Signature Verification on Handheld Devices

Signature verification for handheld devices (e.g. smartphones, PDAs, etc.) as an authentication method is studied. Signature can be used to authenticate users in mobile networks for secure transactions. The challenges of signature verification on mobile devices are addressed and analyzed and the architecture for a verification platform is outlined. The authors propose a verification system adapted to handheld devices and study its performance. Results are given for the scenarios of casual and skilled impostors using a sub-corpus of the BIOSECURE multimodal biometric database.
