yes, I understand. But even if technically possible, it won't really solve our problem. It might solve hotlinking, but not copy&pasting our images / cropping them and uploading them elsewhere, which happens probably just as frequently if not more frequently than just using our own CDN link. Furthermore, there's a small hidden benefit of people who do hotlink to our CDN - it makes it potentially easier to trace. Copy&pasters would require a more sophisticated search which is either labour intensive to do manually for us, or costs money to do via API. My main concern is not about technical aspects, but rather legal, ethical and practical. Primarily, how to deal with sites that rely on user-generated (or user-stolen) content where offenders might keep on doing this...
