Description

Anti-fake transaction system and the method for commerce of tracing to the source of digital art works based on block chain
Technical field
The present invention relates to ether mill block chain fields, more particularly to the anti-fake friendship of tracing to the source of the digital art works based on block chain Easy system and method for commerce.
Background technique
The development of internet has greatly pushed the sharing and propagation of information, passes through shirtsleeve operation, so that it may obtain sea The information of amount, many are gathered around copyrighted works and are just used wantonly under the premise of permitting without obligee, and confusion of encroaching right is caused It grows thickly.However law always lags behind the development of technology, the not known right of obligee is impaired, and works may spread wide, and invade It weighs main body and infringement degree is also difficult to assert, online infringement all lacks effective administer all the time.
A large amount of problems that copyright faces are published for Contemporary Digital artistic work, such as: online infringement is serious, copyright trading is protected Shield measure is out of strength, damages difficulty is big.The reliable anti-fake traceability system of complete set is that the sector is badly in need of, and traditional is anti-fake Traceability system mostly uses centralization memory module, relies on traditional database and is stored, using client end/server end (C/S) Framework, in the architecture, data are stored in center server, and user can be by client to the number stored in the server It modifies operation according to the data in library.In traditional database framework, specified power, user are remained to the control of database Entreat system before database that will carry out authentication to client computer in the access.Since the management of traditional data is based on user What permission was come, therefore, once the safety of authorization is on the hazard, the data in entire database will face leakage, quilt Malicious attack, or even there is the risk lost completely.
The information of traditional database is typically all secret, and data are also by encrypting storage later, and related side can not be clear See data to Chu.Comparatively, information is in island mode, does not have sharing.Each participant holds portion oneself Account book is recorded, can distort or carry out post editing without restriction, information is in desultory dotted presentation, not can guarantee number According to credibility.
The preservation of traditional database is it is also possible to lead to corrupt data.Storage new data will cover legacy data each time, It cannot achieve the permanent reservation of whole historical record datas.
In contrast, block chain such as has decentralization, can be traced, can not distort change at characteristics, the mode of decentralization Become the path of information propagation, it is ensured that the authenticity of data source, while ensure that data can not be tampered or forge.It is based on The technology of block chain can change the propagation path of information completely, fundamentally improve the safety problem of information propagation path.This is System is that a kind of distributing copyright collection based on block chain technology is anti-fake, is traced to the source, the system of transaction.Version is provided for authorship Power protection, copyright trading, the basic functions service such as copyright retrieval, it is intended to be that the art work is anti-fake and anti-using the advantage of block chain Fraud provides new approaches and new method, the artistical intellectual property equity of effective protection.
Summary of the invention
The purpose of the present invention is to overcome the shortcomings of the existing technology, and it is anti-to provide a kind of digital art works based on block chain Puppet is traced to the source transaction system and method for commerce, is realized in web page and ether mill network by the third parties such as web3.js class libraries The interaction of intelligent contract encodes according to the works that the information of copyright generates the whole network unique identification, later believes these The synchronization that the whole network node is carried out in some block chain is recorded in breath, and generates a unique block chain rights certificate, in quilt Original works is taken out when infringement and the block chain rights certificate with timestamp mark goes for the complaint of associated rights appraisal organization, is put down Platform side confirms this works after investigating original works copyright and block chain rights certificate with timestamp provided by you Original copyright can be used legal means and carry out right-safeguarding.
The purpose of the present invention is achieved through the following technical solutions: the digital art works based on block chain are anti-fake to trace back Source transaction system, including Business Logic, data encapsulated layer and interface layer;Business Logic include line module, uploading module, Transaction modules and auction module;Data encapsulated layer includes data write-in encapsulation and data query encapsulation;Interface layer includes user's note Volume interface, account inquiries interface, transaction interface and Transaction Inquiries interface;
Line module logging in and registering for user's;Line module is mainly used for logging in and registering for user, for for the first time The user used, needs to carry out the registration of account, and when registration can be submitted to data on block chain, such as succeeds in registration, then local number The preservation of account information and block chain return information is carried out according to library, in order to encourage everybody using the system, for each new note The user of volume provides certain reward, and someone disorderly brushes in order to prevent.So it is very important for the mailbox of registration user, each Mailbox can only be registered once.
Uploading module is for uploading works;It is exactly that a friendship is initiated in block chain network that user, which initiates a upload function, Easily, the block chain address returned when wherein needing user registration success, due to the block chain address and user name be it is corresponding, because This needs to realize the conversion between user name and block chain address, the operation of as one time database.
Transaction modules are for initiating transaction;User is successfully registered to after account, so that it may carry out block chain data Interactive operation.Each people in need of help initiates a transaction, block chain exactly is removed in the message write-in that the initiation is traded In the middle, after several seconds verifying common recognitions, block chain can return to one message of user, it may be possible to initiate successfully or lose It loses.The initiation of transaction is related to the operation of local data base three times and the operation of a block chain database.
Auction module is used to determine the final whereabouts of auction fund and cargo.Unexpectedly clapping is the system very important one Point, it is related to the whereabouts of final coin number.The premise of completion of an auction is to reach the scheduled date, in the instance objects of Calendar Time can be increased or decreased, with the positive and negative mark for increase and decrease.Since this time format saved is xxx/ Xxx/xxx/xxx, a simple method is exactly to carry out the comparison of character string, if the character string of current time and be recorded in The time character string of database is the same, illustrates that time is up, can settle accounts.Rule of judgment there are two completion of an auction is main, one It is after expiring the time, one is whether auction succeeds.The flowing of fund is equivalent to the operation of a block chain.
Further, data write-in encapsulation function is that the block chain of bottom is supplied to the data write-in interface that developer uses It is packaged;Data query encapsulation function is supplied to the data-query interfaces that developer uses for the block chain of bottom and seals Dress.
Further, data write-in interface includes user's registration interface and transaction interface;Data-query interfaces include account Query interface and Transaction Inquiries interface.
