[0040] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all 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.

[0041] Reference Figure 1 , showing a step flow chart of a method for authentication in a video conference provided by some embodiments of the present invention. The method can be applied to the server side, such as the server side can be a computing power server, and the computing power server can communicate with the video clients participating in the conference.

[0042] Specifically, the following steps may be included:

[0043] Step 101, in response to a function request of a target video conference terminal to start a virtual portrait, multi-dimensional feature information of the target video conference terminal is obtained.

[0044] Among them, the virtual portrait function is a function of using a virtual portrait to participate in a video conference, that is, using a virtual portrait instead of a real portrait in the video stream, such as a virtual portrait that is a fake participant generated using AI technology.

[0045] In actual applications, a virtual portrait function start button can be provided in the video conferencing client. The user can start the virtual portrait function by operating the start button. When it is detected that the target video conferencing end has started the virtual portrait function, multi-dimensional feature information can be used to perform multi-dimensional authentication on the target video conferencing end using the virtual portrait function.

[0046] In some examples, multi-dimensional authentication can be performed when it is detected that the target video conferencing end has started the virtual portrait function to determine whether the target video conferencing end has the authority to use the virtual portrait function. Multi-dimensional authentication can also be performed during the process of the target video conferencing end using the virtual portrait function to determine whether there are any abnormalities in the process of the target video conferencing end using the virtual portrait function.

[0047] In some examples, the server side (such as a computing server) can establish a connection with a video conferencing client, and then communicate with the video conferencing client, such as using the WebSocket protocol or HTTP / 2 protocol in the TCP / IP protocol family or the visual Internet protocol or other custom protocols for real-time communication.

[0048] In some examples, the video conferencing client can complete the protocol conversion link through the virtual connection manager, and the virtual connection manager is responsible for maintaining the connection status between the server side and the video conferencing client, including connection establishment, maintenance, disconnection and reconnection mechanisms.

[0049] In some examples, the server side can use TLS (Transport Layer Security) protocol or SSL (Secure Sockets Layer) protocol or video networking protocol to encrypt the transmitted data, and the video conferencing client can use RTP (Real-Time Transport Protocol) or RTCP (Real-time Control Protocol) or WebRTC protocol to transmit real-time video streams.

[0050] Step 102, verify the multi-dimensional feature information respectively to obtain a multi-dimensional verification result.

[0051] After obtaining multi-dimensional feature information, different strategies can be used for verification in different dimensions to obtain verification results in multiple dimensions, namely, multi-dimensional verification results.

[0052] In related technologies, different video conferencing platforms and devices may adopt different technical standards and protocols, resulting in poor compatibility and interoperability of virtual portrait authentication between different platforms and devices. This increases the difficulty of technology deployment and application, and also limits the popularization and promotion of the technology.

[0053] In the embodiment of the present invention, by adopting a multi-dimensional identity authentication strategy, comprehensive consideration of behavioral characteristics, biometric characteristics and environmental information, a continuous and dynamic authentication mechanism is adopted instead of a one-time identity authentication, thereby improving the compatibility and interoperability of virtual portrait authentication.

[0054] In some examples, the multi-dimensional feature information may be feature information related to the virtual portrait function, such as the multi-dimensionality may include a behavioral feature dimension, a biological feature dimension, and an environmental feature dimension.

[0055] For the behavioral characteristics dimension:

[0056] In some embodiments of the present invention, the multi-dimensional feature information includes real-time behavior feature information, the multi-dimensional verification result includes a behavior feature verification result, and before the multi-dimensional feature information is verified respectively to obtain the multi-dimensional verification result, the following is further included:

[0057] The historical behavior characteristic information of the target video conference terminal is obtained, and a behavior model for the target video conference terminal is established according to the historical behavior characteristic information.

[0058] In some examples, the historical behavior characteristic information includes any one or more of the following: historical keyboard usage information, historical mouse movement information, and historical gesture operation information.

[0059] In some embodiments of the present invention, the respectively verifying the multi-dimensional feature information to obtain a multi-dimensional verification result includes: using the behavior model to analyze the real-time behavior feature information to obtain a behavior feature verification result.

[0060] In some examples, the real-time behavior characteristic information includes any one or more of the following: real-time keyboard usage information, real-time mouse movement information, and real-time gesture operation information.

[0061] In actual applications, the historical behavior feature information of the target video conference terminal can be collected, and then analyzed through machine learning algorithms to establish a behavior model with client identification. When authenticating in the behavior feature dimension, the pre-established behavior model can be used to analyze the acquired real-time behavior feature information to obtain the behavior feature verification result.

