CLEAR: Online Speech Content Leakage Estimation through Cross-ASR Disagreement
Bhawana Chhaglani, Tanvi Kandepuneni, Jeremy Gummeson +1
Signal-level speech privacy mechanisms suppress linguistic content while preserving acoustic information needed by downstream sensing applications. However, their privacy settings…
ErgoAssist: Cognition-Aware Posture Feedback in Wearable Ergonomic Systems
Sarmistha Sarna Gomasta, Bhawana Chhaglani, VP Nguyen +1
Prolonged digital device use has made poor posture and musculoskeletal discomfort pervasive among knowl- edge workers. Existing ergonomic wearables rely solely on posture threshold…
NeuroPriv: Adversarial Representation Learning for Privacy in Wearable EEG Systems
Sarmistha Sarna Gomasta, Bhawana Chhaglani, Prashant Shenoy
Wearable EEG systems may expose sensitive information beyond their intended health function, creating substantial risks to neuroprivacy. In this work, we show that commonly used EE…
