Besides being an Android blogger a few of you may know that I specialize in Network Security. It warms my heart to see security related apps being made for Android devices. A great developer form the XDA has come up with an app that encrypts text messages and sends them as an audio file.

The app is called Stegdroid and it’s currently in its alpha testing stage. Scan the QR Code below to join in on the testing and more information directly from the horse’s mouth follows the jump.

Hi guys/gals

I’m working on this app for my final year dissertation. It performs Echo Steganography on wave files. My app uses this to encode short text messages in an audio file, then share it. I’ve just got the Steg side of things working, so I wanted to get some early feedback on whether it works for other people (and if it’s awfully slow – it uses a lot of Fourier Transforms etc…).

This is very early days, so the app isn’t anything like ready for primetime yet, but the basics are in place. I’d really appreciate it if you could download it and:

* Have a go at embedding some text in a recording and seeing if it correctly extracts it again.
* Run the tests available in the menu
* Email me one of your recordings (tfmw2 [at] cam [dot] ac [dot] uk) to see if I can extract the data on my phone.

Updates

* Supports encryption with a shared key
* Transcodes audio files to ogg format for sharing

Any problems let me know (expecting quite a few at this stage!)
