SigSA : On-line Handwritten Signature Database

Online signature verification is a challenging problem. It’s difficulty comes from the problem of separation between genuine variation of an individual’s signatures and that of forgery signatures. Different algorithms have been proposed by various researchers, however lack of the publically available signature databases hinders benchmarking their performances. In this paper we introduce a signature database constructed from donations of 110 different signers. We describe acquisition process, hardware used for the acquisition as well as forgery collection. We also assess and report performance of the state of the art online signature verification algorithm using the database. The database will be made available for the academic purposes through http://biometrics. sabanciuniv.edu/sigsa .
