This research proposal explores the development of a low-cost, high-speed biometric authentication system for secure door access control in workplaces. The project aims to address current limitations in existing biometric systems, such as privacy concerns, processing speed issues, and susceptibility to spoofing attacks. By leveraging advanced techniques like Raspberry Pi, Bloom filters, and multi-stage access levels, the proposed system will enhance accuracy, reduce processing time, and improve overall security. The research will investigate the integration of gesture-based biometrics and RFID technology to create a robust and adaptable solution. The expected outcomes include a seamless real-time access control system with enhanced accuracy, reduced processing time, and improved security through multi-level biometric screens and cryptographic key generation.
