Description

Technical Field

[0001] The present invention relates to the field of blockchain and Internet of Things technology, and in particular to a method, system, device and storage medium for improving the credibility of blockchain evidence storage of commodity transaction data. Background Art

[0002] Commodity trading refers specifically to the wholesale market of bulk commodities that specializes in electronic trading and hedging. In the current bulk commodity warehouse receipt trading, the entry and exit of bulk commodities in the warehouse is controlled by the warehousing enterprise, and the funding party and the trading party cannot directly obtain the warehousing information. There is information asymmetry between the buyer and the seller, and it is difficult to track the change of ownership of the transaction subject, and there is a risk of tampering with the recorded data. At the same time, it also brings huge challenges to supervision. Summary of the invention

[0003] In view of the transaction risks existing in bulk commodity warehouse receipt transactions, the present invention proposes a method, system, device and storage medium for improving the credibility of bulk commodity transaction data blockchain evidence. By applying the present invention, the real-time acquisition of the storage status of goods can be achieved through the Internet of Things technology, and the goods can be automatically uploaded to the chain to eliminate the risks of human error and evil. The transaction and storage information registered through the blockchain can complete the credible verification in the blockchain, realize the change of goods ownership, provide credible certificates in the subsequent links such as goods out of the warehouse, and ensure the traceability of the whole process.

[0004] The object of the present invention is to achieve the following technical solution: a method for improving the credibility of commodity transaction data blockchain evidence storage, comprising the following steps:

[0005] (1) The customer submits his / her identity information to register an account on the IoT trading platform and conducts ID card face verification. After the verification is passed, the IoT trading platform will register the customer's identity information on the blockchain.

[0006] (2) The owner of the goods applies for the goods to be put into storage on the IoT trading platform and enters the goods information.

[0007] (3) After the goods arrive at the supervised warehouse, the IoT transaction platform first collects the identity information of the transport vehicle and personnel. After the identity information of the personnel is verified, the goods are allowed to enter the supervised warehouse.

[0008] (4) The IoT transaction platform calculates the cargo weight based on the vehicle weight minus the empty vehicle weight, verifies the weight through the swing data of the lifting equipment, and compares the cargo weight with the cargo information entered in step (2). If the comparison results are consistent, the data is uploaded to the blockchain. The uploaded data includes: cargo number, cargo weight, number of pieces, cargo owner, etc. If the comparison results are inconsistent, the cargo owner is notified and waits for confirmation.

[0009] (5) When the owner of the goods initiates a listing request on the IoT trading platform, the IoT trading platform calls the blockchain to number the goods to be listed and verify the owner of the goods.

[0010] (6) After the goods are verified on the blockchain, they are put on the shelves on the IoT trading platform. At the same time, the IoT trading platform locks the goods through the blockchain to prevent double spending of the goods.

[0011] (7) When the two parties reach a transaction agreement on the IoT transaction platform, the owner of the goods initiates the transfer of the goods ownership on the IoT transaction platform. After the change of the goods ownership, the IoT transaction platform registers the change of the goods ownership information through the blockchain.

[0012] (8) The buyer of the goods applies for the goods to be shipped out of the warehouse on the IoT trading platform and enters the corresponding goods information.

[0013] (9) When the buyer obtains the goods from the supervised warehouse, he or she needs to register the identity information of the person picking up the goods on the IoT trading platform and verify the identity by face recognition using the ID card.

[0014] (10) The IoT trading platform calculates the weight of the goods according to the number of pieces picked up, verifies the weight through the swing data of the lifting equipment, and compares it with the goods information in step (8). After the weight verification is passed, the IoT trading platform will initiate the registration of picking up the goods in the blockchain smart contract. If the goods are completely picked up, the smart contract will register the goods out of the warehouse; if the goods are partially picked up, the goods will be split through the smart contract, and two copies of the goods data will be obtained and the ID of the previous goods will be marked to facilitate the traceability of the goods. After the split, the picked up part of the goods will be registered for out of the warehouse, and the unpicked part of the goods will remain in the warehouse.

[0015] Furthermore, in step (1), the IoT trading platform is a platform for bulk commodity trading, which is a bulk commodity trading platform built based on blockchain, IoT, and face recognition to ensure the authenticity and security of transactions made by customers on the platform.

[0016] Furthermore, in step (2) and step (8), the cargo information includes cargo number, cargo type, weight and number of pieces.

[0017] Furthermore, in step (3), for transport vehicles, a camera is used to collect the vehicle license plate, and the vehicle weight is obtained on the weighbridge. For personnel identity information, it is entered by the IoT transaction platform and verified by the ID card face.

