Digital Media Fragmentation for Secure P2P Streaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for protecting digital content from unauthorized copying over the internet are inefficient and costly, as they often require expensive hardware and software to verify digital watermarks, and can be easily circumvented by pirate experts who can identify and manipulate these identifiers.
Innovation Solution
A method for securely downloading and streaming digital media content by segmenting it into coherent and fragmented parts, where the coherent content is played by reassembling the fragmented parts on the user's device, and the attribution linkage is used to trace cloning attribution, allowing for peer-to-peer distribution while maintaining security and reducing bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital watermarking is used to prevent unauthorized copying, then content protection is improved, but the cost and complexity of verification increases
Solution Approach 1:
The patent segments digital content into multiple fragmented parts distributed across different storage locations. Each fragment alone is insufficient for playback, requiring authorized assembly from multiple sources. This segmentation approach protects content without requiring complex watermark verification systems, as the fragments themselves provide the security mechanism.
2Ease of operation
If complete digital content is provided to consumers, then ease of operation is improved, but unauthorized copying increases
Solution Approach 1:
Content is divided into multiple fragments that must be assembled from different authorized sources to achieve complete playback. This maintains ease of operation for authorized users while preventing unauthorized copying, as pirates would need to compromise multiple distributed fragments simultaneously.
Solution Approach 2:
The patent implements a nested structure where fragmented content pieces are distributed within different storage systems or locations, and the complete content is reconstructed by nesting these fragments together in the correct sequence during authorized playback.
3Reliability
If traditional content protection methods are used, then security is improved, but bandwidth usage increases
Solution Approach 1:
By segmenting content into distributed fragments, the system reduces redundant bandwidth consumption. Each fragment is transmitted once and stored locally at authorized nodes, eliminating the need for repeated full-content transmissions while maintaining security through the distributed fragment architecture.

AI summary
A system and method for securely streaming/downloading and playing coherent digital content such as music and preventing its play by unauthorized users, facilitating a peer-to-peer sharing of cloned content. The system may include mass server/storage devices for receiving and storing digital content having predetermined gaps, and client devices communicating with the server/storage devices and providing authorization to proceed. During playing of the digital content by the client devices, the removed components may be reinserted into the missing gaps at the appropriate places, to allow the play or cloning of the coherent digital content.
