The data is stored in the block chain and cannot be tampered, authenticity of order data, payment order data and waybill data can be guaranteed, accordingly validity of three-order-to-one collision is guaranteed, the data stored in the block chain is encrypted, only a customs server with directional authorization can decrypt the data, and safety of the data is further guaranteed. The declaration main body 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the customs server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In one embodiment, as shown in fig. 2, a customs clearance data processing method 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 receiving customs clearance data sent by the declaration main body, wherein the customs clearance data carries an order identification, a payment order identification and an invoice identification.
Specifically, customs declaration data is sent to the customs server by a declaration main body, and the customs declaration data can be sent by an e-commerce platform, so that the customs declaration data can comprise a declaration list in which an order identification, a payment order identification and an invoice identification, as well as order data, payment data and invoice data, can be included.
The order identification is used for uniquely determining the order and can comprise an e-commerce identification and an order number, similarly, the payment identification comprises an order number and a payment company identification, and the waybill identification comprises an order number and a logistics company identification, so that three data can be summarized through the order number.
S204: and respectively obtaining encrypted order data, encrypted payment order data and encrypted waybill data from corresponding nodes of the block chain according to the order identification, the payment order identification and the waybill identification, wherein the encrypted order data, the encrypted payment order data and the encrypted waybill data are respectively uploaded by the e-commerce platform, the payment company and the logistics company and are pre-stored in the data at the corresponding nodes of the block chain.
Specifically, encrypted order data, encrypted payment order data, and encrypted waybill data at corresponding nodes of the blockchain are uploaded by the e-commerce platform, the payment company, and the logistics company, respectively. The customs server can acquire the e-commerce identification according to the order identification, and further download encrypted order data from a node corresponding to the block chain according to the corresponding relation between the e-commerce identification and the block chain link point, wherein the e-commerce identification is pre-stored in the database. Similarly, the customs server may obtain the payment company identifier according to the payment order identifier, and further download encrypted payment order data from the node corresponding to the block chain according to the correspondence between the payment company identifier and the block chain link point, which is pre-stored in the database. The customs server can acquire the logistics company identification according to the waybill identification, and further download encrypted waybill data from a node corresponding to the block chain according to the corresponding relation between the logistics company identification and the block chain link point stored in the database in advance.
The encrypted order data, the encrypted payment order data and the encrypted waybill data are periodically uploaded to a block chain by an e-commerce company, a payment company and a logistics company, and the three data are respectively uploaded, so that the pre-tampering of the three data is avoided.
S206: and acquiring a directional authorized decryption key corresponding to the encrypted order data, the encrypted payment order data and the encrypted waybill data.
Specifically, after obtaining the encrypted order data, the encrypted payment order data, and the encrypted waybill data downloaded from the blockchain, the customs server needs to perform a decryption operation on the encrypted order data, the encrypted payment order data, and the encrypted waybill data, and in order to ensure the security of the data, a decryption key corresponding to the decryption operation is authorized by a corresponding principal, for example, an e-commerce orients an authorization key to customs, a payment company, and a logistics company, a payment company orients an authorization key to customs and the e-commerce, and the logistics company orients an authorization key to customs and the logistics company. Therefore, the security of the decryption keys is ensured, and other companies without the decryption keys cannot acquire the decryption keys.
And in order to ensure the security of the decryption key, a decryption key calling mode can be set, namely, a key calling identifier is generated by encrypting the decryption key, the key calling identifier is directionally authorized to a specific main body, then when the specific main body needs to use the decryption key, the called main body actively submits the calling identifier and the identification code of the specific main body to the called main body, the called main body judges whether the calling identifier is correct, if so, whether the calling identifier is matched with the identification code of the specific main body, and if so, the calling of the decryption key is allowed.
S208: and decrypting the encrypted order data, the encrypted payment order data and the encrypted waybill data through the acquired decryption key of the directional authorization.
Specifically, after the customs server obtains the directional authorization key, the encrypted order data, the encrypted payment order data and the encrypted waybill data are decrypted to obtain the order data, the payment data and the waybill data.
S210: and performing cross validation on the decrypted order data, the decrypted payment data and the decrypted waybill data to obtain a cross validation result.
Specifically, after the customs server decrypts the order data, the payment data and the waybill data, cross-validation is performed on the three data, that is, whether the contents of specific fields in the three data are the same or not is compared to obtain a cross-validation result.
