I think that in such cases the rightful owner would point to the RAW photo on the blockchain and argue that his was published long before yours.

The remedy, in other words, remains legal. I see this as a tool for facilitating legal remedy. (Or have I missed your point completely?)

> his was published long before yours

That's not enough. What if someone publishes before the author. Say I buy something from other resource or even directly and publish it on the OP's.

I don't follow. Could you elaborate?

You know how you can download someone's video from YouTube, upload it somewhere else and make money off of it; what's stopping you from doing something similar with pictures here? Even better, with ether.camp you're an "author" since you published it first!

Next feature to add, or deriving business to create: add an indexer/comparison service that checks the JPEGs and to see how similar any two given pictures are, and if one derived copy sells anything, the creator of the original picture gets notified.

This could work from buyer/client side. If I want to buy image, I will check it with some service to be sure that I don't pay to pirate(newer&lightly changed image). But what If buyer doesn't use it?

I don't see the way how this could be implemented to blockchain. If every blockchain node downloaded and compared all images It would create massive bandwith and need for cpu/gpu power. Or am I missing something?

You are right, I don't see this going to the blockchain as well. But I am thinking of a service that runs outside of it, whose main purpose would be to provide (1) some legal support in case you want to file a copyright violation claim and (2) the basis for a reputation system.

Hi rglulis, yes thats a good potential feature for further down the road, we had ideas like that. To begin with we would be limiting such a service to the sellers within the content network itself, so the intensity of the checks are not that substantial. over time the extensiveness of this service would be expanded, first to not just check as sales get made, but to generally check on the content across the network, and eventually if viable to do web wide search as service to image owners (for fee of course). This would not be using blockchain (might be nice to use golem - eth supercomputer eventually though ;-) It would simply be a supporting service of the blockchain based photo sharing social network

Great feature, but I can't help thinking about the permissions you'd have to give for that

Yes, and that's an eternal problem inherent to the nature of digital goods.

Look at Steemit for examples of people making money from original content.
