Abstract
A process and apparatus for encoding the ridge endings and bifurcations of an inquiry fingerprint and for automatically searching through a file of similarly encoded fingerprints for the fingerprint(s) whose minutiae are most similar to those of the inquiry fingerprint. The process does not require registration of the minutiae prior to storage or searching and the storage and search of file fingerprint cards can be implemented on a digital computer system since the minutiae data from each print is in a form easily processed by computer.
