How to implement a data hiding method in a binary image?

I have the following article:

http://pdf.aminer.org/000/322/254/digital_watermarking_using_shuffling.pdf

I do not have much experience in image processing and I have to write some code to implement the method for data hiding in a binary image that is described in the article above. My problem is that, beeing unexperienced, I have difficulties in understanding what the program is supposed to do.

What do you think? Do you have any links for an article or some similar code for data hiding in a binary image?

I need some help! Thank you!

See my attached demo, for what it's worth. No, it doesn't do the paper you mentioned but you might find it somewhat interesting. And here's the FAQ: http://matlab.wikia.com/wiki/FAQ#Can_you_program_up_the_algorithm_in_this_article_for_me_and_explain_it_to_me.3F

And could you help me achieving the result in that paper? Do you think that it is hard to do what the paper talks about?

Or is your code somehow adaptable to what I need? Even if the result will not do exactly what the paper says, I need the result to at least be close to what it is talked about in the paper... Thanks for your help!

I didn't even look at the paper. I don't even have time to look at papers that I'm interested in, much less what others are interested in. You're a smart engineer and I'm sure you can do it without me.
