Description

Block chain-based import and export warehouse shipment control method and system

Technical Field

One or more embodiments of the present disclosure relate to the field of information technology, and in particular, to a method and a system for controlling shipment of an import and export warehouse based on a blockchain.

Background

The import and export storage adopts a management scheme of paper receipts, and the receipts can be obtained according to paper receipts or warehouse receipts, so that the condition of counterfeiting the receipts or warehouse receipts to obtain the receipts exists, and huge rights and interests are lost to the import and export storage and the comprehensive service providers of the supply chain. Although an electronic import and export warehouse management scheme is proposed in the industry, the electronic data is easy to falsify due to nature, and the problem of low import and export warehouse security at present cannot be solved.

A blockchain is a chain of blocks each holding certain information that are linked into a chain according to the respective time sequence of generation. This chain is stored in all servers. These servers, referred to as nodes in the blockchain system, provide storage space and computational support for the entire blockchain system. If the information in the blockchain is to be modified, it is necessary to sign consent of more than half of the nodes and modify the information in all the nodes, which are usually held in different subject hands, so it is an extremely difficult thing to tamper with the information in the blockchain. Compared with the traditional network, the blockchain has two main core characteristics: firstly, the data is difficult to tamper, and secondly, the data is decentralised. Based on the two characteristics, the information recorded by the blockchain is more real and reliable, and can help solve the problem that people are not trusted each other. But currently, the blockchain technology is not applied to warehouse in-warehouse and out-warehouse verification of import and export storages.

The public-private key pair referred to in this specification relates to public and private keys in an asymmetric encryption algorithm. An asymmetric encryption algorithm refers to an encryption algorithm in which the encryption key and decryption key of one encryption algorithm are different or in which one key cannot be derived from the other. Asymmetric keys, also known as public key cryptography, encode information with two mathematically related keys. In this system, one of the keys, called the public key, is optionally issued to the person desiring to communicate securely with the key holder. The public key is used to encrypt the information. The second key is a private key belonging to the key holder. The key holder decrypts the received information with the private key. Exemplary are RSA algorithm, DSA algorithm, ECC algorithm, DH algorithm.

Industry business

The industry 20 referred to in this specification relates to a buyer entity that purchases imported goods. Import commerce is typically developed after being opened by a supply chain integrator, typically referred to as a domestic merchant or factory.

Supply chain integrator

The supply chain integrator referred to in this specification is concerned with providing an importation trade credit issuing service for an industry merchant 20.

Freight agent

The term forwarder as used in this specification relates to a forwarder service that provides trade services for importation services.

Warehouse business

The warehouse 10 referred to in this specification relates to a market subject who provides import and export warehouse 11 and stacking services in imports and countries.

Application scenario introduction

Import-export trade is also called international trade, and import-export trade flow mainly comprises: quotation, ordering, payment, stock, packaging, customs, shipping insurance, bill of lading, and pooling. The import and export trade process can be generalized to three stages of trade negotiations, contract fulfillment and delivery. In the trade consultation stage, firstly, the industrial business 20 makes a requirement, the export business is provided with inquiry or the buying intention is expressed by the intermediary business, and the export business directly provides the consultation to the industrial business 20; then, the exporter issues the plate to the industry manufacturer 20, the plate is returned by the industry manufacturer 20, and the plate is issued by the both parties to agree to 'accept' back and forth through the function of the both parties, then the plate is completed, the transaction is completed, the both parties complete the buying and selling condition agreement, the text is exchanged or the contract is signed, and the buying and selling procedure is completed. In the contract performance stage, the industry merchant 20 applies for import licenses, import visas, develops credit, deals with the FOBs, and guarantees with FOBs or C & F; the work of the export business is stock, transportation in the interior, the consignment of C & F or CIF conditions, the insurance water insurance of CIF conditions, export signing, business inspection and customs. During the delivery phase, the exporter is specified by credit. The shipping file is prepared to collect and withdraw the goods to a designated bank within the time specified by the credit card, or ask the bank to collect the goods (D/P, D/A); the industry provider 20 should prepare the ordered pick-up documents, prepare the customs clearance pick-up, and process notary inspection.

