Image copyright protection method of blockchain

Short answer question

Please briefly describe the basic steps of the proposed image privacy protection method.

What parameters can users set when uploading images? What impact do these settings have on image transactions?

How to use hash algorithms to ensure the copyright of images?

What role does the smart contract play in? How does it ensure the credibility of transactions?

How to use asymmetric encryption technology to protect the content of traded images?

Why is it said that it can effectively protect the rights and privacy of image owners?

What is the difference between the "right to use the image" and "full copyright of the image" mentioned?

If other users want to view the private part of the image, what operations do they need to do?

How to prevent other users from illegally obtaining image resources through screenshot software?

How to use the traceability of blockchain to record the use of images?

Short answer question answer

Users upload images and set parameters; the server preprocesses the image and generates a smart contract; the server initiates a transaction to the blockchain network to record the copyright; other users pay to trigger the smart contract to complete the transaction.

Users can set whether to allow copyright transfer, usage rights trading, and paid viewing of private content, and set the corresponding price. These settings determine the transaction method and price of the image.

The unique hash value of the image is calculated using a hash algorithm as an identifier and recorded on the blockchain to ensure that the copyright ownership cannot be tampered with.

Smart contracts automatically execute image transactions, including copyright transfer, usage rights transactions, and private content viewing, ensuring that transactions are credible, traceable, and irreversible without a third party.

When the image is delivered, it is encrypted using the recipient's public key, and only users holding the corresponding private key can decrypt and view it, ensuring the security of the image content.

Blockchain technology is used to confirm rights and transactions, and private content is protected to ensure that the image owner has full control over his or her work and can benefit from it.

Image usage rights allow users to use images but cannot be transferred, while full copyright allows users to own, use, and transfer all rights to the image.

Other users need to pay the corresponding fee to the image author to obtain the permission to view the private part of the image, and this permission is not transferable.

The server generates derivative images of different resolutions, and only low-resolution images are displayed in the user's personal space to prevent users from obtaining high-definition original images through screenshots.

The blockchain records all transaction information, including image usage records, and users can query the copyright ownership, usage history, and original author information of the image.
