There is provided a method of storing a set of biometric data templates, which emanates from a biometric object, among a plurality of biometric data templates, wherein each biometric data template comprises biometric data from only a part of a biometric object. The method comprises aligning biometric data templates with each other in view of the biometric object of the plurality of biometric data templates which comprises partially overlapping biometric data with at least one other biometric data template; determining the set of biometric data templates to be stored; and storing the set of biometric data templates. The determining of the set of biometric data templates to be stored comprises assigning a matrix of cells covering at least partially the aligned biometric data templates; determining, for each of the aligned biometric data templates, cells comprising distinguishable biometric data; and determining a combination of biometric data templates which comprises an amount of cells comprising distinguishable biometric data which fulfil a predetermined criterion. A method of biometric matching is also disclosed, and also a biometric matching apparatus and a computer program.
