Fractals in person’s signature

Abstract

Signature is a very simple material as it is both a copy of model as well as the result of very complex biological
mechanisms. The domain of the signature showing interest of a study relaying of Fractal Principal. The fractal behavior of
different person’s signature can be justified by different methods of Fractal dimension such as Divider Step Method (DD)
and Box Counting Method (DB).It attempt to justify the Fractal behavior and Fractal dimension used here, and introduced
some application of our study in the medical field such as DNA finger printing, signature recognition or authentication.
