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 2):
The system of  claim 1 , wherein the handwritten signature authentication unit comprises;\n a handwritten signature characteristics extraction unit that extracts the handwritten signature characteristics information (\u03a3) including overall handwritten signature block characteristics information (Q) which is characteristics information of the handwritten signature block that includes the handwritten signature image, overall segment block characteristics information (V) which is characteristics information on the handwritten signature segments that constitute the handwritten signature, and block correlation characteristics information (C) caused by the correlations between the segment blocks and the correlations between each segment block and the handwritten signature block, from the handwritten signature input data entered from the touch input unit of the handwritten signature input unit; a handwritten signature segment block authentication unit that performs handwritten signature authentication according to each predetermined match rate by comparing the handwritten signature characteristics information (\u03a3) extracted from the handwritten signature characteristics extraction unit with the pre-enrolled handwritten signature characteristics information (\u03a3\u2032); and a control unit that saves and enrolls the handwritten signature characteristics information, as extracted through the handwritten signature characteristics extraction unit, to the enrollment unit at time of request for enrollment, and performs handwritten signature authentication by controlling the handwritten signature segment block authentication unit at time of request for handwritten signature authentication.
