Step S10, receive terminal transmission to the operation requests of storing data in block chain when, obtain the operation
Request corresponding keyword.
Block data platform receive terminal transmission to the operation requests of storing data in block chain when, wherein behaviour
Making request can be data update request, data modification request and data removal request etc.；Block data platform obtains operation and asks
Seek corresponding keyword Key.
It should be added that the triggering mode of operation requests is not especially limited in the application, that is, operation requests can
Being triggered manually by user, for example, then user inputs " change of xxx business datum " at the terminal clicks presetting in terminal
Key, trigger action request, block data platform receive operation requests, and obtain the user's input carried in operation requests
" xxx business " is used as the corresponding keyword of the operation requests by " xxx business ", block data platform；Alternatively, operation requests may be used also
To be automatic trigger, for example, operation requests trigger condition is being arranged in user in block data platform in advance: in storing data
Automatic trigger data update request when update；When block data detection of platform to storing data updates, block data platform is certainly
Dynamic trigger data updates request, and data are updated type of service that request carries etc. as data and update request by block data platform

Operation requests in the present embodiment correspond to keyword include: data type, affiliated person mark, type of service and/or
Service identification, for example, data type includes business datum, organization information data and message data etc., different types of data are taken
It is identified with different data types, if business datum is with " 001 " beginning, organization information data are with " 002 " beginning.
Each data are stored in block chain and all there is corresponding affiliated person's mark, according to the corresponding affiliated person of each data
Mark, it may be determined that the affiliated person of data；Type of service is arranged according to specific needs, such as may be configured as invoice type, order
Type and buying and selling of commodities type etc.；Under specific business scenario, the service identification of each data all existence anduniquess, but it is multiple
There may be identical service identifications for business scenario.Therefore, to find a unique data in block chain, operation is asked
The data type for including in keyword, affiliated person mark, one in type of service and service identification or more can be carried by asking
It is a.That is, the keyword Key of each data can be connected by fixed separator in block chain, which can be "-",
", " etc., for example, target data: 1523 (data type a, affiliated person mark b, type of service c, service identification d).
Step S20 inquires the data stored in the block chain, obtains the target data with the keyword match, and
Judge that the terminal corresponds to the operating right whether user has the target data.
After block data platform gets keyword, according to the number stored in the keyword query block chain of acquisition
According to specifically, comprising:
The corresponding preset keyword of each data stored in the keyword and the block chain is compared step a,
Using preset keyword data identical with the keyword as the first data；
Step b sends prompt information to the terminal, with prompt when the quantity of first data is no less than two
The terminal corresponds to user and inputs new keyword；
Step c receives the new keyword that the terminal is sent, and the new keyword is corresponding with first data
Preset keyword be compared, until get the corresponding target data of the operation requests.
That is, block data platform carries out the keyword preset keyword corresponding with each data of storage in operation requests
It compares, block data platform is using the identical data of preset keyword keyword corresponding with operation requests as the first data；Then,
Block data platform obtains the data amount check of the first data；When the quantity of the first data is no less than two, block data platform
Prompt information is sent to terminal, user is corresponded to prompt terminal and inputs new keyword；Block data platform receives terminal and sends
New keyword, new keyword preset keyword corresponding with the first data is compared, until getting operation and asking
Seek corresponding unique objects data.
For example, block data platform obtains the data according to keyword in block chain when keyword is data type
The corresponding total data of type；When the data volume of the acquisition is multiple, terminal when block data platform sends prompt information, eventually
End subscriber inputs new keyword: service identification, and service identification is sent to block data platform by terminal, and block data platform is pressed
New keyword: service identification filters out the corresponding target data of operation requests from multiple data.
After block data platform gets target data, block data platform needs to judge that the terminal corresponds to user and is
The no operating right having to target data, to determine whether to execute the operation requests, wherein block data platform carries out permission
The step of judgement includes:
The target data is back to terminal by block data platform, and terminal encrypts target data using its private key,
And terminal signs encrypted target data, the target data after being signed, terminal is by the target data after signature
Return to block data platform.Public key corresponding with the private key is stored in block chain.When block data platform receives
After encrypted target data, using the public key decryptions target data.It can be with successful decryption target data, then according to the public key
Block data platform determines that terminal corresponds to the operating right that user has target data；Number of targets cannot be decrypted according to the public key
According to then block data platform determines that terminal corresponds to user without the operating right to target data.
It should be added that Encryption Algorithm includes but is not limited to MD5 and hash algorithm.In the present embodiment, each
There is corresponding public private key pair in user, public key is stored in the intelligent contract of block chain, and private key is by terminal storage.In addition, block
Chain can also correspond to different private keys according to the difference of operation requests, in the public private key pair of user, there are a public key and with
The corresponding multiple sub- private keys of the public key.Such as, after terminal data update the corresponding sub- private key encryption target data of update of request, if
Block chain uses public key can be with the successful decryption target data, then block data platform judges that terminal corresponds to user and has update mesh
Mark the renewal authority of data.
