Facebook AI Research says it's created a machine learning system for de-identification of individuals in video. Startups like D-ID and a number of previous works have made de-identification technology for still images, but this is the first one that works on video. In initial tests, the method was able to thwart state-of-the-art facial recognition systems. The AI for automatic video modification doesn't need to be retrained to be applied to each video. It maps a slightly distorted version on a person's face in order to make it difficult for facial recognition technology to identify a person.

The FBI quietly developed a facial recognition network that allows law enforcement to identify people in the United States without their knowledge. Now lawmakers want to know why the agency didn't tell people about it. "Why did the FBI not fulfill the requirement of the law?" asked House Oversight Committee chairman Jason Chaffetz at a hearing on Wednesday. The FBI didn't let citizens know the agency was collecting photos from motor vehicle departments, according to a report from the Government Accountability Office. And a lot of people can be found on law enforcement facial recognition networks -- around half of American adults, according to a study from Georgetown University's Center on Privacy and Technology.

Police departments across the country may know what you look like, even if you don't know how they got your photo. About half of American adults are already in a "law enforcement face recognition network," according to a new study published Tuesday by researchers at Georgetown University's Center on Privacy and Technology.

A Denver Police Department officer uses a camera to shoot video of bystanders. To many, perhaps the most surprising thing about the report is that it found "face recognition is neither new nor rare."
