Digitization of signatures is described, and features are developed to allow comparisons.
Abstract
Using data reduction techniques, a list of between two and seven values can be obtained to give a coded description of a signature, which can subsequently be used in authentications. Between one and six specimens can give an adequate data base. Thus, it has been possible to achieve rejection of 97 percent of examples of name writing which were not genuine signatures, at thresholds which accepted 90 percent of authentic signatures. The system may provide some support to document examiners in cases of skilled forgery and is of limited value in author identification. (Publisher abstract)
