MIRAGE: Full-Body Bystander Privacy for Smart Glasses with Consent-Based Restoration
MIRAGE masks full-body biometrics on smart glasses and restores footage only with consent.
MIRAGE is a three-tier privacy system for smart glasses that conceals full-body biometric cues, including gait, posture, and silhouette, while allowing synthetic body replacement and encrypted consent-based restoration. It was implemented on a Raspberry Pi 5, companion phones, and a cloud generative backend. Visible-body detection reaches 0.948 average precision and 0.976 average recall. Bounding-box masking reduces silhouette re-identification to 10.86% Rank-1 versus an 11.12% chance level, and adaptive gait identification falls from 90.25% to 26.20% Rank-1.
