Description

Technical Field

[0001] The present invention belongs to the field of information security technology, and specifically relates to a method for preventing leakage of sensitive personal information through 5G new calls. Background Art

[0002] Currently, mobile APPs need to authenticate sensitive personal information in a large number of business scenarios, such as requiring users to take photos of their ID cards, upload the front and back of their bank cards, and collect video information for liveness examinations. Figure 1 As shown, these sensitive personal information will be transmitted to the cloud APP server through the mobile APP, and then transferred to the third-party authentication server for authentication.

[0003] However, some apps may save sensitive personal information of users and even original images, videos, etc. for various purposes. External hackers may exploit system vulnerabilities to steal the APP database, and internal employees may exploit management vulnerabilities to steal the APP database and sell it, resulting in user information being leaked, and even causing fraud or illegal bank card account opening and other malicious problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to address the deficiencies of the above-mentioned prior art and provide a method for preventing the leakage of sensitive personal information through 5G new calls. By directly entering a highly trusted operator authentication server through 5G new calls, it can be ensured that all sensitive information does not flow into the APP, and with the user's permission, it can be judged whether the user behavior is abnormal based on the user's dynamic data as a basis for further judgment. In the end, the APP only needs to obtain the authentication result to ensure the normal operation of subsequent business.

[0005] In order to achieve the above technical objectives, the technical solution adopted by the present invention is:

[0006] A system for preventing leakage of sensitive personal information through 5G new calls, including a 5G mobile phone, an APP server, and a 5G new call server, an authentication server, and an information library within the operator;

[0007] Among them, authentication requests and results are transmitted between 5G mobile phones, APP servers, and authentication servers;

[0008] Authentication of users’ sensitive personal information is carried out between 5G mobile phones, 5G new call servers, authentication servers and information databases.

[0009] To optimize the above technical solutions, the specific measures taken also include:

[0010] The above-mentioned 5G mobile phone includes a completely isolated business APP and a 5G new call module;

[0011] The business APP is used to initiate authentication for the user, requiring the user to enter a mobile phone number, and passing the mobile phone number provided by the user to the APP server for subsequent authentication; and receiving and displaying the authentication result returned by the APP server after the authentication is completed;

[0012] The 5G new call module is used to provide personal sensitive information through video shooting as required after receiving an incoming call request from the 5G new call server, and to send the current geographic location coordinates and other auxiliary certification documents through the data channel based on the audio and video call.

[0013] The above-mentioned APP server is used to receive the user's mobile phone number sent from the business APP, and send it to the authentication interface located in the authentication server within the operator. After the authentication is completed, it receives the desensitized authentication result fed back by the authentication interface and sends it to the business APP.

[0014] The above-mentioned 5G new call server is used to initiate audio and video calls to the 5G new call module.

[0015] The above-mentioned authentication server includes an authentication interface, a video authentication module and a geographic location processing module;

[0016] Among them, the authentication interface is used to interact with the APP server for authentication requests and results;

[0017] The video authentication module is used to send a prompt video to the 5G new call module on the basis of the audio and video call, receive the user's personal sensitive information video sent by the 5G new call module, extract the corresponding information and compare it with the information in the information database to obtain the video authentication result, and send the authentication result to the 5G new call module via video; and feed back the authentication result to the authentication interface;

[0018] The geographic location processing module is used to send a geographic location request video to the 5G new call module based on the audio and video call, receive the geographic location sent by the 5G new call module through the DC channel, and analyze the user's geographic location history in the information database to determine whether the user has abnormal behavior, and feed back the geographic location authentication result to the authentication interface.

[0019] The above-mentioned location processing module analyzes the user's location history in the information database and determines that the user behavior is abnormal when the following situations exist:

[0020] The computer is suddenly turned on in a different location after being shut down for a long time;

[0021] The user's historical location track changes too frequently and is not a frequently visited location, or the user frequently visits certain sensitive areas;

[0022] The base station where the user's mobile phone is currently registered is too remote and is not a frequently visited location.

[0023] The above-mentioned information base includes a database and interface for various information of users;

[0024] The information includes name, ID number, bank card number, roaming trajectory, user facial video, and user geographic location;

[0025] The name and ID number are stored within the operator;

[0026] The bank card number is stored in a bank outside the operator;

[0027] The roaming track is stored within the operator if the user number is under the operator, and is stored outside the operator if the user number is under another operator;

[0028] The user's facial video and user's geographic location are used for dynamic comparison and analysis.

