FIELD: computer equipment.
SUBSTANCE: method comprises: receiving biometric data directly from a biometric input element; obtaining a biometric signature based on biometric data; accessing an initial value characteristic of biometric data by obtaining an initial value from biometric data or a biometric signature; generating a secret key based on an initial value and a key generation function; obtaining a random number by introducing a secret key into a pseudorandom number generator; generating an encryption key based on the random number; encoding a biometric signature using a closed algorithm and an encryption key for generating a marker; output of a marker for safe storage in a security element or safe transmission to a secure server for registration or authentication of biometric data and deletion of biometric data and a biometric signature after the marker output.
EFFECT: technical result consists in ensuring safe authentication of biometric data.
