[0090] Step 404, matching the actual identity information of the target person with the identity information in the identity information record.

[0091] Step 405: If the target person is a person of interest and the identity information provided by the target person does not match the actual identity information, it is determined that the target person is a person of interest and has entered the designated area by impersonating another person.

[0092] Step 406: If the target person is a person of interest and the identity information provided by the target person is consistent with the actual identity information, the target person is determined to be a person of interest and enters the designated area.

[0093] Step 407: If the target person is not a concerned person and the identity information provided by the target person does not match the actual identity information, it is determined that the target person has entered the designated area by impersonating another person.

[0094] Step 408: If the target person is not a concerned person and the identity information provided by the target person is consistent with the actual identity information, it is determined that the identity information provided by the target person when entering the designated area is the actual identity information.

[0095] It can be seen that the embodiment of the present invention can determine whether the target person is a person of concern while determining the identity information of the target person. Therefore, the embodiment of the present invention can also play a role of real-time supervision, which is conducive to creating a social environment of integrity.

[0096] Optionally, the electronic device in the embodiment of the present invention may also send an alarm message to the central platform when the identity information provided by the target person does not match the actual identity information and / or the target person is a person of concern.

[0097] It can be understood that when the identity information provided by the target person does not match the actual identity information, the alarm information sent to the central platform may include the target person's identity information, the target person's target facial image, and prompt information that the target person has impersonated / borrowed other people's identity information to enter the designated area.

[0098] When the target person is a person of concern, the alarm information sent to the central platform may include the identity information of the target person, the target face image of the target person, and prompt information that the target person is a person of concern.

[0099] It can be seen that the embodiment of the present invention can use the camera in the specified area to collect facial images of people, and then analyze whether the specified area includes people of concern, and whether there are people who impersonate others' identity information in the specified area. Generally, there are cameras in waiting halls, so the embodiment of the present invention can use existing equipment to realize identity recognition, thereby improving resource utilization.
