In a method of preventing false acceptance in a system for checking fingerprints, a latent fingerprint on the sensor () is detected by the location of a currently recorded fingerprint being compared with the location of a previously recorded fingerprint. If the location essentially corresponds, the recorded fingerprint is considered as originating from a latent fingerprint, and the fingerprint is rejected. Otherwise, the fingerprint is considered as originating from an actual finger on the sensor.

Check for fingerprints

A fingerprint identification/verification system using bitmaps of a stored fingerprint to correlate with a bitmap of an input fingerprint, wherein an accurate reference point is located and selected two-dimensional areas in the vicinity of the reference point of the input image of the fingerprint are correlated with stored fingerprint recognition information to determine if the input fingerprint image and the stored fingerprint recognition information are sufficiently similar to identify/verify the input fingerprint.
