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.

Download-and-Burn might just become the new mantra of the MPAA yet. Recently, the studios dropped their asinine controversial demands to retrofit set-top DVD players and DVD-ROM drives with expensive watermark detection technology. Instead, the demand is now limited to new devices with enhanced features such as the ability to burn downloaded movies or support managed copy; not to your run-of-the mill living room DVD player. Under the proposal, these so-called "enhanced devices" would also have to incorporate HDCP on all digital outputs as well as CGMS-A on analog outs in an effort to curb piracy. Something to keep in mind with your next TV purchase, eh? Sure, the watermark technology must still be chosen along with a new method for CSS authentication. But this clears the way for an overall download-and-burn agreement for standard-definition DVDs (not Blu-ray or HD DVD folks) which would allow the likes of Walmart, Target, and Best Buy to implement their download kiosks and enable the good peeps at Netflix to finally stream their flix into our homes for that sweet, sweet burn.
