TLDR
Experiments on a database containing a total of 1232 signatures of 102 individuals show that writer-dependent thresholds yield better results than using a common threshold.About:

Identity authentication using improved online signature verification method
TL;DR: This work presents a system for online handwritten signature verification, approaching the problem as a two-class pattern recognition problem, and received the first place at SVC2004 with a 2.8% error rate.

Reliable online human signature verification systems
TL;DR: In this paper, a database of more than 10,000 signatures in (x(t), y(t))-form was acquired using a graphics tablet and a 42-parameter feature set was extracted at first, and advanced to a set of 49 normalized features that tolerate inconsistencies in genuine signatures while retaining the power to discriminate against forgeries.

Automatic on-line signature verification
TL;DR: This work proposes a robust, reliable, and elastic local-shape-based model for handwritten on-line curves, and suggests the weighted and biased harmonic mean as a graceful mechanism of combining errors from multiple models.

On-line signature verification with hidden Markov models
TL;DR: It is shown that the amount of dynamic information available to an imposter is important and that forgeries based on paper copies are easier to detect.