S212: and when the cross-validation result shows that the order data, the payment order data and the waybill data are inconsistent, increasing the inspection rate of the customs clearance article corresponding to the customs clearance data.
Specifically, customs officers can check the cross-validation result through the system, and for the business with completely consistent validation, the business can be divided into low-risk business to reduce the checking rate, and for the business with inconsistent cross-validation, the business can be divided into high-risk business to correspondingly improve the checking rate, so that the aim of accurate supervision is fulfilled.
According to the customs clearance data processing method, firstly, after the customs server receives clearance data sent by a declaration main body, order data, payment order data and waybill data can be obtained from corresponding nodes of a block chain, so that the data are changed into data with multiple sources, the data are stored on the block chain and cannot be tampered, authenticity of the order data, the payment order data and the waybill data can be guaranteed, validity of three-way collision is guaranteed, the data on the block chain are encrypted, only the customs server with directional authorization can decrypt the data, and safety of the data is further guaranteed.
Specifically, referring to fig. 3, fig. 3 is a flowchart of step S212 in the embodiment shown in fig. 2, where the step S212, namely, increasing the inspection rate of the customs clearance item corresponding to the customs clearance data, may include:
s302: and when the cross-validation result shows that the order data, the payment order data and the waybill data are inconsistent, calculating the deviation rate of the order data, the payment order data and the waybill data.
Specifically, the deviation ratio is a ratio of the number of data inconsistent in verification in order data, payment data, and waybill data to the total data number, for example, for this cross-verification, the number of times that the verification is required to be compared is used as a denominator, and then the number of times that the verification fails in the cross-verification process is counted, so that the deviation ratio = the number of times that the verification fails in the cross-verification process/the number of times that the verification is required to be compared.
S304: and acquiring preset grouped data, wherein the grouped data carries a deviation rate range label.
Specifically, the preset packets are divided according to the deviation ratio, if the deviation ratio is 0, the preset packets are normal packets, and then as the deviation ratio increases, corresponding packets are set, which in order to ensure that the number of data in each packet is relatively consistent, i.e. non-uniform packets can be performed, for example, as the deviation ratio increases, the step size of the packets can increase. Each packet carries a deviation ratio range label that includes a minimum and maximum value of the deviation ratio, thereby defining a range. And as the deviation ratio increases, the inspection rate also becomes larger.
S306: and grouping the customs clearance data according to the deviation rate range label and the deviation rate so as to group the customs clearance data with the deviation rate larger than a first threshold value into a set with a large inspection rate and group the customs clearance data with the deviation rate smaller than a second threshold value into a set with a small inspection rate.
Specifically, the server determines a corresponding deviation rate range label according to the calculated deviation rate, and then divides the customs data into the groups, so that the customs data with the deviation rate larger than a first threshold value can be grouped into a group with a large inspection rate, and the customs data with the deviation rate smaller than a second threshold value can be grouped into a group with a small inspection rate, wherein the first threshold value is larger than or equal to the second threshold value.
According to the embodiment, the customs clearance data is subjected to grouping processing according to the cross validation result, so that customs clearance data can be subjected to different inspection rates, and thus customs clearance efficiency can be improved by means of differential treatment.
In one embodiment, before the receiving the declaration data sent by the declaration subject, the method further includes: receiving uplink registration requests sent by each declaration main body; and deploying block chain nodes for each declaration main body according to the uplink registration request, and completing real-name authentication of each declaration main body through the deployed block chain nodes.
Specifically, the declaration main bodies may include an e-commerce company, a payment company and a logistics company, the declaration main bodies need to register on the block chain in advance to complete real-name authentication in order to upload corresponding data to the block chain, so that the data and the declaration main bodies can be associated, the customs server may allocate block chain nodes to the corresponding declaration main bodies after receiving a uplink request sent by the declaration main bodies, and then complete real-name authentication of each declaration main body through the allocated block chain nodes to obtain an electronic signature corresponding to each declaration main body, so as to perform encryption operation on uplink data, and the like, for example, before the declaration main bodies send the declaration data, the declaration data may be signed by the electronic signature to ensure security of the declaration data, and a public key of the electronic signature may be authorized to other main bodies, so that after the other main bodies obtain the declaration data, and obtaining the corresponding declaration data plaintext through public key signature.
