1. A computer implemented method for authenticating an identity of a person, the method comprising:
acquiring a sample fingerprint image of a finger of the person;
extracting four sub-portions from the sample fingerprint image forming four fingerprint test images from an upper left portion, an upper right portion, a lower left portion, and a lower right portion of the sample fingerprint image;
independently running a fingerprint recognition on all of the fingerprint test images;
authenticating the identity of the person upon a positive outcome from all of the independently run fingerprint recognitions; and
masking out information in an overlapping region in the fingerprint test images, such that the fingerprint test images are uncorrelated.
