Background / Scenario
The advantage of steganography over cryptography is that the secret message does not attract any special attention. No one would ever know that a picture contained a secret message by viewing the file either electronically or in hardcopy. In this lab, you will use Steghide, an open-source steganography program, to hide a data file within an image file.
Objectives
Use steganography to hide a document within a JPEG file.
