Biometric Keystroke Security Vault

Abstract

This project proposes a high-security vault system that authenticates users not just by a 4-digit PIN, but by their unique typing rhythm. An Arduino captures exact millisecond keystroke timing data (dwell and flight times) from a physical keypad and sends it to a PC. An x86 Assembly program acts as the security engine, utilizing the Floating-Point Unit (FPU) to calculate the statistical variance of the typing rhythm. If the biometric profile math matches the owner's stored profile, the Assembly code sends a signal back to the Arduino to disengage the lock.
