Abstract
A method and apparatus for determining whether a newly-signed signature and a previously recorded signature were made by the same person. The method and apparatus include the steps of and apparatus for scanning a document containing the newly-signed signature to provide an electrical signal representative of the reflectivity of the newly-signed signature and the document and generating a signature envelope from the electrical signal with the envelope being formed of selected points on the signature. A plurality of characteristics of the newly-signed signature are then calculated based on the location and magnitude of the selected points forming the signature envelope with respect to a reference line. The calculated characteristics of the newly-signed signature are then compared with corresponding characteristics of a standard signature formed from a group of previously recorded signatures and a signature verification decision is generated based on the degree with which the compared characteristics match.
