It could be anything really but the signature can be deconstructed into a binary representation. This is kind of neat in that it can survive a crop or certain encodings if the message is more important than the image. However, it's the other way around for my use case. Sounds abstract but I'm looking for ways to ghost-sign original images. >>4153
Hmm, this actually worked! Really simple use of common utilities and provides a nice container for anything. Thank you this is pretty useful for hiding easter eggs (or an encrypted mess for that matter). Opens up possibilities with other image formats that rely on different compression algorithms.>>4160
I've seen a similar program but I end up with noticeable artifacts all over the image. Last one I tried (can't recall the name) even had some kind of verification to prevent forgery but degraded the image to the point where it was unusable. However, it was pretty good at hiding the payload in innocuous image formats intended for the web.
Thanks for the suggestions my dear Lainons!
