Signature Steganography

Abstract

Handwriting signatures captured electronic signing pads are getting wider popularity. The unauthorized used of a signature, such as copying it into an unauthorized payment, is becoming a big concern. Therefore, this paper presents data hiding model as an alternative to the cryptographic authentication approach. This model hides secret signature data inside monochrome cover signature image, depending on gray scale levels of pixel values.The performance of the proposed model has been successfully tested by computer simulation and the results are presented both quantitavely and qualitatively. Robustness tests have been applied to the proposed model according to test methodology.
