In secrecy, the “apps” forward private data to a third party. Computer scientists from Saarbrücken have developed a new approach to prevent this data abuse. They can put a stop to the data theft through the app “SRT AppGuard”.
The producers of anti-virus software have been making vivid predictions of such scenarios for some time now; in the meantime, scientific studies also prove the threat. A study from the University of California in Santa Barbara (US) concluded that among 825 examined apps for the iPhone and its operating system iOS, 21 percent forward the ID number, four percent the current position, and 0.5 percent even copy the address book.
Michael Backes and his team of researchers now bring this abuse to an end. Their approach focuses on Android. It is the most common operating system for smartphones and tablet computers. Developed by the Google software group, this freely available operating system is used by several mobile phone manufacturers, and since November 2011 is activated daily on more than 700,000 devices.
However, Android is known for its rigorous policy on assignment of privileges. If a user wants to install a downloaded app, he learns via a list which access rights to data (location, contacts, photos) and functions (Internet, locating) will be claimed by that app. Now he has two options: Either he accepts all conditions, or the app will not be installed. After the installation, the privileges cannot be revoked. “Moreover, many developers generally claim all rights for their app because the concept of privileges of Android is misleading, but they want to ensure the smooth functioning of their app nevertheless,” explains Philipp von Styp-Rekowsky, PhD student at the chair in IT security and cryptography.
This “sink-or-swim” strategy is put to rest by the researcher from Saarbrücken. The app “SRT AppGuard” based on their approach determines, for every application installed on a smartphone, what it accesses, and shows this information to the user. Privileges can now be revoked or granted to the respective app at any time. The researchers have already published the app on the platform “Google Play”. It can be downloaded there for free. It runs problem-free on Android 3.x.x and higher. The development of the app has been taken on by the enterprise Backes SRT, which was founded by Backes in 2010. It is also located on the campus in Saarbrücken.
But the Saarbrücken app can do even more than just providing alerts. It is also able to block suspicious requests or change them so they cannot do any harm. “Thus, we can also prevent the use of known security vulnerabilities of the respective apps or Android operating system,” adds Professor Michael Backes. This possibility is very important if the manufacturer cannot provide security fixes in time,” says the professor.See also:

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
