After the server 120 performs the digital signature on the customs clearance object inspection record form by the first inspection node 110 to obtain the first digital signature, and uploads the first digital signature to the blockchain system, the server needs to receive the second digital signature aiming at the tax payment inspection information, which is sent by the second inspection node 130 of the blockchain system. Specifically, the second verification node 130 may first obtain the tax payment book corresponding to the customs declaration information, and the actual tax payment information of the customs declaration information is checked according to the tax payment book to obtain tax payment checking information (such as checking whether the time and amount requirements of the tax payment book are met), after the tax payment examining information is obtained, the second examining node 130 digitally signs the tax payment examining information to obtain a second digital signature, the tax payment verification information and the corresponding second digital signature may then be fed back to the server 120, and after receiving the tax payment verification information and the second digital signature by the server 120, the second digital signature and the tax payment checking information can be simultaneously uploaded to a blockchain system for storage, the information is prevented from being maliciously tampered, and the traceability of the relevant inspection information of the declaration form is achieved.
Step S205, a customs clearance processing result of the customs clearance information is obtained based on the preliminary verification data, the customs clearance number, the first digital signature and the second digital signature stored in the block chain system.
Specifically, the server 120 may recheck the inspection states of the inspection processes of the customs declaration information, for example, whether the inspection of all the inspection nodes has been performed, whether the inspection information is missing, or the like, and if the inspection of all the inspection nodes is completed and the inspection information is not missing, the corresponding customs declaration processing process may be ended, and the customs declaration processing result is obtained as the customs declaration processing completion.
In one embodiment, the step may specifically include: acquiring a plurality of pieces of inspection state information respectively corresponding to the preliminary inspection data, the customs clearance number, the first digital signature and the second digital signature; and if the plurality of pieces of inspection state information are in the normal state, setting the report processing result as report processing completion.

After acquiring the customs clearance information to be processed, if the preliminary inspection result of the customs clearance information is inspection passing, uploading the corresponding preliminary inspection data, customs clearance serial number and customs clearance information to a block chain system for storage, receiving a first digital signature aiming at a customs object inspection record list sent by a first inspection node and receiving a second digital signature aiming at tax payment inspection information sent by a second inspection node, and finally obtaining the customs clearance processing result of the customs clearance information based on the preliminary inspection data, the customs clearance serial number, the first digital signature and the second digital signature stored in the block chain system, wherein the scheme can upload information related to the customs clearance processing flow to the block chain for storage to prevent the related information from being maliciously tampered, particularly prevent the inspection information from being forged, the reliability of the customs declaration information processing is improved.
In one embodiment, the customs clearance information may include an electronic customs clearance and a declaration associated with the electronic customs clearance; the customs clearance information processing method based on the block chain can further comprise the following steps:
verifying the authenticity of the electronic declaration form and the declaration data to obtain a first verification result; if the first check result is that the check is passed, the consistency check is carried out on the electronic declaration form and the declaration data to obtain a second check result; if the second check result is that the check is passed, performing delayed report check on the electronic declaration form and the declaration data to obtain a third check result; and if the third verification result is that the verification is passed, setting the preliminary verification result of the customs declaration information as that the verification is passed.
In this embodiment, the server 120 may perform a preliminary inspection on the electronic declaration form and the declaration data associated with the electronic declaration form, and in order to accurately inspect the declaration form information to ensure the reliability of processing the declaration form information, the flow of the preliminary inspection may sequentially include an authenticity check, a consistency check, and a delayed declaration check. Specifically, the server 120 may perform an authenticity check on the electronic declaration form and the declaration data to obtain a first check result, that is, check authenticity of the related information material, for example, the invoice has a two-dimensional code link, and may automatically capture the first check result and then query the first check result in the official system. If the first verification result is a verification pass, the server 120 may then perform a consistency verification on the electronic declaration form and the declaration data to obtain a second verification result, i.e., detect whether the related document information matches, such as whether the items, quantities, and amounts in the list of documents of a batch of goods are consistent. And if the second check result is that the check is passed, performing delayed report check on the electronic declaration form and the declaration data to obtain a third check result, namely checking whether the report is delayed or not, and comparing the document identification date with the current date to obtain a check result. Finally, if the third verification result obtained by the server 120 is a verification pass, the preliminary verification result of the customs clearance information may be set as a verification pass.
Further, when the preliminary check result of the customs clearance information passes the check, the server 120 may further generate preliminary check data of the customs clearance information according to the first check result, the second check result, and/or the third check result, and allocate a customs clearance number to the customs clearance information. Specifically, the server 120 may generate corresponding preliminary verification data from the first verification result, the second verification result, and the third verification result, and the preliminary verification data may include first preliminary verification data corresponding to the first verification result, second preliminary verification data corresponding to the second verification result, and third preliminary verification data corresponding to the third verification result, and the preliminary verification data may include data of the verification result itself, verification time, verification-related persons, verification items, and the like.
