Technology that determines an individual’s identity or location has been the subject of significant media attention in the first half of 2018: Amazon made news with the sale of its facial recognition technology to law enforcement, the U.S. Supreme Court ruled that the government generally must obtain a warrant to access certain types of geolocation information, California arrested the Golden State Killer using the DNA information of a relative, and Facebook came under fire for the way in which Cambridge Analytica accessed the data of tens of millions of users. Garnering less attention, but of no less importance, are the legislative efforts underway in the federal government and in many states to regulate these emerging technologies and limit the ways in which this information can be collected.
