Encryption is different and it's not usually compressed.

Encryption is a form of reencoding of the signal using a method that is kept
at least partially confidential.

And addition is a form of manipulating numbers using a method
that is kept at least partially confidential. (they don't
say which numbers they add in the algorithm, and not what
comes out).

Hey, algorithms and variables must be a new idea to you.

The same is true for compression, except that
it is not kept confidential.

It's kept as confidential as good encryption.

Data is normally compressed before encryption,
using a cryptographically-safe algorithm.

Name a "cryptographically-unsafe algorithm".

Ciphertext is incompressible, if it
comes out of a good algorithm.

That has nothing to do with compression before encryption.

Are you now saying that an encrypted signal is the same as noise

It should look just like random noise, if it is well encrypted. There will be
no discernable pattern or redundancy in the signal.

So it's the same or not?

You can paint an orange green and someone might think it's an Apple
but it isn't.

Yes, that's the idea (for encryption).

idea for encrpytion is patented.

And you are wrong, encryption is not steganography.
