Canon's eye-based biometric photo watermarking system hits the Patent Office

Nilay Patel

Image attribution is big business on this tangled web of ours, but embedding digital watermarks into images is a costly and time-consuming procedure for most photographers -- which is why this Canon patent application is so intriguing. The filing describes a "Registration" mode for digital cameras that embeds biometric data captured from your iris in the image automatically as a watermark -- you simply set yourself as one of up to five users, look into the viewfinder for a moment so the camera can scan your eye, and start taking photos. The system embeds the metadata in batches to avoid slowing the camera down while you're out in the field, and it sounds like the system can be modified to simply generate a verification code instead of a true watermark, preserving image quality. Of course, this is just a patent application, so there's no word on when or where we might see this tech pop up, but you know photographers will be all over this when it finally hits.
