Metadata: The Eyes Have It?

Confused? Intrigued? We're both. And we wonder if this is for real.

We recently came across a blog claiming that Canon has filed for a patent to "take photographer's copyright protection to the next level," according to PhotographyBay.com. The method? Iris watermarking — that is, the iris found in your eyeball.

The idea is that a photographer can register "biological metadata" contained in an image of his or her own iris, then use it to protect the copyright of photographic images. According to the report, the proposed invention "makes it possible to protect the copyright of photographic images by reliably acquiring biological information of a photographer for the purpose of personal authentication."
