Welcome All

As a start, this blog is mainly for investigating techniques where two parties can communicate over elementary communication channels without anyone noticing.

A basic example: cheating in a test. How to do it without the proctor noticing? Of course, personally, I do not like that (being the 'proctor' in many cases :) ). But, this can have quite a high research value.

Many techniques exist with complicated schemes, and high throughput. However, we are here concerned with the simplest of forms; two people waving at each other, opening your web browser or not, is your cell phone working or in flight mode, ...

So, if you are not familiar with what is going on in the hard-core research community regarding these techniques, don't panic, you are still welcomed, and you can still heavily contribute (or not, who will know :) )
