Nearly 250 million video surveillance cameras have been installed throughout the world, and chances are you ve been seen by several of them today.
Recognition algorithms have become far more accurate, the devices we carry can process huge amounts of data, and there s massive databases of faces now available on social media that are tied to our real names.
This leads to a situation that conjures up our worst fears with surveillance.
That s no small adjustment.
That involves dealing with the thorny legal and ethical issues of notice-and-consent, data ownership, and our relationship to the devices around us.
We could choose to expand the classes of protected uses — such as we do in the U.S. with health data — or follow the European model of creating more expansive laws around personally identifiable information in general.
