Description
Technical field
The present invention relates to block chain application fields, more particularly, to a kind of data subregion storage based on block chain, look into
Ask method and system.
Background technique
Currently, block chain is a kind of unique way of the encryption currency storing data such as bit coin originally, it is a kind of self reference
Data structure, for storing a large amount of Transaction Informations, every record is orderly chained up from back to front, has open and clear, nothing
Method distorts, facilitates the characteristics of retrospect.Block chain (Blockchain) is a series of organic assembling of existing mature technologies, its reconciliation
The distributed effective record of this progress, and perfect script is provided to support different service logics.In typical block chain
In system, data are that unit is generated and stored, and is linked to be chain type (chain) data knot sequentially in time with block (block)
Structure.All nodes participate in the data verification of block catenary system, storage and maintenance jointly.The creation of new block need to usually obtain the whole network
The confirmation of most (quantity depends on different common recognition mechanism) nodes, and realize that the whole network is synchronous to each node broadcasts, later cannot
Change is deleted.But the information between node all on existing block chain is all transparent, can be obtained between each other
Whole data are taken, then data-privacy becomes everybody very concern in present big data era, are realized between node
Authorization access, trusty check call the information inside block just to seem most important.
Summary of the invention
The present invention is to overcome defect described in the above-mentioned prior art, and the node of block chain is carried out according to its corresponding operation
Classify, cooperates between all types of nodes and complete the operation such as to encrypt, authorize and know together, a kind of number based on block chain is provided
According to subregion storage, querying method and system.
In order to solve the above technical problems, technical scheme is as follows:
A kind of data subregion storage method based on block chain, comprising the following steps:
S1. the node type in block chain is determined;
S2. judge whether node data contains private data, if it is, entering step S4, otherwise enter step S3;
S3. node data is broadcasted to block chain the whole network node, enters step S7;
S4. common recognition verifying is carried out to the private data part of node, the private data is stored in node;
S5. private data is encrypted;
S6. encryption information is broadcasted to the whole network node;
S7. block chain the whole network common recognition node carries out common recognition verifying;
S8. node data is added in the block of region chain and is incorporated on chain.
The principle of above-mentioned storage method is, classifies first to the information to be uploaded, and existing for non-privacy information
There is the processing mode of information consistent, data content broadcast to the whole network node is directly subjected to common recognition verifying;And for needing to protect
Private data, then first data can be broadcasted in this subregion, common recognition verifying is carried out in this subregion, be verified after will
Content is stored to the database of each node of subregion, and data content is then carried out hash encryption, then by hash value broadcast to
The whole network block chain carries out common recognition verifying in all nodes.
Further, detailed process is as follows by the step S1:
Determined in block chain and need to participate in the block chain node of subregion, the block chain link point is judged and minute
Class, to each block chain node setting label, for being global common recognition node, subregion common recognition node or synchronous section by node identification
Point.
By information content broadcast to the whole network node between global node and synchronization node, and then basis is partitioned nodes
It is no to judge whether to encrypt after directly broadcasting or store to partitioned nodes containing private data, then hash value is broadcasted to the whole network section
Point;
During common recognition, global node carries out common recognition verifying to the block information of all nodes, wherein common recognition verifying
Information includes the hash value of whole nodes all visible non-privacy information and the privacy information in partitioned nodes;And partitioned nodes are then
The common recognition verifying of two steps need to be carried out, in the first step, common recognition verifying is carried out to the nodal information in subregion and information is stored in this
In the database of node;In second step, after private data is carried out HASH encryption broadcast to the whole network node, to hash value into
Row common recognition verifying;Synchronization node is not involved in common recognition process.
Further, the global common recognition node and synchronization node do not include private data.
Further, the encryption of the step S5 is HASH encryption, and the encryption information of the step S6 is served as reasons
The HASH code that HASH encryption in step S5 generates.
Further, detailed process is as follows by the step S8:
Node is locally creating new block, writes data into block body, obtains effective HASH code of existing block and be written
New block is added in block chain in the information of block head.
Further, the common recognition verifying in the step S4 and S7 is specifically, between nodes multiple in block chain
It carries out common recognition algorithm to calculate, the data for participating in formula verifying is made to be updated to last state.
A kind of data subregion querying method based on block chain, comprising the following steps:
S101. inquiry request is sent to block chain node;
Whether the node data that S102. block chain node judges that inquiry request is directed toward is private data, if it is, into
Step S104, otherwise enters step S103;
S103. block chain the whole network node carries out carrying out common recognition verifying to inquiry request, enters step S106;
S104. the node that inquiry request is directed toward authorizes inquiry request, generates authorization message;
S105. by authorization message in subregion common recognition node common recognition verifying;
S106. inquiry operation is carried out, node data specified by inquiry request is read;
S107. query process information is added in block chain.
The characteristics of above-mentioned querying method, is, for globally visible data, all nodes can be provided by block chain
Interface check data;For private data, node of the outside access person first into block chain issues request, data owner
Request is judged, visitor can just check corresponding data after being authorized.
A kind of block chain data system, specifically includes: overall situation common recognition node, subregion common recognition node and synchronization node;
The global common recognition node is specifically, for carrying out common recognition verifying to the block information of all nodes;
The subregion common recognition node is specifically, for carrying out common recognition verifying to the nodal information in subregion and storing information
In the database of this node;
The synchronization node is specifically, be used to participate in the transmission of data comprising upload and simultaneously operating.
Compared with prior art, the beneficial effect of technical solution of the present invention is:
Node-classification in block chain is global common recognition node, subregion common recognition node and synchronization node by the present invention, is passed through
It limits node and distributes the storage of information subregion and the concrete operations checked, each node realized in block chain network are divided
Area and classification;Storage method of the invention is the different storage scheme of the design of node of different subregions, will pass through the transaction of verifying
The range of the subregion common recognition node of subregion where the memory node of data is limited in global common recognition node and each transaction data
It is interior, cooperate corresponding querying method to make the spread scope of the transaction data by verifying be substantially reduced, it is hidden to improve data
Private protecting effect.
Compared with the block chain technology of existing realization data-privacy protection, there is no the wind that transaction summarization is arbitrarily propagated
Danger does not need the time-consuming institute increased trade confirmation time for undertaking decryption oprerations yet.
