Transparent User Authentication for Digital Rights Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional digital rights management systems often require users to engage in additional authentication steps, which can complicate the user experience and deter legitimate users, especially in scenarios where ease of access is desired.
Innovation Solution
A system and method for transparently authenticating users to a digital rights management entity, where a digital rights management server receives an authentication token from a remote computer system, verifies it, and issues credentials to the user, allowing seamless access to DRM-protected content without the need for direct user authentication with the DRM provider.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If DRM systems require additional authentication steps for users, then security and content protection are improved, but user experience and ease of access deteriorate
Solution Approach 1:
The system performs authentication actions in advance by establishing trust relationships between content providers and DRM servers before actual content access. Users are pre-authenticated through the content provider, and their authentication status is stored as credentials, eliminating the need for repeated authentication steps while maintaining security.
Solution Approach 2:
The content provider acts as an intermediary that bridges users and the DRM server. Instead of users directly authenticating with the DRM server, the content provider verifies user credentials and communicates authentication status to the DRM server, simplifying the user experience while maintaining security through the intermediary's verification process.
2Reliability
If DRM systems implement strict authentication verification, then unauthorized access prevention is improved, but system complexity and processing overhead increase
Solution Approach 1:
The authentication system is segmented into distinct functional components: user credential verification by the content provider, authentication token generation, and DRM server verification. This segmentation allows each component to perform its specific function independently, reducing overall system complexity while maintaining comprehensive security verification.

AI summary
Various embodiments of a system and method for transparently authenticating a user to a digital rights management entity are described. In various embodiments, a digital rights management server may be configured to receive an authentication token from a first remote computer system. Such authentication token may indicate that a particular user of the first remote computer system was authenticated by a first content provider of one or more content providers. In various embodiments, the digital rights management server may also be configured to verify the authentication token by determining that one or more portions of the authentication token were generated based on respective authentication information issued to the first content provider. In various embodiments, the digital rights management server may also be configured to, in response to verification of the authentication token, issue to the first remote computer system one or more credentials.
