GENERATING A BIOMETRIC DIGITAL SIGNATURE FOR IDENTITY VERIFICATION Russian patent published in 2022 - IPC G06F21/32 H04L9/32 

FIELD: information security.

SUBSTANCE: invention relates to a system and methods for identity verification. The method for verifying the user’s identity includes reading biometric information from the user, generating biometric data from biometric information, hashing at least a fragment of biometric data to generate a biometric digital signature for the user. The method also contains storing at least a fragment of the user’s biometric digital signature in the hosting biometric digital signature of user devices corresponding to each of at least n people, so that the combination of hosting biometric digital signatures for at least m of n people contains all of the user’s biometric digital signatures, where the number m is more than half numbers n. The method contains the transfer of a biometric digital signature to the verification node; restoration of the previous biometric digital signature from fragments of hosting biometric digital signatures; determination that the biometric digital signature is identical to the previous biometric digital signature of the user.

EFFECT: increase in the security level of the user's biometric digital signature.
