Abstract: A biometric authentication platform (10) uses fault-tolerant distributed computing to determine if a supplied biometric sample and a sample stored in a registry are from the same person. A collection of reference samples is maintained in a distributed ledger (115) with immutable history of modifications. Results of matching are stored in a separate distributed ledger (125) providing an immutable history log. Coordinated use of both ledgers (115, 125) enable biometric authentication of registered users (140) in real time. Users (140) may interact with providers (150) and/or trusted circles of other users in order to recover user records from the user ledger (115).
