Call me a cynic, but can't I change a pixel and use the photo w/o the copyright?

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.

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

But a pirate wouldn't need the original raw, just one that happens to produce the same jpeg.

The intent is to prove ownership, not to prevent piracy. You can't produce the 'owner' hash with your reconstructed RAW. I note they also only display low res until you buy a high quality version. That's what I do too. If someone wants to save/share my low res images its no problem. If they want something magazine or billboard res (ie commercial) they have to come to me.

If the pirate registers their own reconstructed RAW file, then there are two 'identical' pictures on the blockchain, and no way to tell which one is the real one. (It doesn't matter that the RAW files don't hash to the same value, because there's no authority who can tell you which version is the 'real' one).

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?

What's your "lets not turn this into decentralized eBay for child porn" story?

That is a very big problem!! but https://ipfs.pics/ to some solves this by using "Votes"

The trouble is, this assumes people will vote CP down.

I do not feel that confident in mass moral behaviour. Observe Reddit.

One problem would be people stealing others images for profit.

It is good to design systems with the assumption that most users will use them as intended. There will always be misuse, but that can be adressed later if the system is successful. Compare airbnb, uber, dropbox. They all have very bad use cases. The systems were designed for the vast majority of users being lawful and for the most part it works.

> It is good to design systems with the assumption that most users will use them as intended

This is terrible advice. But note that two of your examples have ratings systems as a first-line anti-abuse measure, and dropbox like all the other hosting services do notify-and-takedown for copyright infringement. They also disable dropbox sharing if it's too widely used.
