Online Payment Security Using Image Cryptography

Abstract

In the 21st Century, the digital payment is increasing day by day and the traditional methods of digital
payment are losing its authenticity. Due to recent intrusions and attacks on the payment system making it vulnerable,
whether the old systems are still robust is debatable. This paper presents a novel method of digital payment using image
cryptography and watermarking techniques. The proposed system ensures a more robust and simple system for
electronic payments. To achieve this, the system uses a binary image, called watermark, is split into two shares via a 2-
out-of-2 visual secret sharing scheme. Then, one of the share is embedded into the host image, and the other is held by
the owner. When proving the ownership, the owner has to extract the embedded share and recover the watermark with
his/her own share. Based on the security property of visual cryptography, the proposed system can make sure that the
two shares cannot leak any information about the watermark. Proposed Online Payment system is a software based and
is universally compatible with all systems.
