Blockchain Identity Proofing via Federation Protocols
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the blockchain environment, there is a need to tie blockchain identities back to verifiable individual identities, especially for cases where identity proofing is required from trusted parties.
Innovation Solution
The system and method for blockchain identity proofing via federation protocols from trusted parties involve a digital wallet application receiving a customer login and request for an assertion, redirecting the session to a financial institution backend for authentication and verification, and writing the assertion to a distributed ledger.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain identity is created independently without external verification, then identity creation is simple and fast, but the identity cannot be tied to verifiable real-world individuals
Solution Approach 1:
The patent introduces trusted third-party entities (financial institutions, government agencies) as intermediaries that issue cryptographic proofs about user identities. These intermediaries bridge the gap between anonymous blockchain identities and verified real-world identities by providing cryptographically signed attestations that link the two without revealing sensitive information.
Solution Approach 2:
The system segments the identity verification process into separate components: identity creation on blockchain, external verification by trusted parties, and cryptographic proof generation. This allows each component to operate independently with specialized functions, reducing overall system complexity while improving reliability.
2Reliability
If traditional centralized identity verification is used, then identity proofing is reliable, but the system lacks decentralization and single points of failure
Solution Approach 1:
The patent creates a universal identity proofing system where multiple different trusted entities (banks, governments, other organizations) can all issue standardized cryptographic proofs that are recognized across the blockchain network. This multi-functional approach allows any verified entity to serve as an identity anchor, providing both reliability through diverse verification sources and decentralization through distributed trust.
3Ease of operation
If sensitive personal information is stored on blockchain for verification, then identity verification is straightforward, but security risks and privacy concerns increase
Solution Approach 1:
Instead of storing actual sensitive personal information on the blockchain, the system stores cryptographic proofs and hashes that serve as verifiable copies. These cryptographic representations contain all necessary verification information without exposing the underlying sensitive data, maintaining verification simplicity while eliminating security risks associated with storing actual PII on distributed ledgers.

AI summary
Blockchain identity proofing via federation protocols is disclosed. A method may include: receiving, at a digital wallet application for a financial institution on a customer electronic device, a customer login from a customer; receiving, by the digital wallet application and from the customer, a request for an assertion, wherein the request redirects a session with the digital wallet application to a financial institution backend via a financial institution website or a financial institution application using a federation protocol; authenticating, by the financial institution backend, the customer; confirming, by the financial institution backend, the assertion using verified customer information in a verified customer information database; redirecting, by the financial institution backend, the session to the digital wallet application; returning, by the financial institution backend and using the federation protocol, the assertion to the digital wallet application; and writing, by the digital wallet application, the assertion to a distributed ledger.
