Abstract
A method for evaluating an individual fingerprint template by using a remote dataset, comprising the steps of capturing a fingerprint representation by a fingerprint reader on a device, extracting significant data from the captured fingerprint representation, thereby creating an individual fingerprint template for the captured fingerprint representation, transmitting the individual fingerprint template from the device to a remote dataset comprising a plurality of fingerprint templates, determining an impostor score distribution for the individual fingerprint template, determining a security threshold for the individual fingerprint template, and transmitting the determined security threshold to the device. The advantage of the invention is that an individual security threshold can be set for a user, which will improve the FAR distribution of a device.
