Best way is to make an MD5 hash of your images, then download the web and compare... ;)

Good suggestion... a good way to catch the really dumb theives.. but I'd like to find something a little more robust... md5's will fail if the image has been altered in any way.

I've been working on and off on something like this, so far it can recognise images that have been modified slightly (eg resizing, resaving, minor changes in colour and saturation) but it cannot handle crops.

What is really needed is detailed image analysis to create several keys, with each describing small parts of the image, eg a 3 pixel triangle, or two blobs that are X distance apart. Keys from the copyrighted image are compared with keys in the database, and the best matches throw a result.

This is not simple by any means, and it will also detect images that are very similar (for example two cropped images of the same model with a similar facial expression in each)

Been using Digimarc for many, many years, though they used to have another service where you'd pay a yearly fee and they'd scan the 'Net for your images.

The cropping is a problem if someone is eliminating your watermark.

This is the feature I would really be interested in.

That went out the door when Penthouse sued her for the Busty Babes CD series. You cant just scan Penthouse magazines and resell them for content.
