December 18, 2006. Estimated Expiration Date is calculated based on simple USPTO term provisions. It does not account for terminal disclaimers, term adjustments, failure to pay maintenance fees, or other factors which might affect the term of a patent.Patent References 3200701 Electro-optical method and apparatus for making identifications Real time fingerprint recording terminal Pattern recognition apparatus Automatic pattern processing system Identification system Fingerprint-based access control and identification apparatus Apparatus and method of personal identification by fingerprint comparison Device for extracting a density as one of pattern features for each feature point of a streaked pattern Finger identification InventorAssigneeApplicationNo. 07/002402 filed on 12/18/1986US Classes:382/127, With a prism382/272Based on a local average, mean, or medianExaminersPrimary: Boudreau, Leo H.Attorney, Agent or FirmInternational ClassesG07C 9/00 (20060101)G06K 9/00 (20060101) Foreign Application Priority Data1985-04-22 GBAbstractA method of authenticating a person by comparing information from a currently taken skin-pattern with stored information from a previously taken skin-pattern is characterized in that the currently taken skin-pattern is produced on a contact surface, an image of the print of the skin pattern on the contact surface is projected onto a photo-detector device (20), the intensity variations of the print image in at least one region thereof impinging on the photo-detector device is assessed in digital form in a multiplicity of different sub-regions of the or each said region to create (in unit 21) a first digital signal train, a second digital train is derived from the stored skin pattern information (in store 23) and the first and second signal trains are compared (in 24) to determine the degree of coincidence therebetween, an assessment of the determined degree being used to decide (on indicator 27) whether the currently-taken and stored skin patterns are sufficiently similar to authenticate the person.Other References
