..If the government were to demand pictures of citizens in a variety of poses, against different backdrops, indoors and outdoors, how many Americans would readily comply? But we are already building databases of ourselves, one selfie at a time. Online images of us, our children, and our friends, often helpfully labelled with first names, which we’ve posted to photo-sharing sites like Flickr, have ended up in data sets used to train face-recognition systems. In at least two cases, face-recognition companies have strong connections to photo-management apps. EverRoll, a photo-management app, became Ever AI (now Paravision), and Orbeus, a face-recognition company that was acquired by Amazon, once offered a consumer photo app. And even when our images are supposedly protected on social-media sites like Facebook, Instagram, and YouTube, how secure are they?
