Thanks for your comment! > Sadly the "doesn't survive compression/re-encoding" problem is kind of a show-stopper Indeed, that’s true - fortunately there are already ways to at least limit the problem. There is some research under the umbrella of “robust JPEG steganography” which aims to persist the covert message among compression. But I don’t know how well this actually works. LSB steganography was just the most straight forward way for me to implement. Thanks for pointing out the security issue - I certainly wouldn’t have noticed it!
