Anti-Spoofing Voice Commands: A Generic Wireless Assisted Design

on YouTube ↗06m

" summary

Prototype system builds three WISE versions using RFID, Wi‑Fi, and inaudible acoustic sensing and adds one‑time random noise to shelter transceivers. RFID uses noise‑like CW to hide EPC, Wi‑Fi rotates constellation per packet and skips preamble, acoustic uses OFDM with similar scrambling. A neural net fuses audio plus sensing to verify liveness and identity. Tested in six real environments with 12 users, verification stays >90% and dual‑channel replay is rejected >99%.
