Patent ID: 7787667

Claim:
A method for finger biometric processing comprising: sensing finger biometric verification data comprising a plurality of pixels using a finger biometric sensor; iteratively selecting, using a processor, a sequence of enrollment spots from finger biometric enrollment data comprising a plurality of pixels representing finger ridge data; selecting, using the processor, at least one verification spot from the finger biometric verification data comprising a plurality of pixels by generating information content data from the finger biometric enrollment data by generating curvature data based upon the finger ridge data, determining at least one peak in the curvature data, and selecting the at least one enrollment spot from the finger biometric enrollment data based upon the at least one peak in the curvature data; determining, using the processor, at least one spot property for at least one of the sequence enrollment spots and the at least one verification spot; comparing, using the processor, at least one of the sequence of enrollment spots with the at least one verification spot based upon a function of corresponding pixel values of at least one of the sequence of enrollment spots and the at least one verification spot, and also based upon the at least one spot property; defining, using the processor, forbidden regions surrounding the sequence of enrollment spots based upon the curvature data; and selecting, using the processor, subsequent enrollment spots based upon the forbidden regions surrounding prior enrollment spots.
