Digital Content Store System with Embedded Rights Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital content distribution systems lack secure and controlled usage mechanisms, particularly in network environments, where digital rights management is not effectively enforced, allowing for unauthorized access and use of digital content.
Innovation Solution
A digital content store system that provides secure acquisition and distribution of digital content, utilizing a unique digital rights management system and back-end enabling system to control usage rights, allowing users to purchase licenses for specific usage, such as playing or burning content, while ensuring secure key management and encryption to prevent unauthorized use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital content is distributed freely across the network, then accessibility and ease of operation are improved, but security and control over usage rights deteriorate
Solution Approach 1:
The system segments digital content into encrypted portions with embedded usage rights information, separating the content from its access control mechanisms. This allows the content to be distributed widely while maintaining security through the embedded rights management system that controls playback and usage.
Solution Approach 2:
The patent introduces an intermediary rights management system that acts as a mediator between the content distributor and the end user. This intermediary embeds usage rights information within the content itself, enabling automated enforcement of usage restrictions without requiring constant network connection or external verification.
2Reliability
If digital rights management systems are implemented, then security and control over usage rights are improved, but device complexity increases
Solution Approach 1:
The system implements self-service rights management by embedding usage rights information directly within the digital content. The content itself carries the instructions for its own usage control, eliminating the need for complex external rights management infrastructure and reducing system complexity while maintaining security.
Solution Approach 2:
Usage rights information is preliminarily embedded within the digital content during the distribution process. This preliminary action ensures that rights management is built into the content structure itself, reducing the need for complex runtime verification systems and simplifying the overall rights management architecture.
3Reliability
If usage rights are strictly enforced, then security against unauthorized use is improved, but adaptability and versatility of content usage deteriorate
Solution Approach 1:
The system employs dynamic rights management where usage permissions are not fixed but can be adjusted based on the specific content and user needs. The embedded usage rights information allows for flexible configuration of playback restrictions, enabling content to be adapted for different usage scenarios while maintaining security through the same technical framework.

AI summary
The digital content store provides users with an opportunity to purchase authorized usage of digital content, such as single or multiple music tracks, video, movies, and/or video games. The users can also buy license to a desired track for a fixed number of times, e.g. preferably the users can listen on three different machines simultaneously. Users can also burn a play list of X number of times, for example ten. The burn limit preferably applies to the play list, not the song. Mixed media capability is provided that allows the purchase of digital content and/or physical media. The digital content store system comprises a unique digital rights management system and a back-end enabling system that controls these digital rights.
