This paper presents a new approach to generate biometric hash values based on statistical features in online signature signals. Whilst the output of typical online signature verification systems are threshold-based true-false decisions, based on a comparison between test sample signals and sets of reference signals, our system responds to a signature input(More)
The enrollment phase of signature verification systems is a critical process, in which reference data of a user is acquired, that needs to be of satisfying quality without overloading the subject by asking for too many repetitions. Many signature verification systems do not perform an enrollment quality evaluation at all, or only after capturing a fixed(More)
