Abstract

This paper presents a comparison of pressure of signatures acquired from a digitizing tablet using an inking pen. The written signature is digitized with a scanner and a pseudo pressure is evaluated. The experiments have shown that the obtained histograms are very similar and the two modalities could be used for pressure evaluation. Also, the data from the scanned image proved to be more stable which justifies its use for signature authentication.
