Hiding messages as noise in bitmaps
Encrypted texts have one disadvantage: Everybody can see at once, that they are encrypted.
But would you expect important data in a low-quality scanned holiday foto?
...Best off you are there, where no one is looking for you.
So take any picture, add some colourful noise using a noise-filter and
put your password etc. into this bitmap - hidden as more noise.
(And then excuse my bad English ;)

This Delphi project can
- encrypt data in form of noise in a bitmap
- extract data hidden in a bitmap
- protect the pixel-keys with passwords