[0062] In some examples, a behavior monitoring module can be deployed on a video conferencing client to record the user's keyboard typing, mouse movement, gesture operations and other behavior data. Then, feature extraction algorithms in machine learning, such as PCA (Principal Component Analysis) algorithm and LDA (Linear Discriminant Analysis) algorithm, can be used to extract behavioral feature information from the original behavior data, and then unsupervised learning (such as clustering algorithm) or supervised learning (such as classification algorithm) can be used to build a behavior model. For example, for new users, clustering algorithms can be used for preliminary classification, and for existing users, classification algorithms can be used for fine-grained recognition.

[0063] In some examples, new behavior data may also be collected periodically, and the behavior model may be updated using an online learning algorithm (such as incremental learning) to adapt to changes in user behavior.

[0064] For the biometric dimension:

[0065] In some embodiments of the present invention, the multi-dimensional feature information includes real-time biometric feature information, the multi-dimensional verification result includes a biometric verification result, and before the multi-dimensional feature information is verified respectively to obtain the multi-dimensional verification result, the following is further included:

[0066] Obtain pre-collected reference biometric information.

[0067] In some examples, the reference biometric information includes reference portrait feature information, and the reference portrait feature information is obtained from pre-stored historical images, such as facial feature information and limb feature information.

[0068] In some embodiments of the present invention, the respectively verifying the multi-dimensional feature information to obtain a multi-dimensional verification result includes: comparing the real-time biometric feature information with the reference biometric feature information to obtain a biometric feature verification result.

[0069] In some examples, the real-time biometric information includes real-time portrait feature information, which is obtained from the collected real-time images, such as facial feature information and limb feature information.

[0070] In practical applications, the video conferencing client can collect historical images before the video conference starts, and then extract and store reference portrait feature information by analyzing the historical images.

[0071] During a video conference, the video conference client can upload the real-time images collected by the biometric collection module according to the predetermined rules to obtain a real-time image, and then extract the real-time portrait feature information from the real-time image. After obtaining the real-time portrait feature information, the real-time biometric feature information can be compared with the reference biometric feature information to obtain the biometric verification result.

[0072] For the environmental feature dimension:

[0073] In some embodiments of the present invention, the multi-dimensional feature information includes real-time environmental feature information, the multi-dimensional verification result includes an environmental feature verification result, and before the multi-dimensional feature information is verified respectively to obtain the multi-dimensional verification result, the following is further included:

[0074] Obtain the pre-collected reference environment feature information.

[0075] In some examples, reference environment characteristic information includes any one or more of the following: reference terminal device information, reference geographic location information, such as the terminal device information is the device model, operating system version, and IP address obtained through the terminal's operating system API or hardware interface. For devices that support GPS, the data of the GPS module is directly read, and the geographic location information is the geographic location information located by GPS, or, for devices that do not support GPS, the geographic location information is the geographic location information located by the IP address, or the geographic location information is a combination of GPS positioning and IP address positioning. By combining GPS and network positioning technology, the accuracy of positioning can be improved.

[0076] In some embodiments of the present invention, the respectively verifying the multi-dimensional feature information to obtain a multi-dimensional verification result includes: comparing the real-time environmental feature information with the reference environmental feature information to obtain an environmental feature verification result.

[0077] In some examples, real-time environmental characteristic information includes any one or more of the following: real-time terminal device information, real-time geographic location information, such as terminal device information is the device model, operating system version, and IP address obtained through the terminal's operating system API or hardware interface. For devices that support GPS, the data of the GPS module is directly read, and the geographic location information is the geographic location information located by GPS, or, for devices that do not support GPS, the geographic location information is the geographic location information located by the IP address, or the geographic location information is a combination of GPS positioning and IP address positioning. By combining GPS and network positioning technology, the accuracy of positioning can be improved.

[0078] In practical applications, the video conference client can pre-set reference environment feature information before the video conference starts. During the video conference, the video conference client can obtain real-time environment feature information, and then compare the real-time environment feature information with the reference environment feature information to obtain the environment feature verification result.

[0079] For example, by comparing the geographic location information in the real-time environmental feature information with the geographic location information in the preset reference environmental feature information, it is determined whether the user uses the system within a reasonable range to obtain an environmental feature verification result.

[0080] Step 103: Generate a comprehensive authentication result of the target video conference terminal using the virtual portrait based on the multi-dimensional verification result, wherein the comprehensive authentication result is used to indicate whether the target video conference terminal has the authority to use the virtual portrait.

