Only 3 weeks after the release of SoniControl app on the Play Store, we already got downloads from all over the world ! Thank you all for your interest !
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 this 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 – Source Code. The code is released under GNU license. Everyone is welcome to contribute to our project. Get in contact with us!
The project SoniControl will be presented at the “Tag der offenen Tür” of the Federal Ministry of Science, Research, and Economy on the Austrian National Holiday (26.10.2017). The project will be shown from 10am to 4pm! We hope to see you there to show you a demo 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!
We have recently finished our real-time ultrasonic signal detector. The detector is able to detect different types of transmission technologies and is robust to various types of noise sources (e.g. broadband noise), music and speech artifacts. Now we will port it to native code and integrate it into our Android App!
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 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.
We have published our SoniControl Wiki which contrains a comprehensive collection of links, literature and background information about ultrasonic communication technology. You find the Wiki under “Resources”!
P3TV has compiled a TV report about the SoniControl project. The report can be found here!
Novel technologies like Google Nearby and Silverpush build upon ultrasonic sounds to exchange information. More and more of our devices communicate via this inaudible communication channel. Ultrasonic communication enables to pair devices, exchange information but also to track users and their behavior across several devices similar to cookies in the web. Every device with a microphone and a speaker is able to send and receive ultrasonic information. The user is usually not aware of this inaudible and hidden data transfer. To overcome this gap, within the project SoniControl we research the current capabilities of ultrasonic communication and raise awareness for this unknown communication channel. To date there is no technology available that detects ultrasonic communication and that enables the user to protect his or her privacy. We develop a mobile application that detects ultrasonic activity, notifies the user and blocks the information on demand. Thereby, we want to raise the awareness for this novel technology and help users to protect their privacy.
