FIELD: engineering of systems for protecting communication channels, which realize claimed method for user authentication on basis of biometric data by means of provision and extraction of cryptographic key and user authentication.
SUBSTANCE: in accordance to the invention, neither biometric template nor cryptographic user key are explicitly represented in information storage device, without provision of biometric sample and information storage device with a pack stored on it, any cryptographic operations with data are impossible.
EFFECT: creation of biometric access system and method for provision/extraction of cryptographic key and user authentication on basis of biometry, increased key secrecy level, increased reliability, expanded functional capabilities and simplified system creation process.
