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 10):
The method of  claim 8 , wherein the handwritten signature characteristics information (\u03a3) acquisition step comprises:\n a handwritten signature tracking step that begins tracking the handwritten signature from the touch data of the handwritten signature input data entered from the handwritten signature input unit; a segment detection step that detects handwritten signature segments disjointed by the signer from the touch data through a segment detection unit, and generates and outputs segment images of the detected segments when the handwritten signature tracking step begins; a segment count step that counts the number of the segments detected from the segment detection unit; a segment block characteristics detection step that receives the segment image as input, creates each segment block (s i ) including the corresponding segment image, and generates and outputs each segment block characteristics information (v i ) on the created segment block (s i ); an overall handwritten signature block characteristics detection step that creates a handwritten signature block (S) including the acquired handwritten signature image, and generates and outputs overall handwritten signature block characteristics information (Q) on the handwritten signature block (S); a segment block correlation detection step that generates and outputs block correlation characteristics information (C)\u2014according to the correlations between the segment blocks and the correlations between the overall handwritten signature block and each segment block; and a handwritten signature block characteristics information generation step that generates overall segment block characteristics information (V) including segment block characteristics information (v i ) on all segments, and generates and outputs handwritten signature characteristics information (\u03a3) including the overall handwritten signature block characteristics information (Q), the overall segment block characteristics information (V), and the block correlation characteristics information (C).
