Video Analytics for Selective DRM Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Configuring digital rights management (DRM) for video monitoring systems is complex due to varying sensitivity levels across different cameras and within video streams, requiring dynamic protection of specific locations, objects, and events to ensure privacy and intellectual property protection.
Innovation Solution
A video processing system that analyzes video frames to detect locations, objects, or events and configures DRM accordingly, allowing selective application of DRM to protect sensitive information by obscuring or restricting access to specific parts of the video stream.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DRM is applied to protect sensitive information in video streams, then security and privacy protection are improved, but device complexity and difficulty of configuration increase significantly
Solution Approach 1:
The video processing system automatically analyzes video content to identify sensitive information and applies DRM protection without requiring manual configuration. The system serves itself by autonomously detecting sensitive data types (credit cards, social security numbers, medical information, etc.) and configuring appropriate DRM settings based on the detected content, eliminating the need for complex manual DRM configuration.
Solution Approach 2:
The system dynamically changes DRM parameters based on the detected sensitive information in the video stream. When sensitive data is detected, the system automatically adjusts DRM settings such as encryption level, access controls, and watermarked overlay parameters. This dynamic parameter adjustment allows the system to adapt protection levels to the specific content being displayed, resolving the contradiction between security and configuration complexity.
2Measurement precision
If DRM is configured for each camera and video stream individually, then protection precision is improved, but device complexity and time to configure increase enormously
Solution Approach 1:
The video processing system performs multiple functions simultaneously: it processes video from multiple cameras, detects sensitive information, and applies DRM protection across all streams through a single system. This multi-functional approach eliminates the need to configure each camera and video stream separately, reducing configuration time while maintaining precise protection where needed through automated content-based detection.
Solution Approach 2:
The system performs preliminary analysis of video content to identify sensitive information before applying DRM protection. By pre-detecting sensitive data types and locations in the video stream, the system can automatically configure appropriate DRM settings in advance, eliminating the need for manual configuration of each stream and significantly reducing overall configuration time while maintaining high protection precision.
3Reliability
If DRM protection is applied to sensitive areas or objects, then security is improved, but ease of operation decreases due to restricted access
Solution Approach 1:
The system applies DRM protection with different parameters to different regions or objects within the video stream based on their sensitivity. Sensitive areas such as displayed credit cards or social security numbers receive higher levels of protection with watermarked overlays and restricted access, while non-sensitive portions of the video maintain normal accessibility. This localized quality approach maintains ease of operation for non-sensitive content while providing enhanced security where needed.
Data Source
AI summary
Digital rights management (DRM) of video data is selectively applied to video data by a video processing system that receives a video, comprising a number of frames, and processes at least one frame from the video to determine the contents of the video. The digital rights management for the video is then configured based on the contents of the video.
