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 4):
The system of  claim 3 , wherein the overall handwritten signature block characteristics detection unit further generates and outputs overall handwritten signature block space information (SPACE S ) by calculating space area of the handwritten signature block (S), and wherein the segment block characteristics detection unit comprises:\n a segment block generation unit that receives the segment images as input, and generates and outputs the segment block (s i ) including the corresponding segment image; a segment block edge position detection unit that receives the segment block (s i ) as input, and detects and outputs segment block position information (p i ), which is information on all edges of the segment block; a segment block space characteristics detection unit that receives at least one of the segment block (s i ) and the segment block position information (p i ), and generates and outputs segment block space information (space s i ) by calculating the space area of the segment block (s i ); a space ratio characteristics detection unit that receives the overall handwritten signature block space information (SPACE S ) and the segment block space information (space s i ) from the overall handwritten signature block characteristics detection unit, and generates and outputs segment block space ratio information (\u0394 i ) by calculating a ratio of the space area of the segment block against the overall handwritten signature block space; and a segment block characteristics information generation unit that generates, for each segment of handwritten signature, the segment block characteristics information (v i ) including the segment block position information (p i ), the segment block space information (space s i ), and the segment block space ratio information (\u0394 i ), and generates and outputs the overall segment block characteristics information (V) on all segments of the entire handwritten signature.