After the buyer and seller agree and sign the import-export contract, payment and delivery needs to be completed. The most used form of credit is the payment phase. The credit card is a written certificate which is opened to the exporter according to the request of the importer and ensures the responsibility of paying the goods. In the credit card, the bank authorizes the exporter to use the bank or the appointed bank as the payer under the condition of meeting the regulations of the credit card, issues a draft which cannot exceed the regulated amount, and takes the goods at the appointed place according to the regulated accompanying shipping bill. The flow of the credit card operation is briefly described as follows: (1) The buyer and seller specify the payment using the documentary credit in the trade contract; (2) The buyer informs the local bank (issuing bank) to open a credit card with the seller as beneficiary; (3) The issuing bank requests another bank to inform or guarantee the credit card; (4) the notification line notifies the seller that the credit card has been opened; (5) After the seller receives the credit card and ensures that the seller can fulfill the conditions specified by the credit card, the goods are loaded; (6) After the seller ships the goods, retrieving the positive bill of lading from the shipping company and making other documents; (7) The seller submits the document to a designated bank, which may be an issuing bank, or a payment, acceptance or bargaining bank designated within a credit card; (8) the bank verifies the document according to the credit card. If the bill meets the credit card regulation, the bank pays, accepts or negotiates according to the credit card regulation; (9) the bank other than the issuing bank sends the bill to the issuing bank; (10) After the issuing bank checks the bill without error, the bank which has paid, accepted or bargained according to the credit card is reimbursed in a form of pre-agreed; (11) The issuing bank communicates the buyer payment redemption form and pays the form after the buyer pays; (12) the buyer vouchers pick up goods to the shipping company.

After goods are carried to import and export warehouse agreed by buyer by freight agency, buyer needs to pay money to issuing bank, and take bill of lading out from import and export warehouse based on bill of lading. The import and export warehouse is a warehouse outsourcing service business established by profession aiming at import and export industry. Such warehousing services are different from ordinary warehousing services. Warehouse facilities must facilitate the assembly, cabinet loading, business inspection, etc. of the import and export goods. The warehouse is selected to be near major traffic intersections, distance terminals, container ports, air traffic airports.

Referring to fig. 1, the manufacturer 20 can not only deposit the money for clearing the goods at one time, but also deposit the money for clearing the goods at multiple times, and can extract the goods with corresponding share each time according to the deposited money. With the clearing of money, the imported goods can be gradually taken out of the warehouse, so that one-time import and export is realized. The bill of lading is a receipt for the business 20 to transact goods and the like. In shipping the goods, the industry 20 must hold the bill of lading, the case bill, and the invoice to pick up the goods.

At present, paper receipts are adopted for import and export storage, and the paper receipts or warehouse receipts can be used for carrying out goods, so that the situation of counterfeiting the receipts or warehouse receipts for carrying out goods exists, and huge losses are brought to import and export storage and industry merchants 20. Although an electronic import and export warehouse management scheme is proposed in the industry, the electronic data is easy to falsify due to nature, and the problem of low import and export warehouse security at present cannot be solved. For this reason, the specification provides a block chain-based import and export warehouse shipment control method and system.

Firstly, the present specification provides a method for controlling shipment of an import and export warehouse based on blockchain, which is executed by import and export warehouse control equipment, please refer to fig. 2, and includes the steps of:

step 102) receiving a warehousing request, wherein the warehousing request comprises a goods letter and a shipment audit configuration, the goods information records the names and the amounts of the goods, and the shipment audit configuration records a goods provider, a shipment audit party and an audit sequence;

step 104) generating identity credentials for each shipment auditor and distributing the identity credentials to the corresponding shipment auditor;

step 106) based on the warehouse-in request and the identity credential, generating warehouse-in information and uploading a blockchain;

step 108) receiving a shipment request, inquiring a blockchain to obtain shipment approval records and historical shipment information, wherein the shipment approval records are uploaded by the shipment auditors to the blockchain, and the shipment approval records comprise shipment volumes signed by the corresponding shipment auditors;

step 110), when the shipment approval record passes verification, based on the warehouse-in information, the historical shipment information, the goods lifting party, the goods name and the shipment volume, a warehouse-out operation bill and shipment information are generated, and the shipment information is uploaded to a blockchain.

Referring to fig. 3, fig. 3 illustrates an exemplary shipment auditor and audit sequence. The method specifically comprises the steps that the delivery application is uploaded after repayment by the industry merchant 20, the delivery application comprises audit signatures of a supply chain integrated merchant and a freight agent, and the delivery instruction is uploaded by the supply chain integrated merchant and comprises audit signatures of the industry merchant 20, the freight agent and the warehouse merchant 10. In other words, in this embodiment, the delivery auditor includes a supply chain integrator and a freight agent, and the delivery approval record includes the supply chain integrator approving the delivery application, the freight agent delivery application, the supply chain integrator approval delivery instruction, and the freight agent delivery instruction.

