Abstract

A method of determining whether a test sample belongs to the same individual as a plurality of reference samples. The method includes providing respective values of one or more identifying features from the test sample and the plurality of reference samples, representing the test and reference samples by respective points having coordinates in a multi-dimensional space indicative of the respective feature values, and deciding whether the test sample belongs to the same individual as the plurality of reference samples based on a geometrical property of the points.
