Anchor Point DRM Security Threshold Enforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Digital Rights Management (DRM) technologies are inadequate, costly, invasive, and inconvenient, leading to unauthorized copying and distribution of digital content, which increases transactional costs and discourages widespread acceptance.
Innovation Solution
The implementation of an anchor point-based DRM system that binds digital rights to a secure, unique physical object, ensuring that rights are managed within a controlled domain, with access restricted to components meeting a defined security level, thereby preventing unauthorized access and leakage of decryption keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional DRM approaches are implemented to protect digital property rights, then security against unauthorized copying is improved, but device complexity and transactional costs increase
Solution Approach 1:
The system divides the DRM protection into separate components: anchor points embedded in device components, binding records stored in secure storage, and domain identifiers assigned to components. This segmentation allows each component to have a specific security function rather than requiring a complex centralized DRM system.
Solution Approach 2:
The patent introduces anchor points as intermediary secure elements embedded in device components. These anchor points act as mediators that verify domain membership and enable decryption keys to be released only to authorized components within the same domain, simplifying the overall DRM architecture.
2Reliability
If existing DRM systems are deployed to prevent digital property theft, then copyright protection is improved, but user convenience deteriorates due to invasive controls and potential loss of licensed copies
Solution Approach 1:
The system enables self-service DRM protection where the anchor points and binding records automatically verify domain membership and manage decryption key distribution without requiring user intervention. Licensed copies are protected through automatic domain verification rather than invasive user controls.
3Reliability
If security measures are increased to prevent key leakage outside the user's domain, then digital property security is improved, but device complexity and transactional costs worsen
Solution Approach 1:
The patent implements local quality by assigning domain identifiers to specific device components and using anchor points with binding records that are localized to each component. This allows security verification to occur locally at the component level rather than requiring complex centralized security enforcement.

AI summary
Digital rights management (DRM) can be effectively implemented through use of an anchor point and binding records within a user's anchor point domain. Assigning security levels to various components within an anchor point based DRM system and evaluating them against a security criterion provides additional protection against authorized access of the digital content. The content provider may specify the security criterion (e.g., a security level threshold), and the ability to use the digital content is denied or granted based on the ability of components to satisfy this criterion. For example, the ability to use a digital property instance is granted to a content handler that satisfies the security criterion and denied to a content handle that does not satisfy the security criterion.
