Personalized Visual Elements for Video Stream Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solutions for protecting digital video streams against illegal copying and distribution lack effective detection mechanisms, requiring complex analysis techniques to identify fraudulent copies.
Innovation Solution
A process that adds personalized visual elements to the video stream, allowing immediate identification of the intended recipient, which can be traced back to the source if the stream is copied or distributed illicitly, using a client-server system that generates, inserts, and removes these elements to maintain authentication information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If personalized visual elements are added to the video stream for identification, then the ability to identify fraudulent copies is improved, but the device complexity increases
Solution Approach 1:
The patent extracts the identification function from complex video analysis and implements it through simple visual elements embedded in the video stream. These visual elements contain authentication information that can be easily detected without complex analysis, resolving the contradiction between detection capability and system complexity.
Solution Approach 2:
The patent introduces visual elements as an intermediary carrier of authentication information. Instead of directly analyzing video content for fraud detection, the system uses these embedded visual elements as a mediator that simplifies the detection process while maintaining high identification accuracy.
2Loss of information
If visual elements are inserted into the video stream, then the identification of the intended recipient is improved, but the video stream quality may deteriorate
Solution Approach 1:
The patent applies local quality by inserting visual elements only in specific regions or frames of the video stream where they do not interfere with the overall video quality. The visual elements are localized to specific areas, allowing the majority of the video content to maintain its original quality while still providing authentication information.
3Measurement precision
If complex analysis techniques are used to detect fraudulent copies, then the detection accuracy is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent extracts the authentication information into separate visual elements that can be detected independently of complex video analysis. This allows fraud detection to be performed by simply checking for the presence and validity of these visual elements, greatly simplifying the operation while maintaining high detection accuracy.

AI summary
A process for distributing video streams to a plurality of addressees, comprising a marking step comprising adding at least one visual element to a video stream, which marking step applied to an original video stream common to all the addressees and which is personalized for each addressee by addition of a visual element specific to the addressee that allows rapid visual identification of the addressee, wherein the added visual element replaces part of the original video stream that is stored in complementary information on a multimedia server.
