Digital Rights Locker for Secure Content Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital rights management systems face challenges in efficiently distributing and managing digital contents across various client devices, as they struggle to ensure secure access while preventing unauthorized access to digital contents.
Innovation Solution
A digital rights management platform that includes a coordinator device maintaining a digital rights locker, which processes digital contents, generates rights tokens, and enables client devices to access these contents securely through a network of proxy, retailer, and access providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If digital rights management systems distribute digital contents across various client devices, then accessibility and versatility improve, but security and prevention of unauthorized access deteriorate
Solution Approach 1:
The system segments digital contents into encrypted portions stored in a digital rights locker, separating the content from the decryption keys. This allows multiple client devices to access different portions of contents while maintaining security through distributed encryption management.
Solution Approach 2:
The patent introduces a digital rights locker as an intermediary component between content providers and client devices. This locker securely stores encrypted contents and manages decryption rights, enabling verified access while preventing unauthorized distribution across devices.
2Reliability
If digital rights management systems implement secure access control, then security improves, but device complexity and operational difficulty worsen
Solution Approach 1:
The digital rights locker enables client devices to autonomously manage their own access rights and decryption operations. Devices self-authenticate and self-manage content access without requiring complex centralized control, reducing operational complexity while maintaining security.
Solution Approach 2:
The system changes the state of digital contents from unencrypted to encrypted form, transforming the access mechanism. By changing the parameter of content encryption status, the system achieves secure access control without adding complex management overhead to individual devices.
3Reliability
If digital rights management systems prevent unauthorized access, then security improves, but efficiency and distribution speed deteriorate
Solution Approach 1:
The system performs preliminary encryption of digital contents before distribution, storing encrypted portions in the digital rights locker. This advance preparation allows rapid distribution to authorized devices without requiring real-time encryption operations, maintaining both security and efficiency.
Solution Approach 2:
The patent creates encrypted copies of digital contents that can be rapidly distributed to multiple client devices simultaneously. These pre-prepared encrypted copies enable fast distribution while the decryption process remains controlled and secure at the point of access.
Data Source
AI summary
A system and method relate to a platform for distributing digital contents (digital content) to various client devices. A digital rights management platform allows a content provider to forward digital contents that is automatically ingested and processed in accordance with various requirements associated with providing the digital contents to the client devices. Information regarding the ingested digital contents may be provided to a coordinator device that uses this information to form a digital rights locker associated with the digital contents. A client device accesses the digital rights locker to obtain a rights token, or a proof of purchase, that is used to obtain rights data for accessing the digital contents.
