Privid: A Privacy-Preserving Surveillance Video Analytics System
Mar 29, 2022
A group of academics has designed a new system known as " Privid " that enables video analytics in a privacy-preserving manner to combat concerns with invasive tracking. "We're at a stage right now where cameras are practically ubiquitous. If there's a camera on every street corner, every place you go, and if someone could actually process all of those videos in aggregate, you can imagine that entity building a very precise timeline of when and where a person has gone," Frank Cangialosi, the lead author of the study and a researcher at the MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL), said in a statement. "People are already worried about location privacy with GPS — video data in aggregate could capture not only your location history, but also moods, behaviors, and more at each location," Cangialosi added. Privid is built on the foundation of differential privacy , a statistical technique that makes it possibl...
