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 3):
The system of  claim 2 , wherein the handwritten signature characteristics extraction unit comprises;\n a handwritten signature start detection unit that detects the start of a handwritten signature from the touch data; a handwritten signature end detection unit that detects the end of a handwritten signature designating a final touch data input point as an end point of the handwritten signature when there is no touch data input for a certain period of time; a segment detection unit that detects the segments disjointed by handwriting the signature from the touch data, and generates and outputs segment images of the detected segments; a segment count unit that counts the number of the segments detected in the segment detection unit; a segment block characteristics detection unit that receives the segment images as input, creates each segment block (s i ) including the corresponding segment image, generates each segment block characteristics information (v i ) on the created segment block (s i ), and generates and outputs overall segment block characteristics information (V) including all of the generated segment block characteristics information (v i ); an overall handwritten signature block characteristics detection unit 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 unit that generates and outputs the block correlation characteristics information (C) according to the correlations between the segment blocks and the correlations between the overall handwritten signature block and each segment block; and a handwritten signature characteristics acquisition unit that includes a handwritten signature block characteristics information generation unit that 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).
