Actually I have a book on Cryptology that serves my needs for now. I was looking over some math notes from a textbook I have and a section in Linear Algebra briefs over some applied Cryptology in mathematics. I'll check the book you recommended.

It is usually based on slightly changing RBG values.
Now try looking for changed values in the Stego 1 image.

1) Define RBG values please, never heard of the term before
2) How do RBG values change, how can I determine a change, & what can I do with such change?

GTADarkDude, thanks for the article. No offense to bluesun but I thought the article was poorly written and mediocre at best. I could write an analysis of why I thought the article was poorly written but that isn't the point of this thread. I still need help solving stego1, and learning the basics.

I usually spend majority of my time helping users with their questions or maintaining the IRC server with fellow opers. I'm fairly erudite in various topics but this is something I am a true neophyte in [steganography/cryptography]. I am naturally talented in mathematics, I am willing to learn the a...
