Adding Biological Copyright Metadata to a Photograph

Here’s an interesting development by Canon to try to help photographers protect and enforce the copyrights of their images.

Basically, Canon has filed for a patent on a system that examines the iris of the photographer looking into the viewfinder and embeds information about that photographer into each image that is captured.

I don’t quite understand fully how that helps, even after reading the full article available here, but it’s a story worth following.
