Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a method and device for tracing the unique identification of pledged movable property based on blockchain. Background Art

[0002] Physical movable property is one of the important assets for pledge financing of small and medium-sized enterprises. If we can use advanced technologies such as blockchain to establish a unique identification and tracing method for pledged movable property, it will be easier for financial institutions to identify and trace pledged movable property rights. This will help to specify movable property, reduce the risk of repeated pledges, and ensure the safety of credit funds of financial institutions.

[0003] After searching the Chinese patent publication number CN113674084A, a movable property pledge financing method and system, equipment, and computer-readable storage medium based on blockchain are disclosed. Specifically, the data storage, information transparency, traceability, and non-tamperability characteristics based on blockchain are disclosed. All relevant transaction data and enterprise information storage are published on the blockchain. The document voucher can ensure the authenticity and reliability of the data after multi-party cross-verification, and then ensure that the movable property pledge is consistent with the enterprise's financing application and its ownership is undisputed, making the bank's pre-loan investigation more convenient and the investigation results more reliable; after the bank provides the loan, it provides a convenient method for the bank to conduct daily inventory inspections of pledged movables, so that the bank can achieve low-cost real-time monitoring, avoid the movable property being replaced and disposed of by the financing enterprise, and ultimately reduce the risk of the bank providing movable property pledge financing. However, the unique identification and tracing of pledged movables is not involved.

[0004] At present, some of the physical movables stored in the warehouse have original factory labels and product serial numbers, some have original factory labels but no product serial numbers, and some have no original factory labels. They can only be identified by centralized stacking. In either case, there is no unified unique identification of movables that can track and trace the pledge status. It is difficult to specify the corresponding pledged property and the property recorded in the pledge registration, especially in dynamic business scenarios, which can easily lead to the risk of repeated pledges. When litigation disputes arise, it is difficult for the judiciary to determine the ownership.

[0005] In summary, the existing pledged movables lack unique identification and traceability methods, resulting in high risks in pledge of movables and difficulty in conducting financing business. Summary of the invention

[0006] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and to provide a unique identification tracing method and device for pledged movable property based on blockchain.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0033] The present invention proposes a unique identification traceability scheme for pledged movables based on blockchain. The scheme is based on the full life cycle circulation of unique identification of movables on blockchain, and realizes the traceability, reviewability and tamper-proof of data. The movable financing demander, the physical movable custodian, the movable financing funder and the movable financing collaborative platform join the alliance chain, which ensures the security, authenticity, uniqueness, validity and integrity of the data between the participants of the movable unique identification, and promotes the development of movable financing business. The scheme of unique identification of movables based on blockchain is introduced in detail below.

[0034] Figure 1 : is a flow chart of a unique identification tracing method for pledged movables based on blockchain in an embodiment of the present invention. The nodes of each participant in movable financing constitute blockchain nodes, and the blockchain nodes include: movable financing demander nodes, physical movable custodian nodes, movable financing funding parties, and movable financing collaborative platform party nodes; Figure 1 As shown in the figure, the unique identification tracing method of pledged movable property based on blockchain includes the following steps:

[0035] Step S101: The movable property financing demander node initiates a warehousing application, constructs a pre-warehousing material information block, and adds the pre-warehousing material information block to the blockchain;

[0036] Step S102: The physical movable property custodian node confirms the warehousing information, takes out the material information according to the warehousing application work order, prints the movable property unique identification labels in batches through the printer, and automatically associates the material information and storage information to construct a one-object-one-code storage information block, and adds the storage information block to the blockchain;

[0037] Step S103: The movable property financing funding party node confirms the pledge information, completes the movable property financing pledge registration, associates the pledge registration information with the movable property unique identifier, constructs a pledge registration information block, and adds the pledge registration information block to the blockchain;

[0038] Step S104: The movable property financing collaborative platform authenticates the unique identifier of the movable property, verifies whether the unique identifier of the movable property is associated with the material information, storage information, and pledge registration information, and performs real-time status monitoring of the unique identifier of the movable property, constructs a traceable authentication information block, and adds the authentication information block to the blockchain.

[0039] The unique identification of movable property contains coded text and QR code graphics. The upper part is the unique identification code of movable property (starting with DC + 13 digits), the middle part is the QR code, and the lower part is the query website. Users can query the unique identification information by scanning the QR code or logging in to the website.

[0040] Figure 2 It is a schematic diagram of mapping unique identification information of movables based on blockchain in an embodiment of the present invention. The movable financing collaborative platform first collects underlying basic information according to the business progress. The first is the material information of the pre-warehouse node, including material name, material code, specification, model, manufacturer, batch, etc.; the second is the warehousing information of the entry and exit nodes, including entry time, entry quantity, storage location, exit time, exit quantity, inventory status, abnormal alarm, etc.; the third is the pledge information of the pledge registration node, including the pledger, custodian, pledgee, pledge registration certificate number, pledge contract number, pledge delivery time, etc.; the movable financing collaborative platform then uploads the three parts of information to the blockchain to ensure the security and authenticity of the information data flow process; the movable financing collaborative platform then associates the three parts of information with the unique identification through the background database, and binds and maps the three parts of information with the unique identification. Users can query and trace the full life cycle flow status of the pledged movable unique identification by scanning the QR code or logging in to the website.

[0041] In specific implementation, the solution provided by the embodiment of the present invention uses blockchain technology at the bottom layer, which can be composed of an Orderer (sorting) node, and each organization (such as movable property financing fund party 1, 2...) corresponds to multiple Peer nodes, and the organization unifies the authority control within the jurisdiction of the organization. According to specific business needs, multiple institutions can form a subchain (channel), which is a subset of all participants in the alliance chain.

[0042] In specific implementation, the blockchain SDK (software development kit) layer calls the interface of the blockchain bottom layer to transmit data between each other. The blockchain middle layer calls the interface of the blockchain SDK layer. The cargo owner application, the warehouse application, the financing collaboration platform application, and the funding application call the interface of the blockchain middle layer to transmit data between each other.

[0043] The following describes how to implement the present invention in conjunction with Table 1.

[0044] Table 1 is an implementation example of a unique identification and traceability method for movable property based on blockchain, including four process nodes: warehousing application, warehousing and shelving, pledge registration, and real-time monitoring. The pre-warehousing order, arrival registration material certificate, warehousing material certificate, shelving material certificate, pledge registration certificate, and warehouse receipt authentication information are uploaded to the chain in the form of hash summaries.

[0045] Table 1

[0046]

[0047] From the above, it can be seen that the unique identification tracing method of movable property based on blockchain provided by the present invention can realize the whole process tracing and confirmation of pledged movable property.

[0048] The beneficial technical effects of the technical solution provided by the embodiment of the present invention are: the circulation of unique identification of movable property based on blockchain is realized, and each movable property financing participant joins the alliance chain, which ensures the transparency, traceability and tamper-proof of data among the movable property financing participants, improves the security and efficiency of pledged movable property, and greatly promotes the development of movable property financing business.
