1. A method of adapting a signature verification system to variations in a signature of a user, comprising the steps of:

  • obtaining one or more signature samples from the user, the one or more obtained signature samples being submitted by the user as part of a regular authentication procedure associated with the signature verification system; and

    updating a reference set of signature samples for the user through selection of one or more signature samples from the obtained signature samples, such that the updated reference set is usable by the signature verification system for verifying subsequent signature samples attributed to the user;

    wherein the selection of the one or more signature samples used to update the reference set is conditioned on a false rejection rate of the user when at least one obtained signature sample of the user is authenticated and on an identification check when no obtained signature sample is authenticated; and

    further wherein the updating step is implemented as one or more software components loaded from a memory and executed by a processor.
