  • Identity verification using computer-implemented decentralized ledger
    Patent number: 10382965
    Abstract: An identity verification application receives data encapsulating a request to verify an identity of a user that includes user-provided identification data. Thereafter, the identity verification application then hashes the user-provided data and traverses a decentralized ledger including a data structure comprising a plurality of linked segments to identify a match of the hash of the user-provided identification data. The identity verification application then provides verification data that either (i) confirms the identity of the user if the hash of the user-provided identification data has a match in the decentralized ledger, or (ii) rejects the identity of the user if the hash of the user-provided identification data does not have a match in the decentralized ledger. Related apparatus, systems, techniques and articles are also described.
