Abstract
A database stores a number N of biometric data representatives which correspond to a set of characteristics of said biometric data. Acquired biometric data is obtained. Then, transformed biometric data is obtained by transforming the acquired biometric data according to said set of characteristics. Next, N deviation values are obtained by applying a comparison between the transformed biometric data and the N representatives in the database. Finally, a vector representing the acquired biometric data is obtained, the representation vector having a number of components less than or equal to N, said components being determined in relation to said N deviation values.
