Counterfeit Banknote Detection System

  • Abstract:
  • Counterfeit banknotes pose significant economic and security challenges globally. Traditional detection methods, reliant on manual inspection and physical security features, are often inefficient and error-prone. This paper proposes a deep learning-based system leveraging Convolutional Neural Networks (CNNs) to automate fake banknote detection. The system processes high-resolution banknote images through preprocessing, feature extraction, and classification modules. Experimental results demonstrate an accuracy of 98.3% on a dataset of 1,000 images, outperforming traditional methods like UV analysis and KNN classifiers. The solution is scalable, integrable with existing financial infrastructure (e.g., ATMs, POS systems), and robust under diverse environmental conditions. Key contributions include a hybrid CNN architecture combining ResNet and edge detection, a portable edge-computing implementation, and synthetic data augmentation using Generative Adversarial Networks (GANs). The system’s efficacy is validated through metrics such as precision (97.5%), recall (98.1%), and F1-score (97.8%), establishing its applicability in real-world scenarios.
