Abstract : In this paper we discuss automatic signature verification in the context of the graphology. Graphology is claimed to be useful for everything from understanding health issues, morality and past experiences to hidden talents, and mental problems. It is not restricted to this, though. Forensic document examiners use the concepts of graphology to examine handwriting in order to detect authenticity or forgery. In this work, we describe some of the main features of the graphology and propose a set of features to automatic signature verification. They are evaluated in a database of 5,600 signatures using hidden Markov models
