Secure Codec System for Digital Content Piracy Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increased availability of digital content has led to significant intellectual property theft due to lack of effective protection, with content being intercepted, stolen, and redistributed, resulting in substantial financial losses for content owners and providers.
Innovation Solution
A secure digital compressor/decompressor (CODEC) system that authenticates content sources, determines consumer entitlements and rights, and decrypts and decompresses content based on these rights, establishing a trust relationship to minimize piracy and protect against hacking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital content is made widely available over networks, then consumer access and convenience are improved, but intellectual property theft and piracy increase
Solution Approach 1:
The patent introduces a secure CODEC system as an intermediary component between the content source and the consumer device. This secure CODEC acts as a trusted mediator that enforces access control policies, authentication mechanisms, and encryption/decryption operations. By placing this intermediary layer, the system enables wide content distribution while preventing unauthorized access and piracy, thus resolving the contradiction between accessibility and security.
2Object-affected harmful factors
If content protection mechanisms are implemented, then piracy is reduced, but system complexity increases
Solution Approach 1:
The patent merges multiple security functions (authentication, authorization, encryption, decryption, and content protection) into a single integrated secure CODEC component. By combining these previously separate security mechanisms into one unified device, the system achieves effective piracy protection while reducing overall system complexity. The secure CODEC consolidates what would otherwise be multiple separate security systems into a single coherent implementation.
3Reliability
If secure authentication and encryption are performed, then content security is improved, but processing time increases
Solution Approach 1:
The patent implements preliminary authentication and key establishment actions before the actual content transmission and decryption processes. The secure CODEC pre-authenticates users, pre-establishes encryption keys, and pre-configures security parameters before content delivery begins. This preliminary action ensures that when content is actually processed and decrypted, the security operations are already optimized and configured, minimizing the time penalty associated with security processing during content delivery.
Data Source
AI summary
A system and method is arranged to provide compression and decompression of digital content in a secure manner. The system is configured to authenticate a source of the digital content, and to further determine a consumer's entitlements and rights for access to the digital content. Based upon the determined entitlements and rights for access, the system is directed to decrypt, and decompress the digital content. In one embodiment, a component of the system is enabled to establish a trust relationship with at least one other component of the system, to minimize an opportunity for piracy of the digital content. In another embodiment, a secure clock is directed to provide protection against hackers that may employ an in-circuit emulator, or the like.
