Description
Technical field
The invention belongs to block chain technical field more particularly to a kind of media content storages and inspection based on block chain technology
The method and system of rope.Further relate to the media content storage and retrieval of the decentralization based on block chain distributed database structure
Information publisher is associated with the information content that it is issued by intelligent contract, is accurately retrieved using block chain technology by method
To content originator and corresponding content.
Background technique
Currently, the prior art commonly used in the trade is such that
Media industry is faced with always digital content the reasonable copy propagation content on network the problem of for a long time, this
The problem of sample, which just produces regulatory agency and can not confirm, also can not effectively guarantee oneself with management information source, information creator
Information enjoys equity legitimate, while a large amount of homogeneous exploding for information gives the huge pressure of storage end of big media platform
Power, and the audit of media information and its legal liabilities undertaken also allow media platform to add additional workload.
In conclusion problem of the existing technology is:
(1) regulatory agency directly can not effectively confirm and management information source.Huge due to workload, management organization is not
The propagation of illegal information can be found and intercepted before information is not propagated, and since the anonymous form of network leads to regulatory agency i.e.
Make to find that illegal information is also difficult to track the publisher and disseminator of illegal information.
(2) creator of media content can not effectively guarantee that the information of oneself enjoys copyright revenue legitimate, past
It is past to be easy to by other people plagiarisms, pirate and illicit copy.
(3) a large amount of homogeneous exploding for information give the huge pressure of storage end of big media platform, cause media information
Transmission and carrying cost increase.
(4) audit of media information and its legal liabilities undertaken allow media releasing platform increasing the same of workload on foot
When, also take on related legal liabilities.
(5) media content creator publication, can limit to when single platform does original starting the content pageview and
Amount of access is issued in multiple platforms and is caused again in the attention rate difference of other platforms because of the duplicate resource wave of content due to author
Take, also increased the workload of author on foot and has dispersed the bean vermicelli concentration degree of the author.
Solve the difficulty and meaning of above-mentioned technical problem:
(1) normal centralization media, supervision first layer is all voluntarily audited by media intelligent system indirect labor, to prison
It is effective that the port that pipe mechanism provides could often pass through the progress of the manual types such as report after illegal information source is expanded and is propagated
Control, cause illegal information quickly to propagate and replicate in internet in this way, to having flowed to the illegal information of network again
Delete and has had already passed by optimal supervision opportunity.
(2) since the conventional network media does not have original identification function, only authorship is separated at other people under normal conditions
When the original information that method replicated and propagated oneself reaches sufficient amount, it could be complained to media and be fed back and trace law duty
To appoint, this trace back process can continue for an extended period of time the abuse that could prevent other people, and since abuse has occurred and that,
Often result in the loss for being difficult to estimate it.
(3) there are a large amount of homogeneous information on existing centralization media, there is the close information of same function or purposes,
Largely storing and handle on centralization media causes the information storage of centralization media and the upper cost of processing higher and higher.
(4) media of centralization are difficult to take into account while ensuring that writing space is free the related in order to provide of legal liabilities
The higher writing space of one degree of freedom, centralization media often loosen the examination and control of content, but legally due in
Heart media have carried out storage processing to illegal information and have propagated, therefore also to undertake corresponding legal liabilities.
(5) since centralization media are each opposite independent storage processing and broadcasting system, the letter of each media
Breath is propagated breadth and depth and is all confined within the scope of user volume.The breadth and depth that authorship wants to expand information propagation is necessary
It is all uploaded on each media.
