RANDOMIZED MULTI-FINGERPRINT AUTHENTICATION

Some disclosed methods involve randomly or pseudo-randomly selecting one fingerprint authentication case from a plurality of fingerprint authentication cases stored in a memory, each of the fingerprint authentication cases corresponding to one or more fingerprints used during an authentication process, the fingerprint authentication cases including a plurality of multiple-fingerprint authentication cases for which two or more fingerprints are used during the authentication process. Upon determining that the selected fingerprint authentication case is a multiple-fingerprint authentication case, some methods involve controlling a display system to provide a multiple-fingerprint authentication graphical user interface (GUI) indicating at least two digit placement areas corresponding with a fingerprint sensor system area of a fingerprint sensor system, controlling the fingerprint sensor system to obtain fingerprint sensor data corresponding to each of the at least two digit placement areas and performing the authentication process based, at least in part, on the fingerprint sensor data.
