Premises Content Distribution via Universal Security Framework
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital content delivery systems face challenges in securely managing and transferring protected content across diverse hardware and software environments within a user's premises network, lacking a comprehensive and flexible mechanism for secure content sharing and control, especially in dynamic and heterogeneous network topologies.
Innovation Solution
The system enables secure content management and distribution by authenticating devices, browsing, and transferring protected content between authorized devices within a premises network using a standardized security architecture and Universal Plug and Play (UPnP) interface, maintaining content protection through cryptographic elements and secure microprocessors, and allowing seamless communication across different security frameworks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vendor-specific security packages are used in different devices, then content protection is maintained, but interoperability between devices is limited
Solution Approach 1:
The patent implements a universal security framework that allows devices with different vendor-specific security packages to interoperate through a common interface. The security framework includes standardized protocols and data structures that enable cross-vendor content protection while maintaining compatibility with proprietary security implementations, thus achieving both reliability and adaptability
2Reliability
If manual security configuration is implemented, then security control is precise, but user convenience is reduced
Solution Approach 1:
The system automatically performs security configuration, device authentication, and content protection setup without requiring manual user intervention. Devices self-register with the security framework, automatically negotiate security parameters, and establish protected content sharing relationships through automated protocols, thereby maintaining precise security control while significantly improving user convenience
3Adaptability or versatility
If content is transferred between devices with different security frameworks, then device compatibility is improved, but security management complexity increases
Solution Approach 1:
The patent introduces a universal security framework as an intermediary layer between devices with different vendor-specific security packages. This framework provides standardized protocols, data structures, and authentication mechanisms that mediate between proprietary security systems, enabling content transfer across diverse devices while abstracting away the complexity of managing multiple security frameworks
Data Source
AI summary
Apparatus and methods for protected content access, browsing and transfer over a network. In one embodiment, the network comprises a premises (e.g., residential) Local Area Network (LAN), and the apparatus comprises a server and renderer consumer premise equipment (CPE). The renderer CPE scans the network to search for a server CPE that implements a compatible security framework. The renderer authenticates itself with the server, and the server allows content browsing and selection access only to an authorized and authenticated renderer. A negotiation and exchange protocol comprises messages exchanged between the renderer and the server that include one or more of device identification, encryption key exchange, digital certificates and information regarding security package used by each CPE.
