Abstract

A method quickly recognizes a person by identification codes derivable from biometric data and includes registering a user, and recognizing a registered user, out of multiple registered users, through a recognition event. Each registration event includes acquiring biometric data of the user; then, encoding the biometric data into a respective registration identification code associated with the user; and registering the user and the associated registration identification code. Each recognition event includes acquiring the biometric data; then, encoding the biometric data into a respective recognition identification. Based on said registered registration identification codes, a comparison set of comparison identification codes is prepared. The recognition identification code is compared with each comparison identification code; and for each comparison, a respective matching level is estimated. The user is recognized or refused recognition based on the estimated matching levels. Each comparison includes a processing operation carried out by applying a trained algorithm.

Claims28

Dependent claims

A method of registration and recognition of a user of a service, through identification codes derivable from biometric data, comprising the steps of:

a. registering a user, through a respective registration event, wherein each registration event comprises:
acquiring from the user to be registered at least one biometric datum of the user;
encoding, by a coding procedure, the at least one acquired biometric datum into a respective registration identification code of the user to be registered;
associating said registration identification code to the user to be registered;
registering the user as a registered user, and the associated registration identification code as the registration identification code of the registered user;
b. recognizing a registered user, among a plurality of registered users, through a respective recognition event, comprising:
acquiring from the user to be recognized said at least one biometric datum of the user;
encoding, by said coding procedure, the at least one acquired biometric datum into a respective recognition identification code of the user to be recognized;
preparing, based on the registration identification codes, registered at a plurality of registration events, a comparison set comprising a plurality of comparison identification codes;
comparing the recognition identification code with each of said plurality of comparison identification codes;
estimating, for each of said comparisons, a respective matching level;
recognizing or refusing recognition of the user to be recognized based on the estimated matching levels;
wherein said steps of acquiring comprise acquiring a digital image of a hand of the user by a digital acquisition device;
wherein each of said comparisons between the recognition identification code and one of the comparison identification codes comprises processing carried out by applying at least one trained algorithm,
and wherein the recognition event further comprises the step of further training said at least one trained algorithm.

12 more elements

biometric data acquisition means, configured to acquire at least one biometric datum of the user, said biometric data acquisition means comprising a digital acquisition device cofigured to acquire a digital image of a hand of the user;
first terminal processing means, operatively connected to the biometric data acquisition means, to receive the at least one acquired biometric datum, and configured to encode the at least one acquired biometric datum into a recognition identification code of the user, at a recognition event of the user;
b. storing means, configured to store a plurality of registered registration identification codes;
c. a recognition apparatus, operatively connected to the recognition terminal, to receive the recognition identification code generated by said recognition terminal, and further operatively connected to the storing means to access the registered registration identification codes, said recognition apparatus comprising recognition processing means, configured to:
prepare, based on said registered registration identification codes, a comparison set comprising a plurality of comparison identification codes;
compare the recognition identification code with each of said plurality of comparison identification codes;
estimate, for each of said comparisons, a respective matching level, by processing carried out by applying at least one trained algorithm;
recognizing or refusing recognition of the user to be recognized based on the estimated matching levels;
