Unfortunately, the milliseconds-long auctions that determine which ads you see also expose your personal information to thousands of companies a day. Under the proposed settlement, Google must create a new privacy setting (the “RTB Control”) that allows people to limit the data shared about them in RTB auctions. If the proposed settlement is approved, Google will have to inform all users about the new RTB Control via email. If the settlement is approved, regulators and lawmakers should push Google to enable RTB Control by default. Strong privacy legislation can make privacy the default, not something that individuals must fight for through hidden settings or additional privacy tools.
