Analysis of Presentation Attacks Detection in Signature Biometrics

Abstract

Authentication of biometric methods using various applications such as face or fingerprint recognition have received a lot of interest recently. However, at the same time these biometric systems have been facing different types of attacks. The current work carries out an analysis of different Presentation Attack (PA) scenarios for on-line handwritten signature verification. The present work introduces a short summery of methods for Presentation Attack Detection (PAD) in signature biometrics in order to describe the different levels of PAs existing in on-line signature verification regarding the amount of information available to the attacker, as well as the training, effort and ability to perform the forgeries. This work is an effort towards security evaluation of biometric systems, where attacks are rated depending on expertise of the attacker, as well as the information available and used from the target being attacked.
