Facial-recognition technology will make life a perpetual police lineup for all

Police body cameras are widely seen as a way to improve law enforcement's transparency with the public. But when mixed with police use of facial-recognition tools, the prospect of continual surveillance comes with big risks to privacy. Facial-recognition technology combined with policy body cameras could "redefine the nature of public spaces," Alvaro Bedoya, executive director of the Georgetown Law Center on Privacy & Technology, told the US House Oversight Committee at a hearing on March 22. It's not a distant reality and it threatens civil liberties, he warned. Technologists already have tools, and are developing more, that allow police to recognize people in real time. Of 38 manufacturers who make 66 different products, at least nine already have facial recognition technology capabilities or have made accommodations to build it in, according to a 2016 Johns Hopkins University report, created for the US Department of Justice, on the body-worn camera market.
