No Chance for Data Leeches

KIT Researchers Have Developed an App to Protect Mobile Data without Limiting the Usability of Popular Apps

Messenger, games, fitness trainers: Internet giants offer millions of apps for download in their stores. Many of them are supposedly cost-free. However, users are data sources that can be used to make much money by many app and advertising network operators. Researchers of Karlsruhe Institute of Technology (KIT) and the FZI Research Center for Information Technology, an innovation partner of KIT, have now developed an app to better protect own data.

 

Your location, communication, purchases, preferred films and music, everything is recorded by app providers. Whoever attaches importance to data economy had to evade digitization to the largest possible extent in the past. Many persons considered this no viable option. On behalf of the Baden-Württemberg Foundation, KIT researchers have now found a remedy and have developed a data protection app that allows unrestricted use of popular, but information-hungry applications.

 

So far, it has been necessary to manually change authorizations of each individual app on the smartphone to prevent undesired data drain. In many cases, this was impossible, because the app simply stopped working. Now, a few clicks are sufficient. The AVARE program can be installed on Android devices like an app and creates a closed domain into which the other apps can be packed. This domain then controls communication between these apps and the operation system. “We have looked for a solution to use all apps without any restrictions, but to transmit own data in a controlled way only,” says Dr. Gunther Schiefer, Head of the Mobile Business Group of KIT’s Institute of Applied Informatics and Formal Description Methods (AIFB). If an app packed into AVARE tries to access contacts in your address book, AVARE enables the user to share individual contacts only and to restrict the data released to the mobile phone number, first name and last name, for instance. “The address or a date of birth are not required for a chat,” Schiefer says.

 

In addition, AVARE can reduce the accuracy of location data and extend them to a radius of several kilometers, such that a weather app, for instance, continues to supply reliable prognoses without recording the building-exact  location of the user. When using apps that do not work without general access rights, AVARE will go even further in future: “Then, we will play in wrong data that can be recognized to be wrong. The microphone interface is transmitted a noise, the camera interface a black area or cloud image. And the interface of the address book shows the emergency phone numbers of the fire department or breakdown service.”

 

The AVARE code is available as an open-source software at: www.avare.app. Researchers hope that their program will be used by other developers who will help extend the current beta version in order to obtain a version 1.0.

 

The AVARE project was funded by the Baden-Württemberg Foundation (www.bwstiftung.de) under the research program “IKT-Sicherheit” (ICT security).