Step S30, when the terminal, which corresponds to user, has the operating right of the target data, by the operation requests
Handle the target data.
Block data platform determine terminal correspond to user have target data operating right when, block data platform is pressed
Operation requests processing target data, for example, operation requests are to update operation requests, block data platform is according to update operation requests
Update target data.
When block chain distributed data platform receives operation requests in the present embodiment, the corresponding number of operation requests is obtained
According to type, affiliated person mark, type of service and/or service identification, according to data type, the affiliated person mark, industry got
Service type and/or service identification inquire the data stored in block chain, realize multidimensional data query operation, improve
The efficiency of data query in block chain.
Further, on the basis of first embodiment of the invention, propose that the present invention is based on the data managements of block chain
The second embodiment of method.
The present embodiment be in first embodiment after step S30 the step of, block data platform will operate in the present embodiment
Information is recorded, to facilitate backtracking and analysis to storing data in block chain, specifically, comprising:
Step S40 obtains the corresponding processing letter of the target data when detecting that the target data processing is completed
Breath.
At the end of target data operation, target data is added an operation label, block data by block data platform
When detection of platform is to the operation label, block data platform determines that target data processing is completed, at this point, block data platform obtains
The operation information of target data, wherein processing information includes: operating time point, operation user identifier and action type, so that area
Operation information is added to corresponding target data by block data platform, specifically:
Step S50 stores the Value value and the target data association using the processing information as Value value
Into the block chain.
The processing information that block data platform will acquire is stored as Value value, and by Value value and target data association
Into block chain, that is, Value value only has recorded and keyword corresponding data, root in current block chain Key-Value database
It can not judge whether the target data is newly-increased data according to Value value, the data being still modified can not also judge to modify
Whom the modification user for the data crossed is, block data platform is using operation information as Value value in the present embodiment, so that block
Data traceability in chain is more accurate, meanwhile, block data platform can also carry out target data analysis according to Value value.
Further, on the basis of the above embodiments, propose that the present invention is based on the data managing methods of block chain
3rd embodiment.
The present embodiment is the refinement of step S20 in first embodiment, and two kinds are shown in particular in the present embodiment and judges terminal
Whether corresponding user has the mode of target data operating right, implementation one: block chain carries out user according to user's signature
Permission judgement, that is,
The target data is fed back to the terminal by step S21, so that the terminal uses private key to the number of targets
According to progress cryptographic operation.
Target data is fed back to terminal by block data platform, so that terminal carries out encryption behaviour to target data using private key
Make, terminal simultaneously signs to encrypted target data, the target data after being signed, and terminal is by the number of targets after signature
According to returning to block data platform.The digital signature of terminal in the present embodiment, that is, rivest, shamir, adelman needs together when in use
Shi Yongyou public key and private key, public key is corresponding with private key, if having used public key in the ciphering process to data, only has
It could be decrypted using corresponding private key., whereas if having used private key when encrypting to data, also only use
Corresponding public key could be decrypted.
Step S22 is determined when receiving the encrypted target data that the terminal is sent by default intelligent contract
Public key is decrypted, and operation is decrypted to the target data by the public key.
When block data platform receives the encrypted target data that terminal is sent, block data platform is by default intelligence
(default intelligence contract is the pre-set computer program operated on reproducible, shared account book to contract, can handle letter
Breath receives, storage and transmission are worth) determine decryption public key, and operation is decrypted to target data by public key.
Step S23 determines that the terminal corresponds to user with the target data in the target data successful decryption
Operating right.
When block data platform is to target data successful decryption, block data platform determines that terminal corresponds to user with institute
State the operating right of target data.
Implementation two: terminal encrypt target data and timestamp together when cryptographic operation, that is,
The target data is fed back to the terminal by step S24, for the terminal by the timestamp of current time and
Target data carries out cryptographic operation together.
Target data is fed back to terminal by block data platform, so that terminal is by the timestamp and target data of current time
Cryptographic operation is carried out together.That is, the present embodiment, when encrypting to target data, terminal is added together with timestamp using target data
It is close, it is to be understood that the time point of terminal encryption target data can be determined by timestamp.
Step S25 carries out the target data when receiving the encrypted target data that the terminal is sent
Decryption oprerations obtain the timestamp, by the timestamp calculate target data described in the terminal encryption time and it is current when
Between time interval.
When block data platform receives the encrypted target data that terminal is sent, block data platform is to target