[0081] In actual applications, the server side can conduct a comprehensive analysis of the verification results of multiple dimensions to form a comprehensive assessment of the identity of the virtual portrait and obtain a comprehensive authentication result.

[0082] In some examples, verification rules and thresholds can be defined for each verification dimension (such as biometrics, behavioral characteristics, and environmental characteristics), and weighted scoring methods or decision tree algorithms can be used to comprehensively analyze the verification results of multiple dimensions to obtain a comprehensive authentication result.

[0083] In some embodiments of the present invention, a comprehensive authentication result of the target video conferencing terminal using the virtual portrait is generated based on the multi-dimensional verification result, including: determining the weight information of each dimension in the multi-dimensional verification result; combining the multi-dimensional verification result and the weight information of each dimension to generate a comprehensive authentication result of the target video conferencing terminal using the virtual portrait.

[0084] In practical applications, different weights can be set for different verification dimensions. For example, behavioral feature dimensions and biometric feature dimensions are the main verification dimensions, and higher weights can be set. Environmental feature dimensions are auxiliary verification dimensions, and lower weights can be set. Then, the weight information can be used to perform weighted summation on the verification results of each dimension to obtain a comprehensive authentication result.

[0085] In some embodiments of the present invention, after generating a comprehensive authentication result of the target video conference terminal using the virtual portrait according to the multi-dimensional verification result, the method further includes:

[0086] A restriction policy for the target video conference terminal to use the virtual portrait is generated based on the comprehensive authentication result.

[0087] In some embodiments of the present invention, the comprehensive authentication result includes a comprehensive authentication level, and generating a restriction policy on the use of the virtual portrait by the target video conferencing terminal based on the comprehensive authentication result includes: generating a restriction policy on the use of the virtual portrait by the target video conferencing terminal based on the comprehensive authentication level.

[0088] In actual applications, the comprehensive authentication results can include comprehensive authentication levels, such as low-risk level, medium-risk level, and high-risk level. Then, corresponding restriction strategies can be adopted for video conferencing clients of different risk levels, such as directly granting access rights to low-risk users; further verification or restriction of access rights may be required for medium-risk users; and access may be denied and security alerts may be triggered for high-risk users. Among them, access control is to adjust access rights according to the risk level of the user, such as limiting the access scope or frequency of high-risk users, and security alerts are to trigger the security alert mechanism for high-risk users and notify the administrator for further processing.

[0089] In some examples, the server side can log the access behavior and verification results of all users for subsequent auditing and tracing.

[0090] In some embodiments of the present invention, after generating a restriction policy on the target video conference terminal using the virtual portrait according to the comprehensive authentication result, the method further includes:

[0091] According to the restriction policy, a corresponding authority certificate is sent to the target video conferencing terminal, and the authority certificate is synchronized to the core server, so that the core server adopts the corresponding restriction policy to the target video conferencing terminal.

[0092] In actual applications, the server side can send a corresponding authority certificate to the target video conferencing terminal according to the restriction policy. The certificate is a decision pass made according to the results of the risk assessment. In some examples, the authority certificate contains user identification (or terminal identification), verification results, validity period and other information.

[0093] Moreover, the server side (such as a computing server) can establish a certificate synchronization mechanism with the core server (such as a visual network core server), and then can synchronize the certificate update with the core server (such as a visual network core server) to ensure that the core server can obtain the latest certificate information in a timely manner.

[0094] In an embodiment of the present invention, by responding to a functional request for starting a virtual portrait at a target video conferencing terminal, multi-dimensional feature information of the target video conferencing terminal is obtained, the multi-dimensional feature information is verified separately to obtain a multi-dimensional verification result, and based on the multi-dimensional verification result, a comprehensive authentication result of the use of the virtual portrait by the target video conferencing terminal is generated, thereby realizing authentication of the virtual portrait function in the video conference. Through multi-dimensional authentication of the virtual portrait function, the security of the video conference is improved.

[0095] Specifically, the embodiments of the present invention provide the following effects:

[0096] 1. Through multi-dimensional verification (including biometrics, behavior patterns, device information, and geographic location, etc.), user behavior data is collected and analyzed in real time to provide strong support for the formulation and optimization of security strategies.

[0097] 2. Support the integration of new verification technologies and methods, such as more advanced biometrics and AI-driven behavioral analysis, to ensure that the solution can continue to evolve and upgrade.

[0098] 3. Automated processing and instant feedback mechanisms reduce user waiting time and improve overall efficiency. Efficient user management and authentication processes can support concurrent access by large-scale users.
