SAFE BIOMETRIC AUTHENTICATION METHOD Russian patent published in 2010 - IPC G06K9/03 G07D7/00

Abstract RU 2406143 C2

FIELD: information technology.

SUBSTANCE: use of self-correcting codes, display of red, yellow and green colours by a traffic light for each image, analysis of the self-correcting codes through selected stable and unstable bits, directed search for unstable bits and combination of input biometric data. Input biometric data is combined by calculating their average values and dropping examples of controlled biometric parametres with the highest deviation from the average values. Correctness of the composite corrected code is monitored by hashing and comparing the obtained value with a standard hash function value.

EFFECT: high security of multi-biometric authentication of a user using several biometric images of said user with simultaneous provision for high user friendliness of multi-biometric systems and safe indication of correctness of input of each of the biometric images.
