Just wanted to share an idea after hearing your talk at FOSDEM.
Web servers like nginx, lighttpd, apache, could use a blockhash module that would calculate (before serving an image) or fetch the blockhashes from an existing database and then keep the hashes in a cache.
As images are served to web clients, the blockhash metadata could be part of the HTTP headers served along the image, then web browsers/web clients could use the blockhash information for automatic attribution purposes.
