1. A method of storing a set of biometric data templates, which emanates from a biometric object, from among a plurality of biometric data templates, wherein each biometric data template includes biometric data from only a part of the biometric object, the method comprising:

  • aligning a plurality of biometric data templates with each other in view of the biometric object of the plurality of biometric data templates, which involves partially overlapping at least one biometric data template of the plurality of biometric data templates with at least one other biometric data template of the plurality of biometric data templates;

    determining the set of biometric data templates to be stored; and

    storing the set of biometric data templates;

    wherein the determining of the set of biometric data templates to be stored involvesassigning 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 includes an amount of cells comprising distinguishable biometric data which fulfil a predetermined criterion.
