SYSTEM AND METHOD FOR USER AUTHENTICATION BASED ON ODOR RECOGNITION
First Claim
1. A system for a user authentication based on odor recognition, comprising:
- an odor sensor unit for sensing an odor of a user'"'"'s body to generate an odor biometric information vector;
a learning unit for performing an initial learning using the odor biometric information vector to generate a comparative odor biometric information vector; and
an authentication unit for performing the user authentication by comparing a odor biometric information vector of the user'"'"'s body to be authenticated from the odor sensor unit with the comparative biometric information vector if the user authentication is required.

Abstract
A system for a user authentication includes an odor sensor unit for sensing an odor of a user'"'"'s body to generate an odor biometric information vector, and a learning unit for performing an initial learning using the odor biometric information vector to generate a comparative odor biometric information vector. An authentication unit performs the user authentication by comparing an odor biometric information vector of the user'"'"'s body to be authenticated from the odor sensor unit with the comparative biometric information vector if the user authentication is required. The authentication unit further performs an incremental learning of the comparative odor biometric information vector using the odor biometric information vector used in the authentication to create an incrementally learned odor biometric information vector. The comparative odor biometric information vector is updated with the incrementally learned odor biometric information vector.

12. A method for a user authentication based on odor recognition, comprising the steps of:
-
(a) sensing an odor of a user'"'"'s body to generate an odor biometric information vector; (b) performing an initial learning using the odor biometric information vector to generate a comparative odor biometric information vector; (c) performing user authentication by comparing an odor biometric information vector of a user to be authenticated with the comparative odor biometric information vector if the user authentication is required; and (d) performing an incremental learning using the comparative odor biometric information vector and the odor biometric information vector used in the user authentication to update the comparative odor biometric information with an incrementally learned odor biometric information vector through the incremental learning. - View Dependent Claims (13, 14, 15)
