Is steganography like cryptography?
It’s a close cousin. Some steganography algoritihms hide information so it can’t be found. Others hide it with a key. If you don’t know the secret phrase or password, you can’t get the information out. Q: Why is the book called Disappearing Cryptography ? A: When the first edition was published, the word “steganography” was pretty uncommon. So we coined the title “Disappearing Cryptography.” It was meant to be both flashy and make a point. A few cryptographers don’t think that steganography can be secure. They don’t understand how that the categories blend together. Some stegonography algorithms are relatively insecure, but others are just as secure as basic cryptography and the output is in camoflage.
