Systems and methods for providing block chain-based multifactor personal identity verification

摘要

Block chain-based multifactor personal identity verification. A first and second verification address (i.e. an address indicating a particular location on a blockchain) may be assigned to an individual having a previously verified identity, an identifier for the individual and biometric data of the individual is stored in the blockchain at the assigned first verification address and second biometric data, and possibly a second identifier, is stored at the second verification address. A request to verify an individual’s identity is received from a client-side device, the request containing a received identifier(s) and received biometric data, the request indicating the associated blockchain verification address(es). The stored identifier(s) and biometric data in the blockchain are retrieved from the specific address(es) and upon successful matching of the supplied and retrieved identifier(s) and biometric information and possibly also a supplied private key matching the associated private key, identity verification is successful, which may involve signing a verification possibly using the associated private key related to the verification address. Alternatively, an identity verification request from a second computing device may be verified. Users, different to the individual, have different access to the stored data based on their respective private keys.
