DRM Content Transfer via Trusted Server Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital rights management (DRM) systems have security weaknesses, leading to unauthorized copying and distribution of digital content, which limits content offerings and complicates user experience.
Innovation Solution
A DRM system that securely transfers and manages digital content using trusted servers, peer-to-peer transfers, and kiosks, employing secure metadata, asymmetric cryptography, and public key infrastructure (PKI) to bind content to specific devices, ensuring secure handling and playback while preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If current DRM systems are used to control digital content, then content security is maintained to some extent, but security weaknesses allow unauthorized copying and distribution
Solution Approach 1:
The DRM system segments content protection by binding content to specific storage devices through unique identifiers. Each storage device receives content encrypted with its specific identifier, creating isolated security zones that prevent unauthorized copying while maintaining reliable content protection across multiple devices.
Solution Approach 2:
A trusted server acts as an intermediary between content providers and storage devices. The server verifies device authenticity, manages content distribution, and coordinates binding operations, thereby strengthening content security while preventing unauthorized access through a controlled mediation layer.
2Object-affected harmful factors
If DRM systems limit content offerings to maintain security, then unauthorized access is reduced, but content availability and user experience are compromised
Solution Approach 1:
The DRM system achieves universal content availability by enabling the same content to be securely bound to multiple different storage devices. Users can transfer and play content across various devices while maintaining security, thus providing versatile content access without compromising protection against unauthorized access.
Solution Approach 2:
The system dynamically adapts content distribution by allowing flexible binding and transfer operations between devices. Content availability is enhanced through dynamic permission management that adjusts access rights based on authenticated device identities, enabling versatile content access while maintaining security controls.
3Reliability
If existing DRM systems are implemented, then some level of content protection is achieved, but the systems are difficult to use and complicate user experience
Solution Approach 1:
The DRM system enables self-service operations where users can independently transfer content between their own storage devices through authenticated binding operations. The trusted server automatically verifies device ownership and handles content re-binding without requiring complex manual configuration, thus maintaining strong content protection while significantly improving ease of operation.
Solution Approach 2:
The system performs preliminary authentication and device verification actions before content transfer operations. By pre-establishing trust relationships and binding content to verified devices in advance, the system simplifies subsequent user operations while maintaining robust content protection, thereby improving user experience without compromising security.

AI summary
The present invention relates to digital rights management (DRM) for content that may be downloaded and securely transferred from one storage to another storage. The storage may be a disk drive, or network attached storage. The storage performs cryptographic operations and provides a root of trust. The DRM system enables secure copying or transfer of content from one storage device to another storage device. In this embodiment, a trusted server that is authenticated and trusted by both storage devices brokers the transfer of content. The trusted server may be a separate entity of the DRM system or may be a component or function of an existing server of the DRM system. In another embodiment, the storage devices may transfer content in a peer-to-peer fashion. The transfer of content may be authorized and controlled based on a digital certificate associated with the content.
