Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved more apparent, the following detailed description will be made with reference to the accompanying drawings and specific embodiments.
The invention provides a data processing method, which aims at the problem that questionnaire data in the prior art lacks public confidence, and as shown in figure 1, comprises the following steps:
step 11: acquiring questionnaire data to be processed;
step 12: and calling an intelligent contract on the blockchain to clean the questionnaire data to be processed.
The data processing method provided by the embodiment of the invention is characterized by acquiring questionnaire data to be processed; calling an intelligent contract on a block chain to clean the questionnaire data to be processed; the method can ensure the non-tamper property, the traceability and the disclosure transparency of the data processing process, greatly improve the public trust of the questionnaire data and well solve the problem of lack of public trust of the questionnaire data in the prior art.
The calling the intelligent contract on the blockchain to clean the questionnaire data to be processed comprises the following steps: and calling the intelligent contract on the blockchain 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 calling the intelligent contract on the blockchain to clean the questionnaire data to be processed includes: invoking an intelligent contract on a blockchain to authenticate the questionnaire data to be processed; if the authentication is passed, executing a questionnaire recording operation on the questionnaire data to be processed, and newly adding a transaction record message in a blockchain; 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 invoking the intelligent contract on the blockchain to authenticate the questionnaire data to be processed includes: invoking an intelligent contract on a blockchain, 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 accords with a preset reverse verification condition; if yes, determining that the authentication is passed; if not, determining that the authentication is not passed.
The method can also be as follows: the invoking of the intelligent contract on the blockchain authenticates the questionnaire data to be processed, including: invoking an intelligent contract on a blockchain, and judging whether an identity of an operator corresponding to the questionnaire data to be processed is unique, whether the geographic position of the operator is matched with a preset geographic position, and whether the state of the operator when filling in the questionnaire is matched with the preset state; if yes, determining that the authentication is passed; if not, determining that the authentication is not passed.
More specifically, invoking an intelligent contract on a blockchain to determine whether the content of the questionnaire data to be processed meets a preset reverse verification condition, including: acquiring whether filling contents of the questionnaire data to be processed aiming at preset forward questions are opposite to filling contents of corresponding preset reverse questions; if yes, determining that the content of the questionnaire data to be processed accords with a preset reverse verification condition; if not, determining that the content of the questionnaire data to be processed does not accord with a preset reverse verification condition.
Correspondingly, the above-mentioned intelligent contract on the calling blockchain, the judging whether the state of the operator corresponding to the questionnaire data to be processed when filling in the questionnaire matches with the preset state may include: acquiring whether the filling content of the operator aiming at the preset forward problem is opposite to the filling content of the corresponding preset reverse problem; if yes, determining that the state of the operator when filling in the questionnaire is matched with a preset state; 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 carefully answers questions (carefully fills out questionnaires).
Further, before acquiring the questionnaire data to be processed, the method further comprises: constructing the intelligent contract; the smart contract is deployed on the blockchain.
Still further, deploying the smart contract on the blockchain further includes: an account address and a transaction hash value of the smart contract are generated.
Wherein after calling the intelligent contract on the blockchain and cleaning the questionnaire data to be processed, the method further comprises the following steps: obtaining effective questionnaire data according to the questionnaire data to be processed after the cleaning treatment; and storing the valid questionnaire data into a preset database.
Further, in order to fully uplink 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 on a blockchain.
The data processing method provided by the embodiment of the invention is further described below.
Aiming at the technical problems, a scheme capable of enabling multiple parties to trust is needed to collect questionnaires, and data sources and other information are stored in a public and safe manner; considering that the blockchain technology is used for a bitcoin system at the earliest, the system is a distributed account book, has non-falsifiability and is suitable for storing transaction records; the intelligent contract can be seen as a section of program code stored and running on the blockchain, is an activity rule and an associated contract commonly known by related parties participating in an activity, and shows the rule and the contract in a code manner and puts the rule and the contract in the blockchain for execution; moreover, once agreed upon and placed on the blockchain, the smart contract is also transparent to all active participants and is not modifiable. The smart contract execution process, status, input and output data will also be recorded in the blockchain and be unalterable, transparent to all active participants.
Therefore, the traceability and the tamper-resistant characteristic of the blockchain are in line with the requirements, and the intelligent contract technology also provides a convenient realization way for collecting questionnaires. However, implementing questionnaire collection with blockchain has the following drawbacks:
1. satisfaction questionnaires are large in quantity in the whole country, and a large number of invalid questionnaires exist, such as repeated questionnaires and faking questionnaires, and the invalid questionnaires have great influence on the accuracy of data analysis and conclusion.
