Our mobile phone is today our most precious and condential partof us. In many cases we do not only share phone number with it, butalso our most private information. This information is to some extensionnaively shared and gathered without our knowledge. As the number ofadvanced and sophisticated services increase the more sensitive informa-tion we seem to throw at them. To prevent privacy intrusions Googles'soperation system Android uses something called permissions. Permis-sions are a decision to allow an Android application access to a resourceon a specic device. Once a permission is granted there is no possibil-ity for a user to verify that the application does not take advantage ofthe given trust. With granted permissions applications can collect a vastamount of information without any connection to the service it provides.To highlight this problem we present the KAUDroid platform, a two part,Android application surveillance system. KAUDroid consists of an An-droid application that collect permission usage on phones and a centralserver responsible for data storage. Information is presented to the publicthrough a web user interface using graphs to visualize data in a under-standable manner. With this tool we hope to raise the general awareness ofhow third-party applications tend to abuse their trust and to help peoplerecapture their unconsciously lost privacy.
