{{Event
|Short Title=Federal Agencies Use a Large Database with Location Information
|Location=United States
|Date=early 2020
|Taxonomy=Aggregation, Surveillance, Secondary Use
|Personal Information=Location, Contact, Computer Device
|Threat Actors=US government, Apps collecting location data
|Affected Individuals=Smartphone owners in the United States
|Summary=In early 2020 the US government was found to have bought access to a commercial database of location information from millions of cellphones in America.
|Description= At the beginning of 2020 Trump administration appeared to be using a commercial database that maps location data of millions of people. 

Several privacy violations can be identified here. 

The database is an example of [[Aggregation]]. It is reported to be potentially the largest location database in history. It includes location information of 12 million people as they moved through several major cities in the US, including Washington, New York, San Francisco, and Los Angeles. 

Smartphone tracking is an example of [[Surveillance]]. This data allows the government (or anyone else who has access to the database) to map movements of phone owners. 

The location data in the database is drawn from smartphone apps including those for games, weather, e-commerce, for which the user has granted permission to log the phone’s location. Sharing the location data with the US government, who are using it for immigration and border enforcement, can be interpreted as [[Secondary Use]].
