PIs Apu Kapadia and David Crandall at IU, and Denise Anthony at Dartmouth College, have received a $1.2M collaborative NSF award (IU Share: $800K) to study privacy in the context of wearable cameras over the next four years. The ubiquity of cameras, both traditional and wearable, will soon create a new era of visual sensing applications, raising significant implications for individuals and society, both beneficial and hazardous. This research couples a sociological understanding of privacy with an investigation of technical mechanisms to address these needs. Issues such as context (e.g., capturing images for public use may be okay at a public event, but not in the home) and content (are individuals recognizable?) will be explored both on technical and sociological fronts: What can we determine about images, what does this mean in terms of privacy risk, and how can systems protect against risk to privacy?
