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) and lifelogging cameras (e.g., Narrative Clip and Autographer) 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 work 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 the smartphones and the people who are near the phones.