When the goods are delivered from the import and export warehouse, the industry merchant 20 needs to issue a pick-up application, and the pick-up application is validated after being checked by the supply chain integrator and the freight agent. The supply chain integrator will then issue a shipment order that needs to be validated by the industry merchant 20, freight agent and warehousing merchant 10. And after the ex-warehouse instruction takes effect, executing ex-warehouse, and storing the ex-warehouse execution information. According to the scheme provided by the embodiment, the operation of delivering the paper bill is separated, and the application, the verification and the execution of delivering the paper bill are realized in an electronic mode. The management and control efficiency of import and export warehouses is improved, meanwhile, the certificates are realized by means of blockchain to the goods-picking application and the warehouse-out instruction, and meanwhile, the industrial manufacturer 20, the freight agent and the warehouse 10 are checked and confirmed to record and store the certificates. The trusted operation record is realized, so that the operation behaviors of all parties can be truly recorded, effective credentials are formed, and the counterfeiting behaviors of bill of lading and warehouse bill are stopped.

In another aspect, referring to fig. 4, in another embodiment, a method for generating identity credentials for each shipment auditor and distributing the identity credentials to the corresponding shipment auditor includes the steps of:

step 202) generating a plurality of public and private key pairs and incorporating the public and private key pairs into a key group, generating a plurality of key groups, wherein the number of the public and private key pairs included in the key group corresponds to the number of shipment auditors, and sorting the public and private key pairs in the key group according to an audit order;

step 204) starting from the second public-private key pair, calculating the quotient of each public key and the previous public key respectively, and recording the quotient as a substitute public key;

step 206) distributing the first public-private key pair to a first shipment auditing party in the auditing order, and transmitting the substitute public key and the corresponding private key to a subsequent shipment auditing party;

step 208) the public key of the first shipment auditor in the audit sequence is included in the warehousing information, and the substitute public key is included in the shipment audit record.

And generating a plurality of key sets, and after the operation document and shipment information are generated once, replacing keys in the next key set, and carrying out identity credentials of a shipment auditing party of next shipment.

Asymmetric encryption algorithms require two keys to encrypt and decrypt, the two keys being a public key and a private key. Public keys are abbreviated as public keys and private keys are abbreviated as private keys. Encrypting predetermined content using a private key is known as signing, and is an electronic non-repudiated form of identity indication. The signature is verified using the corresponding public key.

In another embodiment, referring to fig. 5, the method for verifying the shipment approval record includes:

step 302), sorting the shipment approval records according to the time sequence of uploading the blockchain, and recording the shipment approval records as a sequence to be verified;

step 304) sequentially verifying the shipment auditor signature of the shipment approval record contained in the sequence to be verified, wherein the shipment approval record passing the signature verification is recorded as a valid shipment approval record;

step 306) when the valid shipment approval records included in the sequence to be verified cover all shipment auditors included in the audit sequence, judging that the shipment approval records pass verification.

And after receiving the goods-picking application sent by the industry merchant 20, notifying the corresponding supply chain integrator and freight agent to check and audit, and then checking the signature of the supply chain integrator and freight agent on the goods-picking application, uploading the corresponding checking signature associated with the goods-picking application to the blockchain for storage according to the request of the industry merchant 20 after the checking signature is gathered. After receiving the delivery instruction sent by the supply chain integrator, notifying the corresponding industry merchant 20, freight agent and warehouse 10 to check and audit, and then the industry merchant 20, freight agent and warehouse 10 carry out audit signature on the delivery instruction, and after the audit signature sets, uploading the delivery instruction to the blockchain for storage in association with the corresponding audit signature according to the request of the supply chain integrator. At this time, the manufacturer 20 needs to verify the type of the shipment, the number of the shipment, and the import/export warehouse of the shipment, which are related to the shipment instruction, and sign the verification. If the verification is not successful, the signature is not performed, and the platform informs the supply chain integrator that the verification of the delivery instruction is not passed and requests the supply chain integrator to reinitiate the delivery instruction. Referring to fig. 6, the shipment approval records are formed according to the audit sequence, so as to form an effective shipment approval record. And (5) forming an invalid shipment approval record according to the shipment approval record which is not performed according to the auditing order.

