Let's say you are an artist and want to sell a limited edition run of electronic prints. You would issue colored coins that are partially embedded into the print itself. You would be able to authenticate your ownership by signing your colored coin that is verified to be the print number that is owned by you. If you sell the digital print, you will also have to transfer the colored coin. If you sell the digital form, the image would need to be re-hashed and a new colored token would be created that would be traceable to the previous token. If multiple tokens are hashed, they would be seen in the blockchain. It behooves the owner to never expose the original to the internet. You would need an offline or sandboxed device to render the image for display purposes.

So, u r talking about replacing third party authentication of digital signature through a decentralized public ledger ? 2 questions...

1. What would be the miner's benefit to maintain the blockchain ?

2. Is not ethereum already working on it ...a distributed database ?

What I understand about your concept is an image will open only with private key. But image is about showing others, unless it is a secret doc. Does it find any purpose in the normal concept of image sharing ?

No. Any digital image can be copied, but images encrypted that can only be displayed with special software will help protect your purchase from being copied if you don't want it to be. It's only to prove authenticity, not copy protection.

While folks are working on creating asset tokens for Bitcoin 2.0, I would ask for development of an image format akin to DRM that first checks the blockchain for the outputs before accessing the image data. Then anything done with the image like printing, displaying, or selling would require a transaction (with a fee) and would remove the color from the token.

Important documents would be authenticated by the author as a notarization. This wouldn't deter copyright infringement, but would be useful for authenticating original artwork. Rights for displaying lower resolution images in the case of artwork could be granted with different color (and cheaper) tokens.

This would mostly be useful when it is important to authenticate the originality of the document or artwork. For instance, applications could be developed that prove that "selfie" images were taken by the camera installed on the device. Games like "Magic: The Gathering" could sell virtual cards displayable once on a device. And of course, contractual tools could be developed.
