Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for processing credit data based on a block chain according to an embodiment of the present invention, which is applicable to a case of processing credit data based on a block chain technique. The applicable blockchains may be public or alliance chains. The whole set of block chain-based credit data processing method is usually executed by the cooperation of block chain nodes, a service server for processing credit data and data source equipment for uploading credit data. The service server may be a dedicated server providing an enterprise credit service, and may interact with the blockchain nodes, for example, the service server may be a common node in the blockchain that stores the transaction data, or a lightweight node that does not store the transaction data, or a server that jumps to a server carrying a blockchain technique based on a client interface or a web page. The scheme of the embodiment of the invention is applied to the service server, and the method can be executed by a credit data processing device or equipment based on the block chain, the device can be realized in a hardware and/or software mode, and can be integrated in computing equipment bearing the service server. Referring to fig. 1, the method specifically includes the following steps:
and S110, if the data source device is determined to store the credit source data into the block chain, acquiring the credit source data and the block chain address from the data source device or the block chain.
In this embodiment, the data source device refers to a device such as a server or a terminal that can be used to upload credit source data to a block chain, and the device generates original credit data and has a strong public trust; the node can be a common node for storing the transaction data in the block chain or a lightweight node for not storing the transaction data; the blockchain node may also be not a blockchain node, but may interact with the blockchain through a data interaction platform (such as a client interface or a web page) provided by the blockchain node, such as data may be sent to the blockchain. For example, the data source device may include government agencies, third party agencies, and other devices with high public trust; government agencies may include, but are not limited to, the national institute of improvement, the institute of industry and commerce, the highest people's court, the central office of taxation, and the like; the third party organization may include, but is not limited to, banks (e.g., china banks, etc.) and insurance companies, etc.
The credit source data refers to the credit original data of any enterprise or person generated by the data source device, and may include at least one of the following: administrative penalty data, legal referee documents, business administration data, tax data, bank transfer data, credit data, and insurance claim data.
Specifically, the service server may determine whether the data source device stores the credit source data in the blockchain by monitoring a behavior of the data source device or a transaction request in the blockchain, and may also determine that the data source device stores the credit source data in the blockchain by receiving a notification of the data source device; a query may also be made from the blockchain to determine that the data source device stores credit source data into the blockchain, and so on. For example, determining that the data source device stores the credit source data in the block chain may include at least one of:
A. monitoring the behavior of uploading credit source data to the block chain by the data source equipment to determine that the credit source data are stored into the block chain by the data source equipment;
optionally, the data source device may upload the credit source data to the blockchain through a specific frequency or communication channel, etc. Thus, the traffic server may listen to the frequency or communication channel in real-time to determine whether the data source device has the behavior to upload the credit source data to the blockchain. For example, when the service server monitors that an information stream flows through a communication channel where the data source device interacts with the block chain, and the direction of the information stream is that the data source device flows to the block chain, it is determined that the data source device has a behavior of uploading credit source data to the block chain at this time, and it may be further determined that the data source device stores the credit source data into the block chain.
B. Listening for credit source data storage transaction requests in the blockchain network to determine that the data source device stores credit source data into the blockchain;
in this embodiment, the credit source data storage transaction request refers to a transaction request for storing credit source data to the blockchain network; a declaration identification may be included for informing the blockchain network that the transaction request includes credit source data; alternatively, the declaration identifier may be a source address of the credit source data (address of the data source device), an identifier of the credit source data, or the like. The identification of the credit source data may be obtained by hash signing of the credit source data by the data source device.
Specifically, the service server may listen to all or credit source data storage transaction requests in the blockchain network, and if a source address or an identifier of credit source data and the like are stored in the transaction request, the transaction request is considered to carry the credit source data, and it is determined that the data source device stores the credit source data in the blockchain.
C. Performing transaction data query aiming at the current generation block to determine that credit source data storage exists in the current generation block;
specifically, if the service server is the current block generation node, the transaction data may be traversed from the current generation block of the local block chain, and if it is found that credit source data is stored in the current generation block, it may be determined that credit source data is stored in the current generation block.
If the service server is not the current block generation node, is a lightweight node or is not a block link node, a transaction data query request can be sent to the current block generation node to request the current block generation node to traverse the current generation block for transaction data query, and if the current generation block is queried to store credit source data, the credit source data and a block link address are fed back to the service server; the service server receives the credit source data and the block chain address fed back by the current block generation node, and can determine that the credit source data is stored in the current block.
D. And receiving a credit source data uplink notification sent by the data source equipment to determine that the data source equipment stores the credit source data into the block chain.
