<p>The invention relates to a system and methods for verifying a person's identity, and pertains in particular to such a system and methods which utilize comparison of a fingerprint pattern for identification verification. The image of a fingerprint of a person to be identified is provided on an inkless means which when touched by finger of the person causes immediate development of an image of the fingerprint of the finger in a black and white appearance. This image of a fingerprint is video scanned (60) to produced image data which is digitized (10) to produce a non-minutiae digitized numerical identifier indicative of the fingerprint. A preferred method and system provides a non-minutiae digitized numerical identifier having 24 bytes of fingerprint identification data which is recordable within the magnetic stripe of a credit card personal to a person, or may be recorded within the confines of a portable personnel identification means, or within a smart card, personal to a person. The non-minutiae digitized numerical identifier is provided by selectively analyzing different parts of a fingerprint and deriving from each part a byte numeric which is directly related to the ridge count computed for that part. Prior to performing the 'digitizing' method, a fingerprint identity window is defined as the area of analysis. The present invention also discloses inventive methods relating to 'image sizing' and 'image framing' which are performed upon the fingerprint image and whitespace digital data stored in memory, prior to defining a fingerprint identity window. Various applications of the invention methods and system are disclosed herein.</p> |
