Marketing Ethics: Metadata
Everyone generates metadata when using technologies such as computers and mobile devices to
search, post, tweet, play, text, and talk. What many people don’t realize, however, is that this
treasure trove of date, time, and location information can be used to identify them without their
knowledge. For example, in analyzing more than a million anonymous credit card transactions,
researchers at the Massachusetts Institute of Technology were able to link 90 percent of the
transactions to specific users with just four additional bits of metadata, such as user locations
based on apps such as Foursquare, the timing of an activity such as a tweet on Twitter, or playing
a mobile game. Since there are more mobile devices than there are people in the United States,

up all sorts of metadata that will let them tie a majority of purchase transactions to specific
individuals.
