Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description is made with reference to the accompanying drawings and specific embodiments.
The invention provides a data processing method aiming at the problem that questionnaire data in the prior art is lack of public confidence, as shown in fig. 1, comprising the following steps:
step 11: acquiring questionnaire data to be processed;
step 12: and calling an intelligent contract on the block chain, and cleaning the questionnaire data to be processed.
The data processing method provided by the embodiment of the invention obtains questionnaire data to be processed; calling an intelligent contract on a block chain, and cleaning the questionnaire data to be processed; the method can ensure the tamper resistance, traceability and open transparency of the data processing process, greatly improve the public credibility of the questionnaire data, and well solve the problem that the questionnaire data in the prior art is lack of public credibility.
The intelligent contract on the calling block chain is used for cleaning the questionnaire data to be processed, and the intelligent contract comprises: and calling the intelligent contract on the block chain according to the account address and the transaction hash value of the intelligent contract, and cleaning the questionnaire data to be processed.
In the embodiment of the present invention, the invoking an intelligent contract on a block chain to perform cleaning processing on the to-be-processed questionnaire data includes: calling an intelligent contract on a block chain, and authenticating the questionnaire data to be processed; if the authentication is passed, performing questionnaire recording operation on the questionnaire data to be processed, and adding a piece of transaction record information in the block chain; and if the authentication is not passed, deleting the questionnaire data to be processed. The authentication includes authentication of an operator corresponding to the questionnaire data to be processed, and specifically, the authentication may include identity authentication and/or authority authentication of the operator corresponding to the questionnaire data to be processed.
Specifically, the calling an intelligent contract on the block chain to authenticate the questionnaire data to be processed includes: calling an intelligent contract on a block chain, and judging whether the identity of the questionnaire data to be processed is unique, whether the generation position of the questionnaire data to be processed is matched with a preset geographic position, and whether the content of the questionnaire data to be processed meets a preset reverse verification condition; if yes, determining that the authentication is passed; if not, determining that the authentication is not passed.
Can also be: the calling of the intelligent contract on the block chain to authenticate the questionnaire data to be processed comprises the following steps: calling an intelligent contract on a block chain, and judging whether an identity of an operator corresponding to the questionnaire data to be processed is unique, whether a geographic position where the operator is located is matched with a preset geographic position, and whether a state when the operator fills in the questionnaire is matched with a preset state; if yes, determining that the authentication is passed; if not, determining that the authentication is not passed.
More specifically, the step of calling an intelligent contract on the block chain to determine whether the content of the questionnaire data to be processed meets a preset reverse validation condition includes: acquiring whether the filling content of the questionnaire data to be processed for the preset forward question is opposite to the filling content of the corresponding preset reverse question; if so, determining that the content of the questionnaire data to be processed meets a preset reverse verification condition; if not, determining that the content of the questionnaire data to be processed does not meet the preset reverse verification condition.
Correspondingly, the aforementioned invoking of the intelligent contract on the block chain, and determining whether a state of the questionnaire filled by the operator corresponding to the questionnaire data to be processed matches a preset state, may include: acquiring whether the filling content of the operator for the preset forward question is opposite to the filling content of the corresponding preset reverse question; if yes, determining that the state of the operator when filling in the questionnaire is matched with a preset state; and if not, determining that the state of the operator when filling in the questionnaire is not matched with the preset state.
The preset state may be a state in which the operator answers the question carefully (fills in the questionnaire carefully).
Further, before obtaining the questionnaire data to be processed, the method further comprises: constructing the intelligent contract; deploying the smart contracts on the blockchain.
Further, when the intelligent contract is deployed on the blockchain, the method further includes: and generating the account address and the transaction hash value of the intelligent contract.
After the intelligent contract on the calling block chain is used for cleaning the questionnaire data to be processed, the method further comprises the following steps: obtaining effective questionnaire data according to the cleaned questionnaire data to be processed; and storing the effective questionnaire data into a preset database.
Further, in order to link all the massive questionnaire data as much as possible, after obtaining valid questionnaire data according to the questionnaire data to be processed after the cleaning processing, the method further includes: generating corresponding abstract information and data index information according to the effective questionnaire data; and storing the summary information and the data index information to a block chain.
The data processing method provided by the embodiment of the invention is further explained below.
Aiming at the technical problems, a scheme which can be trusted by multiple parties is needed to be adopted to collect the questionnaire, and the data source and other information are stored in a public and safe manner; considering that the block chain technology is firstly used for a bit currency system, the block chain technology is a distributed account book, has non-tamper property and is suitable for storing transaction records; the intelligent contract can be seen as a section of program code stored and operated on a block chain, is an activity rule and a related convention which are commonly recognized by related parties participating in a certain activity, and the rule and the convention are expressed in a code mode and are put into the block chain for execution; moreover, smart contracts, once agreed upon and placed on the blockchain, are also transparent to all active participants and unalterable. Intelligent contract execution procedures, status, input and output data are also recorded in the blockchain and are not alterable, transparent to all active participants.
