Description

Technical Field

[0001] Embodiments of the present disclosure relate to the field of identity authentication, and in particular, to a method and apparatus for real-person identity authentication based on a social platform, and a computer-readable storage medium storing a computer program. Background Art

[0002] The main purpose of real-person authentication is to confirm whether the user is a real human individual and to prevent robots, virtual characters or other non-human entities from impersonating users. It focuses on identifying the authenticity behind the identity rather than just the legitimacy of the identity.

[0003] With the popularity of social media platforms, the problem of false identities has become increasingly prominent. Traditional identity authentication methods, such as simple profile picture verification, facial recognition, or photo uploads, pose significant security risks. Users can forge their identities by uploading photos or videos of others, making authentication systems easily circumvented. Therefore, a more rigorous and reliable real-person authentication method is needed. Summary of the Invention

[0004] The embodiments described herein provide a method, apparatus, and computer-readable storage medium storing a computer program for real-person identity authentication based on social platforms. By combining user behavioral data with specified 3D gestures, these methods can more accurately identify real users and prevent fake accounts and bots from bypassing authentication through static methods. The multimodal technology, combining motion recognition and face detection, enhances the security and effectiveness of the authentication process.

[0005] According to a first aspect of the present disclosure, a real-person identity authentication method based on a social platform is provided, including: obtaining behavioral data of users on the social platform, and guiding the users to enter a real-person authentication interface based on the behavioral data; guiding the users to complete specified actions within a specific time on the real-person authentication interface, capturing the user's authentication image in real time, and specifying the actions as continuous actions including stereo gestures; performing action recognition and face detection on the authentication image based on a multimodal recognition model to obtain an authentication result; and performing social empowerment on the authenticated user on the social platform based on the authentication result, the social empowerment including real-person authentication identification, priority recommendation and extended social function permissions.

[0006] In some embodiments of the present disclosure, obtaining the user's behavioral data on the social platform and guiding the user to enter the real-person authentication interface based on the behavioral data includes: guiding the user to upload an avatar and enter the real-person authentication interface when the user registers an account; continuously monitoring the user's behavioral data on the social platform, the behavioral data including login device, login frequency, interaction records and content, analyzing the user's activity, interaction quality, account security based on the behavioral data, and evaluating whether identity authentication is required; guiding the user to enter the real-person authentication interface when abnormalities in the unauthenticated user's device or abnormal social behavior are detected.

[0007] In some embodiments of the present disclosure, a user is guided to complete a specified action within a specific time on a real-person authentication interface, and the user's authentication image is captured in real time.

[0008] In some embodiments of the present disclosure, action recognition and face detection are performed on the authentication image based on a multimodal recognition model, and obtaining the authentication result includes: extracting the user's facial features in the authentication image based on the face recognition model, performing face recognition verification by comparing the user's facial features with pre-stored user images, and obtaining the facial recognition result; obtaining the key point position and motion trajectory of the user in the authentication image through the action recognition model, judging whether the user has completed the specified action, and obtaining the action recognition result; fusing the action recognition result with the face recognition result to obtain the authentication result.

[0009] In some embodiments of the present disclosure, the motion recognition result is integrated with the facial recognition result to obtain an authentication result including: if both the motion recognition result and the facial recognition result pass, the authentication result is passed; if either one of the motion recognition result and the facial recognition result fails or both fail, the authentication fails.

[0010] In some embodiments of the present disclosure, action recognition and face detection are performed on the authentication image based on a multimodal recognition model, and obtaining the authentication result also includes: using computer vision technology to analyze the lighting conditions and background of the user's environment to determine whether the user's environment is a real environment; judging whether the user's expression changes are consistent with the normal expression changes of a real person through a facial expression recognition model; and if the authenticity of the authentication cannot be confirmed during the multimodal recognition process, it is marked as pending manual review.

[0011] In some embodiments of the present disclosure, social empowerment is performed on the social platform for the authenticated user based on the authentication result.

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work also fall within the scope of protection of the present disclosure.

[0021] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present disclosure belongs. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the specification and the relevant art, and will not be interpreted in an idealized or overly formal manner unless otherwise explicitly defined herein.

[0022] In order to enhance the user experience and trust mechanism of social platforms, the embodiments of the present disclosure provide a real-person identity authentication method and device based on social platforms, which intelligently guides users to complete dynamic verification, combines behavioral data with multi-dimensional recognition technology, improves the security and reliability of authentication, and provides social empowerment for authenticated users to enhance the user's social interaction experience.