In another aspect, in further embodiments, a method of verifying a shipment auditor signature of the shipment approval record includes the steps of:

traversing each shipment approval record starting from the first shipment approval record of the sequence to be verified, and executing the following steps for each shipment approval record:

calculating the product of the substitute public key contained in the current shipment approval record and the substitute public key of the shipment approval record sequenced in front, multiplying the product by the public key contained in the warehousing information, and recording the product as the current public key;

and decrypting the signature contained in the current shipment approval record by using the current public key, judging that the signature verification of the shipment auditor of the current shipment approval record passes when the shipment volume can be successfully decrypted, and eliminating the current shipment approval record from the sequence to be verified when the shipment volume can not be successfully decrypted.

In another aspect, in a further embodiment, the tracking information includes the alternate public key. The private key and the public key of the asymmetric encryption algorithm are integers, and the secp256k1 algorithm in the ECC algorithm generates a private key with a length of 256 bits and a public key with a length of 512 bits. The public key is divided to produce a quotient having a decimal place, i.e., the alternate public key has a decimal place. The substitute public key is reserved with enough decimal places, so that the product of the substitute public key and the previous public key can be just obtained after rounding the decimal part.

When the embodiment is adopted, when the previous shipment approval record is not uploaded, the corresponding substitute public key is not disclosed, so that the corresponding public key of the next shipment approval record cannot be calculated, and even if the corresponding shipment auditor has uploaded the shipment approval record, the corresponding shipment auditor cannot be verified due to the fact that the public key is not available. Thus, jumping changes in shipment approval are technically prevented. That is, when one of the shipment auditors does not upload the shipment approval record, the subsequent shipment auditors in the audit order technically cannot upload the valid shipment approval record.

In another embodiment, referring to fig. 7, a method for generating a shipment operation document and shipment information based on the warehouse-in information, the historical shipment information, the shipper, the shipment name and the shipment amount includes:

step 402), calculating the current cargo residual quantity according to the warehouse-in information and the historical cargo outlet information;

step 404) taking the smaller value of the current cargo residual quantity and the cargo output quantity as the cargo output quantity;

step 406) generating a shipment operation bill and shipment information based on the delivery party, the shipment name and the current shipment amount.

In another aspect, the present disclosure provides a blockchain-based import and export warehouse shipment control system, referring to fig. 8, comprising:

The present description also provides a computer-readable storage medium having instructions stored therein, which when executed on a computer or processor, cause the computer or processor to perform one or more steps of the above embodiments. The above-described constituent modules of the electronic apparatus may be stored in the computer-readable storage medium if implemented in the form of software functional units and sold or used as independent products.

The technical features in the present examples and embodiments may be arbitrarily combined without conflict.

In the above embodiments, it may be implemented in whole or in part by software, hardware, firmware, or any combination thereof. When implemented in software, may be implemented in whole or in part in the form of a computer program product. The computer program product includes one or more computer instructions. When loaded and executed on a computer, produces a flow or function in accordance with embodiments of the present description, in whole or in part. The computer may be a general purpose computer, a special purpose computer, a computer network, or other programmable apparatus. The computer instructions may be stored in or transmitted across a computer-readable storage medium. The computer instructions may be transmitted from one website, computer, server, or data center to another website, computer, server, or data center by a wired (e.g., coaxial cable, fiber optic, digital subscriber line (Digital Subscriber Line, DSL)), or wireless (e.g., infrared, wireless, microwave, etc.). The computer readable storage medium may be any available medium that can be accessed by a computer or a data storage device such as a server, data center, etc. that contains an integration of one or more available media. The usable medium may be a magnetic medium (e.g., a floppy Disk, a hard Disk, a magnetic tape), an optical medium (e.g., a digital versatile Disk (Digital Versatile Disc, DVD)), or a semiconductor medium (e.g., a Solid State Disk (SSD)), or the like.

When the method is realized by hardware and firmware, the method flow is programmed into a hardware circuit to obtain a corresponding hardware circuit structure, so as to realize corresponding functions. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (FieldProgrammableGateArray, FPGA)) is an integrated circuit whose logic function is determined by the programming of the device by a user. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented with "logic compiler" software, which is similar to the software compiler used in program development and writing, and the original code before being compiled is also written in a specific programming language, which is called hardware description language (HardwareDescription Language, HDL), but also HDL is not just one, but a plurality of. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.

The above-described embodiments are merely preferred embodiments of the present disclosure, and do not limit the scope of the disclosure, and various modifications and improvements made by those skilled in the art to the technical solutions of the disclosure should fall within the protection scope defined by the claims of the disclosure without departing from the design spirit of the disclosure.
