Abstract

Document forgery has become a significant challenge in modern digital and physical verification systems due to the widespread availability of image editing tools and duplication techniques. Traditional verification methods rely heavily on manual inspection, which is time-consuming, error-prone, and inefficient.


This project proposes an IoT-based smart document authentication system using QR code verification. The system utilizes an ESP32-CAM module to scan QR codes embedded within documents. The scanned data is decoded and validated against predefined or cloud-based records. Based on the validation result, the system provides real-time feedback using visual and audio indicators. A green LED indicates a valid document, whereas a red LED along with a buzzer alert indicates a forged or invalid document.


The system is designed to be low-cost, scalable, and efficient, making it suitable for applications in educational institutions, banking systems, identity verification, and secure access control environments.
