Enhancing Security and Flexibility in Smart Locker Systems: A Multi-Authentication Approach with IoT Integration

The past decade has witnessed the widespread integration of the Internet of Things (IoT) in the evolution of smart locker systems. However, many existing systems rely on a single authentication method, limiting their adaptability. These systems fail to account for potential unavailability of the chosen authentication method due to issues such as lost access cards, damaged cameras, or malfunctioning devices. Furthermore, the vulnerability of relying on a single authentication method, without considering dual-authentication approaches, poses a security risk, as unauthorized access could occur through eavesdropping or code interception. This paper addresses these shortcomings by introducing a smart locker system that incorporates multiple authentication methods, including dual authentication (utilizing both phone number and One Time Password (OTP)), fingerprint recognition, face recognition, and emergency code. Leveraging IoT technology, the system offers a range of authorization methods to grant access permission. The dual authentication method serves as the foundational security layer, significantly enhancing the locker’s overall security. The system is developed, implemented, and rigorously evaluated under various scenarios. The outcomes demonstrate superior performance compared to existing systems, particularly in terms of accuracy and flexibility.
