I made something cool, and I just wanted to share it.<p>There was an article submitted here last month, about forensic analysis of a recent Victoria's Secret photo (Discussion here: http://news.ycombinator.com/item?id=1017726)<p>It raised my interest, and I thought it was a great article. HN User slig made a quite comment about how some parts of it would be pretty easy to implement as a 'web app'. Turns out he was right. I read up on the theory in the linked research paper, and here is the result of a few days work:<p>http://www.errorlevelanalysis.com<p>Any thoughts or suggestions, I'd love to hear them.
I like it, but would like to see something more general.<p>Copy-move detection would be neat: <a href="http://www.lemonodor.com/archives/2008/02/protecting_journalistic_integrity_algorithmically.html" rel="nofollow">http://www.lemonodor.com/archives/2008/02/protecting_journal...</a>

If the theory is correct, on a cursory glance I'm not convinced, then could you not do a quick analysis to give a numeric likelihood of the image having been tampered with?
