Wow! Excellent replies.
So why doesn't somebody in California get in touch with Audible Magic and find out about licensing options. If they are a normal business, I am sure they would be interested in licensing their technology to another single business who could be 'the' copyright enforcer for the porn industry. Money is always important to any business, and everybody knows that the porn industry means money.
as for developing your own software for this and worry about patents. all you need to do first, is pay a patent office to do a worldwide search on patents related to this. if patents exist only in the US, then I believe you can patent in the EU or somewhere else without problems.
Expensive? It probably is. But all it takes, is a single company to start investing in this, then offering their services to the webmasters. That company could make a nice profit if they do things right. In the article mentioned by Varzi, it states that 13 companies are developing such applications, so there could be cheaper solutions already available.
I might be wrong, but after reading more on this on the net, I think that eventually such video analyzing services will be made available to the public. Most likely not now, but 1-2 years from now. Right now the big guys are gonna start using it (Myspace, Youtube, movie studios), but eventually there will be companies popping up, offering services that will enable you to upload your video and get it's 'video dna' file created for a fee.
So let's say this service becomes available tomorrow. That's nice.
But what about a company, dedicated to the videos on porn tube sites?
You see, it's one thing that Youtube is gonna use this technology, since they got the videos they need to analyze. But you can only analyze something, that you have something to compare to. So it's one thing YOU uploading a snippet from a tv show to Youtube, but Youtube has to have that 'video dna' file for that TV show in order identify it as a copyrighted material.
So it's a matter of either Google going out and analyzing ALL video content in the world (or the tv stations at least ), or it's done proactively by the tv stations themselves. they submit their videos to google for analyzing and 'video dna' file creation, because they want to protect their content.
Now, do you think that Google in this case would allow porn videos to be submitted like this? I am not sure.
Do you think that porn tube sites will invest in licensing this technology to protect themselves? I don't think so?
So it is upto a third party company, to generate these 'video dna' files for adult contents, AND to search the porn tube sites, analyze their videos and find copyrighted material. This is the service that will have to be created for the porn industry then.
Money. Not sure how much licensing technology would be, but if it's something realistic, then it should be nothing more, than a software that you pay royalties after each file analyzed. You can easily push this cost onto the webmaster submitting their original contents. It will boil down to cost vs. loss due to tube sites for a single video, for the webmaster. If it's worth like 10-20 bucks (no idea, just throwing out numbers) for a webmaster to not a video of theirs on tube sites, then they will do it and this service/company will work.
In my mind, the above scenario is almost inevitable, just a matter of time.... and who will take initiative.
