What kind of deniability are you looking for?
There are perfect forward secrecy/security for communication protocols (OTR
for chat, ECDHE key exchange for SSL), and for file storage there is
Truecrypt hidden volumes. These can all to some degree protect against an
attacker figuring out what the data is (by different means).
