ABSTRACT:
A method and apparatus for verification of personnel identity by correlation of fingerprint images. The method includes the steps of: first enrolling a person by the steps of forming a reference image of a fingerprint of the person, identifying a plurality of reference sections within the reference image, where the image data contained in each of the reference sections is distinct relative to the image data adjacent to and surrounding the reference section, and saving the image data of each of the reference sections; and then verifying the identity of someone claiming to be an enrolled person by the steps of retrieving the image data of the reference sections of the enrolled person, forming a verify image of the fingerprint of the person claiming to be enrolled, where the verify image includes a plurality of verify regions each corresponding in position to one of the reference sections and each larger in extent than its corresponding reference section, determining a best-match location within each verify region at which the image data is most similar to the image data of its corresponding reference section, and verifying the identity of the person claiming to be enrolled according to the degree of similarity between the image data of the best-match locations and the corresponding reference sections and according to the degree of similarity between the relative positioning of the best-match locations and the corresponding reference sections.
