      I'm guessing they'll use some kind of watermarking. But, do you really want every photo you take to be unambiguously traced back to you? On one hand, photos you take can be traced back to you. On the other hand, the watermarking or metadata could probably be removed by a third party. It seems lose-lose for the camera owner.

            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."

              Now that I think about it, that's a good point. There are ways to hide watermarks, and make them difficult to find/remove, but they tend to degrade signal/noise ratios (not good for a camera, at least of professional quality. Most pocket cameras I know have plenty of noise to hide the watermark in), and it'd be a fairly CPU intensive process inserting it. So, you have a point there.

      Or don't buy the camera?

      This is something Canon would tout as a feature of their camera, for which artists would pay a premium, so that they could more easily prove that a particular photo belongs to them.

      Keep in mind these are people who (1) earn their daily bread by taking amazing photos, and (2) often have to endure years and years of dry spells before one particular photo hits the big time and generates widespread interest. They have a very strong interest in controlling the reproduction and use of their photos, so they can get paid for their years of effort. A feature like this, sort of an automatic unfakeable "signature" embedded in each frame, would make it much easier for them to prove that a given photo is their property.

      You might not like that of course, but that just means you're not a photographer. Presumably when it comes to whatever you do creatively, that takes years of discipline and effort to do, and which puts the food on your table, is not something you'd like people to just be able to duplicate and distribute randomly and broadly without even asking you first.

      Think of it as the equivalent of your engraving your SSN on your very expensive tools, so that if they're ripped off you can prove they're yours.
      • And if your tools are ripped off, you can also add the frisson of identity theft worry to the nuisance and cost of replacing expensive tools.

        What percentage of the professional photographers' work is work-for-hire? Does the watermarking survive the printing process? Will the watermarking survive the web-sizing?

        However, as noted above, I would be concerned about freedom of the speech and the press if the photos could be traced back to the photographer.

      • Or don't buy the camera?

        Or don't have a choice? This sort of technology could be easily abused and inserted covertly into most, if not all, cameras at the bequest of governmental intelligence agencies. This has already happened with ink jet printers which secretly print a serial number, traceable back to the purchaser, on every document printed. Abuse of this kind of technology is a threat to already threaten free speech.
      • Speaking as a photographer who has had his work used in print and on-line, (including photos of Mexico used in brochures put out by the Mexico department of Tourism), I can say that *NOBODY* deserves to get paid for mediocre work, and if you're going through a 'dry spell', then you're doing mediocre work.

        Pro photographer here:

        It's not that hard to prove ownership of photos (for purposes of copyright assertions). I've gone head-to-head with people a couple times to prove that I created (and therefore was the owner of) the work in question. Nobody's ever argued that, really.

        The problem with copyright is more on the law side than the proving ownership side. Copyright attorneys are wildly expensive, and cases are usually long and drawn-out. Plus, just holding the copyright only entitles the owner to sue for actual damages. Only when the work is registered Federally within 90 days of publication (first use) can the owner sue for anything more than actual cost (IE, damages). Hopefully damages are enough to cover not only the bills, but the work missed while in court.

        I would much rather see a less tiered system where any use outside of fair use (and I have a broad view of fair use) is open to suit for cost as well as damages. I don't mind seeing one of my photos on a MySpace page or copied to someone's blog (especially if I'm actually given credit), or even if someone goes to my site, grabs a bunch of photos and makes a screensaver FOR THEMSELVES, but I can't stand it when my photos are appropriated into ads, tourist sites, news sites I didn't contract with, etc.

        It is much easier (and cheaper) to spell out user licenses and sue for breach-of-contract than it is to get anyone on copyright infringement and actually have it be worth your time to pursue.

        In my estimation, the ONLY good thing to come from the DMCA is the ability to serve voluntary and involuntary infringers with takedown notices relatively easily and cheaply.

    That sounds pretty easy to strip out after the fact. Or, for that matter, to add in. What makes this any better than adding your name or email address to the metadata, as most cameras allow you to do now?

