I'm sorry for dismissing this so quickly. Let's go ahead and try this. I
think it would be interesting. I am really to busy to do this, but I'll do
my best to find some time.
I would like you to give me a series of pictures specifically as a test. I
do not want to try to detect possible pictures from a third party source
that may or may not have messages. I want you to be able to tell me
definitively which ones have messages and which ones don't.
You can grab a set of pictures from anywhere or use your own if you are a
photographer. Put steganographic messages is some of them. Send them to me
as e-mail attachments (they don't have to go to the whole list). I will try
to analyze them and tell you which ones have messages and which ones don't.
I'll also try to give a percentage rating of how sure I think I am. I'll
post my guesses to the list, and you can tell me how many I got right and
how many I got wrong.
This actually sounds like fun, and I was really annoyed that my immediate
response was that I was too busy to do this. I get so tired of being to
busy. I need to make time for fun stuff like this.
