Invited to present StegDroid at SBSeg 2011

I have been invited to present StegDroid at the WTICG – SBSeg 2011 workshop, which will take place in Brasília, Brazil.

[translation] The Brazilian Symposium on Information Security and Computer Systems (SBSeg) is a scientific event promoted annually by the Brazilian Computer Society (SBC). It represents the main forum in the country for the presentation of research and relevant activities related to information security and systems. The 11th symposium will be held between 06 and 11 November 2011 in Brasilia, DF, and is organised by the group of Network Engineering and the Department of Computer Science, both from the University of Brasilia.


The accepted version of the paper is available online at the SBSEG site.

StegDroid reaches the blogosphere!

StegDroid’s been covered on Mobility Digest, and Crypto Pig! Already over 200 users, which for an alpha build of a dissertation project isn’t bad!

Update (2/2/11) Now featured on the home page of xda-developers too!

Update (8/2/11) StegDroid has reached France, and more blogs!


This is a first release of my Dissertation project Android app: StegDroid. It uses Echo Steganography to hide small amounts of data (A text-message’s worth) inside an audio message recorded from the microphone in your phone in a basically un-perceptible way. The data can be encrypted with a password. This is very early days, and there’s a lot of work to be done, but if you’re interested please have a go. QR code after the break.

Update – Now on the Android Market
