IP over Voice-over-IP for unobservable censorship circumvention

There is a different approach to evade censorship. FreeWave transforms Internet traffic into acoustic signals which are then carried over Voice-over-IP providers.

The design is agnostic about the Voice-over-IP provider that might be used.

You can read the paper here:
http://www.cs.utexas.edu/~amir/papers/FreeWave.pdf

The paper refers to a prototype implementation so their is no deployed systems right now. The system aims for unobservable censorship circumvention in the first place. It can be combined with something else to achieve anonymity.

I’m a little concerned about the data rates that can be transfered. However censored users should be happy to get information. The paper suggest to use video signals to achieve higher data rates. I really like the idea in general.
