A method of fingerprint enrolment or registration comprises: obtaining a first fingerprint view or image (12-16) without prompting a user to position a finger 10 for sensing; creating a single record containing the obtained fingerprint view; and determining whether the record of the obtained fingerprint view reaches a target threshold value. Subsequent views obtained at later times (12-16) may be added to the record, for example if the threshold was not initially reached. A complete record of the fingerprint can thus be built up over time (50). The fingerprint views may be obtained by associating a fingerprint sensor 140 with the on/off button 125 of a device. The methods and system disclosed are easier to use and avoid the inconvenience of following an enrolment procedure. Independent claims are provided for an authentication method based on the enrolled fingerprints. |
