[0002] In the express logistics industry, there are over 100 million parcels circulating every day. If all of them are manually inspected, the cost will be high and the security cannot be guaranteed 100%. Blockchain is a decentralized distributed ledger that has attracted widespread attention for its strong security and decentralized model. It is essentially a distributed computing and storage system. Blockchain has multiple nodes. Different nodes reach consensus through certain computing rules, and store the transaction execution results after consensus in the form of blocks in the database. Multiple blocks constitute the blockchain.

[0003] In the data flow and logistics flow of over 100 million express deliveries, express delivery security that relies on security inspection machines, security inspectors, and managers of various centers or outlets to supervise constitutes a new technical model. Part of the security inspection is done by unpacking, and the other part is done by security inspection machines. The main way of transaction is to judge the legality and compliance of the delivered items by the appearance of the items. This model is completely based on the integrity of the security inspectors and will have greater risks. Summary of the invention

[0027] The above features and advantages of the present invention can be better understood after reading the detailed description of the embodiments of the present disclosure in conjunction with the following drawings. In the drawings, the components are not necessarily drawn to scale, and components with similar related properties or features may have the same or similar reference numerals.

[0029] Figure 2 A schematic diagram of the main components of an embodiment of a blockchain-based security information traceability system of the present invention is shown.

[0030] Figure 3 The operating flow chart of the blockchain-based security information tracing system of the present invention is shown. DETAILED DESCRIPTION

[0031] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. Note that the aspects described below in conjunction with the accompanying drawings and specific embodiments are only exemplary and should not be construed as limiting the scope of protection of the present invention in any way.

[0032] Figure 1 The structure principle of an embodiment of the security information traceability system based on blockchain of the present invention is shown. Figure 2 Shows the structure of the components that make up the system. Figure 1 and Figure 2 , the system of this embodiment includes: an application layer module, a protocol layer module, a data processing layer module and a blockchain database module.

[0033] The protocol layer module performs two-way transmission with the application layer module and the data processing layer module respectively, and the blockchain database module performs two-way transmission with the application layer module and the data processing layer module respectively.

[0034] The application layer module includes the item imaging module, the background control module and the transaction confirmation module. The application layer module provides a human-computer interaction interface to handle statistical analysis operations.

[0035] The object imaging module is used to receive information uploaded by the security inspection machines used in express branches, transfer centers, and post stations during normal operations.

[0036] The background control module is used to manage and control the security inspection machine, including supervision and cancellation of related transactions, but the transaction content cannot be modified. When the security inspection machine creates a block, the client it holds will automatically participate in the proof process. The client of the ordinary security inspection machine will retain the relevant data of the block as a basis for arbitration in case of disputes. The background control module is also configured to realize the formation and storage of blockchain and identify the legitimacy of items. In addition, it also handles other uncontrollable problems that occur in the system, such as the problem that there are few security inspection machines actually participating in the security inspection in a certain period of time and it is impossible to generate valid proof.

[0037] The transaction confirmation module is used to confirm the integrity and certainty of the transaction to confirm the completion of the transaction.

[0038] In addition, the application layer module also provides various blockchain-related interfaces, so that the data processing layer module can receive the required information and feedback the background processing results to both parties of the transaction. The interfaces provided by the application layer module include the interface for transferring transaction information to the data processing layer module and the status feedback interface for the current transaction uploaded to the blockchain. The transaction includes the following states during the chain process: transaction creation is completed and waiting to be written into the block, block verification is in progress, transaction is on the chain, etc.

[0039] The protocol layer module includes the Proof of Stake (PoS) module and the transaction protocol module. The protocol layer module is used to store and run the relevant protocols of the blockchain, as well as to store and call the consensus algorithm of the Proof of Stake module. The execution of the consensus algorithm is the core of the entire blockchain formation. There are strict management calling methods and interface implementation methods to prevent tampering, which may cause serious consequences such as malicious control of the blockchain formation.

