A biometric authentication platform uses fault-tolerant distributed computing to determine if a supplied biometric live scan and template are from the same person. Features provide additional protection for biometric data. The template and live scan may be encrypted using a symmetric encryption key. The encrypted template and live scan may be sent with copies of the symmetric key, each copy further encrypted by a public key associated with one processor's public-private key pair. Each processor may decrypt a copy of the symmetric key, which may then be used by the processor for decrypting the live scan and template for matching. A decentralized user ledger may store an encrypted copy of the biometric template, with the key stored locally in a registered device. Alternatively, a decentralized user ledger may store a hash of the biometric template, for verification of a template that is maintained on a registered device.

Biometric data protection during decentralized biometric authentication

A biometric authentication platform () 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 () with immutable history of modifications. Results of matching are stored in a separate distributed ledger () providing an immutable history log. Coordinated use of both ledgers () enable biometric authentication of registered users () in real time. Users () may interact with providers () and/or trusted circles of other users in order to recover user records from the user ledger ().
