Advanced Security Protocols for Preventing QR Code Hacking

Abstract: The proposed project involves the development of a QR OTP-based authentication system, offering three distinct modes of operation: QR OTP Authentication,QR OTP Authentication with Time, and QR OTP Authentication with Location. The system aims to enhance security by integrating QR code scanning with One-Time Password (OTP) generation, which is verified by a server-side application. A Flask-based web application serves as the backend for displaying the QR code, OTP, and the relevant time or location for the authentication process.The system is designed to improve the overall security of mobile applications, especially in scenarios where enhanced authentication methods are required. The system integrates multiple layers of security: QR code scanning, OTP generation, time-based authentication, and locationbased authentication. The QR OTP Authentication mode works by generating a unique OTP that is encoded into a QR code. The user then scans the QR code using an Android app developed on the Kodular platform, which includes a QR scanner, OTP generator, time checker, and location checker. Once the QR code is scanned, the OTP is extracted and validated. In the timebased authentication mode, the OTP is only valid for a specific time window, adding an additional layer of security. The locationbased authentication mode ensures that the OTP is only valid within a specific geographical location, further enhancing the authentication process.