[0023] Figure 1 FIG. 1 is an exemplary flow chart of a real person identity authentication method 100 based on a social platform according to an embodiment of the present disclosure. Figure 1 As shown, in Figure 1 In block S102 , the user's behavior data on the social platform is obtained, and the user is guided to enter the real person authentication interface based on the behavior data.

[0024] When registering an account, users are prompted to upload a profile picture and enter the real-person verification interface. For example, when editing their profile on their homepage, the system will prompt them to upload a real profile picture. While uploading their profile picture, users are reminded that they need to complete real-person verification before editing their profile, ensuring the authenticity of their information. When users attempt to contact others, if they haven't completed verification, they will be prompted to do so, or unlocking certain permissions will require verification.

[0025] In some embodiments of the present disclosure, the user's behavioral data on the social platform is continuously monitored, including login device, login frequency, interaction records and content, etc. For example, user behavior data includes: login device, login frequency, active time period, content publishing behavior (such as text, pictures, videos, etc.), comments and interaction records, etc.; user's friends or followers' interactions (such as likes, comments, shares, etc.); user's social network activities (such as group participation, discussion topics, private message exchanges, etc.); account security behavior, such as password modification, login device change, etc. Based on the user's behavioral data, the user's activity, interaction quality, account security and other dimensions are analyzed to assess whether they need identity authentication.

[0026] Unauthenticated users' social functions will be restricted (e.g., they cannot send messages to unauthenticated users). If an unauthenticated user triggers a risk control rule, they will need to undergo real-person authentication, otherwise they will not be able to continue using the chat function. If an unauthenticated user's device or social behavior is detected to be abnormal, the user will be guided to the real-person authentication interface. Alternatively, the user will be prompted to authenticate their identity through push notifications, pop-up notifications, etc. For example, "Unusual behavior has been detected in your account. Please complete identity verification to ensure account security."

[0027] For example, if the device a user logs in to is different from their usual device, they frequently change devices to log in, they log in to multiple accounts with the same device in a short period of time, or the device information used does not match the historical records, it will be judged as risky behavior and real-person authentication will be required. If the user's social behavior is abnormal, such as chat content that violates regulations, involves fraud, sensitive information, malicious harassment and other inappropriate remarks, or content that violates platform regulations, it will be considered that there is an identity risk. Or, if there are frequent and invalid interactions (such as adding a large number of friends in a short period of time, sending homogeneous messages but the other party does not respond), this may indicate that the user is at risk of guiding others to click on links or engaging in fraudulent behavior. If the user's interaction method frequently includes diversion, promotion of external links and other behaviors, the system will determine that the user may be engaging in improper behavior and requires real-person authentication.

[0028] Then in step S104, the user is guided to complete a designated action within a specific time on the real person authentication interface, and the user's authentication image is captured in real time. The designated action is a continuous action including a three-dimensional gesture.

[0029] First, a designated three-dimensional gesture is randomly generated on the real-person authentication interface, and the actions that the user needs to complete and the time limit are displayed in real time. During the authentication process, continuous actions such as cat hand gestures, finger rotation, palms up or down, and arm raising are randomly generated. The authentication interface displays clear step-by-step instructions, "Please follow the instructions on the screen to complete the gestures to verify your identity" and "Please complete the authentication action within 30 seconds." Then, in real time, the user is dynamically guided to perform an eye gaze test within a preset time, completing the continuous designated actions, and the user's authentication image is captured by the camera. The authentication image includes the user's facial features and hand movements. For example, the user is asked to look at a specific target point on the screen, or the user's eyes are asked to move along with the target point that appears on the screen.

[0030] Traditional authentication gestures, such as the scissor hand gesture, are easily faked through screen captures or photos. However, gestures like the cat hand gesture and finger rotation gesture are more complex and require three-dimensional positioning, making them difficult to fake. This designated gesture effectively prevents fraudulent attempts such as staged photos and screenshots because the gesture is dynamic and real-time, making it difficult to forge.

[0031] Then in step S106, action recognition and face detection are performed on the authentication image based on the multimodal recognition model to obtain an authentication result.

[0032] First, the system identifies whether there is a face in the photo. If the submitted profile picture or authentication photo does not contain a face, the system will prompt the user "No face detected" and require them to recapture the authentication image. The system then further determines whether the uploaded profile picture and the authentication photo are the same person, and whether there are any gender or other identity mismatch issues. The facial recognition model extracts the user's facial features from the authentication image, identifying key facial features (such as eyes, nose, and mouth) and their locations. Facial recognition verification is performed by comparing the user's facial features with pre-stored user images to obtain the facial recognition result.

