  The pharmaceutical manufacturing faces critical challenges due to the global
threat of counterfeit drugs. This paper proposes a new approach of protected QR
codes to secure unique product information for safeguarding the pharmaceutical
supply chain. The proposed solution integrates secure QR code generation and
encrypted data transmission to establish a comprehensive anti-counterfeit
ecosystem. The protected QR codes encapsulate product information that cannot
be identified using traditional QR code scanners which protect the information
against replication and tampering. The system is developed with scalability in
mind, which can be easily implemented without introducing any additional
modification in the traditional supply chain.
