Pen-based interfaces on mobile platforms give nowadays another possible applicative context for signature verification algorithms. In the previous competitions, the First International Signature Verification Competition (SVC’2004) and the BioSecure Multimodal Evaluation Campaign (BMEC’2007), data came from a single sensor in each case : a digitizing tablet at SVC’2004 (although 2 tasks with different parameters were tested) and a Personal Digital Assistant at BMEC’2007. Also, in both cases performance was evaluated globally on all the persons of the database independently of any quality measured on the data. Finally the impact of temporal variability was not studied in both cases. |
