Video Stream Face Masking for Privacy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video media streams pose a threat to privacy as they can be misused, leading to potential harm for individuals participating, necessitating control over content to ensure only approved individuals are visible.
Innovation Solution
An electronic device and social media server system that uses face detection and identity recognition to identify individuals with social media relationships to the user, seeking approval for participation in the video stream, with masking functionality to conceal non-approved individuals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face detection and identity recognition are implemented to control video media stream content, then privacy protection is improved, but device complexity increases
Solution Approach 1:
The patent introduces a social media server as an intermediary that hosts a database of facial features and social relationships. Instead of storing and processing all facial data locally on electronic devices, the system offloads the database storage and identity verification tasks to the server. This reduces device complexity while maintaining privacy protection through centralized facial recognition and approval management.
2Reliability
If continuous network access is required for identity recognition and approval processes, then reliability of content control is improved, but energy consumption increases
Solution Approach 1:
The system performs preliminary actions by establishing social relationships and storing facial features in advance on the social media server. When a video media stream is generated, the electronic device can quickly perform identity recognition by comparing detected faces against pre-stored facial data from approved individuals, reducing the need for continuous network communication and lowering energy consumption during actual stream generation.
Solution Approach 2:
The electronic device performs local face detection and comparison operations using the pre-stored facial features from approved individuals. The device serves itself by conducting preliminary identity verification locally without requiring continuous network access to the social media server, thereby reducing energy consumption while maintaining content control reliability.
3Reliability
If approval seeking is implemented for each individual in the video media stream, then privacy protection is improved, but productivity decreases
Solution Approach 1:
The system performs preliminary approval actions in advance by establishing social relationships on the social media platform. Users pre-approve which individuals are allowed to appear in their video media streams. When generating a video stream, the system automatically verifies identities against these pre-approved lists, eliminating the need for real-time approval requests and maintaining both privacy protection and generation efficiency.

AI summary
Controlling content in a video media stream is presented. The controlling comprises: imaging a scene with a camera (42) of an electronic device (10); detecting, using a face detection function (22, 113), one or more faces present in the imaged scene; identifying, using an identity recognition function (23, 114), an individual having a face from among the one or more detected faces by determining that the face is a face of an individual having a social relationship on social media with a user of the electronic device (10); seeking approval, using an approval function (24, 115), from the identified individual to participate in the video media stream; and upon an approval from the identified individual to participate in the video media stream, generating the video media stream, using the camera (42) of the electronic device (10), with the face of the identified individual being visible.
