Respectful Cameras :

A new type of video surveillance protects the privacy of individuals.

A camera developed by computer scientists at the University of California, Berkeley, would obscure, with an oval, the faces of people who appear on surveillance videos. These so-called respectful cameras, which are still in the research phase, could be used for day-to-day surveillance applications and would allow for the privacy oval to be removed from a given set of footage in the event of an investigation.

"Cameras are here to stay, and there's no avoiding it," says UC Berkeley computer scientist Ken Goldberg. "Let's figure out new technology to make them less invasive." According to a 2006 report prepared by the New York Civil Liberties Union, the number of publicly and privately owned video cameras in Lower Manhattan increased by a factor of five between 1998 and 2005, and several thousand cameras are in place in Greenwich Village and Soho alone. The United Kingdom, however, holds the record for video surveillance. In a report filed on Tuesday, the information commissioner there estimates that there are four million video-surveillance cameras in the United Kingdom--that's one for every 14 people. Goldberg thinks of the respectful cameras as a compromise between advocates for privacy and those concerned about security.