[0029] A method for preventing leakage of sensitive personal information through 5G new calls, the method comprising the following steps:

[0030] Step 1: The 5G mobile phone initiates authentication of the user through the service APP, requiring the user to enter the mobile phone number, and passes the mobile phone number provided by the user to the APP server for subsequent authentication;

[0031] Step 2: The APP server receives the user's mobile phone number sent from the service APP and sends it to the authentication interface in the authentication server located within the operator;

[0032] Step 3: The 5G new call server initiates an audio and video call to the 5G new call module of the 5G mobile phone;

[0033] Step 4: Based on the audio and video call, the authentication server sends a prompt video to the 5G new call module, receives the user's personal sensitive information video sent by the 5G new call module, extracts the corresponding information and compares it with the information in the information database to obtain the video authentication result, and sends the authentication result to the 5G new call module via video; and feeds back the authentication result to the authentication interface; sends the geographic location requirement video to the 5G new call module, receives the geographic location sent by the 5G new call module through the DC channel, and analyzes it with the user's geographic location history in the information database to determine whether the user has abnormal behavior, and feeds back the geographic location authentication result to the authentication interface;

[0034] Step 5: The authentication interface returns the authentication result to the APP server. The 5G mobile phone receives and displays the authentication result returned by the APP server through the business APP.

[0035] The above step 4 specifically includes:

[0036] Based on the audio and video call, the authentication server sends the video authentication instructions and required materials to the 5G new call module;

[0037] The 5G new call module uses a camera to capture the user's authentication information in real time, including ID card, bank card, personal facial information, and liveness detection;

[0038] The data information is transmitted to the video authentication module of the authentication server through the video. The video authentication module obtains the name and ID number on the ID card and the bank card number on the bank card through OCR, and cuts out the user's video through video recognition;

[0039] The 5G new call module transmits the data to the internal basic data server and bank server according to the preset address for name, ID card, facial information comparison and bank card authentication;

[0040] Generate a result video based on the authentication result, including the customer's name, ID number, and photo, and let the user confirm it by voice;

[0041] After the user confirms through voice, the video authentication module returns the authentication result to the authentication interface.

[0042] The above step 4 specifically includes:

[0043] The video authentication module initiates a geolocation security scan prompt video to the 5G new call module of the user's 5G mobile phone, asking the user to send the current coordinates and authorize the historical trajectory;

[0044] The 5G new call module obtains the current geographic location through the GPS module and sends it to the geographic location processing module through the data channel;

[0045] The geographic location processing module retrieves the user's historical trajectory from the information database, and then verifies the user's geographic location based on the information in the information database. Based on the historical information, it determines whether the user has any abnormalities and returns the authentication result to the authentication interface.

[0046] The present invention has the following beneficial effects:

[0047] The present invention completely removes the authentication process of the user's sensitive personal information from the APP, and instead transmits it through the operator's new 5G call; the operator intercepts and identifies the corresponding information from the video stream, and identifies whether the face has obvious external injuries such as beatings and scratches, and then authenticates through internal and external data; the operator obtains the user's current coordinates through the data channel in the new 5G call, and makes security judgments based on historical trajectories; the APP can only obtain desensitized data and encrypted complete data, and the complete data can only be obtained by the relevant department from the operator by decrypting the data when necessary.

[0052] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0053] Although the steps in the present invention are arranged with numbers, they are not used to limit the order of the steps. Unless the order of the steps is clearly stated or the execution of a certain step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" used in this article involves and covers any and all possible combinations of one or more of the associated listed items.

[0054] like Figure 2 As shown, a system for preventing leakage of sensitive personal information through 5G new calls of the present invention mainly includes a 5G mobile phone, an APP server, a 5G new call server, an authentication server and an information library. The thin lines represent authentication requests and results, and the thick lines represent authentication data. It can be seen that the user's sensitive data does not flow into the APP server, so there is no leakage problem mentioned above.

[0055] Specifically: sensitive personal information refers to personal information that, once leaked or illegally used, may easily lead to infringement of a natural person's personal dignity or endanger personal or property safety, including information such as biometrics, religious beliefs, specific identities, medical health, financial accounts, whereabouts, and personal information of minors under the age of fourteen.

[0056] The 5G new call is a new generation of call product launched based on the 5G network. The present invention provides a series of innovative call enhancement services and innovative applications based on the ultra-clear voice call, video call service and related value-added services of the 5G network.

