Abstract:
Provided is a handwritten signature authentication system and method in which handwritten signature authentication is performed by conducting at least one of the following comparisons: a comparison between a pre-enrolled handwritten signature image and a tracked handwritten signature image traced during the signing process, a comparison between a pre-enrolled handwritten signature behavioral characteristics and a handwritten signature behavioral characteristics collected during the signing process, and a comparison between a pre-enrolled handwritten signature image and a reconstructed handwritten signature image regenerated by the handwritten signature behavioral characteristics collected during the signing process.

Claim (Index 3):
The system of  claim 2 , wherein the handwritten signature authentication unit includes:\n a handwritten signature tracking unit detecting and outputting the position data included in the touch data of the handwritten signature input data entered from the handwritten signature input unit; a handwritten signature image acquisition unit acquiring a tracked handwritten signature image from the scan data and the position data where the scan data is entered from the scan unit and the position data is entered from the handwritten signature tracking unit, storing the handwritten signature image acquired in the first level image enrollment unit when the handwritten signature is enrolled, and outputting the tracked handwritten signature image; a handwritten signature behavioral characteristics acquisition unit collecting, from the touch data, the handwritten signature behavioral characteristics data generated by the user's behavioral characteristics according to the handwritten signature; an image reconstruction unit reconstructing the handwritten signature image by the tracked handwritten signature image and the handwritten signature behavioral characteristics data; and a comparison unit comparing the reconstructed handwritten signature image with the enrolled handwritten signature image to determine whether the reconstructed handwritten signature image and the enrolled handwritten signature image are matched when the handwritten signature is enrolled, storing the tracked handwritten signature image in the first level image enrollment unit when it is determined that the reconstructed handwritten signature image and the enrolled handwritten signature image are matched, storing the handwritten signature behavioral characteristics data with respect to the matched handwritten signature in the first level behavioral characteristics enrollment unit, performing the authentication by comparing the reconstructed handwritten signature image with the handwritten signature image enrolled in the first level image enrollment unit, storing the reconstructed handwritten signature image in the second level image enrollment unit when the authentication is successful, and storing the handwritten signature behavioral characteristics data in the second level behavioral characteristics enrollment unit when the authentication is successful.
