Claim Text:
1. A method for mapping a dynamic chirographic sample to a fixed metric vector space, the method comprising using at least one hardware processor for: providing a dynamic chirographic sample of a target subject, the dynamic chirographic sample of the target subject is a dynamic signature of the subject; providing a reference model for the dynamic chirographic sample, the reference model is a reference signature, the reference signature is an estimated Universal-Background-Signature (UBS), wherein the estimated UBS is estimated by: aligning the dynamic chirographic sample of the target subject to the reference model; and generating a chirographic supervector based on the aligned dynamic chirographic sample of the target subject, wherein the supervector represents features of the dynamic chirographic sample of the target subject mapped in a fixed metric vector space.