In other embodiments, if the first verification result, the second verification result, or the third verification result is verification failed, the server 120 may set the preliminary verification result of the customs declaration information as verification failed and generate preliminary trial error information. In this embodiment, when any one of the first verification result, the second verification result and the third verification result is failed in verification, it may be determined that the initial review is failed, and corresponding error information is prompted, so that relevant personnel may perform corresponding processing, for example, re-verify a failed link, and the like.
In one embodiment, before receiving the first digital signature for the declaration object ping record sent by the first ping node of the blockchain system in step S203, the method may further include:
and sending a first inspection request to the first inspection node, so that the first inspection node acquires the preliminary inspection data, the customs declaration form number and the customs declaration form information stored in the block chain system according to the first inspection request, determines a target customs declaration object according to the preliminary inspection data, the customs declaration form number and the customs declaration form information, inspects the target customs declaration object to obtain an inspection result, and generates a customs declaration object inspection record form corresponding to the result type of the inspection result.
In this embodiment, before receiving the first digital signature for the customs clearance examination record sent by the first ping node 110, the server 120 may send a first ping request to the first ping node 110 to request the first ping node 110 to perform the ping processing on the customs clearance information. Specifically, after receiving the first inspection request, the first inspection node 110 may obtain corresponding preliminary inspection data, customs declaration number and customs declaration information from the block chain system according to the first inspection request, determine the target customs declaration object according to the preliminary inspection data, customs declaration number and customs declaration information, and inspect the target customs declaration object to obtain an inspection result, for example, the first inspection node 110 may perform inspection of a customs code, a price, a place of origin and an actual cargo, during the inspection process, may perform inspection by using a camera or other machine, and the given inspection result may include multiple result types, such as pass, false report, concealed report or declaration, and after obtaining the result type (one of pass, false report, concealed report or unproduction) of the inspection result, the first inspection node 110 may generate a customs declaration object record sheet corresponding to the result type of the inspection result (for example, an electronic version may be formed) Customs inbound and outbound shipments checknotes) may then be digitally signed by the inspection operator at the first inspection node 110 via private key encryption techniques. In the solution of this embodiment, the first ping request may be sent to the first ping node 110, so that the first ping node 110 accurately ping the related target customs clearance object, and generates a corresponding customs clearance object ping record according to the result types of different ping results, where the customs clearance object ping record may be uplink-stored by the first ping node 110, or may be sent to the server 120 and uplink-stored by the server 120, so as to ensure the reliability of processing the customs clearance information.
In one embodiment, before receiving the second digital signature for the tax payment verification information sent by the second verification node of the blockchain system in step S204, the method may further include:
and sending a second checking request to a second checking node so that the second checking node generates a corresponding tax payment book according to the customs declaration information stored in the block chain system according to the second checking request, and checking the actual tax payment information according to the payment time limit information and the payment amount information in the tax payment book when the actual tax payment information corresponding to the customs declaration information is identified to obtain the tax payment checking information.

Specifically, after receiving the second inspection request sent by the server 120, the second inspection node 130 may obtain customs declaration information from the blockchain system according to the second inspection request and generate a corresponding tax payment book. The tax payment book with built-in general template can be automatically generated according to the information of exemption property, exemption proportion/settlement mode, unit price, total price, currency value and the like in the customs declaration form and the actual checking result, the batch of goods can be calculated according to the class, quantity, price, production place and source place of the goods, the class, tax rate, total tax amount and latest tax payment term are filled in the batch of goods, the batch of goods can be generated, the batches of goods can be continuously waited for payment if the batch of goods is qualified, and other abnormal conditions can be warned. Then, when the second checking node 130 can identify the actual tax payment information corresponding to the customs declaration information, that is, when the tax payment is identified, the second checking node 130 can check the actual tax payment information according to the payment time limit information and the payment amount information in the tax payment book, so as to obtain the tax payment checking information. For example, the second checking node 130 may check whether the actual payment amount meets the time and amount requirement of the tax payment book, and if the actual payment amount meets the condition such as whether the full amount is paid, a charging bill, an actual exemption, and a tax collection condition may be generated after the condition is met, where the charging bill is generally a paid voucher or invoice, and the collection condition is a payment book and an actual payment result, so as to obtain the tax payment checking information, and a digital signature is performed on the second checking node 130 by a corresponding operator. In the solution of this embodiment, the second checking request may be sent to the second checking node 130, so that the second checking node 130 may accurately check the tax payment condition of the related target customs clearance object, and obtain corresponding tax payment checking information, where the tax payment checking information may be chain-linked by the second checking node 130, or may be sent to the server 120 and chain-linked by the server 120, so as to ensure the reliability of processing the customs clearance information.
