Hi, this is Lee's partner in Sniffy....
What sniffy could do is detect if your images were used on another website and report that website to you. If a site resized the image, then that would make it difficult to detect since sniffy works by calculating a unique (hash) value for each image it finds. So if your pic is 1024x768 and someone resized it to 800x600, sniffy would consider it to be a different picture and wouldn't know how to relate the two together.
Most likely images will stay the same size (since most content providers produce web-friendly sizes) so detection of an image is very possible.
If the image were a sponsor banner, then sniffy could find the occcurences of that banner on websites since webmasters wouldn't change the size of the banner.
Think of sniffy as like a bloodhound. You have to give him the scent of what he is supposed to find. If you give sniffy the image to find, he can then search out and find it.
There are companies like Cyveillance who focus on protecting copyright/branding for a company.
Sniffy works similarly, but different, in that sniffy is geared towards validating sponsor's affiliate websites to ensure that the affiliates are not supporting CP related activity.
