Virtual ip protection method and system based on block chain against network generated pictures

Abstract

The present invention discloses a virtual IP protection method and system for pictures generated by a block chain-based confrontation network. The method includes: using pre-prepared training data to train a pre-built generation confrontation network model, wherein the generation confrontation network model Including a generator and a discriminator; converting the first user portrait into a first user feature vector through a preset method of extracting a user feature vector; obtaining a first random noise, and splicing the first user feature vector with the first random noise , to obtain the first image feature vector; input the first image feature vector into the trained GAN model to obtain the first user image image; calculate the first image feature vector and the hash of the first user image image Hash value, and write it into the blockchain as the hash value of the user's virtual IP. The invention can automatically generate images for user portraits, avoid related copyright issues, and prevent user virtual IPs from being infringed and tampered with.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method and system for protecting virtual IPs of pictures generated by an adversarial network based on block chains. Background technique [0002] In recent years, the research and application of blockchain technology has shown a rapid growth trend. Through decentralization, blockchain technology uses means such as data encryption, time stamps, distributed consensus and economic incentives to realize peer-to-peer transactions, coordination and collaboration based on decentralized credit in a distributed system where nodes do not need to trust each other, thereby It provides a solution to solve the common problems of high cost, low efficiency and insecure data storage in centralized institutions. Blockchain has the advantages of traceability, immutability, and anonymity. [0003] At the same time, Generative Adversarial Networks (GAN) is another popular research direction ...