The order data, the payment data and the waybill data can be uploaded in a mode that each declaration main body firstly encrypts the order data, the payment data and the waybill data through a key of each declaration main body, then each declaration main body calls an interface of a corresponding block chain link point to encrypt the order data, the payment data and the waybill data again respectively, and then the encrypted data are uploaded to a block chain. Therefore, the data stored in the block chain is also encrypted data, and the plaintext of the data cannot be acquired without the decryption keys corresponding to the declaration main bodies, so that the safety of the data is ensured.
Specifically, each participant (including roles of e-commerce enterprises, payment companies, logistics companies and the like) of the cross-border e-commerce business is added into a supply chain financing system based on a block chain, a system construction party deploys block chain nodes for each participant, and each participant completes the respective enterprise real-name authentication and acquires an electronic signature. Each participant of the cross-border e-commerce business uploads trade data produced during each trade business process in the system, specifically: the e-commerce platform uploads order information in the system; the payment company uploads payment order information in the system; the logistics company transmits the shipping bill information in the system.
The information uploading mode can be a manual input mode, and the service data in the ERP can be automatically synchronized to the block chain in a system docking mode. The manual input mode is that a customized developed application system is used, and after data is input, the application system calls the uplink interface; the system docking mode means that the user's own system directly calls the uplink interface. The calling of the uplink interface is to encrypt and uplink the data, and the electronic signature can be obtained during uploading.
In the above embodiment, each declaration main body is registered with a real name in the blockchain in advance, and the data and the declaration main body may be associated with each other.
In one embodiment, the directional authorization manner of the decryption key includes: receiving decryption keys sent by each declaration main body, and storing the decryption keys and the declaration main body identification in an associated manner; receiving an authorization main body sent by a declaration main body, and inquiring a declaration main body identifier corresponding to the declaration main body; and acquiring a decryption key corresponding to the declaration subject identifier, and sending the acquired decryption key to the authorization subject.
Specifically, the directional authorization of the key is that the customs server receives decryption keys sent by each declaration subject, stores the decryption keys and the declaration subject identifiers, and sends the decryption keys to other subjects specified by the current subject, so that other subjects can obtain corresponding data, for example, a payment company can obtain order data from a blockchain, and generate payment data after decrypting the order data.
In the above embodiment, the data existing on the blockchain is encrypted, and only the customs server authorized by orientation can decrypt the encrypted data, thereby ensuring the security of the data.
In one embodiment, the cross-verifying the decrypted order data, the payment data, and the waybill data to obtain a cross-verification result includes: performing cross validation on order data, payment data and waybill data through a first thread to obtain a first validation result; performing cross validation on the order data, the payment data, the waybill data and the customs declaration data through a second thread to obtain a second validation result; and generating a cross validation result according to the first validation result and the second validation result.
Specifically, the customs server first defines what data is to be verified between documents, such as the amount on the order being equal to the total amount on the bill(s) of payment, and such as the amount on the order being equal to the total amount on the bill(s). Secondly, the order number is contained in the payment order, and the order number is also contained in the freight note, so the customs server finds an order first, then finds the payment order (possibly a plurality of orders) and the freight note (possibly a plurality of orders) with the order number, and then finds the associated receipt. And finally, taking out data of the corresponding field, completing algebraic operation and logical operation, and completing verification.
In addition, the cross validation not only comprises the data collision among the three units, but also can verify the data in the declaration list. For example, the system compares the buyer on the order with the payer on the payment order, and also compares the buyer with the declaration list for the buyer field. For another example, the amount on the declaration form is cross-verified with the total amount on the order and the payment amount on the payment form, and the amount on the declaration form is cross-verified with the amount on the order and the amount on the shipping note.
Specifically, the first verification result and the second verification result may be a difference rate of matching, for example, if the data amount to be matched is a first number, and the data amount with unsuccessful matching is a second number, the first verification result and the second verification result may be expressed as a second number/the first number. The cross-validation result may be a maximum value of the first validation result and the second validation result.
In the embodiment, the cross validation is performed by a plurality of threads, so that the data processing efficiency can be improved.
It should be understood that although the various steps in the flow charts of fig. 2-3 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 2-3 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternating with other steps or at least some of the sub-steps or stages of other steps.
