Video Call Face Authentication With Local Privacy Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G video customer service scenarios, there is a risk of leakage of user face image information during face authentication, compromising security.
Innovation Solution
A video call method involving a first terminal device that establishes a call with a second terminal device, receives face authentication requests, performs privacy protection processing on acquired face image information to obtain encrypted or authentication information, and sends it through a preset data channel for the second terminal device to determine the authentication result, thereby preventing image information leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face image information is sent directly to the public security information system for authentication, then authentication can be performed, but the security and privacy of the face image information deteriorates due to leakage risk
Solution Approach 1:
The patent introduces an intermediary authentication mechanism where the first terminal device performs face authentication locally using a local authentication database rather than directly transmitting face images to a public security information system. This intermediary approach maintains authentication reliability while preventing face image information leakage by keeping the authentication process decentralized and secure.
2Ease of operation
If automatic screenshot capturing is used to acquire face image information, then face authentication can be implemented, but the privacy security of the user deteriorates
Solution Approach 1:
The patent implements self-service by having the first terminal device perform face authentication locally using its own camera and local authentication database. The user simply needs to appear in front of the camera, and the system automatically captures and authenticates the face image without requiring manual intervention or transmitting sensitive data externally, thus maintaining privacy security while keeping the operation simple.
3Adaptability or versatility
If face image information is transmitted to external systems for authentication, then authentication functionality is achieved, but the security of the transmitted information deteriorates
Solution Approach 1:
The patent extracts the face authentication functionality from the external public security information system and relocates it to the first terminal device itself. By taking out the authentication logic from the external system and implementing it locally in the terminal device, the system maintains authentication versatility while significantly improving information security by eliminating the need to transmit sensitive face image data externally.
Data Source
AI summary
A video call method, an electronic device, and a storage medium are disclosed. The video call method applied to a first terminal device may include: establishing, by the first terminal device, a video call with a second terminal device; receiving face authentication request information from the second terminal device based on a preset data channel; acquiring face image information in response to the face authentication request information; performing privacy protection processing on the face image information to obtain encrypted information or authentication information; and sending the encrypted information or the authentication information to the second terminal device based on the preset data channel, such that the second terminal device determines a face authentication result of the first terminal device according to the encrypted information or the authentication information.