    Proving an image is yours generally isn't even a problem. Online images are lower resolution versions of the originals, only the photographer will be able to produce an image with many times the quality of the online version. The problem is a) finding out that your images are being used without your permission, and b) getting it to stop. Both of these are made much more difficult by the global nature of the Internet, and neither of them are made any easier by this iris watermarking, as far as I can tell.
    • If it's not defeated, watermarking does make it easier to find copies of your images. You only have to process each image on the web once to find your watermark. Without watermarking, you'd have to do a pairwise comparison between every image on the web and every image of your own.

    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.)

However, it must be quite redundant, cover the entire image, and not affect the output, through all kinds of filters that post processing entails. This is a difficult problem, IMO.

      I have seen some photographers not even bother to go after the unauthorized or unlicensed use of their images... that is until they are published someplace with deep pockets who is likely to quickly $ettle well when sued.

      Another issue is the fact that the camera is NOT taking an image of the photographer's iris *every time* the button is pressed and then real-time embedding it into the RAW CCD dump before compression, post in-camera processing, etc..
      This may as well be something that is done from the PC/Mac Editing workstation using special watermarking software when memory cards are dumped if it is not to be in-camera and real-time every-time.

      I remember being on "assignment" and shooting "humorous" pictures that were not necessarily related to my paid task, which later were widely circulated in company-wide email (say, like when I caught a police officer in his patrol car SLEEPING... I silently placed dozen krispy-kremes onto his hood just in front of his open window (as I maniacally laughed inside my head while rubbing hands together)... Boy, and I am sure glad that that officer could not 'prove' who shot the images. Heard that the police chief got a copy too.. LOL Parking ticket payback.

      Pro gear or not, any "big glass" shooters will have that crap switched off in a heartbeat if the embedding technology affects/delays shooting performance in ANY way. I know many pros who only shoot in "manual" modes because the internal computers on modern digital cameras inpart too much delay (ANY is too much for a Pro). Typically the only auto feature used are AP (Aperture Priority) with Ultrasonic/Hypersonic (Canon/Nikon) autofocus lenses... the rest are more/less for noobs and wedding photographers.

      It also has been my experience that effective watermarking would require some form of "crippling" in Photoshop (and any other pro editing software apps used in the biz). Thjis is just another in the long line or DRM. If you can detect it, there too is a way to remove it. (If anyone would like an example, take some high-rez RAW images of US paper currency (20's and higher I believe) and then attempt to edit those files at high res in Photoshop (el al) and then print them on a high end color printer. The software and the printers are deliberately modified to not allow the operations (by design) because they "recognize" the US currency and prevent the operation. I believe color copiers also have this "feature". []
      I see this technology as also requiring a level of watermark removal prevention built into the software. Nothing like everyone's secret-sauce editing followed by flattening and a batch-resize with unsharp-mask followed up with everyone's favorite RGB->CMYK conversion (and color loss) to have fun with watermarks. Many imagers I know, wipe their metadata to help mask technical details of how the shot was made (or in my case I'd put made-up BS data in there, f32, ISO6400, 1200mm, etc..)... there are many copycats out there in the competitive world of photography. Something like this reads to me to be a possible new file format. That alone would kill industry-wide adoption (unless it is FREE and far superior compared to JPG, TIF, and RAW "lossless" CCD dump formats.)
      I'd like to see how Canon implements it and how useful it actually *is*.

    Using a biometric identifier for watermarking is pointless and only broadcasts your biometric id across the world. Biometric ids are there for proving that you are you, not that something belongs to you.

    If you have a good watermarking scheme, embed a string like "This image is Copyright 2008 by ..." into the images. If, for some reason, you want to sign your images digitally, sign them digitally.

      As said above: Turn it off, or don't buy that camera. I'm not particularly sold on it myself, so I won't buy it (that and I shoot Nikon, and I've already invested in lenses).
    • Perhaps someone should modify the camera to sign each key with your PGP private key stored on microSD. A little more fool-proof.

    just put your signature on a piece of paper, scan it with a flatbed scanner and save as a couple of the popular file formats used for computer graphics (jpg, png, gif) then resize them small enough to not be noticed and paste them on to your photos you want copyrighted/trademarked whatever, then nobody will know they are there unless they zoom in to 400% and look for the signature in a specified location, but since you keep all that your own little secret nobody knows they are there unless you need it to defend your self in the court of law...

    At best this will just encourage another RIAA-like lawsuit mill. Ultimately, I don't really see the benefit.

    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.
