Title:
SIGNATURE VERIFICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/026415
Kind Code:
A1
Abstract:
An objective of the present invention is to improve precision in verifying an inputted signature of a person against an enrolled signature of the person by evaluating speed correlation as a feature value. Provided is a signature comparison system for verifying signature information inputted via a terminal, said verification being performed on a signature verification server. The signature verification server comprises: an input unit for acquiring signature data inputted via the terminal; an assessment unit for computing, for a plurality of instances of signature information stored in a signature database on the signature verification server, the writing speeds at each point in time of two signatures having a standardized signature length and being chronologically associated vis-à-vis pen-stroke positions; and a feature value computation unit for computing a writing speed correlation over the standardized signature length and computing a correlation range for the writing speeds. If the correlation range is not more than a prescribed threshold value, the assessment unit assesses the two signatures to have been inputted by the same person.
