excerpt: While it is important to examine the individual components of what is an increasingly pervasive and unregulated source of commercial surveillance in the “Big Data” era, such as in-store tracking of consumers, the Federal Trade Commission (FTC) must place this one use of mobile tracking in a larger context. Such tracking is but one part of a more elaborate and increasingly seamless “always-on” collection apparatus that operates across devices and user experiences. This surveillance is invisible to most consumers and connected to a range of other practices such as “hyper-local” targeting, multi-screen tracking, and data broker-driven offline and online “connected recognition” and data on-boarding services. Current self-regulatory approaches are ineffective and do a disservice to consumers by falsely claiming to provide privacy protection and user control. The FTC should issue a set of recommendations to govern cross-platform marketing that includes mobile devices. This is urgently required as intrusive geo-locational data-gathering practices, some of which raise concerns about the potential for new forms of “digital redlining” and other discriminatory practices, dramatically expand during the next few years. We believe it is especially important for the FTC to examine how geo-location tracking is being used to identify people by race, ethnicity, economic class, and by their age (such as young people and seniors). The FTC should also reiterate its call for Congress to enact meaningful omnibus privacy legislation.
