Abstract:
Provided is a segment-block-based handwritten signature authentication system and a method thereof, and more particularly, to a handwritten signature authentication system and a method thereof that enrolls a handwritten signature including handwritten signature characteristics information based on segment blocks disjointed by a user, acquires segment-block-based handwritten signature characteristics information from the handwritten signature upon request for handwritten signature authentication, and performs handwritten signature authentication by comparing the pre-enrolled handwritten signature characteristics information based on segments and the acquired handwritten signature characteristics information.

Claim (Index 1):
A segment-block-based handwritten signature authentication system, the system comprising:\n a handwritten signature input unit that includes a touch input unit that outputs touch data, as a handwritten signature input data, including position data and pressure data with respect to positions that are touched by a signer for handwritten signature; an enrollment unit that enrolls handwritten signature characteristics information of each signer; and a handwritten signature authentication unit that generates a handwritten signature image and segment images by identifying a handwritten signature of the signer and recognizing segments disjointed by the signer from the handwritten signature input data entered from the handwritten signature input unit, generates both a handwritten signature block including the handwritten signature and segment blocks containing the segments, collects handwritten signature characteristics information (\u03a3) including each segment block information, handwritten signature block information, correlation information between the segment blocks, and correlation information between each segment block and the handwritten signature block, maps the collected handwritten signature characteristics information to identification information of the signer, enrolls the collected handwritten signature characteristics information in the enrollment unit, collects handwritten signature characteristics information (\u03a3) including correlation information between the segment blocks and correlation information between each segment block and the handwritten signature block from the touch data entered through the touch input unit of the handwritten signature input unit upon request for handwritten signature authentication, loads the enrolled handwritten signature characteristics information (\u03a3\u2032) that corresponds with the identification information of the signer who requests handwritten signature authentication, and performs a segment-block-based handwritten signature authentication according to a match rate by comparing the enrolled handwritten signature characteristics information (\u03a3\u2032) with the collected handwritten signature characteristics information (\u03a3).
