Methods to Hide/Encrypt Data

What are the alternatives to Hide/Encrypt Data on disk. Like:

  1. Encrypt using normal encryption alogrighm.
  2. Remove first 16 (or so) bytes from file and store it somewhere else. This will propably make it unreadable.
  3. Shuffle bytes of file with tracking.

etc. What are other alternatives?

I need to encrypt data in 3 to 4 ways/level so that, recovery tools cannot recover it.

Note: All methods should be able to get back the original data.

"Steghide is a steganography program that is able to hide data in various kinds of image- and audio-files. The color- respectivly sample-frequencies are not changed thus making the embedding resistant against first-order statistical tests. "

  • The most secure system any one person can imagine is likely not secure.

It is very simple to encrypt using existing tools such as Truecrypt, PGP etc., such that a forensic tool will not retrieve the datunless they have your passphrase. This is standard. What do you need to do that requires more?

If, however, you are storing something very sensitive, there is no way to prevent against the Rubber Hose attack, so perhaps multiple layers of encryption could provide you with a level of deniability. There used to be a tool called, I think, RubberHose which encrypted volumes in such a way it was impossible to prove whether there was any further level of encryption used.

Just use some kind of standard encryption algorithm. These are tried and tested - anything you try to do yourself is open to you leaving some kind of security hole.
