The paper presents to address this challenge, we have proposed the use of
Adaptive Window Positioning technique which focuses on not just the meaning of
the handwritten signature but also on the individuality of the writer. This
innovative technique divides the handwritten signature into 13 small windows of
size nxn(13x13).This size should be large enough to contain ample information
about the style of the author and small enough to ensure a good identification
performance.The process was tested with a GPDS data set containing 4870
signature samples from 90 different writers by comparing the robust features of
the test signature with that of the user signature using an appropriate
classifier. Experimental results reveal that adaptive window positioning
technique proved to be the efficient and reliable method for accurate signature
feature extraction for the identification of offline handwritten signatures.The
contribution of this technique can be used to detect signatures signed under
emotional duress.Comment: 13 pages, 9 figures, 2 tables, Offline Handwritten Signature, GPDS
