METHOD OF GENERATING SET OF ACCESS KEY PARAMETRES AND SYSTEM FOR VERIFYING IDENTITY OF PERSON FROM FINGERPRINTS Russian patent published in 2009 - IPC G06K9/46 

FIELD: protection equipment.

SUBSTANCE: invention relates to biometric control and identification. For this purpose, fingerprints of a person are recorded using a sensor and initial data are formed. Characteristic data are obtained, which are chosen taking into account statistical confidence of identifying a person and a set of access key parametres are generated. At least three fingerprints are recorded, which are then used to generate at least two sets of extended access key parametres. The system for verifying identity of a person from fingerprints has sensors, a device for forming initial data, a device for obtaining characteristic data, device for generating a set of access key parametres, a device for comparing set of access key parametres with standard data, and a data output device. The system also has a device for generating a set of extended access key parametres. The data output device identifies a person as having access rights, if there is a complete match in the comparing device of at least, one set of extended access key parametres with the set of standard data.

EFFECT: increased selectivity of access key, increased probability of unambiguous generation of access key parametres and increased reliability of the system.
