Reply to comment by volci in A group of researchers has achieved a breakthrough in secure communications by developing an algorithm that conceals sensitive information so effectively that it is impossible to detect that anything has been hidden by thebelsnickle1991

Is stenography used for security? No. It is used for plausible deniability. For security there is encryption. You understand the difference do you not? When you need both you use both of course.

Maybe it shouldn't be ...but it is

Steganography is confused for security.

Steganography can help security but it is not security. It increases the work needed for discovery and only that.

Analogous to the difference between cover and concealment: "Cover is protection from the fire of hostile weapons. Concealment is protection from observation."

Steganography is like "concealment" but not like "cover". To have "cover" you need encryption. You can have one or the other or both.

Steganography is a form of security

To that you reply

Obscurity can help security but it is not security is it? You know better than that to believe that so why do you reply to me with ‘Wikipedia disagrees with you’?

Here is what the wikipedia link you shared says:

>> Whereas cryptography is the practice of protecting the contents of a message alone, steganography is concerned with concealing the fact that a secret message is being sent and its contents.

Concealment can help you avoid detection but concealment does not offer protection does it? If someone has a gun a pile of leaves may conceal you but will it protect you? What do you suppose happens to those who confuse concealment for cover (which does offer protection)?

Do you genuinely not understand the difference between stenography vs cryptography and the different purposes (as Wikipedia explains) they have? Are you being disagreable on purpose to act like a troll? Why then are you being disagreable? What is your purpose?
