Voice as Your Vault: Exploring an Innovative Audio Password System

Voice as Your Vault: Exploring an Innovative Audio Password System In today's digital world, where cyber threats loom large, traditional passwords often fall short. Enter voice authentication—a blend of biometrics and signal processing that promises enhanced security. This blog, crafted by Vaishnavi S. Gate from Sardar Patel Institute of Technology, Mumbai, explores her MATLAB-based Audio Password Verification System. This innovative project authenticates users by comparing spoken passwords via correlation analysis, leveraging digital signal processing (DSP) principles to filter noise and evaluate similarity, offering a glimpse into the future of authentication technology. Project Overview The core problem: Authenticate users by measuring similarity between a stored audio password and a test sample. The algorithm involves recording clean audio, adding noise for realism (though not directly in the final code), filtering with a FIR low-pass filter, and computing metrics lik...
