Blockchain Identity Verification via Permission Chains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional identity verification methods are inadequate for remote transactions, as physical documents are difficult to authenticate and digital images are insecure, necessitating a secure, distributed technique for verifying identities across different locations.
Innovation Solution
A blockchain-based system for storing verified identity documents and transactions, where identity profiles are strengthened over time through transaction history, allowing institutions to verify identities based on past transactions and permissions management, enabling secure remote authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical identity documents are used for verification, then identity authentication is reliable, but the verification process cannot be conducted remotely
Solution Approach 1:
The patent creates digital copies of physical identity documents and stores them on a blockchain. These digital replicas contain the essential verification information needed for remote authentication while maintaining the security and reliability of the original physical documents. The blockchain ensures that these copies cannot be tampered with or forged.
Solution Approach 2:
The patent introduces a blockchain-based intermediary system that mediates between the physical identity documents and the remote verification process. This intermediary layer allows institutions to verify identities remotely by accessing blockchain-stored identity information, eliminating the need for physical document examination while maintaining verification reliability.
2Ease of operation
If digital images of identity documents are used, then remote verification becomes possible, but security is significantly compromised
Solution Approach 1:
Instead of using vulnerable digital image copies, the patent stores structured identity data on the blockchain. This creates a secure digital representation that can be remotely accessed and verified without the security risks associated with traditional digital document images.
Solution Approach 2:
The patent combines multiple security mechanisms into a composite verification system: blockchain immutability, cryptographic hashing, permission-based access control, and institutional verification. This composite approach creates a security framework that is more robust than any single mechanism alone, enabling both remote verification and high security.
3Ease of operation
If identity verification is conducted without physical presence, then transaction convenience is improved, but authentication difficulty increases
Solution Approach 1:
The blockchain acts as an intermediary that simplifies the authentication process for remote transactions. Institutions can verify identities by accessing blockchain-stored identity information without needing to physically examine documents or be in the same location as the claimant, thus maintaining convenience while reducing authentication difficulty.
Solution Approach 2:
The system incorporates feedback mechanisms where institutions can verify identity information on the blockchain and receive confirmation of authentication status. This feedback loop enables remote verification to be as reliable and straightforward as physical verification, eliminating the increased difficulty that would otherwise accompany remote authentication.
Data Source
AI summary
System and media for determining whether to conduct a transaction with a consumer claiming an identity. Identity points for the identity are stored in a first blockchain. Past transactions conducted by the party are stored in a second blockchain. Permission to read and/or write to the various blockchains are stored in a third blockchain. When the consumer desires to conduct a transaction, they can append a permission for the counterparty to access the identity and/or transaction chains to their permission chain. The counterparty can then make an informed decision as to whether to conduct the transaction with the consumer based on the information stored in the various blockchains.
