MIMOCrypt: Multi-User Privacy-Preserving Wi-Fi Sensing via MIMO Encryption. (arXiv:2309.00250v1 [cs.CR])

Wi-Fi signals may help realize low-cost and non-invasive human sensing, yet
it can also be exploited by eavesdroppers to capture private information. Very
few studies rise to handle this privacy concern so far; they either jam all
sensing attempts or rely on sophisticated technologies to support only a single
sensing user, rendering them impractical for multi-user scenarios. Moreover,
these proposals all fail to exploit Wi-Fi's multiple-in multiple-out (MIMO)
capability. To this end, we propose MIMOCrypt, a privacy-preserving Wi-Fi
sensing framework …