[0057] In the embodiment, Figure 3 As shown:

[0058] (1) There are mainly two parts on the mobile phone: the APP and the 5G new call part. The two are completely isolated, preventing the business APP from obtaining sensitive user information.

[0059] When business apps require users to authenticate sensitive information due to various business requirements, they only require users to provide their mobile phone numbers, which are then passed to the app server for subsequent authentication. After the authentication is completed, the app server notifies the app of the authentication result and displays it to the end user.

[0060] The 5G new call module can send files and geographic location coordinates through the data channel on the basis of the current audio and video calls. After receiving the call request from the 5G new call server, it provides private information such as ID card, bank card, personal face, etc. through video shooting as required. If the user further agrees to provide additional information later, the current geographic location coordinates and other auxiliary certification documents can also be sent through the data channel.

[0061] The Data Channel (DC) is a new IMS data service bearer channel, which improves the data service expansion capability of traditional call scenarios, and combines with terminals upgraded with native baseband chips and native upper-layer application SDKs to achieve real-time interaction of various types of data from the cloud to users and between users. It can transmit files, locations, forms, AR / VR and other data, and realize synchronous presentation of audio and video calls and data channel media on the terminal.

[0062] (2) The APP server first receives the user's mobile phone number from the APP and sends it to the authentication interface in the authentication server located within the operator. After the authentication is completed, the authentication interface sends the de-sensitized authentication result to the APP server.

[0063] (3) The operator’s internal structure includes three parts: 5G new call server, authentication server and information database:

[0064] (3.1) 5G new call server load receives user's video and geographic location coordinates

[0065] (3.2) The authentication server is a functional module used for authentication processing

[0066] ①The authentication interface is responsible for interacting with the APP server

[0067] ②Video authentication responsible

[0068] Play prompts to the end customer, asking them to take photos of their ID card, bank card, personal face, etc.

[0069] Extract the corresponding information and compare it with the information in the database;

[0070] Identify whether there are obvious injuries on the face such as beatings, scratches, etc.;

[0071] Display the authentication results to the end user via video;

[0072] Notify the authentication interface of the authentication result;

[0073] ③ Geographic location processing is responsible for receiving the geographic location sent by the user through the DC channel, and analyzing it with the user's geographic location history in the information database to determine whether the user has abnormal behavior, and notify the result to the authentication request result. Abnormal situations are mainly used to determine whether the user's behavior is abducted, information stolen, deceived into a pyramid scheme, etc. The basis includes but is not limited to:

[0074] The computer is suddenly turned on in a different location after being shut down for a long time;

[0075] The user's historical location track changes too frequently and is not a frequently visited location, or the user frequently visits certain sensitive areas;

[0076] The location of the base station currently registered by the user's mobile phone is too remote and is not a frequently visited location;

[0077] (3.3) The information library is a database and interface that contains various information about users. For ease of description, it is drawn as one, but in fact there are multiple ones.

[0078] If divided by location, some data such as name and ID number can be stored within the operator; some data such as bank card number can be stored in banks outside the operator; some data such as roaming track can be stored within the operator if the user number is under the name of the operator, and stored in external operators if it is other operators.

[0079] According to the function, some of the information is static, such as ID card number, bank card number, etc., which can be directly compared; some of the information is dynamic, such as user facial video, user geographic location, etc., which need to be dynamically compared and analyzed.

[0080] The method of preventing leakage of sensitive personal information through 5G new calls of the present invention comprises the following steps:

[0081] Step 1: The 5G mobile phone initiates authentication of the user through the service APP, requiring the user to enter the mobile phone number, and passes the mobile phone number provided by the user to the APP server for subsequent authentication;

[0082] Step 2: The APP server receives the user's mobile phone number sent from the service APP and sends it to the authentication interface in the authentication server located within the operator;

[0083] Step 3: The 5G new call server initiates an audio and video call to the 5G new call module of the 5G mobile phone;

[0084] Step 4: Based on the audio and video call, the authentication server sends a prompt video to the 5G new call module, receives the user's personal sensitive information video sent by the 5G new call module, extracts the corresponding information and compares it with the information in the information database to obtain the video authentication result, and sends the authentication result to the 5G new call module via video; and feeds back the authentication result to the authentication interface; sends the geographic location requirement video to the 5G new call module, receives the geographic location sent by the 5G new call module through the DC channel, and analyzes it with the user's geographic location history in the information database to determine whether the user has abnormal behavior, and feeds back the geographic location authentication result to the authentication interface;

[0085] Step 5: The authentication interface returns the authentication result to the APP server. The 5G mobile phone receives and displays the authentication result returned by the APP server through the business APP.

