What Happens When an Acquaintance Buys Your Data: A New Privacy Harm in the Age of Data Brokers

Abstract

Data brokers have begun to sell consumer information to individual buyers looking to track the activities of romantic interests, professional contacts, and other people of interest. The types of data available for consumer purchase seem likely to expand over the next few years. This trend invites the emergence of a new type of privacy harm, "relational control "-the influence that a person can exert on another in their social or professional networks using covertly acquired private information.
