INTERACTIVE METHOD OF BIOMETRIC USER AUTHENTICATION Russian patent published in 2018 - IPC G06K9/62 

FIELD: biometrics.

SUBSTANCE: invention relates to biometric authentication methods. On the side of the authentication center (AC) a request signal sent by a computer tool (CT) user is formed, and a decision on authentication by comparing the response received from the user with the biometric characteristics of legitimate users from the AC database is taken. Request signal for each successive authentication cycle is formed again, according to the program ensuring the inclusion of the part controlling at least one of the information display devices in the CT in its composition. Request signal is formed so that its audio and/or visual display is an irritant, stimulating a physiological response at the unconscious level, depending on his individual characteristics, which is dynamically registered by means of at least one sensor in the CT. It is taken into account when forming the response signal transmitted by the AC, on the side of which the authentication solution is generated by means of calculations with the initial data presented by the response received and characteristics of legitimate users.

EFFECT: technical result consists in improvement of reliability of user authentication.
