Abstract :
A high-resolution graphics tablet was used to obtain X, Y, and Z pressure samples of signatures from 20 people. These are serving as the initial database for a study to determine if a fast, reliable procedure can be devised for computer verification of a person´s signature written on such a tablet. The authors discuss some of the dynamic features of the signature data and their possible uses in augmenting the shape analysis of signatures in the verification task. These features include duration, speed, centripetal and tangential acceleration. A first stage verification procedure is proposed for rapid screening of signatures prior to the complete shape analysis
