Copyright protection method based on block chain and picture steganography

Abstract

The invention discloses a copyright protection method based on a block chain and picture steganography. A scheme of combining a block chain with picture steganography is utilized; confirmation disputes of the copyright of the picture work can be greatly reduced. A least significant bit of each pixel point component (rgba) of a picture is changed; wherein the picture effect cannot be identified bynaked eyes, so that extra information can be stored in the least significant bit of the pixel component, the information is hidden in the picture, the original effect of the picture is not changed, and once the decentralized distributed account book and the chained account book information of the blockchain technology are chained, the information cannot be tampered; based on an account system of an encryption algorithm, the security of private data can be effectively ensured; the programmed contract guarantees the automation and consistency of contract execution, reduces the cost of copyrightconfirmation, solves problems that a copyright owner cannot be found through authorization and authorization registration and charging are complex, reduces the cost of right protection, and reduces the number of processes.

Description

technical field [0001] The invention relates to the technical field of blockchain and image steganography, in particular to a copyright protection method based on blockchain and image steganography. Background technique [0002] In the Internet era, the storage and application of data is developing in a blowout manner. Data should generate value in the process of use and transmission, and the rich and colorful picture design consumes a lot of effort by photographers or picture editors; the theft of picture copyright, It has greatly harmed the interests of copyright owners. Therefore, the authorization technology for confirming the use of pictures has been paid more and more attention. This is an effective guarantee for maintaining copyright owners; [0003] Traditional pictures (including: computer pictures, scanned pictures after pen drawing, pictures taken by camera, pictures drawn by photoshop and stored on the computer, and rgb pictures made by other methods) have great ...

AI Technical Summary

Problems solved by technology

[0003] Traditional pictures (including: computer pictures, scanned pictures after pen drawing, pictures taken by camera, pictures drawn by photoshop and stored on the computer, and rgb pictures made by other methods) have great deficiencies in the copyright confirmation and authorization of works. The copyright registration period is long and the cost is high; and in the registered copyright system, the copyright certificate cannot confirm the unambiguous ownership of the copyright, it is only the registration authorization certificate under the registration protection system; and when the copyright is transferred or authorized to use, the licensor It is necessary to have a channel to carry out the authorization agreement with the authorized person, the communication cost is high, the efficiency is low, and the income is small; in terms of rights protection, the value of the picture is low, and the cost of rights protection is often greater than the value of the picture itself, which makes the copyright owner helpless to deal with the infringement incident
