Lensless Gaze Is Not Private by Default: Auditing Identity Leakage Across Disclosure Surfaces
The research audited identity leakage in simulated lensless gaze sensing pipelines to show that visual unintelligibility does not guarantee privacy. By testing multiple disclosure points—from raw data to compressed outputs—the study found that subject-correlated information remains highly recoverable, shifting security focus from optical encryption to auditing data handling stages.
