A puzzle that requires finding hidden data in various media forms, such as text or images.
Steganography is the art of concealing data within another message.
The concealed message can be plainly visible, or it may require advanced cryptographic techniques and data manipulation.
For example, a message could be hidden in the alpha transparency bits of an image, such that it doesn't make any difference to the naked eye.
