Credential Sharing System via Blockchain Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing database systems face challenges in securely and trustfully transferring personal and verification information between disparate systems, as the trust in data is compromised when it passes through human intermediaries, leading to issues like data theft and misrepresentation.
Innovation Solution
A system that enables secure transfer of verifiable credentials using a processor-configured network system, where credentials are generated and verified using cryptographic keys on a public or semi-public distributed ledger, allowing users to control their privacy and data by determining which credentials to share, thus ensuring trust and security in information exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual data transfer through human intermediaries is used, then ease of operation is improved, but reliability of data trust deteriorates
Solution Approach 1:
The patent introduces a blockchain-based credential verification system as an intermediary between data sources and requesting systems. This mediator automatically verifies credentials through cryptographic proof without requiring human intermediaries, thus maintaining ease of operation while significantly improving data trust and reliability.
2Reliability
If system-to-system integrations are implemented, then reliability of data transfer is improved, but device complexity increases
Solution Approach 1:
The patent uses cryptographic copies (hashes) of credential data stored on blockchain networks. Instead of implementing complex system-to-system integrations, the system creates verifiable copies of credentials that can be independently verified by any requesting system, thereby maintaining high reliability while minimizing integration complexity.
3Reliability
If cryptographic verification on distributed ledger is used, then reliability of credential verification is improved, but use of energy increases
Solution Approach 1:
The patent performs cryptographic verification in advance by storing verified credential hashes on the blockchain network before they are needed. When credentials are requested, the system simply retrieves and verifies pre-computed cryptographic proofs rather than performing energy-intensive verification computations in real-time, thus maintaining high reliability while reducing energy consumption during operation.
Data Source
AI summary
A system for providing an application includes an interface and a processor. The interface is configured to receive an indication to provide an application to a device. The processor is configured to provide the application to the device. The application is configured to receive a request for credentialed information associated with a user from a requesting server; determine whether a stored credential satisfies the request for the credentialed information; and in response to a determination that the stored credential satisfies the request for the credentialed information: determine a response credential for responding to the request; determine that the user approves sharing the credentialed information indicated by the response credential; and provide the response credential to the requesting server.
