ImageStamper: Prove your License

One of the problems with using images under a Creative Commons license is that, sometimes, those applying the license might change their mind and switch to another license. Though, in theory, that doesn’t affect those that used the work previously, it can be difficult to show which license the work was used under.

ImageStamper, however, feels it may have a solution for that problem, at least as it pertains to images. The idea behind the service is that, before you use a CC-licensed photo, you “stamp” it, creating a record of the date that it was found and the license that it was under at that time.

It seems to be a simple idea but the question is will it work and, if so, is it worthwhile? As usual, the answers are far from straightforward.

How it Works

To use ImageStamper, you first have to register for an account in the public beta. The process is very simple and only takes a few seconds.

Once in, you’re given two ways to “stamp” an image, the first involves pasting the URL of the page with the image (being careful to make sure that both the image and the license are on the page) and the second involves the use of a bookmarklet that you drag to your browser’s toolbar and click when on a relevant page.

From there, ImageStamp saves a copy of the image along with the license information and provides a permalink to access the image details (see example/original).

These permalinks are available to anyone, including those not logged into the site, so they can be presented as evidence in the event a dispute arises.

It is worth noting that the service will let you stamp “All Rights Reserved” images as well as CC ones, even though images without CC license probably should not be used.

All in all, the process is very simple and there isn’t that much to say about it. Currently, all accounts can stamp up to 1000 images, though more can be requested by sending an email to support.

Why Use It?

One of the largest fears many have had when it comes to the idea of using CC-licensed works has been that the licensor may, for whatever reason, change their mind about the license and back out. This could, theoretically, cause a conflict down the road when the licensor finds someone using their work and, thinking that they’ve changed the license, may not realize that the user obtained permission when the CC license was in effect. Some even think CC licenses could be used to trap unsuspecting users.

However, this fear seems to be largely unfounded. Though it could happen, most people don’t change their CC licenses (save, in many cases, to make them more permissive) and most who do recognize that those that used their work under the old conditions still have a right to do so. Most of the time, when one removes a CC license, they aren’t thinking so much of past works, but future ones.

Still, considering the potential risk, it is worth setting up a system to protect against this. Though there are countless ways to timestamp and affix a license to a work, most of them require the rightsholder to submit it. Non-repudation services (services that provide third-party verification of copyright ownership, date and time), such as Numly, Safe Creative, MyFreeCopyright, etc. protect the creator of the content and only Numly provides any means for the licensee to protect their interest.

The problem is that the vast majority of rightsholders upload their work with no sort of verification at all. ImageStamper hopes to fill in that hole and expand on the normal process by giving licensees a chance to use their own form of non-repudiation. It is a smart idea, if even the potential uses are even more limited than traditional non-repudiation services.

The question is whether anyone will use it and, if so, will it actually be able to fill its role.

Limitations

The biggest limitation is that, currently, ImageStamper only works with Flickr pages. Though there are plans to add new pages, including deviantArt, it isn’t possible to use this service with any page on any service. For example, if you find a CC-licensed image on a blog, you can’t stamp it.

Also, since the service focuses on images, you can’t use it to stamp text, video or audio. All in all, this means that only a small fraction of all CC-licensed work is available for stamping at this time. Though more will be available, it seems likely that, even at its best, only a small amount will be available for use.

The other problem is whether or not the service would be usable in a court of law. As with other non-repudiation services, if a dispute reached that point, the creator of the site would have to be deposed on how the site operates and whether the site would provide good evidence depends heavily on factors beyond the scope of this article including how it gathers the information, the security of the system, etc.

However, the main function, most likely, wouldn’t be to defend in a court case. As with other services, it is more a matter of winning in the court of public opinion, something it could help with most definitely.

Bottom Line

If you are using CC-licensed images from Flickr on a routine basis, it probably makes sense to consider adding this as a step in the process, especially if you are a corporate user or someone else that might make a good target for a lawsuit.

Though the odds of such a dispute are still very slim, it’s easy to see why many want to protect themselves against it and this service has the potential to add at least a thin layer of protection.

As with most solutions, it has a lot of room to grow and improve, but it is better than the current solution, which is none at all. Considering that it is free, at least for now,

In the end, how well the service does will likely depend more on the perceived need for it than the service itself. The question is whether there are enough people uneasy about using CC-licensed work to make it feasible and, if so, if they will be placated by what ImageStamper has to offer.

  • Hi Jonathan,
    I've started using Imagestamper and found it extremely useful. However, for the past couple of days, I've received an error message when I tried to add tags. The same thing happens if I don't add tags and simply press the image stamp button.

    I don't know if this is something you're aware of, or even if it is an issue (might just be me!).

    Hope to hear what's what.

    Cheers,
    Neil W
    PS: I'm using Firefox 3 on a Mac (OSX 10.5.6) in case that makes a difference.
  • Neil,

    Thanks for the input. Have you contacted the admins of the site about this? I really can't do much but forward this along to them.

    Sorry I can't be of more help.

  • Hi, I'm the developer of ImageStamper. Thanks for trying out the service and for an insightful article about it.

    Reading it made me realise that I ought to publish statistics on how often licenses change on Flickr; right now it is still relatively infrequent, but at the same time far more common than people seem to realise.

    Also, you may be aware that Getty Images have recently partnered with Flickr. They offer Flickr photographers the opportunity to submit photos into a Getty Pool, images in which will be considered for inclusion within Getty's commercial catalogue. However, Getty insist that CC-licensed images need to have their license reverted to All Rights Reserved. This creates a strong incentive for photographers to change existing licenses (more here: http://www.flickr.com/groups/gettyimagesonflick... )

    Please don't hesitate to contact me via support@imagestamper.com if you have any more questions. Thanks again!

  • First off, thank you for your comment and your compliments. I greatly appreciate it.

    If you have statistics on this, I would love to see them. I've never had this happen in my personal experience and do not know anyone directly who has it happen, at least not to the point they were threatened with any kind of action, so some hard numbers would be greatly appealing.

    I had read about the partnership with Getty, it had been a long time in the making and it seems that it just now finally reached some level of completion. I didn't realize though that it required users switch their license back to ARR. That is interesting and a bit worrisome. However, I don't think A) A large % of Flickr users will take Getty up and B) That many of the CC crowd will want to anyway.

    Still, something to follow with great interest. Thank you for the heads up on all of this.

    As it happens, I know that a commercial food blog based in the US was subject to just such a licence-jacking. The royalty demanded was low, and paid for that reason, but if this became more common, it would cut into budgets.
  • That is interesting, can you have this person get in touch with me or email me their contact info so I can talk to them about it for a future article? This is something that interests me greatly. I'd also like to talk with the CC organization about this.
