Automatic Signature Verification (ASV)

Algorithmic systems that compare a questioned signature against a reference set using extracted biometric features (stroke curvature, velocity profile, pressure distribution). Designed against skilled human forgeries; GAN-generated forgeries may defeat ASV by optimising against the same feature distributions.
