A method and a system for storing and retrieving media content based on block chain technology

Abstract

The invention relates to the technical field of block chain, which relates to a method and a system for storing and retrieving media content based on block chain technology. The endorsed chain code isobtained from an endorsement module through a block chain network issuing module. After the content is verified to be legal by the endorsement node, the source chain code is issued for the endorsement node. According to the requirements of the creator, the source chain code is generated into a public chain code or an encrypted chain code for distribution. Users can get what they want on each portof the publishing module. The block chain network structure of the invention is a network which is propagated, recorded and identified by point-to-point. The block chain of the invention has the characteristics that the block chain can not be tampered with naturally and can not be repudiated.

Description

technical field [0001] The invention belongs to the technical field of blockchain, and in particular relates to a method and system for storing and retrieving media content based on blockchain technology. It also involves a decentralized media content storage and retrieval method based on the distributed database structure of the block chain. The information publisher is associated with the information content released by the smart contract, and the content creator and the corresponding content creator are accurately retrieved using the block chain technology. Content. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] For a long time, the media industry has been faced with the problem of reasonable reproduction and dissemination of digital content on the Internet. Such problems have resulted in the inability of regulators to confirm and manage information sources, and information creators cannot effec...

AI Technical Summary

Problems solved by technology

[0005] (1) Regulators cannot directly and effectively identify and manage information sources

Due to the huge workload, the management agency cannot detect and intercept the dissemination of illegal information before the information is disseminated, and because of the anonymity of the network, it is difficult for the regulatory agency to trace the publisher and disseminator of the illegal information even if it finds the illegal information

[0006] (2) Creators of media content cannot effectively guarantee that their information enjoys reasonable and legal copyright benefits, and are often easily plagiarized, pirated and illegally copied by others

[0007] (3) The sudden increase of a large amount of homogeneous information puts huge pressure on the storage end of large media platforms, resulting in an increase in the cost of media information transmission and storage

[0009] (5) When the creator of the media content publishes the original content on a single platform, the number of views and visits of the content will be limited, and when the content is published on multiple platforms, due to the different attention of the author on other platforms, resources due to content duplication Waste, but also increase the workload of the author and disperse the concentration of the author's fans

[0011] (1) For normal centralized media, the first layer of supervision is all assisted by the media intelligent system for manual self-audit, and the ports provided to the supervisory agency are often effectively controlled by manual methods such as reporting after the expansion and dissemination of illegal information sources. Leading to the rapid dissemination and duplication of illegal information on the Internet, deleting the illegal information that has already flowed to the Internet has missed the best time for supervision

[0012] (2) Since conventional online media does not have the function of original identification, usually only the original author can complain and give feedback to the media and trace the legal responsibility when others illegally copy and disseminate their original information to a sufficient amount. This traceability process will It takes a long time to stop the infringement of others, and because the infringement has already occurred, it often causes incalculable losses

[0013] (3) There is a large amount of homogeneous information on the existing centralized media, similar information with the same function or purpose, and a large amount of storage and processing on the centralized media has caused the cost of information storage and processing on the centralized media to increase. high

[0014] (4) It is difficult for centralized media to take into account the joint legal responsibility while ensuring the freedom of creative space. In order to provide a creative space with a high degree of freedom, centralized media often relax content review and control, but legally due to The media has stored, processed and disseminated illegal information, so it must also bear corresponding legal responsibilities

[0015] (5) Since the centralized media are relatively independent storage, processing and dissemination systems, the breadth and depth of information dissemination of each media are limited within the scope of the number of users