[0018] The present invention also provides a system for improving the credibility of blockchain evidence storage of bulk commodity transaction data, the system includes an account registration module, a goods information entry module, a goods information comparison module, a goods listing module and a goods ownership change module, a goods transaction module and a goods transaction information verification module; the client, the Internet of Things transaction platform end and the blockchain end interact through each module; the clients of the client include the goods owner and the goods buyer;

[0019] The account registration module is used for the client to submit identity information to the IoT trading platform to register an account and perform ID card face verification. After the verification is passed, the IoT trading platform will register the customer's identity information on the blockchain.

[0020] The cargo information entry module is used to enter the corresponding cargo information when the cargo owner who has completed registration on the IoT trading platform applies for cargo entry on the IoT trading platform. After the cargo arrives at the supervision warehouse, the IoT trading platform collects the identity information of the transport vehicle and personnel. After the identity information of the personnel is verified, the cargo is allowed to enter the supervision warehouse.

[0021] The cargo information comparison module is used to check cargo information when the cargo enters the supervision warehouse. The Internet of Things transaction platform calculates the cargo weight based on the vehicle weight minus the empty vehicle weight, and verifies the weight through the swing data of the lifting equipment. The cargo weight is compared with the cargo information entered by the cargo information entry module. If the comparison results are consistent, the blockchain end is chained. The chained data includes: cargo number, cargo weight, number of pieces, cargo owner, etc. If the comparison results are inconsistent, the cargo owner is notified and waits for confirmation.

[0022] The goods listing module is used by the goods owner to initiate a listing request on the IoT trading platform. The IoT trading platform calls the blockchain to number the goods to be listed and verify the goods owner. After the goods are verified by the blockchain, the goods are listed on the IoT trading platform. At the same time, the IoT trading platform locks the goods through the blockchain to prevent double spending of the goods.

[0023] The cargo ownership change module is used to record the cargo ownership transfer information initiated by the cargo owner on the IoT transaction platform after the transaction parties reach a transaction agreement on the IoT transaction platform. After the cargo ownership is changed, the IoT transaction platform registers the change of cargo ownership information through the blockchain.

[0024] The goods transaction module is used to record the goods information entered by the buyer when applying for the goods to be shipped out of the warehouse on the IoT transaction platform. The buyer obtains the goods from the supervision warehouse. During the process of picking up the goods, the buyer needs to register the identity information of the person picking up the goods on the IoT transaction platform and verify it through the ID card face.

[0025] The goods transaction information verification module is used to verify the transaction goods information when the goods buyer extracts the goods from the supervision warehouse, and compare it with the goods information recorded by the goods transaction module. The IoT transaction platform calculates the weight of the goods according to the number of pieces picked up, and verifies the weight through the swing data of the lifting equipment. After the weight verification, the IoT transaction platform will initiate the registration of picking up goods in the blockchain smart contract. If the goods are completely extracted, the smart contract will register the goods out of the warehouse; if the goods are partially extracted, the goods will be split through the smart contract, and two copies of the goods data will be obtained and the ID of the previous goods will be marked for the purpose of goods traceability. After the split, the picked-up part of the goods will be registered for out of the warehouse, and the unpicked part of the goods will remain in the warehouse.

[0026] Furthermore, the IoT trading platform is a platform for bulk commodity trading, which is built based on blockchain, IoT, and face recognition to ensure the authenticity and security of transactions made by customers on the platform.

[0027] Furthermore, the cargo information recorded by the cargo information entry module and the cargo transaction module includes cargo number, cargo type, weight and number of pieces.

[0028] Furthermore, after the goods arrive at the supervision warehouse, the license plate of the transport vehicle is collected by a camera, and the vehicle weight is obtained on the scale. The identity information of the personnel is entered by the IoT transaction platform and verified by the ID card face.

[0029] The present invention also provides a device, comprising:

[0030] one or more processors;

[0031] A memory for storing one or more programs;

[0032] When the one or more programs are executed by the one or more processors, the one or more processors execute the method for improving the credibility of blockchain evidence storage of commodity trading data.

[0033] The present invention also provides a computer-readable storage medium for storing one or more computer programs, wherein the one or more computer programs include program codes. When the computer programs are run on a computer, the program codes are used to execute the above-mentioned method for improving the credibility of blockchain evidence storage of commodity trading data.

[0034] Beneficial effects of the present invention:

[0035] 1. Verify the authenticity of the transaction parties through the face verification system. When goods are put in and out of the warehouse, face verification is carried out to ensure the authenticity of the goods entering the warehouse and the safety of the goods.

[0036] 2. Use IoT terminals to register data on goods, monitor the flow of goods, and ensure the authenticity of goods
