Blockchain User Authentication With Root-System Identity Retrieval

Multiple institutions merge their authentication systems into a single shared authentication system. The patent describes how institutions participate in a common authentication framework where authentication records are stored and verified across the network, eliminating the need for each institution to maintain separate authentication infrastructure while maintaining security through distributed verification.

The authentication system is designed to serve multiple institutions simultaneously with a single authentication record. The patent shows how one authentication interaction can be recognized by multiple participating institutions through the shared ledger, allowing the system to perform multiple authentication functions across different institutions without requiring repeated authentication processes.

The patent extracts and stores authentication records in a separate distributed ledger system independent of personal information databases. Authentication interactions are recorded on the blockchain without requiring institutions to share or store sensitive personal data, separating the authentication verification function from personal information storage while maintaining authentication accuracy through cryptographic proof.

The blockchain ledger acts as an intermediary that enables authentication verification without direct sharing of personal information between institutions. The patent describes how the distributed ledger mediates the authentication process by storing verification records that institutions can query without accessing each other's personal data, reducing information security risks while maintaining authentication precision.

The authentication system is segmented into distributed nodes across multiple institutions rather than being centralized in a single authority. The patent shows how the authentication ledger is divided and replicated across participating institutions, with each node maintaining a copy of the authentication records. This segmentation reduces reliance on any single central authority while maintaining system functionality, thereby increasing trust through distributed verification.

The distributed ledger provides continuous feedback and verification of authentication records across all participating institutions. The patent describes how each institution can verify the authenticity and integrity of authentication records through cryptographic proofs and consensus mechanisms, creating a feedback loop that enhances trust in the system without requiring complex centralized management.