[0086] In the embodiment, step 4 specifically includes:

[0087] Based on the audio and video call, the authentication server sends the video authentication instructions and required materials to the 5G new call module;

[0088] The 5G new call module uses a camera to capture the user's authentication information in real time, including ID card, bank card, personal facial information, and liveness detection;

[0089] The data information is transmitted to the video authentication module of the authentication server through the video. The video authentication module obtains the name and ID number on the ID card and the bank card number on the bank card through OCR, and cuts out the user's video through video recognition;

[0090] The 5G new call module transmits the data to the internal basic data server and bank server according to the preset address for name, ID card, facial information comparison and bank card authentication;

[0091] Generate a result video based on the authentication result, including the customer's name, ID number, and photo, and let the user confirm it by voice;

[0092] After the user confirms through voice, the video authentication module returns the authentication result to the authentication interface.

[0093] In the embodiment, step 4 specifically further includes:

[0094] The video authentication module initiates a geolocation security scan prompt video to the 5G new call module of the user's 5G mobile phone, asking the user to send the current coordinates and authorize the historical trajectory;

[0095] The 5G new call module obtains the current geographic location through the GPS module and sends it to the geographic location processing module through the data channel;

[0096] The geographic location processing module retrieves the user's historical trajectory from the information database, and then verifies the user's geographic location based on the information in the information database. Based on the historical information, it determines whether the user has any abnormalities and returns the authentication result to the authentication interface.

[0097] like Figure 4 As shown, the method of the present invention for preventing leakage of sensitive personal information through 5G new calls is specifically implemented as follows:

[0098] S1. The business APP initiates authentication for the user, requiring the user to enter their mobile phone number, and then sends the relevant information to the APP server;

[0099] S2. The APP server forwards the basic information to the authentication interface of the operator's authentication server. The authentication interface checks whether the APP manufacturer has a contract with the operator. If yes, it proceeds to step 3. If not, it directly returns an error to the APP server.

[0100] S3. Initiate a call, the called party's mobile phone number is provided by the user, and is sent to the 5G new call server.

[0101] S4.5G new call server calls mobile phone;

[0102] S5. User connected;

[0103] S6. The video authentication server plays the video authentication instructions and the materials that need to be prepared to the user;

[0104] The S7.5G New Call APP uses the camera to take real-time photos of the information that the user needs to authenticate, including but not limited to ID cards, bank cards, personal facial information, liveness detection, and identification of whether the face has obvious injuries such as beatings and scratches;

[0105] S8. These sensitive information are transmitted to the video authentication module through the video. The video authentication module obtains the name and ID number on the ID card and the bank card number on the bank card through OCR, and cuts out the user's video through video recognition;

[0106] S9. The user transmits this information to the preset address:

[0107] (1) Internal basic data server: used for name, ID card, and facial information comparison;

[0108] (2) Bank server: used for bank card authentication;

[0109] S10. Generate a result video based on the authentication result, including the customer's name, ID number, photo, whether the authentication is passed or not, and allow the user to confirm by voice;

[0110] S11. The user confirms by voice;

[0111] S12. The video authentication module returns the authentication result to the authentication interface;

[0112] S13. At the same time, the video authentication module initiates a geographic location security scan prompt to the user, asking the user to send the current coordinates and authorize the historical trajectory;

[0113] S14.5G new call module obtains the current geographic location from the GPS module and sends it to the geographic location processing server through the data channel;

[0114] S15. The location processing module retrieves the user's historical trajectory from the information database, and then checks the user's location, and determines whether the user has any abnormality according to the previously described situation;

[0115] S16. The geographic location processing module returns the processing result to the authentication interface;

[0116] S17. The authentication interface returns the authentication result to the APP server after desensitizing the plain text. For example, Zhang San is desensitized to Zhang*San. The complete information is encrypted and processed with base64 before being returned to the APP server for storage. In the future, if the user commits illegal acts, the relevant government departments can apply to the operator for destruction based on the encrypted data;

[0117] S18. The APP server returns the authentication result to the APP module on the mobile phone.

[0118] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0119] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
