•These papers are excellent introductions to Steganography and a few of them get a little more technical than this presentation and are highly recommended if you are interested in further exploring technology.
•The noted RFC’s are a bland read but you all already know them by heart anyway, right?  Take a look through these and other network protocol RFC’s and you’ll be amazed at the abundance of unused and reserved space in the protocol headers as well as header fields that are used for singular purposes and may be able to be used or modified without impact to their function.
