- post to random newsgroups, use textual mimic functions, send
decryption keys after the stegoed data has been distributed to
disguise data until it is too late to affect distribution
- become a spammer, or employ some spammers. Spammers use the hit and
run approach with disposable accounts; with sufficient availability
of accounts, and the economic incentive they seem to flourish in
spite of intense displeasure of recipients.
- video signals: live porn shows, one on one "chat live to our model,
she will do anything you ask, blah, blah" -- high volume, easy
target for stego, plausible reasons for anonymity
- subliminal channels in the TCP/IP and IPSEC protocols. Someone
posted a reference for an implementation of some subliminal channels
in the linux TCP/IP stack.
- VR gaming, VR chat rooms with audio, video; this could be a higher
bandwidth version of IRC.
- Subliminal channels in computer generated random numbers for
multi-player internet based games. (Death match doom with
subliminal channels, or with audio, video, etc)
Not a very super-highway like subliminal network possibly... mostly
the internet is not up to real time VR, video chat, etc. for the
majority of users at present. Many of the better applications for
subliminal channels are currently impractical.
When people can buy a T1 to their house for £2,000/yr instead of
£20,000, we will stand a better chance.
