Canon Files For DSLR Iris Registration Patent

An anonymous reader writes "Canon has filed for a patent for using iris watermarking (as in the iris of your eye) to take photographer's copyright protection to the next level. You set up the camera to capture an image of your eye through the viewfinder. Once captured, this biological reference is embedded as metadata into every photo you take. Canon claims this will help with copyright infringement of photos online."

Nothing to do with copyright

Canon has filed for a patent for using iris watermarking (as in the iris of your eye) to take photographer's copyright protection to the next level.

No, putting your photos on a CD or DVD and then following these instructions takes it to the next level. It helps that a)you have the RAW files and nobody else does and b)most cameras encode their serial number into the EXIF data (or similar for a RAW image), and if you have proof of ownership of said camera...

I didn't see anything in the patent summary provided by the linked site that related to ease of copyright enforcement. Just:

Alternatively, by embedding personal data which is biological information in the image of a subject as an electronic watermark, falsification can be prevented more robustly.

Wow, you don't say. We can do that now- it's called Digimarc. They'll even crawl the web for you and look for images with your Digimarc watermark. Too bad it costs about a zillion dollars- their pricing model means that only a small number of pros use it (and you pay for both per-image watermarking, AND the services like web crawling.) This technology is sufficiently expensive and limited in scope to mean that it will never make it into anything except the 1D series cameras- it probably wouldn't even make it into the _0D series.

I really don't see an application for this technology, except for *maybe* press agencies, where they want to (more) easily track who took what photo. This is a fairly painless way of doing so; you no longer need to track who has what camera (Canon and Nikon provide loaners for repairs and loaners for special events, which means that no, it's not 1 person, 1 camera. Pro's also often shoot with more than one body.)

Though really, they could do the same thing with a microSD slot (where shooting preferences could be stored, too) for a lot cheaper. The only thing this gets them is more "proof", maybe- if they can somehow provide tamper-proof metadata (supposedly, the "data verification kit" from Canon provides verifiable images, but I've never seen even the most basic description of how it works.)

Or worse. Your camera gets stolen and is used to photograph illegal activities. The images are then posted on the net with your watermark on them. Cops arrive at your door and your life is history.

Yeah, but as soon as the patent describes the technique publicly, it would be possible to extract the metadata block from someone else's photos, use the same technique with that data, and extort money from someone, e.g. "Don't want these photos of kiddie porn signed with your iris? Put ten million dollars in non-consecutive unmarked bills in a brown paper bag under the mailbox at 5th and Rochester."

Am I missing something?

Don't look into viewfinder with remaining eyeball

[billstewart]

I'd much rather set the metadata to some passphrase of mine which I can choose for the occasion than be stuck with at most two sets of metadata for all my pictures. Or if I really wanted a biometric, a voiceprint would be more useful (because I could say something like "Washington DC, Nov 5, 2008" or whatever useful tagging I want.) Or even a thumbprint would be better than my eyeprint.

And then there's that James Bond movie scene ....

Glad this is not in place yet.

So your photographer gets laser surgery and due to the differences in the outer part of the eye the signature is different and now they don't match their old photos? Yes, LASIK (for example) doesn't affect normal iris scans because those use IR to scan the iris itself. But this apparently takes a picture of the eye. And yes a picture can be affected by eye surgery.