In this embodiment, the credit source data uplink notification may be a notification sent to the service server by the data source device after sending the credit source data to the blockchain network as the transaction request. Specifically, when the service server receives the credit source data uplink notification sent by the data source device, it may be determined that the data source device stores the credit source data in the blockchain.
In this embodiment, the block chain address refers to a storage address of the credit source data in the block chain, and may include a block identifier and an offset.
Specifically, if the service server determines that the data source device stores the credit source data into the block chain, the credit source data and the block chain address for storing the credit source data may be obtained from the block chain; after the data source device sends the credit source data serving as the transaction request to the blockchain network for storage, the blockchain network can feed back the blockchain address of the transaction data corresponding to the transaction request to the data source device or the service server when the blockchain network stores the transaction request in an uplink; therefore, the service server can directly acquire the credit source data and the blockchain address from the data source device, or acquire the credit source data from the data source device and acquire the blockchain address from the blockchain.
And S120, processing the credit source data according to a set processing mode to obtain a credit processing result, wherein the regular data of the set processing mode is stored in the block chain.
In this embodiment, the setting processing method is a preset method for processing the credit source data, and may include at least one of setting a cleaning method, setting an aggregation method, and setting a credit evaluation model. The rule data for setting the processing mode is the processing rule or specification for setting the processing mode. The credit processing result may be a rating result, an aggregate result, or the like. Optionally, different setting processing manners may correspond to different credit processing results.
In order to improve the credibility of the credit processing result, the rule data of the set processing mode can be stored in the block chain, the rule data of the set processing mode is made transparent, so that any enterprise or individual can acquire the rule data of the set processing mode from the block chain at any time, and further the rule data of the set processing mode is adopted to verify whether the credit processing result of the business server or the block chain link point is correct.
For example, the rule data for setting the processing mode may be updated according to actual situations. If the rule data of the set processing method is updated, the updated rule data of the set processing method may be transmitted to the blockchain network so that the blockchain network stores the new rule data of the set processing method. Therefore, if the blockchain network receives a rule data acquisition request or a verification request and the like sent by any enterprise or person through a client interface or a webpage and the like, the rule data of the set processing mode acquired for the first time can be fed back from the current block, so as to ensure that the rule data of the set processing mode is the latest.
Specifically, the service server may process the acquired credit source data according to one or more of the set processing manners, and further obtain a credit processing result; the credit data processing transaction request can be sent to the blockchain network, so that the request blockchain nodes process the credit source data according to a set processing mode, and feed back credit processing results and the like. Optionally, different processing manners may correspond to different scheduling policies, and a scheme for processing the credit source data according to the set processing manner will be described in detail in the subsequent embodiments.
S130, the credit processing result, the used setting processing mode and the block chain address of the credit source data are related and displayed.
Specifically, after the business server obtains the credit processing result corresponding to the credit source data, the business server can establish the association relationship among the block chain address of the credit source data, the credit processing result and the used set processing mode, and display the association relationship to the enterprise or the individual in a webpage or other forms so that the enterprise or the individual can verify or inquire the current credit processing result, and improve the relevant information according to the credit processing result, thereby finally realizing the benign development of the enterprise.
According to the technical scheme provided by the embodiment of the invention, after determining that the credit source data is stored in the block chain by the data source equipment, the service server acquires the credit source data and the block chain address from the data source equipment or the block chain; and then, the acquired credit source data is processed by adopting a setting processing mode in which the rule data of the setting processing mode is stored in the block chain, so that a credit processing result is acquired, and the credit processing result, the used setting processing mode and the block chain address of the credit source data are displayed in an associated manner. Compared with the existing credit data processing platform, the scheme stores the credit source data in the block chain, so that the reliability of the credit source data source is ensured; meanwhile, the rule data of the set processing mode for processing the credit source data is stored in the block chain, so that the rule data of the set processing mode is transparent, any enterprise or individual can acquire the rule data of the set processing mode from the block chain at any time, the credit processing result of the credit source data is verified, and the recognition degree of the credit processing result is improved.
Example two
Fig. 2 is a flowchart of a block chain-based credit data processing method according to a second embodiment of the present invention, and the second embodiment of the present invention further explains a credit processing result obtained by processing credit source data according to a set processing manner on the basis of the first embodiment. Referring to fig. 2, the method specifically includes the following steps:
s210, if the data source device is determined to store the credit source data into the blockchain, the credit source data and the blockchain address are acquired from the data source device or the blockchain.
And S220, cleaning the credit source data according to a set cleaning treatment mode to obtain a cleaned credit treatment result, wherein the set cleaning treatment mode comprises a compliance treatment rule.
In this embodiment, the setting of the cleaning processing method is one of setting processing methods, and is a standard processing method for performing processing such as format and content on the credit source data to remove or modify the content or format that does not meet the specification. Optionally, the set cleaning processing manner may include a co-planning processing rule, and the co-planning processing rule may include a data content processing rule, a format processing rule, and the like.
