TITLE Secure Boot Authentication in Personal Computers Using Fingerprint Recognition and Hardware-Level Access Control
ABSTRACT This paper proposes a hardware-level biometric authentication system that physically controls the boot process of personal computers. A Raspberry Pi 3B+ interfaces with an R307S fingerprint sensor via UART and controls a 5V relay connected to the ATX motherboard PWR_SW header, preventing boot without fingerprint verification. Fingerprint templates are stored on-device, access logs are encrypted using AES-128 Fernet, and the service auto-starts via systemd. Prototype validation confirms sub-second response times and successful authentication across all defined test cases.
