Investigating the Effect of Writer Style, Age and Gender on Natural Revocability Analysis in Handwritten Signature Biometric

Abstract

“Natural revocability” is an extremely simple and intuitive strategy for the revocation process in the event of compromise without the need for complex mathematical processing, This paper investigates the possibilities of adopting the strategy, in relation to security and reliability in handwritten signature analysis by exploring the effect of writer style, age and gender on signature analysis. This is examined by performing analysis of variance for the extracted features based on three style categories, two gender groups and three age groups. The results from the analysis provide some valuable insight into the concept of natural revocability as a function of writer style, age and gender.
