Fun with steganography. · 4:01am Feb 22nd, 2016
So, you might have seen this image on the internet:
Well, what you don't know about that exact image, the one I linked to, is that it has been modified using a steganographic algorithm. For those of you who don't know, steganography is, according to google:
the practice of concealing messages or information within other nonsecret text or data.
And I acquired a piece of software that can encode and decode text into an image. So, the image above now contains the first chapter of Lupine Tree. Fitting, no?
The image won't appear for me! God damn you mobile! God damn you! Also that sounds fucking amazing, I'm so putting an assload of swears in a project with that.
3769550 It's not you, it's imgur. You can't link images from there here on FiMfiction anymore. I forget specifically why.
That said, the image is broken in the blog post.
Harvey Kinkle and Danger Dolan? Are you mad?
3769555 Oh yeah, they said something about it disobeying their terms of use. Something about not using it to host images on other sites, although it's been a bit of a inconvenience they handled it like rational adults, which is a lot more than other companies do. So they have my vote of approval for that.

Image should be fixed now.
Woah. I. love. it.
3769579 That is fucking badass! And I really want climb onto that thing's neck and yell "And you thought treeants were bad!"
3769593 Forget treeants. Treewolves are much worse. Or better. The vote's still out on that.

3769626 treeants are giant human like being made from, well, trees. They're sentient, moving trees. But yeah treewolf is still better.
3769579 also I just encoded a comment on a story, for shits and giggles!
That looks amazing
Wow. Very fitting!
I suddenly have the urge to try and decode every image on the internet in search of... stuff. It feels like going to the beach with a metal detector. Probably not going to find anything, but the idea that you might....

Actually finding if an image has something else encoded in it is difficult enough, but there are several different methods (of which I used the most basic), and that's all assuming that you A) know the method to retrieve the data, and B) can decrypt it if it has been further encrypted.
I will tell you this, however: stock images that you have to pay for often, if not always, have a steganographically hidden "watermark" that allows the owners of the image to find it if it's been shared online. Movie footage, especially unpublished footage, sometimes has things hidden in it; for instance, when distributing an unreleased movie clip, the sender will encode the recipient's name in it, and each recipient gets their own name encoded. That way, if a clip is leaked, you just have to decode it to know exactly who to blame.
Awesome picture, and a genius idea

They said there'd be treants

3769740 That's really cool. I think they might do that with the scripts for movies as well.
I remember a while ago the FBI apparently found terrorist info hidden in this fashion in some porn on a flash drive.
Have you tried to fit all the chapters you've published so far into the picture? Will it degrade the picture visibly?

The picture is too small, and my program crashes if I resize it too much larger. No, it has no visible effect (at least, not to the naked eye).
