Blockchain Use-Right Transfer for Cross-Provider Digital Items
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for providing electronic data services face challenges in managing copyright transfers across different service providers due to the use of dedicated DRM systems, which are costly and difficult to integrate, leading to user inconvenience and inefficiencies in data exchange.
Innovation Solution
A network system utilizing a blockchain to manage ownership rights of electronic items, enabling seamless transfer of use rights between users and service providers, ensuring tamper-resistant and fault-tolerant transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate registration and fee systems are used for each service provider, then service providers can manage their items, but user operability deteriorates and operational burdens increase
Solution Approach 1:
The patent applies universality by creating a unified blockchain-based system that handles ownership transfers across multiple service providers through a single interface. The blockchain serves as a universal ledger that all service providers can write to, eliminating the need for separate registration systems for each provider while maintaining secure ownership transfers.
Solution Approach 2:
The patent uses the blockchain as an intermediary between users and service providers. The blockchain mediates ownership transfers by providing a tamper-resistant, transparent ledger that records all transactions. This intermediary eliminates the need for users to interact with multiple separate registration systems while ensuring secure and verifiable ownership transfers.
2Reliability
If separate registration and fee systems are used for each service provider, then service providers can control their items, but operational costs increase
Solution Approach 1:
The patent merges multiple separate registration and fee systems into a single unified blockchain-based system. By combining these functions into one platform, the system eliminates redundant operational costs while maintaining reliable use right management across all service providers through a shared ledger.
Solution Approach 2:
The blockchain-based system provides universal functionality that handles registration, fee management, and ownership transfers for multiple service providers through a single system. This multi-functionality reduces operational costs by eliminating the need for separate systems while maintaining reliable control over use rights.
3Productivity
If traditional ownership transfer systems are used, then transactions can be processed, but tamper-resistance and reliability deteriorate
Solution Approach 1:
The patent replaces traditional mechanical or centralized ownership transfer systems with a blockchain-based system that uses cryptographic hashing and distributed consensus. This substitution provides inherent tamper-resistance through the blockchain's immutable ledger while maintaining efficient transaction processing through parallel operations and smart contracts.
Solution Approach 2:
The patent uses disposable cryptographic hash values and access keys that are generated for each transaction. These one-time use credentials ensure that once a transaction is processed, the data cannot be tampered with, providing both speed and security through ephemeral, non-reusable security tokens.
Data Source
AI summary
An apparatus for providing services, includes: circuitry that: receive, from a communication terminal of a user, a request for obtaining a particular item of one or more items provided by one or more service providers, information on the one or more items being managed on a blockchain system; transmits, to the blockchain system, a request for changing information on a use right of the particular item to indicate transfer of the use right to the user; and provides the particular item to the communication terminal of the user having the use right of the particular item.
