Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The service data processing method based on the block chain can be applied to the application environment shown in fig. 1. Wherein the ping terminal 102 and the blockchain 106 communicate with the server 104 over a network. The server 104 may query whether new service data exists on a block chain node corresponding to each service participant, and if yes, obtain an intelligent contract corresponding to the block chain node, obtain a data identifier of the new service data, query the intelligent contract according to the data identifier to obtain a corresponding data rule, and audit the new service data through the data rule to obtain an audit result; and when judging that the newly added service data is abnormal according to the auditing result, generating early warning information according to the newly added service data, and sending the generated early warning information to the checking terminal. Therefore, when the customs needs to be audited, the data of each party is obtained instead of only one participant providing the data, the source of the data is improved, the diversity and the safety of the data are guaranteed, and in addition, the auditing is carried out through the intelligent contract on the block chain, so that the stability of the data can be guaranteed. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In an embodiment, as shown in fig. 2, a method for processing service data based on a block chain is provided, which is described by taking the method as an example applied to the server in fig. 1, and includes the following steps:
s202: and inquiring whether the block chain node corresponding to each service participant has new service data.
Specifically, each participant (including roles of warehousing enterprises, processing enterprises, logistics companies and the like) of the business in the special supervision area is added into the supply chain financing system based on the block chain, the system construction party deploys block chain nodes for each participant, and each participant completes the real-name authentication of the enterprise and acquires the electronic signature.
The service participants upload the service data generated in the special supervision area to the bonded area management system based on the block chain, including various static service data and dynamic service data, such as: static data: BOM, bin location information, etc.; dynamic data: warehousing bills, work orders, material picking orders, ex-warehouse bills, shipping orders and the like. And the information is uploaded in a mode of supporting manual input and system docking. And all the uploaded service data are provided with the electronic signatures of the respective uploaders.
Optionally, if the enterprise does not want to disclose its own business data, each participant can encrypt the data, link the ciphertext data to other nodes and synchronize the ciphertext data to other nodes, and directionally grant the decryption key to the customs in the supervision position. And after the customs obtains the data of the node, the customs can decrypt the data according to the directional authorization key to obtain the original service data, and the original service data is compared with the data on the declaration form to complete the verification of the declaration form.
Specifically, the block link node may store newly added service data uploaded by each participant, and add a newly added identifier during storage, so that when the server queries the newly added identifier, it may be determined that newly added data exists on the block link node.
S204: and when newly added service data exists on the block chain node corresponding to a certain service participant, acquiring an intelligent contract corresponding to the block chain node.
Specifically, the inspection terminal, for example, the customs terminal may compile rules into an intelligent contract based on the supervised rules and issue the intelligent contract onto the block chain, and the customs terminal first compiles codes of the intelligent contract, including dividing the intelligent contract into a single-party data rule and a cross data rule according to types, and setting a data identifier for data to be filled in each data rule to determine the type of corresponding data, and finally stores the compiled data.
When new service data exists on the server, the server can read the data with the new identifier from the block chain. After reading the corresponding new data, the server may further determine a block link point corresponding to the new data, and then acquire an intelligent contract corresponding to the block link point, for example, if the block link point corresponds to a logistics party, the intelligent contract corresponding to the logistics party needs to be acquired. And if the payment party is the payer, acquiring an intelligent contract corresponding to the payment and the like.
S206: and acquiring a data identifier of the newly added service data, and inquiring the intelligent contract according to the data identifier to obtain a corresponding data rule.
In particular, the data identification refers to identification of a data type, such as time, BOM, and the like. After the server obtains the intelligent contract, it needs to determine which data rules in the intelligent contract to audit the newly added service data. Specifically, the server may obtain a data identifier of newly added service data, and then match the data identifier with a data rule in the intelligent contract, so as to obtain a data rule meeting requirements.
S208: and auditing the newly added service data through the data rule to obtain an auditing result.
Specifically, after the server obtains the data rule, whether the newly added service data meets the data rule is judged, if yes, it is indicated that the newly added service data has no problem, otherwise, the newly added service data has a problem. Optionally, there may be multiple data rules acquired by the server, so that it is necessary to determine whether the newly added service data satisfies all the data rules, and if there is an unsatisfied data rule, directly outputting an audit result of the newly added service data that has a problem, and recording the unsatisfied data rule.
S210: and when judging that the newly added service data is abnormal according to the auditing result, generating early warning information according to the newly added service data, and sending the generated early warning information to the checking terminal.
Specifically, when determining that the newly added service data has a problem, the server generates early warning information according to the newly added service data, for example, associates the newly added service data with an unsatisfied data rule to obtain early warning information, and sends the early warning information to the inspection terminal.
According to the block chain-based business data processing method, data are uploaded to the block chain by each party, so that when customs needs to be audited, the data of each party is obtained instead of only one participant providing data, the source of the data is improved, the diversity and the safety of the data are guaranteed, and in addition, the auditing is carried out through an intelligent contract on the block chain, so that the stability of the data can be guaranteed.
In one embodiment, please refer to fig. 3, fig. 3 is a flowchart of step S208 in the embodiment shown in fig. 2, in this embodiment, the step S208, that is, auditing the newly added service data through the data rule to obtain an audit result, includes:
s302: and grouping the data rules to obtain unilateral data rules audited by a unilateral and cross audited multiparty data rules.
