A method for recognizing a person by identification codes derivable from biometric data includes registering a user, and recognizing a registered user, among registered users, through a recognition event. Each user registration event acquires user biometric data, encodes the data into a respective user's registration identification code, associates the code to the user, and registers the user and the associated code. Each recognition terminal is associated to a respective comparison set, including comparison identification codes corresponding to a registered user's identification code. Comparison identification codes are based on comparison between registered users' localization information and known localization of the recognition terminal. A user is recognized among registered users by a recognition event at a terminal. Each recognition event acquires biometric data from the user, which is encoded. The recognition identification code is compared with each of the comparison identification codes. Recognition is recognized or refused based on estimated matching levels. |

1. A method of registration and quick recognition of a user of a service, through identification codes derivable from biometric data, by at least one recognition terminal, having a respective known localization, the method comprising the steps of:
a. registering a user, through a respective registration event comprising:
acquiring from the user to be registered at least one biometric datum;encoding, by a coding procedure, the at least one acquired biometric datum into a respective registration identification code;associating the registration identification code to the user to be registered;registering the user as a registered user, and the associated registration identification code as a registration identification code of the registered user; b. preparing and associating to each of the at least one recognition terminal a respective comparison set, comprising a plurality of comparison identification codes, each of the plurality of comparison identification codes corresponding to a registration identification code of a respective user registered in a previous registration event; c. recognizing a registered user, among a plurality of registered users, by one of the at least one recognition terminal through a respective recognition event, comprising:
acquiring from the user to be recognized said at least one biometric datum;encoding, by said coding procedure, the at least one acquired biometric datum into a respective recognition identification code of the user to be recognized;comparing the recognition identification code with each of the comparison identification codes of the comparison set associated to said one of the at least one recognition terminal;estimating, for each comparison, a respective matching level;recognizing or refusing recognition of the user to be recognized based on the estimated matching levels; wherein the step of preparing and associating comprises:
selecting the plurality of comparison identification codes, among the registered identification codes, for each of the at least one recognition terminal, based on a comparison between localization information of the registered user and the known localization of the recognition terminal. |
