summary

System authenticates users by measuring speaking-induced body sound in the ear canal and exploiting left/right asymmetry, claiming passphrase-independence and spoof resistance. It maps air-to-in-ear signals with cycleGAN, estimates ear transfer functions for asymmetry, and classifies with a GMM-UBM i-vector pipeline plus an ensemble tree fused by soft voting. Prototype evaluation on 23 people achieves 3.64% EER after 75 seconds enrollment, shows robustness to noise, motion, and replay attacks.
