On-line signature verification using Tablet PC

TL;DR

This paper adapts an on-line signature verification algorithm for Tablet PC devices, evaluating its performance with real signatures and forgeries, and demonstrates its application in secure access and document protection.

Contribution

It presents an adaptation of a signature verification algorithm specifically for Tablet PCs and evaluates its effectiveness with a new signature database.

Findings

High accuracy in distinguishing genuine signatures from forgeries

Effective performance across different Tablet PC models

Feasibility of using signature verification for security applications

Abstract

On-line signature verification for Tablet PC devices is studied. The on-line signature verification algorithm presented by the authors at the First International Signature Verification Competition (SVC 2004) is adapted to work in Tablet PC environments. An example prototype of securing access and securing document application using this Tablet PC system is also reported. Two different commercial Tablet PCs are evaluated, including information of interest for signature verification systems such as sampling and pressure statistics. Authentication performance experiments are reported considering both random and skilled forgeries by using a new database with over 3000 signatures.
