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 6):
The system of  claim 3 , wherein the overall handwritten signature block characteristics detection unit further generates and outputs the overall handwritten signature block space information (SPACE S ) by calculating space area of the handwritten signature block (S) and wherein the segment block correlation detection unit comprises:\n an intersection space detection unit that detects any adjacent segment block (s j ) having a relation of inclusion or intersection with each segment block (s i ), and outputs, if any, intersection space information (\u03b4 ij ) by calculating space area of inclusion or intersection; an intersection space ratio detection unit that receives the overall handwritten signature block space information (SPACE S ), the segment block space information (space s i ), and the intersection space information (\u03b4 ij ) as input, generates handwritten signature block intersection space ratio information (r ij ) by calculating a ratio of the intersection space (\u03b4 ij ) against the overall handwritten signature block space (SPACE S ), generates segment block intersection space ratio information (\u03c1\u2032 ij ) by calculating a ratio of the intersection space (\u03b4 ij ) against the segment block space (space s i ), and generates adjacent segment block intersection space ratio information (\u03c0\u2033 ij ) by calculating a ratio of the intersection space (\u03b4 ij ) against the adjacent segment block space (SPACEs j ); a segment block inclusion relation detection unit that generates and outputs segment block inclusion relation information (O ij ), which shows whether an adjacent segment block (s j ) is included in or intersects with a segment block (s i ); a segment positional relation detection unit that generates and outputs segment block positional relation information (POS ij ) representing relative position on all adjacent segment blocks (s j ) based on a segment block (s i ); an edge positional relation detection unit that generates and outputs segment block edge positional relation information (EDGE ij ) representing relative edge position at which edge of a segment block (s i ) intersects with all adjacent segment blocks (s j ); and a correlation characteristics information generation unit that generates and outputs block correlation characteristics information (C) including the intersection space information (\u03b4 ij ), the handwritten signature block intersection space ratio information (r ij ), the segment block intersection space ratio information (\u03c0\u2032 ij ), the adjacent segment block intersection space ratio information (\u03c0\u2033 ij ), the segment block inclusion relation information (O ij ), the segment block positional relation information (POS ij ), and the segment block edge positional relation information (EDGE ij ).
