Matrix Barcode Embedding for Audiovisual Source Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unauthorized recording and distribution of audiovisual content pose challenges for copyright owners, as existing technologies lack effective methods to track the original source and owner of copyrighted material.
Innovation Solution
A method and system that embeds a matrix barcode within audiovisual content, which includes identification data about the content and the content receiver, allowing for the determination of the original source and owner, even when the content is shared or uploaded online.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital content is shared and distributed freely, then accessibility and ease of operation improve, but copyright protection and reliability deteriorate
Solution Approach 1:
The system embeds matrix barcodes containing unique receiver identification data into content before distribution occurs. This preliminary watermarking ensures that when content is shared or uploaded to the internet, the original source can be identified, thus maintaining copyright protection while allowing free sharing.
Solution Approach 2:
The matrix barcode acts as an intermediary element that carries identification information within the content itself. This intermediary structure enables tracking of content origin without interfering with the content's usability or sharing capabilities.
2Reliability
If content is watermarked with identification data, then copyright protection improves, but device complexity and manufacturing precision worsen
Solution Approach 1:
The system replaces complex physical tracking mechanisms with a digital matrix barcode embedded in the content. Instead of requiring sophisticated hardware to track content distribution, the solution uses optical/image processing techniques to read and analyze the embedded barcode, significantly reducing system complexity.
Solution Approach 2:
The matrix barcode is copied along with the content through various distribution channels. This copying mechanism ensures that the identification data travels with the content without requiring additional tracking infrastructure, simplifying the overall system.
3Measurement precision
If matrix barcode is embedded in content, then source tracking precision improves, but content quality and manufacturing precision worsen
Solution Approach 1:
The matrix barcode is embedded in specific localized areas of the content (such as corners or borders of video frames) rather than throughout the entire content. This localized approach ensures that the tracking functionality is maintained while minimizing impact on the overall content quality and visual experience.
Data Source
AI summary
A system for fingerprinting audiovisual content. The system includes a content receiver and a display device in communication with the content receiver. The content receiver is configured to receive a video signal, where the video signal includes audiovisual content. The content receiver may then be configured to generate a matrix barcode that includes identification data. The content receiver is also configured to create a fingerprinted content that includes the audiovisual content from the video signal and the matrix barcode. The content receiver may then be configured to output the fingerprinted content. The display device is configured receive the fingerprinted content form the content receiver. Also, the display device is configured to display the fingerprinted content.
