We are pleased to announce that SoniControl firewall app was released on the Google Play Store ! You can download it here: https://play.google.com/store/apps/details?id=at.ac.fhstp.sonicontrol The code can be seen and downloaded at this address: https://git.nwt.fhstp.ac.at/m.zeppelzauer/SoniControl And the documentation is on our website, under documentation. We are looking forward to your feedback !

The source code of the SoniControl Application has been released publicly as a GIT project. You can download it from our website: sonicontrol.fhstp.ac.at under Ressources – Code. The code is released under GNU license. Everyone is welcome to contribute to our project. Get in contact with us!

Exciting times in the SoniControl project: we are currently finalizing the last features of the SoniControl app. The alpha test will start soon! We will keep you updated.

The ultrasonic frequency band represents a novel and so far hardly used channel for the communication of different devices, such as mobile phones, computers, TVs, and personal assistants like Google Chromecast. Ultrasonic communication is a promising technology since it requires only a standard loudspeaker and a microphone (as built into our phones) for communication.

The project SoniControl will be presented at the “Tag der offenen Tür” of the Federal Ministry of Science, Research, and Economy on the National Holiday (26.10.2017). The project will be shown from 10am to 4pm! We hope to see you there to show you some demos of our prototype!

The SoniControl Project will be presented at this year’s ARS Electronica festival from September 7 – 10. See our live demo of how ultrasonic communication works and how we detect and mask it! You can find us in Postcity Linz, first floor, Room No. 11. We are looking forward to see you there!

The SoniControl prototype for the detection of secret ultrasonic communication is ready! In the last days we intensively worked on its finalization. The prototype runs in real-time and is able to detect different ultrasonic transmission protocols reliably. To test the detector, we encoded the text string “Netidee Rocks” by ultrasound and sent it through the Read more about Netidee goes Ultrasound![…]

We have compiled a set of ultrasonic audio recordings of different mobile apps including Google Nearby-based apps. Since ultrasonic sound is inaudible we have made the sounds visible (by computing spectrograms) and audible (by shifting their pitch to the audible range). The entire dataset can be downloaded under “Ressources” on the SoniControl webpage.

A recent study of TU Brunswick (Germany) reveals that many more Apps than expected use ultrasonic information exchange. More: here. The study can be found here. The SoniControl Project Team members currently work on real-time audio processing methods that enable a robust detection of ultrasonic information.

We have published our SoniControl Wiki which contains a comprehensive collection of links, literature and background information about ultrasonic communication technology. You find the Wiki under “Resources” on the SoniControl Website! Sharing is caring!