Specifically, when the data rule in each intelligent contract is written, an identifier, that is, a single-party data rule or a cross data rule, can be determined, and after the server acquires the data rule for auditing the newly added service data, the server performs grouping processing on the data rule according to the identifier.
S304: the new business data is audited by calling a single-party data rule through the first thread to obtain a first audit result; and calling a cross auditing rule through the second thread to audit the newly added service data to obtain a second auditing result.
S306: and when the first audit result or the second audit result is judged to be abnormal, generating an audit result representing that the newly added service data is abnormal.
Specifically, after grouping is completed, the server sets two threads to process the newly added service data respectively so as to improve the processing efficiency, that is, the first thread calls a single-party data rule to audit the newly added service data to obtain a first audit result, and the second thread calls a cross audit rule to audit the newly added service data to obtain a second audit result, so that the first audit result and the second audit result are combined to obtain a final audit result.
For example, a single data rule may include: and the goods are not reported 14 days after entering the district: which batch of goods of which enterprise has not been reported after entering the district on which day. For example, after the enterprise operates the ex-warehouse service, the inventory quantity is smaller than 0. The cross-data rules may include: whether the transportation quantity of the transportation company is equal to the ex-warehouse quantity of the warehousing enterprise. The server may execute the unilateral data rule by one thread and the cross data rule by another thread.
In the embodiment, the data rules are distinguished according to the unilateral audit rule and the cross audit rule, and the audit rules are executed simultaneously, so that the efficiency can be improved.
In one embodiment, the auditing the newly added service data through the data rule to obtain the auditing result includes: acquiring a corresponding data identifier in the data rule, and locating the position of the data identifier in the data rule; replacing the data identifier at the corresponding position in the data rule by the newly added service data corresponding to the data identifier; and executing the replaced data rule to obtain an auditing result.
Specifically, the server first obtains the data identifier at the position to be filled in the data rule, so as to extract corresponding data from the newly added service data according to the data identifier, and then fills the extracted corresponding data into the corresponding position to be filled in, so that after the data replacement is completed, the data rule has individuality, and the server can obtain the code of the corresponding data rule and then execute the code, that is, the server directly executes the data rule after the replacement is completed, so as to obtain the auditing result.
In the above embodiment, the data identifier refers to an identifier of each data in the newly added service data, such as a type of the data and a name of the data, and the server determines, according to the data identifier, a position of each data in the newly added service data corresponding to the data rule, and fills the newly added service data in the corresponding position, so that the server directly executes the data rule after the replacement is completed, and an audit result can be obtained, thereby improving the audit efficiency.
In one embodiment, after the sending the generated warning information to the checking terminal, the method further includes: receiving a data processing result returned by the checking terminal, wherein the data processing result is obtained by checking the goods of the corresponding service under the customs line; and when the data on the line is judged to be abnormal according to the data processing result, sending auditing information of the data abnormality to the participant terminal corresponding to the corresponding block chain link point, wherein the auditing information is used for indicating the participant terminal to inquire the non-uploaded service data associated with the abnormal newly-added service data and uploading the non-uploaded service data to the block chain.
Specifically, the embodiment mainly aims at the processing step of the newly added service data with problems, that is, when the newly added service data has problems, the newly added service data is sent to the inspection terminal, so that corresponding customs processing personnel can inspect the goods of the corresponding service offline to obtain a corresponding data processing result, when the data processing result is inconsistent with the online data, that is, when the online data has problems, the inspection terminal sends the data processing result to the server, the server can send abnormal data auditing information to the participant terminal corresponding to the corresponding block link point, so that the participant terminal inquires the non-uploaded service data associated with the newly added service data with problems, and uploads the non-uploaded service data to the block link, thereby ensuring the integrity of the data of each participant to prevent the problem that the participant fails to upload the complete data, and because the operations of uploading and modifying data of each participant are recorded on the block chain, the data counterfeiting of each participant is prevented.
In the above embodiment, when the newly added service data has a problem, whether the newly added service data really has a problem can be judged according to offline inspection of customs personnel, and if yes, the corresponding participant can upload the service data which is not uploaded, so that the integrity of the data is ensured.
In one embodiment, the method for processing service data based on a block chain may further include: downloading newly added service data from the block link points; inquiring the associated block link node according to the newly added service data and obtaining corresponding associated service data; and generating a declaration form according to the newly added service data and the associated service data, and sending the declaration form to the checking terminal.
Specifically, the automatic making process of the declaration form is related to, namely, the server can download the newly added service data from the block chain, and then inquire the associated block chain node according to the newly added service data and obtain the corresponding associated service data; generating a declaration form according to the newly added service data and the associated service data, and sending the declaration form to the checking terminal, so that the subsequent verification process of the declaration form can include: and acquiring corresponding data on the block chain nodes according to the declaration form, comparing the acquired data with the data on the declaration form, if the comparison is successful, the declaration form is approved, and otherwise, the declaration form is not approved.
In the embodiment, after the integrity of the data on the block chain is ensured, the declaration form is made, so that the accuracy of the declaration form is improved.
The technical solutions of the embodiments related to the block chain-based service data processing method are not limited to customs application scenarios, and can also be applied to other scenarios where inspection can be performed according to multi-party data to improve inspection accuracy.
