Recently I participated in a CTF game which held a number of steganography challenges. This got me really interested in steganography.
From what I understand steganography is most commonly used with images, data hidden in images. this is because images hold so many bytes adding hidden data is easy as it does not distort the disguise enough to be noticed by a human and if the image is fresh and has no other original it cannot be compared to the source image to spot that there is potentially hidden data.
So now on to the main part of the question:
What other digital applications are practical in communicating secret messages using steganography?
If you were constantly sending large pictures of cats to a receiver it might be fairly obvious you are up to something. is there anyway to hide data within web traffic or text messages which does not reduce the integrity of the steganography?
what other crafty ways are there to use steganography? could I encrypted a random normal string and hide an encrypted string within the bytes of another encrypted string, making the first string un decrypt-able but obscuring the secret point?
I am curious in the subject and its other more crafty application.
to narrow it down into one question!:
Are there forms of steganography which don't use media files such as images, sound files or video clips? but follow similarly used methods. e.g. Pictures keep their true meaning but have bytes hidden amongst their own original bytes