Specifically, after the service server acquires the credit source data, the format of the credit source data may be processed according to the format processing rule in the co-planning processing rule, for example, the credit source data adopts sons, and a regular script is specified in the format processing rule, so that the font of the credit source data may be changed into a regular script, and the like, thereby avoiding the occurrence of an obvious format error; then, according to the content processing rule in the compliance processing rule, processing the data content of the credit source data after format processing so as to remove or change the data content which does not accord with the regulation, and finally obtaining the cleaned credit processing result; the scrubbed credit processing results and the used scrubbing mode may then be sent to the data source device or blockchain.
Optionally, the cleaned credit processing result may be presented in the form of score, etc. so that the data source device standardizes the credit source data format, etc.
S230, the credit processing result, the used setting processing method and the block chain address of the credit source data are displayed in association.
According to the technical scheme provided by the embodiment of the invention, after the business server acquires the credit source data, the credit source data can be cleaned according to a set cleaning treatment mode so as to remove or change data contents or data formats which do not accord with the regulation, and further avoid the condition of obvious formats or wrong contents; and the cleaned credit processing result, the block chain address of the credit source data and the used cleaning mode are displayed in a correlated manner, so that the data source equipment standardizes the format of the credit source data and the like.
For example, the processing the credit source data according to the set processing manner to obtain the credit processing result may further include at least one of the following:
A. and performing aggregation processing on the credit source data according to a set aggregation processing mode to obtain an aggregation result with a set target as a dimensionality, wherein the set aggregation processing mode comprises a format unification rule, a content unification rule and an association aggregation rule, and the set target is at least one of a data type, an enterprise, time and a set result content.
In this embodiment, the format unification rule is to set the format of the credit source data to be a unified format, for example, the unified format may be set to "regular script is four in size, two ends are aligned, and single-row-spacing"; but also can be uniformly set to be in a binary form, and the like. The content unification rule is a rule for extracting credit source data having the same meaning, the same purpose, the same function, or the like from the credit source data as credit source data necessary for setting the aggregation processing method. The association aggregation rule refers to a rule for aggregating credit source data, and may be aggregated according to data type, time, or enterprise.
Specifically, format unification processing and content unification processing may be performed on the credit source data according to a format unification rule and a content unification rule in the set aggregation processing mode, and then association aggregation is performed on the processed credit source data according to an association aggregation rule in the set aggregation processing mode, for example, aggregation is performed according to a data type, so that an aggregation result with the data type as a dimension is obtained.
B. And carrying out rating processing on the credit source data according to a set credit rating model so as to obtain a rating result.
In this embodiment, setting the credit rating model refers to a preset model for evaluating credit. Alternatively, the credit rating model may be set differently, with different functions or purposes.
Specifically, a set credit rating model may be adopted to perform rating processing on credit source data required by the set credit rating model, and further obtain a rating result. Alternatively, the rating results may be presented in the form of a rating or score, so that the business or individual may visually obtain his or her credit score.
It should be noted that, for the processing of the credit source data, any one or more of the three setting processing manners given above may be adopted. The three setting and processing modes have no absolute incidence relation and precedence, and can be flexibly selected according to actual requirements. For example, a set cleaning processing mode is adopted for cleaning, then the cleaned credit processing results are aggregated according to a set aggregation processing mode, and finally a set credit rating model is adopted for rating the aggregated results.
EXAMPLE III

Optionally, the rule storage transaction request may include a rule data identifier, where the rule data identifier may be obtained by the service server performing hash signature on the rule data in the set processing manner.
Specifically, the service server may carry rule data of a set processing mode in a rule storage transaction request, and initiate the rule data to the blockchain network; after receiving the regular storage transaction request, the block chain node determines that the regular storage transaction request comprises the regular data of the set processing mode through identifying the regular data identifier, and stores the regular data of the set processing mode into the block chain; the blockchain node may then feed back the blockchain address of the rule data to the service server for subsequent use in querying or validation, etc.
It should be noted that step S320 may be executed before or after the credit source data is processed according to the setting processing manner to obtain the credit processing result (steps S330 and S340 in the present embodiment). Optionally, if the processing is executed after S330 and S340, the credit processing result and the rule data of the set processing mode may be stored in the same block in an associated manner, that is, only one block chain address is needed to obtain the rule data of the set processing mode and the credit processing result at the same time.
S330, a credit data processing transaction request is sent to the blockchain network, and credit source data required by a set processing mode is processed by the request blockchain node according to the rule data of the set processing mode specified in the credit data processing transaction request to obtain a credit processing result and is stored in the blockchain.
