Abstract

The increasing number of protected areas requires reliable methods of access control. Traditionally, computer systems rely on passwords for access security. To avoid unauthorized access, an access control might use biometric features such as fingerprints, irispatterns, voiceprints or signature. This paper presents a system for verifying a personal’s identity by comparing signatures. Signatures are intrinsically more secure than passwords. Their invisible dynamics cannot simply be guessed. A pressure sensitive graphics tablet as the input device records the pen motion during signature and sends signals to a computer. From this data, characteristic parameters like horizontal and vertical trace, velocity and acceleration are determined. Depending on the variation of these values in comparison to reference datasets, the system classifies the signature to be an original or a forgery. A database has been constructed with 400 dynamic signatures to validate chosen features and procedures.
