Detailed Description

The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.

Example 1

Fig. 1 is a flowchart of a credit data processing method based on a blockchain according to an embodiment of the present invention, where the present embodiment is applicable to the case of processing credit data based on a blockchain technique. The applicable blockchain may be a public chain or a federated chain. The whole set of credit data processing method based on the block chain is usually carried out by the block chain node, a service server for processing credit data and a data source device for uploading data for signal. The service server may be a dedicated server for providing enterprise credit service, and may interact with the blockchain node, for example, may be a common node in the blockchain that stores transaction data, may be a lightweight node that does not store transaction data, or may be a server that hops to a blockchain technology based on a client interface or a web page, or the like. The scheme of the embodiment of the invention is applied to the business server, the method can be executed by a credit data processing device or equipment based on a block chain, and the device can be realized in a hardware and/or software mode and can be integrated in a computing equipment carrying the business server. Referring to fig. 1, the method specifically comprises the following steps:

s110, 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.

In this embodiment, the data source device refers to a device such as a server or a terminal that can be used to upload source data for signaling to a blockchain, where the device is a device that generates original credit data and has a strong public trust; the node can be a common node for storing transaction data in a blockchain or a lightweight node for not storing the transaction data; the blockchain node may not be present, but may interact with the blockchain through a data interaction platform (e.g., a client interface or web page, etc.) provided by the blockchain node, such as may send data to the blockchain. By way of example, the data source devices may include government agencies, third party agencies, and other highly trusted devices; government agencies may include, but are not limited to, national committee for improvement, business bureau, highest national court, tax bureau, and the like; third party institutions may include, but are not limited to, banks (e.g., china Bank, etc.), insurance companies, and the like.

The credit source data is credit original data of any enterprise or person generated by the data source device, and can include at least one of the following: administrative penalty data, legal referees documents, business management data, tax data, bank transfer data, credit data, and insurance claim data.

Specifically, the service server can determine whether the data source device stores credit source data in the blockchain by monitoring the behavior of the data source device or transaction requests in the blockchain, and the like, and can also determine that the data source device stores the credit source data in the blockchain by receiving a notification of the data source device; queries may also be made from the blockchain to determine that the data source device is storing credit source data into the blockchain, and so on. For example, determining that the data source device stores credit source data into the blockchain may include at least one of:

A. monitoring the behavior of the data source device for uploading credit source data to the blockchain to determine that the data source device stores the credit source data into the blockchain;

alternatively, the data source device may upload the source data for the signal to the blockchain through a specific frequency or communication channel or the like. Thus, the traffic server may monitor the frequency or communication channel in real time to determine if the data source device has the act of uploading credit source data to the blockchain. For example, when the service server monitors that the communication channel where the data source device and the blockchain interact has information flow, and the direction of the information flow is that the data source device flows to the blockchain, it is determined that the data source device has a behavior of uploading credit source data to the blockchain at the moment, and then it can be determined that the data source device stores the credit source data in the blockchain.

B. Monitoring 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 a blockchain network; a declaration identification may be included for informing the blockchain network that credit source data is included in the transaction request; alternatively, the declaration identification may be a source address of the credit source data (address of the data source device), an identification 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 monitor all or credit source data storage transaction requests in the blockchain network, and if the transaction requests store an active address or an identifier of the credit source data, the transaction requests are considered to carry the credit source data, so as to determine that the data source device stores the credit source data into the blockchain.

C. Transaction data query is conducted on 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 can be traversed from the current generation block of the local block chain, and if the current generation block is queried to store credit source data, the current generation block can be determined to store the credit source data.

If the service server is not the current block generation node, is a lightweight node or is not a blockchain 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 the blockchain address are fed back to the service server; the service server receives the credit source data and the blockchain address fed back by the current block generating node, and can determine that the credit source data is stored in the current generating block.

D. And receiving a credit source data uplink notification sent by the data source device to determine that the data source device stores the credit source data into the blockchain.

In this embodiment, the credit source data uplink notification may be a notification sent to the service server after the data source device sends the credit source data as a transaction request to the blockchain network. 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 blockchain address refers to a storage address of credit source data in the blockchain, and may include a block identifier and an offset.

Specifically, if the service server determines that the data source device stores credit source data into the blockchain, the credit source data and a blockchain address for storing the credit source data can be obtained from the blockchain; because the data source equipment sends the credit source data 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 equipment or the service server when the transaction request is stored in the uplink; thus, the service server may obtain credit source data and blockchain addresses directly from the data source device or obtain credit source data from the data source device and blockchain addresses from the blockchain.

S120, processing the credit source data according to a set processing mode to obtain a credit processing result, wherein rule data of the set processing mode is stored in a blockchain.

In this embodiment, the setting processing mode refers to a preset mode of processing credit source data, and may include at least one of setting a cleaning mode, setting an aggregation mode, setting a credit evaluation model, and the like. 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 aggregation result, or the like. Alternatively, different setting processing modes may correspond to different credit processing results.