2. Due to the characteristics of the block chain technology, the efficiency of the whole network synchronous data in the p2p network (peer-to-peer network) is low, and the method is not suitable for storing larger data. Therefore, massive questionnaire data cannot be fully uploaded.
In view of the above technical problems and these drawbacks, an embodiment of the present invention provides a data processing method, which mainly relates to the following two aspects:
1. for defects where invalid questionnaires exist: the embodiment of the invention adopts an intelligent contract technology, is deployed at each node in the blockchain, cleans invalid questionnaire data, and realizes tamper resistance of the valid questionnaire data.
2. Aiming at the defect that massive questionnaire data is too large to be totally uplink: in the embodiment of the invention, an address mapping mode is adopted, original questionnaire data is stored in a preset database (such as a traditional database), and database address mapping (data index information) and summary information are stored on a blockchain.
The method comprises the following steps:
1. questionnaire data processing using smart contracts
1. Constructing an intelligent contract parent (the intelligent contract comprises functions of questionnaire cleaning, questionnaire inquiring, questionnaire authorizing, questionnaire storing and the like), deploying the intelligent contract parent on a blockchain, and automatically generating and returning an account address and a transaction Hash (Hash) value of the intelligent contract parent by the blockchain during deployment; the deployed intelligent contract parent needs to be recorded into the blockchain after being acknowledged by the blockchain, and is transparent and unchangeable. Specifically, the "get consensus via blockchain validation" may be that nodes on the blockchain will validate the normative of the intelligently contracted grammar, the invoker's invocation permissions, and so on.
The intelligent contract parent prescribes a questionnaire cleaning execution process and a questionnaire cleaning mode method, and defines a data structure related in the questionnaire cleaning mode method execution process.
The "deployment of smart contract parent on blockchain" may be specifically: the method comprises the steps that a blockchain client or an application program interface API on a local server is connected to a preset node (a specific node) on a P2P network where a blockchain is located, and node authentication is passed; calling an intelligent contract deployment script on the node, deploying the intelligent contract to the node, and pushing the intelligent contract to other nearby nodes by the node; each node on the blockchain respectively verifies and locally deploys contracts and propagates the contracts to other nodes nearby each other, and finally, full-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 implementation of the intelligent contract in the embodiment of the invention can be shown in fig. 3 (an operator takes a patient in a hospital as an example), and after the patient logs in the questionnaire system, the questionnaire is submitted; then the questionnaire system calls a login authentication method in the intelligent contract on the blockchain to authenticate the identity and authority of the logged patient:
(1) Judging whether the ID filled in by the patient is unique when the questionnaire is initiated; if the geographic position of the patient is matched (namely (2)) if the geographic position of the patient is unique, if the geographic position of the patient is not unique, the process is ended;
(2) Judging whether the geographic position of the patient is consistent with the geographic position of the hospital when the questionnaire is initiated; if the answer is met, entering reverse question verification (namely entering (3), specifically, asking questions in different description modes for individual questions in a questionnaire, such as the same question, if the answer selected by a patient is 'yes' when the first time appears, and if the answer of the patient appears in another mode (specifically, the opposite questionnaire mode to the first time), the answer of the patient should theoretically be 'no', if the answer of the patient is not the case, namely, the answers of the questions of the patient in different modes for the same question are not uniform, the patient questionnaire does not pass in the reverse question verification link, namely, the patient questionnaire does not meet the preset reverse verification condition; if not, ending the flow;
(3) Judging whether the patient gives serious questions according to the reverse questions preset by the questionnaire, if so, executing the recorded questionnaire (namely entering (4)); if not, ending the flow;
(4) Executing a record questionnaire, and adding a blockchain transaction questionnaire record; specifically, a transaction record may be newly added to the blockchain transaction list.
2. Address mapping and digest information uplink
1. As in fig. 4, valid questionnaire data is saved in a traditional database (i.e., the de-chained database in fig. 4, such as a traditional relational database, file system, non-relational database, etc.) or a medical cloud database (i.e., the cloud service in fig. 4):
specifically, data to be maintained is taken as input, summary information and data index information of the data are generated and stored in an intelligent contract of a blockchain;
the data index information may be specifically link address information of the valid questionnaire data, and the summary information may be specifically 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 correspondingly changes);
it can also be understood that storing data index information on the blockchain is used to record the specific location of valid questionnaire data in a traditional database or a medical cloud database; specifically, the summary information and the data index information of the valid questionnaire data can be stored in a block (the data in the blockchain is stored in blocks; each block comprises a block head and a block body, the block head is responsible for linking, and the block body is responsible for storing the data);
