DESIGN AND IMPLEMENTATION OF A SECURE QR PAYMENT SYSTEM

Abstract

It is used to describe the design and implementation of a secure payment system based on QR codes. These QR codes have been extensively used in recent years since they speed up the payment process and provide users with ultimate convenience. However, as convenient as they may sound, QR-based online payment systems are vulnerable to different types of attacks. Therefore, transaction processing needs to be secure enough to protect the integrity and confidentiality of every payment process. Moreover, the online payment system must provide authenticity for both the sender and receiver of each transaction. In this paper, the security of the proposed QR-based system is provided using visual cryptography. The proposed system consists of a web application that implements visual cryptography. The application provides a simple and user-friendly interface for users to share links through QR Code. Keywords— Cryptography, decrypt, encrypt, QR Code, Visualization
