Cloud-Based Watermark Schema for Automatic Piracy Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital watermarking systems are ineffective in preventing piracy and tracing unauthorized use of media content due to manual detection processes, lack of compatibility between different vendors' techniques, and inability of client devices to detect and report piracy events automatically.
Innovation Solution
A cloud-based system for managing group watermarking data, where client devices fetch a watermark schema from cloud storage, identify and verify group watermarking data, and determine authorization for media content playback, inhibiting playback and logging piracy events if unauthorized, while allowing both private and group watermarks to be used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual watermark detection processes are used, then detection capability is provided, but productivity is reduced and loss of time increases
Solution Approach 1:
The client device automatically performs watermark detection and piracy event reporting without requiring manual intervention. The system self-services by fetching watermark schemas, detecting watermarks in media content, and automatically reporting piracy events to content providers, thereby resolving the contradiction between providing detection capability and maintaining high productivity.
2Adaptability or versatility
If each content provider uses their own watermarking technique, then customization is achieved, but adaptability deteriorates due to incompatibility between different watermarking schemes
Solution Approach 1:
The patent implements a universal watermark schema format that can represent multiple different watermarking techniques. The client device is designed to handle various watermarking schemes through a unified interface, allowing different content providers to use their preferred techniques while maintaining compatibility across the system. This resolves the contradiction by enabling both customization and adaptability.
Solution Approach 2:
The watermark schema acts as an intermediary layer between different watermarking techniques and the detection system. By standardizing the representation of watermarks through schemas that can describe various embedding methods, the system mediates between diverse watermarking approaches and enables universal detection without requiring the client device to understand each specific technique's internal complexity.
3Reliability
If digital watermarking is used for source tracking, then piracy tracing capability is provided, but reliability is reduced because watermarking schemes are applied ad hoc and may corrupt each other
Solution Approach 1:
The system performs preliminary watermark embedding with proper planning and coordination before distribution. Content providers embed watermarks according to standardized schemas that account for potential interactions with other watermarks. This preliminary action ensures that watermarks are inserted in a manner that maintains their detectability and prevents corruption, thereby improving reliability while managing complexity through advance preparation.
4Reliability
If passive watermarking protection is used, then copyright information is embedded, but effectiveness is reduced because unauthorized use cannot be directly prevented
Solution Approach 1:
The system implements automatic feedback loops where client devices continuously monitor media content for watermarks and automatically report piracy events to content providers. This automated feedback mechanism transforms passive watermarking into an active protection system that can immediately identify and report unauthorized use, improving effectiveness while increasing automation. The feedback loop enables real-time piracy detection and response without manual intervention.
Data Source
AI summary
A method, apparatus, article of manufacture, and a memory structure for managing media content having group watermarking data is disclosed. The method comprises transmitting a request to receive the media content from a content playback device, receiving a response to the transmitted request, fetching, by the content playback device according to the response, the requested media content and a watermark schema, the watermark schema fetched from cloud-based storage, identifying, by the content playback device, the group watermarking data in the media content according to the fetched watermarking schema, determining, by the content playback device if the media content is authorized for provision according to the group watermarking data and the fetched watermarking schema, and providing the media content for playback according to the determined authorization.
