AI-DRIVEN SMART DOOR SECURITY SYSTEM: AN INTEGRATED APPROACH USING BIOMETRIC AUTHENTICATION AND IOT-BASED ACCESS CONTROL

With the rise in security threats, conventional door-locking mechanisms are no longer sufficient to ensure safety. The Smart Door Security System integrates biometric authentication, IoT-enabled access control, and AI-powered surveillance to enhance security for homes and businesses. This system employs fingerprint recognition, RFID access, facial recognition, and password-based authentication to restrict unauthorized entry. Additionally, IoT connectivity enables remote monitoring and real-time alerts through mobile applications, allowing users to manage access even from remote locations. AI-based algorithms enhance motion detection, anomaly recognition, and automatic response mechanisms, further strengthening security measures.The system also incorporates power backup solutions and encrypted communication to prevent security breaches due to cyberattacks or power failures. Compared to traditional lock-and-key systems, smart security solutions provide enhanced convenience, increased safety, and better access control management. However, challenges such as system reliability, cost-effectiveness, and privacy concerns need to be addressed for wider adoption. Future advancements may include blockchain-based access management, adaptive AI security algorithms, and enhanced biometric sensors. This paper presents a comprehensive overview of smart door security technologies, their implementation challenges, and potential future developments aimed at improving overall security and convenience.
