Abstract
The invention discloses a kind of secure data method of commerce issued based on block chain token, are related to block chain intelligence contract, token issues field.In this method, data set provider is to carry out the storage of data under chain and the mark of data is recorded on the intelligent contract of block chain, data purchaser carries out the purchase of token by block chain intelligence contract, and the acquisition of data is transmitted by way of token authentication under chain.Present invention combination block chain solves the safety of data trade, Creditability Problems, guarantees the consistency of data exchange by way of block chain issues token, avoids the problem of either party denies.
Description
Technical field
The present invention relates to block chain intelligence contract, tokens to issue field, more particularly to one kind is issued based on block chain token
Secure data method of commerce.
Background technique
Intelligent contract (English: Smart Contract) is that one kind is intended to that conjunction is propagated, verified or executed in a manner of information-based
Same computer protocol.The permission of intelligent contract carries out credible transaction in no third-party situation, these transaction it is traceable and
It is irreversible.
In computerese, token represents the object for executing the right of certain operations, can be tested by token visitor
The identity of visitor is demonstrate,proved, and identifies the access authority of visitor: time restriction, access object and operating right etc. according to token
Deng by way of token, we very easily resource for oneself can carry out effective protection.
A kind of secure data method of commerce issued based on block chain token, which is combined with block chain intelligence contract, to usurp
It is modified and the characteristics of executed by force according to set contract and the advantages of token can be carried out the control of effective permission and one kind for getting
Secure data method of commerce.
The existing main deficiency of technology is that data trade record does not have authority and trust guarantee, is played if a side exists
Bad situation, interests loss side provides believable evidence without normal direction third party authoritative institution, so that oneself can not be protected well
Interests.
Summary of the invention
In view of the deficiencies of the prior art, it is an object of the present invention to provide a kind of secure datas issued based on block chain token
Method of commerce.
The purpose of the present invention is what is be achieved through the following technical solutions: a kind of secure data issued based on block chain token
Method of commerce, in this method, data set provider storing data under chain, and the mark of data is stored in block chain intelligence contract
On, this method specifically comprises the following steps:
(1) freeze the fund for needing to pay data set provider on data purchaser buyer to block chain；
(2) token field that data set provider needs data purchaser is signed, and is uploaded on intelligent contract, intelligence
Energy contract verifies signature, and if the verification passes, then fund is given to token provider according to given logical by intelligent contract,
Otherwise, this time token issues failure；
(3) this token issued is obtained on data purchaser to block chain, and with this by block chain intelligence contract
The token issued goes to obtain data；
(4) token that carries when data set provider verify data buyer obtains data, only reasonable token just can be with
Data are transmitted to other side, otherwise refusal sends data；
Further, data set provider needs onto block chain intelligence contract to register the rule of oneself, the money including needs
Gold, time, access times information.
Further, data purchaser has freezed fund, and notification data supplier is needed to go to complete the signature step of token.
Further, efficiency is issued in order to improve token, after data set provider signs and gets the funds, needs to lead
The token is obtained on dynamic notification data buyer to block chain intelligence contract.
Further, it for data set provider, needs that permission is arranged to all data access, it is only reasonable to enable
Board can just delegate power to access.
Beneficial effects of the present invention are as follows:
Present invention combination block chain solves the safety of data trade, Creditability Problems, and the shape of token is issued by block chain
Formula guarantees the consistency of data exchange, avoids the problem of either party denies.
Detailed description of the invention
Fig. 1 is a kind of flow chart of secure data method of commerce issued based on block chain token.
Specific embodiment
Below according to the drawings and specific embodiments the present invention is described in detail, the objects and effects of the present invention will become brighter
It is aobvious.
As shown in Figure 1, a kind of secure data method of commerce issued based on block chain token, in this method, data are provided
Person's storing data under chain, and the mark of data is stored on block chain intelligence contract, this method specifically comprises the following steps:
(1) freeze the fund for needing to pay data set provider on data purchaser buyer to block chain；
(2) token field that data set provider needs data purchaser is signed, and is uploaded on intelligent contract, intelligence
Energy contract verifies signature, and if the verification passes, then fund is given to token provider according to given logical by intelligent contract,
Otherwise, this time token issues failure；
(3) this token issued is obtained on data purchaser to block chain, and with this by block chain intelligence contract
The token issued goes to obtain data；
(4) token that carries when data set provider verify data buyer obtains data, only reasonable token just can be with
Data are transmitted to other side, otherwise refusal sends data；
Preferably, data set provider needs onto block chain intelligence contract to register the rule of oneself, fund including needs,
Time, access times information.
Preferably, data purchaser has freezed fund, and notification data supplier is needed to go to complete the signature step of token.
Preferably, efficiency is issued in order to improve token, after data set provider signs and gets the funds, needed actively
The token is obtained on notification data buyer to block chain intelligence contract.
For data set provider, need that permission, only reasonable token is arranged to all data access
It can just delegate power to access.
