Twitter Pictures as a Steganographic Channel
AbstractSteganography means hiding a hidden payload within an apparently-innocent cover, usually an item of digital media. Most pure research focuses on bitmap or JPEG images, or simple video codes. In practice, there are often further constraints: the carrier might recompress or damage the object. This project is primiarly programming. First we must characterize the properties of image transmission through Twitter, and then provide an implementation of image steganography through it. This might be a complete piece of software with a nice interface, if the channel is straightforward, or a proof-of-concept if the channel causes difficult noise (in which case we will need suitable error-correcting codes.)
Prerequisites: Linear algebra. You will need a Twitter account and to learn the Twitter API without help from me. It would be useful to know a little about the JPEG image format before starting the project.
