Personal Data Sharing by Mobile Apps
"Who Knows What About Me? A Survey of Behind the Scenes Personal Data Sharing to Third Parties by Mobile Apps," by Jinyan Zang, Krysta Dummit, James Graves, Paul Lisker, and Latanya Sweeney.
We tested 110 popular, free Android and iOS apps to look for apps that shared personal, behavioral, and location data with third parties.
73% of Android apps shared personal information such as email address with third parties, and 47% of iOS apps shared geo-coordinates and other location data with third parties.
93% of Android apps tested connected to a mysterious domain, safemovedm.com, likely due to a background process of the Android phone.
We show that a significant proportion of apps share data from user inputs such as personal information or search terms with third parties without Android or iOS requiring a notification to the user.