[0040] The proof-of-stake module is configured to allow all participating users to reach a consensus, complete the verification of the block, and store the transaction records in the blockchain to ensure the authenticity of the transaction records. Participating users include security inspection machines, senders, recipients, and managers. They identify and process the items that pass through the security inspection machine and upload them to the corresponding platform. During the upload process, they prove the transaction information (after processing) with other participants. The system provides corresponding conditions and manages the transaction process. For the security inspection machine of one of the participating users, after the data identification is confirmed, a security inspection mark is added to the corresponding data. The received and processed transaction information will be stored and processed, and the information that fails the security inspection will also be stored and processed, and the user does not need to deliberately prove it.

[0041] Specifically, the generation of verifiers is changed from the age of coins as the weight of competition to image verification, and the corresponding ID of the verification result is used as the chip for the election of verifiers. The blockchain of the present invention is different from the traditional Bitcoin. The number of transactions stored in each block is relatively small, and the block generation speed is fast, which ensures the speed of transaction completion. The system of the present invention is subject to the security inspection machine involved in the transaction, so the transaction volume is much smaller than the Bitcoin platform, and the size of the blockchain formed by the present invention is also much smaller than the general blockchain, which is convenient for storage and backup.

[0042] According to the blockchain formed by transactions, the consensus algorithm adopts an improved PoS algorithm to speed up the formation of blocks and ensure the speed of transaction completion.

[0043] The proof of stake module solution consumes less resources and is relatively simple. It is more suitable for scenarios with greater randomness and more security inspection machines involved. The process is to verify the data on the platform after the transaction is completed ( va lid ator ), at this time all participants can reach a consensus and finally complete the block generation and upload to the blockchain.

[0044] The transaction protocol module is used for the storage and operation of the blockchain protocol.

[0045] The data processing layer module includes the blockchain database management module, the transaction record processing module and the data processing module. The data processing layer module is used to hash the transaction information records, generate block information, and return the block information to the equity proof module of the protocol layer module for verification. The data processing layer module is the core of the system, connected to each client, and is also responsible for reading and writing the complete blockchain database in the blockchain database module.

[0046] The blockchain database management module is used to record the important information generated in the blockchain database when the block creation is completed after the transaction is completed.

[0047] The transaction record processing module is used to record each transaction in the information transaction process.

[0048] The data processing module is used to process transaction information records and return block information to the equity proof module of the protocol layer module for verification.

[0049] Whenever a transaction is completed, the transaction record processing module of the database processing layer module records the information of the transaction confirmation module, and the data processing module hashes the transaction information confirmed by both parties, the security inspection machine and the relevant information of the package (pictures, etc.) to obtain a hash value.

[0050] The blockchain database management module in the data processing layer module broadcasts the transaction to the "local area network" composed of security inspection machines in the security information traceability system. The node network composed of security inspection machines proves the authenticity of the transaction.

[0051] The blockchain database module is divided into two parts, including the complete blockchain database managed by the security information traceability system and the client database of each participant terminal (i.e. Figure 2 The client database can store both the block information created by the security inspection machine and the complete blockchain information. The complete blockchain database of the security inspection information traceability system stores the complete blockchain content (complete node), while the client database stores the block header information (SPV-like node). Ordinary users can choose to store one of the databases.

[0052] Figure 3 The operation process of an embodiment of the security information traceability system based on blockchain of the present invention is shown. Figure 3At the beginning, the security inspection machine submits the express-related information and the user information of the security inspection machine (such as operator information, organization information, etc.), combines the private key signature information, generates transaction data, and submits it to the SDK (Software Development Kit) to determine whether it passes the endorsement verification. If it fails, the transaction is directly discarded and the data transaction ends. If it passes the endorsement verification, it will be submitted to the upper node and the node information will be generated and broadcast to each node. For transaction information that can pass the submission verification, the transaction record will be finally written into the block. If it cannot pass the submission verification, the transaction will be directly discarded and the data transaction ends.

[0053] After the submission verification is completed, the block is created and uploaded to the blockchain. In theory, the complete blockchain is only stored in the server of the security traceability system, and the security inspection machine only stores the relevant block information it participates in. Security inspection machines that meet specific requirements can be allowed to save complete blocks.

[0054] In a completed transaction, if any party raises doubts, or if both parties have objections or disputes about the transaction, the original block information can be obtained from the blockchain as evidence to resolve the dispute. To verify the authenticity of the evidence, the relevant data saved by the user who participated in the creation of the block at that time can be retrieved from the client's cache data for comparison to verify the authenticity of the evidence.
