On-line signature verification using Tablet PC
This work addresses secure access and document authentication for Tablet PC users, but it is incremental as it adapts a prior method to a new environment.
The authors adapted an existing online signature verification algorithm for Tablet PCs, evaluating two commercial devices and reporting authentication performance using a new database of over 3000 signatures.
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.
