Blockchain Digital Rights Management Decentralized Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital rights management (DRM) solutions rely on a central rights locker, which is prone to failure and results in users losing access to content if the provider goes out of business or fails, as they store usage rights in a license dedicated to one user and platform.
Innovation Solution
Implementing a blockchain-based DRM system that generates a rights blockchain for users, allowing decentralized storage and management of usage rights, eliminating the need for a central rights locker by using a genesis block and adding new blocks for each content item, with cryptographic hashes ensuring integrity and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a central rights locker is used to store usage rights, then interoperability between platforms is improved, but reliability deteriorates because the system relies on a single point of failure
Solution Approach 1:
The patent segments the centralized rights locker into multiple distributed nodes forming a blockchain network. Each node stores a copy of the usage rights data, eliminating the single point of failure while maintaining interoperability across platforms through the decentralized ledger structure.
Solution Approach 2:
The patent introduces a blockchain-based intermediary layer that mediates between content providers and users. This decentralized intermediary replaces the traditional centralized rights locker, enabling interoperability while distributing reliability across multiple participants in the network.
2Reliability
If usage rights are stored in a license dedicated to one user and one specific platform, then security is improved, but adaptability deteriorates
Solution Approach 1:
The patent creates a universal license structure stored on the blockchain that can be accessed by multiple platforms and devices. The usage rights are encoded in a platform-agnostic format on the distributed ledger, allowing the same license to function across different ecosystems while maintaining cryptographic security.
Solution Approach 2:
The patent moves the storage dimension from local device storage to a distributed network layer. By storing usage rights on the blockchain rather than in platform-specific licenses, the system adds a new dimensional layer that transcends individual platform boundaries while maintaining security through cryptographic verification.
3Ease of operation
If a centralized rights locker provider is used, then ease of operation is improved, but loss of information worsens when the provider fails
Solution Approach 1:
The patent extracts the control of usage rights from the centralized provider and returns it to the user through cryptographic key pairs. Users hold their own private keys that grant access to their content rights on the blockchain, eliminating the risk of provider failure while maintaining ease of operation through automatic key management.
Solution Approach 2:
The patent enables users to self-manage their content access rights through cryptographic authentication. The blockchain automatically verifies and enforces usage rights without requiring intervention from a rights locker provider, allowing users to maintain access to their content independently of any single provider's operational status.

AI summary
Generating a rights blockchain storing rights of a user, including: receiving an enrollment request and a public key from the user; verifying that the user has a private key corresponding to the public key; generating a user identifier using the public key; and generating and delivering the rights blockchain having a genesis block including the user identifier to the user.
