Face-blurring Technology To Protect Your Cctv Privacy

摘要

Should we modify our conception of privacy thanks to the seemingly unstoppable spread of CCTV surveillance networks? Jack Brassil thinks so. He's a computer scientist at Hewlett-Packard's laboratory in Princeton, New Jersey, who is testing a technology called Cloak that aims to limit the extent of privacy invasions. "Rather than prohibit surveillance, our system seeks to discourage surveillers distributing video without the authorisation of the surveilled," he says.rnCloak has two key requirements. First, CCTV users, such as municipalrncouncils and businesses, would have to sign up to a system that electronically obscures the faces of people who do not want their pictures to be published in video footage that is passed to others. The list of such people would be akin to the national "do-not-dial" lists designed to prevent cold-calling, Brassil says.
