Counterfeit currency poses a major threat to financial stability across countries such as India, the United States, and Europe. Traditional verification methods are often unreliable because modern counterfeit notes closely replicate genuine banknote features, making manual inspection difficult and error-prone. This paper presents Currency Authenticator AI, an automated multi-currency counterfeit detection system that analyzes banknote images captured through a webcam or uploaded by the user. The proposed model utilizes a hybrid pipeline that combines classical image-processing techniques with a Convolutional Neural Network (CNN) to examine key security elements including microtext, watermark intensity, serial number format, color patterns, security threads, and hologram regions. The system provides both a real/fake prediction and a detailed, feature-level explanation of the results. Experimental evaluation on multiple international currencies demonstrates strong accuracy and consistent performance under varied lighting and capture conditions. The system’s real-time capability and user-friendly interface make it practical for everyday use in banks, retail environments, and public verification platforms. Overall, the study highlights the effectiveness of integrating AI-driven models for reliable and accessible counterfeit currency authentication.