Therefore, the traceability of the block chain is realized, the characteristic of difficult tampering is in line with the requirement, and the intelligent contract technology also provides a convenient implementation way for inquiring the winding set. However, the questionnaire collection is implemented by using a block chain, and has the following defects:
1. the national satisfaction questionnaire survey has huge questionnaires, and a large number of invalid questionnaires exist, such as repeated questionnaires and fake questionnaires, and the invalid questionnaires have great influence on the data analysis and the correctness of conclusion.
2. Due to the characteristics of the block chain technology, the efficiency is low when data is synchronized in the p2p network (peer-to-peer network) in the whole network, and the data is not suitable for storing larger data. Therefore, the massive questionnaire data cannot be linked up in its entirety.
In view of the above technical problems and these drawbacks, an embodiment of the present invention provides a data processing method, mainly relating to the following two aspects:
1. for the defect of the presence of invalid questionnaires: the embodiment of the invention adopts an intelligent contract technology, is deployed at each node in a block chain, cleans invalid questionnaire data and realizes the tamper resistance of the valid questionnaire data.
2. Aiming at the defect that massive questionnaire data is too large and all links cannot be linked: the embodiment of the invention adopts an address mapping mode, stores the original questionnaire data in a preset database (such as a traditional database), and stores the database address mapping (data index information) and the summary information in a block chain.
The method comprises the following specific steps:
firstly, questionnaire data processing is carried out by utilizing intelligent contracts
1. Constructing an intelligent contract female parent (the intelligent contract comprises the functions of questionnaire cleaning, questionnaire query, questionnaire authorization, questionnaire storage and the like), deploying the intelligent contract female parent on a block chain, and automatically generating and returning an account address and a transaction Hash (Hash) value of the intelligent contract female parent when the block chain is deployed; the deployed intelligent contract master needs to be confirmed by the block chain to be identified and then recorded in the block chain, and the intelligent contract master is transparent and unchangeable. Specifically, the "confirmation via blockchain to obtain consensus" may be that the node on the blockchain confirms the normalization of the syntax of the intelligent contract, the call authority of the caller, and the like.
The intelligent contract parent specifies the execution process and the mode method of questionnaire cleaning, and defines the data structure related to the execution process of the mode method.
The "deploying the intelligent contract parent on the blockchain" may specifically be: connecting to a preset node (a specific node) on a P2P network where a blockchain is located through a blockchain client or an Application Program Interface (API) on a local server, and authenticating through the node; calling an intelligent contract deployment script on the node, deploying an intelligent contract to the node, and pushing the intelligent contract to other nearby nodes by the node; and (4) each node on the block chain respectively verifies and deploys locally the contract, and propagates the contract to other nodes nearby each node, and finally the whole network deployment is realized.
2. After the intelligent contract is deployed, the process of calling the intelligent contract by the client can be as shown in fig. 2;
specifically, the flow of implementing the intelligent contract in the embodiment of the present invention may be as shown in fig. 3 (the operator takes a patient in a hospital as an example), and after logging in the questionnaire system, the patient submits a questionnaire; then the questionnaire system calls a login authentication method in the intelligent contract on the block chain to authenticate the identity and the authority of the logged-in patient:
(1) judging whether the ID filled by the patient is unique when the questionnaire is launched; if the position is unique, entering the geographic position matching of the patient (namely entering (2)), and if not, ending the process;
(2) judging whether the geographic position of the patient is in accordance with the geographic position of the hospital when the questionnaire is launched; if the answer is not the same, namely the answers asked by the patient in different modes aiming at the same question are not uniform, the patient questionnaire does not pass through a reverse question verification link, namely the patient questionnaire does not accord with the preset reverse verification condition; if not, the process is ended;
(3) judging whether the patient answers seriously according to the preset reverse question of the questionnaire, and if so, recording the questionnaire (namely, entering (4)); if not, the process is ended;
(4) executing a record questionnaire, and adding block chain transaction questionnaire records; specifically, a new transaction record may be added to the blockchain transaction list.
Second, the address mapping and summary information uplink
1. As in fig. 4, the valid questionnaire data is saved in a traditional database (i.e., the delicatessen database in fig. 4, such as a traditional relational database, a file system, a non-relational database, etc.) or a medical cloud database (i.e., the cloud service in fig. 4):
specifically, data to be kept is used as input, summary information and data index information of the data are generated and stored in an intelligent contract of a block chain;
the data index information may specifically be link address information of the valid questionnaire data, and the summary information may specifically be a code value of the valid questionnaire data (which is a unique summary value, such as a Hash value, and when the content of the valid questionnaire data changes, the summary value changes correspondingly);
it can also be understood that the data index information stored on the block chain is used for recording the specific position of the effective questionnaire data in the traditional database or the medical cloud database; specifically, the abstract information and the data index information of the effective questionnaire data can be stored in a block (the data in a block chain is stored in blocks, each block comprises a block head and a block body, the block head is used for linking, and the block body is used for storing the data);
the questionnaire data of hospital a and the questionnaire data of hospital B in fig. 4 are only examples of valid questionnaire data, and are not limited thereto.
