Stego

Steganography or stego is a way of hiding information inside a picture, text, or audio file.
In the example below I’ve hidden a technical drawing inside the picture of a Ferrari.
To anyone it looks like the picture of a car, but hidden in the redundant bits of info is the other picture.
This can be used to pass information to other people without anyone’s knowledge.The person receiving
the message only needs a password to decrypt the file.
It is said that Al Qaeda is communicating with it’s people by hiding plans in porn pictures or Ebay sales.
I used Hide in Picture to do it! Download the software and see for yourself….
