Vision for Privacy: Privacy-Aware Visual Sensing

The millions of smartphones that people use every day are sophisticated computational and sensory devices. A variety of powerful and potentially transformative applications could be created by aggregating together data from the cameras and sensors on these phones in order to observe the world at a massive scale and in real time. Emerging technologies such as augmented reality glasses (e.g., Google Glass), lifelogging cameras (e.g., Google ClipsNarrative Clip, and Autographer), and head-mounted cameras (e.g., Snapchat Spectacles) are also expected to make cameras and such applications ubiquitous. However, such ‘visual social sensing’ would raise major privacy concerns because of the large amount of potentially private data that could be captured (see our exploration on ‘visual malware’ called PlaceRaider). Our research objective is to investigate how to use opportunistically-captured photos for innovative and potentially transformative applications, while providing guarantees on privacy to both people using wearable cameras and those in the vicinity of such cameras. We have also been exploring how wearable cameras can be used to enhance the privacy of people with visual impairments.
