Sätt och anordning för att bearbeta biometriska data, särdrag känns av och data klassas efter dessa särdrag

摘要

There is a large number of data dots (32) in a three-dimensional space (31), which is divided into subspaces (33) based on the number of dots so that each subspace preferably contains the same number of dots. Subsequently, a typical or attraction point (34) is assigned to each subspace so that the dots in this space are closer to it than to attraction points in other subspaces. A subspace for the current biometric data is selected by determining the distance between the corresponding current data spot (35) and the attraction point and the subspace is selected whose attraction point is positioned at the shortest distance from the current data spot. Independent claims are included for a method and device for generating reference data from current biometric data, for a method of checking right of access and for a biometric data processing unit.
