Abstract:
Provided is a user authentication method and apparatus that obtains first environmental information indicating an environmental condition in which an input image of a user is captured, extracts a first feature vector from the input image, selects a second feature vector including second environmental information that matches the first environmental information from enrolled feature vectors in an enrollment database (DB), and authenticates the user based on the first feature vector and the second feature vector.

Claim (Index 26):
A user authentication apparatus, comprising:\n a sensor configured to acquire an input image of a user; a memory comprising an enrollment database (DB) configured to store feature vectors enrolled with respect to each of items of biometric data; and a processor configured to extract the items of biometric data from the input image, extract a first feature vector corresponding to each of the items of biometric data, obtain environmental information indicating an environmental condition in which the items of biometric data are obtained, select, with respect to each of the items of biometric data, a second feature vector including at least one environmental element that matches the environmental information from the enrolled feature vectors, and authenticate the user based on the first feature vector and the second feature vector corresponding to each of the items of biometric data.
