Authors - Sharim Iqbal, Purnima Ahirao, Deepti Patole Abstract - QR code payment systems have become increasingly popular thanks to their speed, simplicity, and convenience. However, as their usage grows, so do concerns around security—issues like tampering, spoofing, and man-in-the-middle attacks are becoming more common. To address these vulnerabilities, this paper introduces a novel approach to securing QR-based transactions using visual cryptography. Visual cryptography works by splitting an image into multiple shares, which individually reveal nothing but can reconstruct the original image when overlaid—without the need for complex decryption algorithms. This research proposes a secure QR payment system that leverages visual cryptography to enhance data integrity, prevent fraud, and strengthen the overall security of mobile payments. The study covers current security challenges, outlines the proposed system architecture, implementation details, and evaluates its performance.
