Tracking Suspicious mail and pictures

Now that the UK is monitoring lots of email and telephone/cellular traffic,
there are some interesting solutions the intelligence community has problems with it:
It is called Steganography!

There are also programs like
1)Encrypt Text in Picture :
(Encrypt text in to a processed picture.
Encrypt Text in Picture - can hide the text into a picture. Support jpg, jpeg and bmp image files. You can send a common picture to anyone with the special classified message.)

and
the FREE
2)Hide In Picture (HIP) is a steganography program. It is a program that allows you to "hide" any kind of file inside standard bitmap pictures. The pictures look like normal images, so people will not suspect they contain hidden data.
You can use a password to hide your files, and only those who know the password use are able to retrieve them - without it, people cannot even be sure there is something hidden in the image.


I don't think that they have a backdoor key to decrypt this, and first they have to know that 'something' is in the picture,
you think they gonna check all the pics on the net?

Second, you can use a Military Standard Encryption program to encrypt a protected doc file that on its part is encrypted in an encrypted zip file that is encrypted in a rar-file
If you can unprotect this 4 times encrypted file in an encrypted picture,
you are good!

So is this interesting or not?

Interesting? Ok, yes. But after reading this I will be certain never to accept any pictures from you on line......

PS: I suspect if you can post this, then the "gov't" alreadys knows it.

Although not actually steganogrpahy, check out Dataglyphs. It is a way to encode digital data within the half-tone used for printing images.
