This project introduces an advanced counterfeit currency detection system that is a combination of explainable deep learning technologies with practical implementation potential. Based on a Convolutional Neural Network (CNN) rooted in the Inception v3 architecture, the system deeply analyzes complex features like textures, patterns, and security marks to identify authentic notes and counterfeits accurately. The Inception v3 model's enhanced feature extraction ability provides high accuracy in the detection of even advanced forgeries. For increased transparency and trust in decision-making, the system integrates explainability tools like SHAP and Grad-CAM that visually highlight important features affecting predictions. Designed for real-time use, the detection system is made available through web and mobile interfaces, thereby ensuring scalability and efficiency for security agencies and financial institutions. By reducing dependency on human-verifiable methods prone to human error and inefficiency, this solution offers a quicker and more reliable method for detecting counterfeits. With adaptive learning capabilities to combat the dynamic nature of forgery methods, the system provides resilience in dynamic environments. Overall, this implementation best bridges the gap between state-of-the-art technology and operational feasibility, thereby offering a powerful tool to combat economic fraud on a large scale.
