Active Content Playback Apparatus Intent-Based DRM
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital rights management (DRM) systems are complex, costly, and difficult for individuals to use, failing to accurately reflect content creators' intentions for privacy protection and content distribution, particularly in the context of digital content sharing.
Innovation Solution
An active content playback and creation apparatus that embeds intention engine code in executable files using a markup language, allowing content to be executed according to the creator's intentions while preventing leakage, using a standard player without dedicated software, and providing privacy protection through hooking APIs and condition-based control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional DRM systems are used for content protection, then copyright protection is provided, but system complexity and cost increase significantly
Solution Approach 1:
The patent extracts the core DRM functionality into a simplified intent-based system. Instead of implementing full DRM protocols, the system extracts only the essential protection mechanisms needed for content distribution, embedding them directly in executable files. This reduces system complexity while maintaining copyright protection through intent-based access control and embedded encryption keys.
Solution Approach 2:
The patent employs disposable encryption keys embedded in executable files that are used once for content protection and then discarded. Each executable file contains its own unique encryption key and intent metadata, eliminating the need for persistent DRM infrastructure. This approach reduces both system complexity and cost while providing adequate copyright protection for individual content distribution scenarios.
2Reliability
If traditional DRM systems are implemented, then content security is improved, but ease of operation deteriorates due to complex software installation and user interface
Solution Approach 1:
The patent implements self-service content protection where the executable file itself contains all necessary security mechanisms. The file automatically manages its own encryption keys, intent metadata, and access control logic without requiring external DRM software or complex user configuration. Users simply execute the file, and the embedded security system handles protection transparently, dramatically improving ease of operation while maintaining content security.
3Reliability
If dedicated DRM players are used, then content protection is enhanced, but adaptability decreases due to lack of compatibility between DRM systems
Solution Approach 1:
The patent creates a universal content protection mechanism that works across different platforms and players. By embedding intent-based security logic and encryption keys directly in the executable file rather than relying on external DRM systems, the solution achieves platform independence. Any standard executable file can carry protected content, making the system adaptable to various operating systems and players without requiring dedicated DRM software, thus enhancing both content protection and compatibility.
4Reliability
If content is distributed with fine-grained control, then privacy protection is improved, but device complexity increases due to need for tracking and management systems
Solution Approach 1:
The patent segments content protection into fine-grained intent units embedded in individual executable files. Each file contains specific intent metadata defining exact usage conditions (e.g., number of plays, time limits, device restrictions) rather than requiring centralized tracking. This segmentation enables precise privacy control at the content level without complex management systems, as each executable file independently enforces its own usage constraints through embedded intent logic.