In order to improve the credibility of the credit processing result, the rule data of the setting processing mode can be stored in the blockchain, so that the rule data of the setting processing mode is transparent, any enterprise or individual can acquire the rule data of the setting processing mode from the blockchain at any time, and further, the rule data of the setting processing mode is adopted to verify whether the credit processing result of the business server or the blockchain node is correct.

For example, rule data for setting the processing mode may be updated according to actual situations. If the rule data of the set processing mode is updated, the updated rule data of the set processing mode may be sent to the blockchain network, so that the blockchain network stores the rule data of the new set processing mode. Therefore, if the blockchain network receives a rule data acquisition request or a verification request sent by any enterprise or person through a client interface or a web page, the blockchain network can traverse forward from the current block, and feed back the rule data of the first acquired setting processing mode, so as to ensure that the rule data of the setting processing mode is up to date.

Specifically, the service server may process the acquired credit source data according to one or more of the set processing modes, so as to obtain a credit processing result; and a credit data processing transaction request can be sent to the blockchain network to request the blockchain link point to process the credit source data according to the set processing mode, and feedback the credit processing result and the like. Optionally, different processing manners may correspond to different scheduling policies, and the following embodiments will describe in detail a scheme for processing credit source data according to a set processing manner.

And S130, carrying out association display on the credit processing result, the set processing mode and the blockchain address of the credit source data.

Specifically, after obtaining the credit processing result corresponding to the credit source data, the service server can establish the association relationship among the blockchain address of the credit source data, the credit processing result and the used setting 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 credit processing result of this time, and the relevant information is perfected according to the credit processing result, and the benign development of the enterprise is finally realized.

According to the technical scheme provided by the embodiment of the invention, after the service server determines that the data source equipment stores the credit source data into the blockchain, the service server acquires the credit source data and the blockchain address from the data source equipment or the blockchain; and then, the acquired credit source data is processed by adopting a setting processing mode that the rule data of the setting processing mode is stored in the blockchain, so that a credit processing result is acquired, and the credit processing result, the used setting processing mode and the blockchain address of the credit source data are displayed in a correlated way. Compared with the existing credit data processing platform, the credit source data is stored in the blockchain, 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 blockchain, 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 blockchain at any time, the credit processing result of the credit source data is verified, and the acceptance of the credit processing result is improved.

In this embodiment, the set cleansing processing mode is one of the set processing modes, and is used for processing the format, the content, and the like of the credit source data so as to remove or change the content or the format which does not meet the regulations, and is a standard processing. Optionally, setting the cleaning processing mode may include integrating a planning processing rule, where the integrating a planning processing rule may include a data content processing rule, a format processing rule, and the like.

Specifically, after the service server obtains the credit source data, the format of the credit source data can be processed according to the format processing rule in the planning processing rule, for example, the credit source data adopts Song style, and the regular script is appointed in the format processing rule, so that the font of the credit source data can be changed into regular script and the like, and further, the situation of obvious format errors is avoided; processing the data content of the credit source data subjected to format processing according to the content processing rules in the compliance processing rules so as to remove or change the data content which does not meet the regulations, and finally obtaining the credit processing result after cleaning; the cleaned credit processing results may then be sent to the data source device or blockchain in the cleaning mode used.

Alternatively, the cleaned credit processing results may be presented in the form of scores or the like, so that the data source device normalizes the credit source data format or the like.

And S230, carrying out association display on the credit processing result, the set processing mode and the blockchain address of the credit source data.

Illustratively, processing the credit source data according to a set processing manner to obtain a credit processing result may further include at least one of:

A. and carrying out aggregation processing on the credit source data according to a set aggregation processing mode to obtain an aggregation result taking a set target as a dimension, 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 data type, enterprise, time and set result content.

In this embodiment, the format unification rule is to set the format of the credit source data to a unified format, for example, the format may be set as "regular script is small four, two ends are aligned, and a single line space"; it may also be uniformly set to "binary form" or the like. The content unification rule is a rule for extracting, from credit source data, credit source data of the same content having the same meaning, purpose, function, or the like, as credit source data required for setting an aggregation processing method. The association aggregation rule refers to a rule for aggregation between credit source data, such as aggregation in data type, time or enterprise.

Specifically, format and content unification processing can be performed on credit source data according to format unification rules and content unification rules in a set aggregation processing mode, and then association aggregation is performed on the processed credit source data according to association aggregation rules in the set aggregation processing mode, for example, aggregation is performed according to data types, so that an aggregation result taking the data types as dimensions is obtained.

Specifically, a credit rating model can be set, and credit source data required by the setting of the rating model can be rated, so that a rating result can be obtained. Alternatively, the rating results may be presented in a hierarchical or fractional format so that the business or individual can intuitively obtain their own credit scores.

It should be noted that, for the processing of the credit source data, any one or more of the three setting processing modes given above may be adopted. The three setting processing modes have no absolute association relation and no sequence division, and can be flexibly selected according to actual requirements. If the credit rating model is used, the cleaning treatment is firstly carried out by adopting a set cleaning treatment mode, then the aggregation treatment is carried out on the cleaned credit treatment results according to a set aggregation treatment mode, and finally the aggregation results are rated by adopting a set credit rating model to carry out rating treatment.
