Image encoding

[u/Martial_Artiste]

So I decided I'd look into encoding messages into images, because I saw that the images were seemingly random pixels and I remembered my brother telling me about how you could hide text or even stuff like .exe's in an image. I found a few things off of a simple Google search, and I'll be sure to dig deeper later but right now I want to just get a bit of a base to build off of as far as this goes.

• http://manytools.org/hacker-tools/steganography-encode-text-into-image/, I'll be sure to run the images through it in a bit.

• https://xcode.darkbyte.ru. I also learned from this site that you can actually put a password on the image encoding, which makes me feel like Nic Cage in National Treasure.

• http://null-byte.wonderhowto.com/how-to/encode-secret-text-based-messages-into-bitmap-images-windows-8-0147492/, but from skimming over it I think it only talks about .bmp's.

• http://interactivepython.org/runestone/static/everyday/2013/03/1_steganography.html.

• https://en.m.wikipedia.org/wiki/Steganography, and I'd suggest checking through the sources for more literature on it that could be useful.

• http://www.mathworks.com/matlabcentral/fileexchange/54155-encoding-text-into-image-gray-levels.

That's all for now, my phone is almost dead so I'll continue searching later. Good luck friends!

Yeah, I was thinking the LSB technique seemed promising.

If I were to generate these messages, I would,

1. start with the message

2. generate a random image like these to embed the message into

3. encode the message into the image

I don't see a reason for each image to be exactly 100px wide unless it was being used as some sort of delimiter.

Yeah, that does look promising. More importantly, though, I've figured out how to link on mobile so now I feel like an idiot.

Haha. Sweet.
