The Federal Trade Commission (FTC) is the offical consumer watchdog in the USA. The FTC is particularly interested in dodgy marketing practices in the U.S. It is holding a workshop in Washington DC entitled Cross-Device Tracking. The workshop focuses on cross-device tracking, where what you do and how you do it is used to infer which devices probably have a common user. FTC: “Probabilistic” tracking is generally invisible to consumers and, unlike tracking through cookies, the consumer has no ability to control it. It raises a number of privacy concerns and questions.”]
