Description

A method for the automated identification of a fingerprint consists in, first creating a pixel map of the fingerprint. The pixel map is then thinned to ease the finding of the coordinates of the points forming the epidermal ridges of the fingerprint. These epidermal ridges are then tracked and characterized mathematically. The mathematical characterization produces a set of values that can be compared to other sets of values characterizing pre-identified fingerprints and stored in a database. The apparatus adapted to carry out the method includes an input device to create a pixel map of a fingertip, a controller to execute all the computations on the pixel map and a storage device to store the resulting values characterizing the epidermal ridges on the fingertip.