[0033] The action recognition model uses the positions and motion trajectories of the user's key points in the authentication image to determine whether the user has completed the designated action and obtain the action recognition result. For example, the positions and motion trajectories of the user's key points (such as finger joints, elbows, shoulders, and eyes) are extracted. By comparing the dynamic changes of these key points, it is determined whether the user has completed the designated gesture or action.

[0034] Finally, the motion recognition results are combined with the facial recognition results to produce the authentication result. If both the motion recognition and facial recognition results pass, the authentication result passes; if either or both fail, the authentication fails. This fusion can be achieved through simple logical judgment (such as a conditional "AND" connection). Alternatively, a more complex decision-making mechanism can be used to further assess the credibility of the authentication result through comprehensive weighting.

[0035] Furthermore, computer vision technology is used to analyze the lighting and background of the user's environment to determine whether the user's environment is real. Poor lighting conditions or abnormal backgrounds may result in poor image quality, affecting the accuracy of authentication. Therefore, the system needs to check the environment to ensure that the image quality during the authentication process meets the expected standards. The facial expression recognition model analyzes the user's facial expressions to determine whether the user has normal facial expressions. This includes identifying common facial expressions such as smiling, blinking, and mouth movements. If, during the multimodal recognition process, the system finds that it cannot confirm the authenticity of the authentication, or if some important information (such as motion recognition or facial recognition) cannot be accurately judged, the system will mark the authentication for manual review. This usually occurs when the system detects image quality issues (such as poor lighting, missing expression) or abnormal behavior (such as incomplete action). The system automatically forwards the authentication request to a manual reviewer for further confirmation to ensure the accuracy and security of identity authentication.

[0036] Finally, in step S108, based on the authentication result, the authenticated user is given social empowerment on the social platform, which includes real-person authentication identification, priority recommendation, and extended social function permissions.

[0037] In some embodiments of the present disclosure, if authentication is successful, the social platform assigns an authentication tag to the authenticated user, indicating that the user has passed real-person identity verification. This tag not only represents the credibility of the user's identity but may also serve as a symbol of preferential treatment by the platform, enhancing the user's social status. If authentication fails, the user will be re-entered into the real-person authentication interface.

[0038] Users who pass the authentication will receive a "real person authentication" label and will enjoy the permissions associated with the label. Certified users will be given priority recommendations and social rewards on social homepages, and their social function permissions will be increased. Social empowerment includes but is not limited to authentication level identification: different authentication identifications (such as general authentication, advanced authentication, etc.) are assigned to users according to the level of authentication. The platform can further encourage users to conduct real person authentication and increase their participation through incentive mechanisms such as points, exclusive badges, and titles. Priority recommendation: Certified users will be given priority recommendation to other platform users to enhance the credibility and influence of their social interactions. Expanded interaction permissions: Certified users can obtain more social function permissions, such as participating in more interactions, obtaining higher interaction priority, etc., to enhance the user's activity and influence on the platform.

[0039] Continuously collect authentication behavior and social interaction data of authenticated users, and dynamically adjust their authentication tags and social permissions. The validity of authentication may be adjusted over time and with changes in behavior. For example, if the platform detects abnormal behavior of an authenticated user, it may temporarily revoke their authentication identity or require re-authentication with a real person. To increase the system's protection capabilities, the system can design a periodic verification mechanism that requires users to perform action verification regularly, especially when there are high-risk operations (such as changing account settings, large transactions, etc.).

[0040] In some embodiments of the present disclosure, users can also invite others to perform real-person authentication. Based on the user's authentication invitation, the invited user is guided to perform real-person authentication. The authentication invitation entrance is set in the private chat interface, chat settings page, etc. Users can click to invite others for authentication. Through real-person authentication, the authenticity of the other party's profile picture is ensured, reducing the risk of encountering fake users. Authenticated users have relatively higher activity and response rates, the social experience will be smoother, and the enthusiasm for subsequent social interactions will be increased.

[0041] If the invited user completes the authentication, he / she will obtain a real person authentication mark, system rewards and priority recommendation matching. If the authentication fails, a social suggestion prompt will be sent to the authentication inviting user or the user suspected of fraud will be blacklisted.

[0042] For example, after user A invites user B to authenticate, if the authentication is successful, a "real person green V" authentication mark will be added to user B's personal information card. If the authentication fails, user B will not receive the green V mark, the authentication status will remain unchanged, and the system will prompt re-authentication. User A can check user B's authentication status in the private chat interface. If user B has not authenticated for a long time or has not passed the authentication, the platform will give user A certain prompts in the social suggestions, such as: "Interact with real person authenticated users to get a better social experience.", "This user has not passed the real person authentication, please be careful to identify the other party's identity."
