Randomized trial demonstrates reduced identity inference in Wi-Fi beamforming, suggesting a viable defense mechanism.

The aim is to develop a defense mechanism against gait-based identity inference using Wi-Fi beamforming feedback.
Simulation-based approach with N=20 and SNR=15 dB.
Implemented WalkAnon to perturb Givens rotation angles in beamforming frames.
Evaluated the effectiveness against a nearest-centroid attacker on circular-variance features.
Achieved ~2% mean throughput loss and p95 at ~6%, compared to ~20% for uniform noise.
WalkAnon maintains high output quality in standard-compliant beamforming vector.
Generalizes effectively to Wi-Fi 7 with configuration for up to 16 streams.
