A Literature on Handwritten Signature Extraction Techniques

Abstract

Signature is a special case of handwriting which includes special characters and flourishes. Many signatures can be unreadable. They are a kind of artistic handwriting objects [1]. Often stylized depiction of someone's name, nickname, or other mark that a person writes on documents as a proof of identity and intent, hence it is articulated as a behavioural biometric. Signature is socially accepted and extensively used means for authentication in our daily life. It is widely used to recognize a person delivering out daily procedures for example in bank operations, document analysis, electronic funds transfer and access control. Signature can be handled as an image, and hence, it can be recognized using computer vision. Signature that has been transformed to electronic form can therefore be termed as an electronic signature. Electronic signature capturing is classified into two broad categories namely on-line and off-line. With off-line technique, signature is signed on a piece of paper and scanned to a computer system while in on-line technique, signature is signed on a digitizer and dynamic information like speed, pressure is captured in addition to a static image of signature.
