(Medguardai) AI + Blockchain Based Fake Medicine Detection System

Abstract

The increasing circulation of counterfeit and unsafe medicines poses a serious threat to public health worldwide. Traditional verification methods such as manual checks and barcode validation often fail to provide real-time and reliable authentication to end users. This paper presents MedGuardAI, an intelligent medicine verification system that combines image-based scanning, QR code validation, artificial intelligence, and trusted data sources to ensure medicine authenticity and patient safety. The proposed system allows users to scan medicine packaging or upload images through a mobile application to verify authenticity, view confidence scores, and receive safety-related information. Additionally, the system supports disease-based medicine search to assist users with preliminary guidance while emphasizing medical consultation. Experimental evaluation and application results demonstrate that MedGuardAI offers an effective, user-friendly, and scalable solution for counterfeit drug detection and medicine awareness.
