User-Attributed Rights Segmentation in DRM Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Digital Rights Management (DRM) systems lack user influence in processing DRM rights, making them inflexible and unable to meet end-user needs, particularly in Authorized Domain Digital Rights Management (AD-DRM) systems where management of rights is solely determined by content providers and distributors.
Innovation Solution
A method that allows users to introduce user-attributed rights as further restrictions on received DRM rights within the DRM system, enabling users to control access and usage of content by deriving Authorized Domain (AD) specific rights, using a Rights Program Template (RPT) to simplify the process and provide flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If DRM rights are processed solely by content providers and distributors, then rights management control is maintained, but user flexibility and influence are reduced
Solution Approach 1:
The patent segments rights management into two distinct layers: provider-defined DRM rights (base restrictions) and user-defined user-attributed rights (additional restrictions). This segmentation allows users to independently add their own restrictions without modifying the original DRM rights structure, thereby increasing user flexibility while maintaining clear separation of responsibilities and avoiding excessive complexity in the overall rights management system.
2Ease of operation
If users are allowed to add further restrictions on DRM rights, then user influence is improved, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary mechanism (user-attributed rights) that mediates between the provider's DRM rights and the user's control needs. Users add their restrictions through this intermediary layer without directly modifying the original DRM rights. The system processes both layers independently and combines their effects, simplifying user operations while managing complexity through structured separation of right types and processing stages.
3Adaptability or versatility
If multiple rights mechanisms are employed, then user-specific control is improved, but architecture complexity increases
Solution Approach 1:
The patent creates a universal rights management framework where both provider-defined DRM rights and user-defined user-attributed rights operate within the same system architecture. The system is designed to handle multiple types of rights (DRM rights, user-attributed rights) and their combinations in a unified manner, allowing rights customization without requiring separate architectural systems. This multi-functional approach enables flexible rights configuration while maintaining a single, integrated rights management architecture.

AI summary
This invention relates to a method of processing rights relating to content, that can be communicated between devices. Typically, a Digital Rights Management (DRM) system imposes limitations of use and distribution, imposed by the service provider, content provider or distributor. The method of the invention renders it possible for a user who has received DRM rights to restrict the right further. The invention is more particularly related to the receipt of DRM rights to Authorized Domain Digital Rights Management (AD-DRM) systems and the introduction of user attributed rights in the form of further restrictions introduced to the received DRM rights. The invention further relates to a Rights Program Template (RPT) facilitating the introduction of such further restrictions in a user friendly way. Finally, the invention relates to a system supporting the method of the invention.
