Abstract
The invention discloses a data evidence storing method based on a block chain, which comprises the following steps: a. receiving an uploading storage request of electronic data storage certificate, generating a global unique identifier, and performing hash operation to obtain a hash value C; b. sending the global unique identifier and the hash value to a message queue center as messages, and feeding back the global unique identifier of the electronic data certificate to an uploading storage requester of the electronic data certificate; c. deploying a plurality of modules connected with the message queue center and used for acquiring messages, wherein the modules used for acquiring messages acquire message data from the message queue center in parallel and call an interface of a block chain network to store the data to a block chain; d. and C, inquiring whether the stored global unique identifier and the hash value C of the electronic data certificate exist in the block chain, if so, finishing storage, if not, putting the global unique identifier and the hash value C of the electronic data certificate into a message queue center again, and repeating the step C.
Description
Technical field
The present invention relates to data to deposit card, tracing technology field, and especially a kind of data based on block chain deposit card method.
Background technique
Traditional data deposit card and data tracing technology is to be stored based on database to file, traditional data storage
Mode can only save newest state data memory, not have not modifiable characteristic, not have that data deposit card and data are traced to the source
Characteristic, the purpose that data deposit card and data are traced to the source can not be really achieved.
Summary of the invention
To solve problems of the prior art, the present invention provides a kind of data based on block chain to deposit card method.
The technical solution adopted by the present invention is that:
A kind of data based on block chain deposit card method, include the following steps:
A, the upload storage request that electronic data deposits card is received, a globally unique identifier is generated, obtains electronic data
It deposits unique number, the host MAC address for issuing request and the time for demonstrate,proving locating hard disk, meanwhile, card and hard is deposited to the electronic data
The unique number of disk, the host MAC address for issuing request and time carry out Hash operation, obtain cryptographic Hash C；
B, it is used as message to be sent to message queue center together the obtained globally unique identifier of step a and cryptographic Hash,
Also, the globally unique identifier that the electronic data deposits card is fed back into the upload storage requesting party that the electronic data deposits card；
C, dispose it is multiple connect with message queue center be used to obtain the modules of message, for obtain the module of message from
Message data is obtained in message queue center parallel, and the interface of block chain network is called to store data to block chain；
D, the electronic data that storage is inquired in block chain, which deposits the globally unique identifier of card and cryptographic Hash C, whether there is,
As existed, then completes to store, if it does not exist, electronic data is deposited into the globally unique identifier of card and cryptographic Hash C is reentered into and disappears
Queue center is ceased, step c is repeated.
Preferably, each step data circulation that electronic data is deposited to the upload storage requesting party of card is all stored in block link network
Network carries out depositing card.
Preferably, in step a, cryptographic Hash C is obtained, is specifically included:
Unique number, the host MAC address for issuing request and time that the electronic data of upload deposits card and hard disk are carried out
Hash operation is primary, obtains cryptographic Hash A, and cryptographic Hash A and a string of random data are then merged into value B, then again for value B
It carries out Hash operation and obtains cryptographic Hash C.
Preferably, a string of random data are generated by Java Virtual Machine is included.
Preferably, the Hash operation uses MD5 algorithm.
The beneficial effects of the present invention are:
1, based on block chain, each step data circulation of system is all stored in block chain network and carries out depositing card；System
The data that user submits are stored in block chain network by system, are equally stored data in block chain after first step operation and are deposited
Card, until the end of whole flow process, all data can all deposit card on block chain, including the historical data changed repeatedly,
Thus very good solution data deposit card and data are traced to the source problem, in this way play good effect to the management of data.
2, the present invention by electronic data deposit card and hard disk unique number, issue request host MAC address and the time into
Row Hash operation, obtains cryptographic Hash, and much information and electronic data are deposited card correlating validation, substantially increase the anti-fake energy of data
Power.
3, the present invention carries out multiple Hash to data, and random number is added, and further increases and pushes away original according to hash value come counter
The safety of beginning data.
4, the present invention using it is asynchronous storage arrive block chain, the parallel processing capability of system is greatly improved, in general if
Using the method for synchronization, block chain technical performances many at present is not that very well, encountering high concurrent request cannot deal with.
5, message queue, it is ensured that data one establish a capital storage into block, and block chain, may in high concurrent at present
Be not it is particularly stable, have the case where probability of very little will appear request processing failure, lead to data storage failure, and the present invention is very
Solves this problem well.
6, the present invention uses multiple hash algorithm, not only guarantees that former data do not leak, it is ensured that same data storing frequencies
It does not leak, reply high concurrent request is reached by the decoupling of message queue；And pass through the data of concurrent processing message queue, guarantee
Data quick storage is into block chain；It, also can be again because message queue data are not lost and even if exception occurs in block chain network
It is secondary to store to block chain network.It can not be forged using block chain, the characteristic that can not be distorted solves the problems, such as electronic data security,
Guarantee the validity of electronic data.All nodes save complete data copy in block chain, also effectively avoid center
Change risk.
Specific embodiment
The following describes the present invention in detail with reference to examples.
