Description
Technical field
The invention belongs to block chain technical fields, look into particular to a kind of gateway information based on block chain is shared
Ask method and system.
Background technique
What this part provided is only background information relevant to the disclosure, is not necessarily the prior art.
Block chain is a kind of chained record for being sequentially in time composed data block in such a way that sequence is connected
Structure, as the Floor layer Technology of all kinds of digital cash such as bit coin, block chain records all friendships similar to a database account book
Easily record, because safely and conveniently characteristic, block chain technology have gradually obtained the attention of multiple industries such as science and technology, finance, business for it
And use, still, block chain technology in the prior art remain in actual application many technical problem and
Drawback is mainly reflected in:
On the one hand, in traditional block chain book keeping operation mode, in order to ensure can not distorting for distributed account book and data, whenever
It participates in node to generate transaction record or upload clear data, each node requires to update and save the pair of a information record
This, in other words, the transaction record and clear data copy of every other node need to be stored by participating in node, this will lead to user's
Privacy is unable to get effective guarantee, meanwhile, each node indistinguishably synchronizes plaintext data file, often leads to integral sharing
The process performance and efficiency of network are gradually deteriorated.
On the other hand, the process that local clear data is transferred to block platform chain or other participation nodes by user is cumbersome,
And higher cost.
It can be seen that block chain technical user privacy in the prior art is poor, the transmission of platform processes low efficiency, data is numerous
It is trivial, operating cost is high etc., and various drawbacks are just becoming technical problem urgently to be resolved.
Summary of the invention
The present invention provides a kind of gateway information sharing query method and system based on block chain, it is therefore an objective at least solve
One of problems of the prior art are stated, which is achieved through the following technical solutions:
A kind of gateway information sharing query method based on block chain, comprising:
S1: initial data is generated；
S2: operation system database is written into the clear data of the initial data；
S3: the data gateway that installation and deployment are located locally carries out node initializing；
S4: the data gateway carries out data conversion treatment to the clear data；
S5: the clear data that conversion process is crossed is stored to the private data library being located locally；
S6: with polygon ledger design method, by common recognition mechanism by the cryptographic Hash of the clear data without selectively wide
It is multicast to interdependent node on chain.
Further, the gateway information sharing query method based on block chain further include:
S7: data are obtained by transport layer security protocol channel, are calculated after splicing each column data by sha256 algorithm
Digest value.
Further, the gateway information sharing query method based on block chain further include:
S8: whether the digest value that contrast conting obtains is consistent with the cryptographic Hash inquired, if comparison result is consistent, verifies
Pass through, storing data.
S9: export data sheet checks the clear data in the private data library, uses data.
Further, in above-mentioned steps S1, the initial data is the order data of operation system, the order data packet
Include order number, product name, price and timestamp, wherein the order number and timestamp of every data constitute the unique of the data
Inquire major key.
Further, when inquiry business system initiates inquiry request, inquiry data gateway is read from the private data library
The clear data and comparison result are transferred to issuer after the completion of comparison by the clear data.
Further, the clear data can not be distorted.
Further, in such a way that interface push, interface call, database direct transfers or document analysis, by the plaintext
Data are transferred to the data gateway.
In addition, the present invention also provides a kind of bases applied to the above-mentioned gateway information sharing query method based on block chain
Inquiry system is shared in the gateway information of block chain, the gateway information based on block chain shares inquiry system and includes:
Operation system database, for being written and storing initial data；
Private data library, for storing the clear data of the initial data；
Data gateway, for connecting the operation system database and the private data library, carry out data conversion and

The mode of biography or document analysis, is transferred to the data gateway for the clear data.
In addition, referring to figures 1-4, it is shared applied to the above-mentioned gateway information based on block chain that the present invention also provides a kind of
The gateway information based on block chain of querying method shares inquiry system, the shared inquiry system of the gateway information based on block chain
System includes:
Operation system database, for being written and storing initial data；
Private data library, for storing the clear data of the initial data；
Data gateway, for connecting the operation system database and the private data library, carry out data conversion and
Transmission.
According to one embodiment of present invention, referring to figures 1-4, distributed account book platform, the distribution account book platform
It is connected with the data gateway, it can be by the cryptographic Hash of the clear data without other sections being selectively broadcast on platform
Point.
According to one embodiment of present invention, referring to figures 1-4, the distributed account book platform in the present invention, is to answer
Block platform chain for the interactive operation scene between interbank or bank and its user, it is preferable that use Corda distribution account
This platform, the platform have a technical advantage of block chain, such as the features such as UTXO model and intelligent contract, but its towards be
Interactive operation scene between interbank or bank and its commercial user, and not all user all may participate in.
