Steganography


Recommended Posts

"Detect" ? The effect system in Paint.NET is not designed to be useful for image analysis...

But it's not difficult to do. Assuming you have a place to output text, all you need to do is get the last bit of each byte of a pixel's color, (eg, yellow (ffff00) would yield 110 from 11111111 11111111 00000000 and place it into a string of bits and then convert that to text and output it.

If I knew how CodeLab deals with color values/debug text I'd write it myself.

Well, if it's not difficult to do, then go ahead ;)

What you describe is simply one stenographic algorithm. I'm sure BoltBait or one of the other CodeLab gurus would be able to quickly implement this.

OK, I'm on it!

I played around with CodeLab today and came up with a decent algorithm. I'll publish something in the next day or so... Hang tight. 8)

...could it be a subject for your "How to Write an Effect Plugin (Part 3 of 3 - Advanced)"?

I'm not on it because:

1. I don't know (yet) how to read/write files. I think we need it here!

2. If you create such plugin you will have to decide several rules (how many bits to encode a letter? Casse sensitive Y/N? A=001 or A=ascii code? etc...) So you could code/decode picture only with this plugin and can't decode 'external' pictures IMO.

3. bits handling?! I need to improve myself on this stuff!

Yeah,I also put the finishing touches on the UI.i think the UI is very good.You can try it. :lol:

I don't understand what you mean...

 

The Doctor: There was a goblin, or a trickster, or a warrior... A nameless, terrible thing, soaked in the blood of a billion galaxies. The most feared being in all the cosmos. And nothing could stop it, or hold it, or reason with it. One day it would just drop out of the sky and tear down your world.
Amy: But how did it end up in there?
The Doctor: You know fairy tales. A good wizard tricked it.
River Song: I hate good wizards in fairy tales; they always turn out to be him.

Ah, should've guessed. None of its posts really made sense...
