Enhancement of DTW algorithm in on-line signature mapping using the lost-box recovery algorithm

الملخص EN

Signature is a common practice as a way of identifies authentication or verification.

Signature On-line validation and authentication is a field of authenticating the time series signature data which is generally acquired from the tablet-based device.

Different from common traditional signature image, the on-line signature image data contain number of points that are arranged in sequence of time.

The aim of this research is to enhance existing approach to map the strokes in both test and reference signatures.

Current methods make use of the DTW (Dynamic Time Warping) algorithm and its deviate to segment them before comparing each of its data dimension.

This study suggesting a modified DTW algorithm with the proposed Missed Nodes Recovery Algorithm aims to improve the mapping performance.
