Towards mobile authentication using dynamic signature verification: Useful features and performance evaluation

The proliferation of handheld devices such as PDAs and smartphones represents a new scenario for automatic signature verification. Traditionally, research on signature verification has been carried out employing signatures acquired using digitizing tablets or TabletPCs. In this paper we study the effects of the mobile acquisition conditions and we analyze the considerations that must be taken in the new handheld scenario. A signature verification system adapted to handheld devices via feature selection is proposed and a systematic comparison with a traditional pen tablet-based system is performed. The system is combined with another based on Hidden Markov Models using score fusion. Results confirm an increased signature variability in the case of handheld devices.1
