In addition, in the description of the present invention, "a plurality" means two or more unless otherwise specified.
FIG. 1 is a schematic diagram of a manifest data management system of an embodiment of the present disclosure. As shown in fig. 1, the warehouse receipt pledge system of the embodiment of the present disclosure includes a logistics storage node 1 (a first node), a pledge requester node 2 (a second node), a goods seller node 3 (a third node), a lender node 4 (a fourth node), and a storage and certification platform node 5 (a fifth node). The nodes are communicatively connected to each other, and preferably, the nodes may each be connected to the internet, communicating with each other through the internet. Meanwhile, each node is also a node in the pledge block chain network, and information can be recorded in a distributed mode based on the same block chain. Meanwhile, the logistics storage node 1 is also another block chain, that is, a terminal in the logistics block chain, and can query information recorded on the logistics block chain.
In this embodiment, the logistics block chain is a distrust-free block chain network set by the warehouse logistics enterprise to ensure the reliability of the logistics information, and nodes in the logistics block chain upload changes of the warehouse to the logistics block chain every time, so as to ensure that the whole course of the storage and transportation process of the logistics can be traced. The logistics storage node 1 is a terminal in the logistics block chain even though a full-function node on the pledge block chain network is provided. Therefore, the logistics block chain can inquire the physical state information of the trusted goods on the logistics block chain to generate a trusted warehouse bill.
It will be appreciated that the nodes in this embodiment are general purpose data processing apparatus having stored thereon predetermined computer program instructions for implementing predetermined functions when executed. The nodes can be desktop computers, portable computers, servers, workstations, intelligent mobile terminals and other devices.
FIG. 2 is a flow chart of a method of manifest data management in an embodiment of the present disclosure. As shown in fig. 2, the method for managing the manifest data of the present embodiment includes:
step S100, the pledge requester node 2 and the goods seller node 3 interact with an electronic sales contract with a digital signature and upload the information of the electronic sales contract to a pledge block chain for storage.
FIG. 3 is a flow chart of electronic contract interaction with an embodiment of the disclosure. As shown in fig. 3, the process of the pledge requester node 2 and the goods seller node 3 interacting with the goods sales contract with the digital signature may include:
step S110, the goods seller node 3 generates an electronic sales contract, and performs digital signature on the electronic sales contract to obtain a digital signature a.
The electronic sales contract may be text data describing the content of the sales contract, image data describing the content of the sales contract, or other forms of data defined according to a predetermined manner, such as a file structure or an XML file defined by JASON.
A digital signature is some data appended to a data unit or a cryptographic transformation performed on a data unit. Such data or transformations allow the recipient of the data unit to verify the source of the data unit and the integrity of the data unit and to protect the data against counterfeiting by a person (e.g., the recipient). Common digital signature algorithms include RSA, ElGamal, Fiat-Shamir, Guillou-Quisquarter, Schnorr, Ong-Schnorr-Shamir digital signature algorithm, Des/DSA, elliptic curve digital signature algorithm, finite automaton digital signature algorithm and the like. The digital signature technique is to encrypt the digest information with the sender's private key and transmit it to the receiver together with the original text. The receiver can decrypt the encrypted digest information only by using the public key of the sender, and then generates a digest information for the received original text by using the hash function, and compares the digest information with the decrypted digest information. If the two information are the same, the received information is complete and is not modified in the transmission process, otherwise, the information is modified, and therefore the digital signature can verify the integrity of the information.
In step S120, the goods seller node 3 sends the electronic sales contract, the digital signature a of the electronic sales contract, and the public key a corresponding to the digital signature to the pledge requester node 2 (i.e., the goods buyer).
Step S130, the pledge requesting party node 2 verifies the electronic sales contract through the public key a and the digital signature A, and if the electronic sales contract passes the verification, the electronic sales contract is digitally signed by using the private key of the pledge requesting party node 2.
Step S140, the pledge requester node 2 sends the digital signature B and the corresponding public key B to the goods seller node 3.
And step S150, the goods seller node 3 verifies the digital signature B sent by the pledge requester node 2, and after the verification is passed, the interaction of the electronic contract is completed.
That is, the electronic sales contract is digitally signed by the goods seller node 3, verified and signed by the pledge requester node 2, and then the confirmation of both the sales and purchase is completed. In order to prevent the buyer and the seller from communicating with the logistics company for deceiving loan, the sales contract needs to be uploaded to a pledge chain for storage to ensure that the source of the warehouse bill, namely the buying and selling of the goods, is documented. Meanwhile, through the above interaction, both the seller (goods seller node 3) and the buyer (pledge requester node 2) know the digital signature of the other party and the electronic signature of the seller itself for the electronic sales contract. Thus, the evidence can be stored from any party.
Fig. 4 is a flowchart illustrating a block chain verification process according to an embodiment of the disclosure. The following description will be given taking information of the certified electronic sales contract as an example. As shown in fig. 4, the process of performing block chaining verification in this embodiment includes:
and step S160, uploading the electronic sales contract to the evidence storage platform node 5.
During the certification process, the digital signatures and public keys of both parties can also be uploaded to the certification platform node 5 to represent the signing of the electronic sales contract by both parties.
And step S170, recording the abstract of the electronic sales contract on the pledge block chain by initiating one-time block chain transaction.
In particular, blockchain transactions may be initiated by either of the acquirer seller node 3 and the pledge requester node 2.
In the blockchain technology, any node can record all transaction histories and can route information such as transaction data transmitted by other nodes to more nodes. In a blockchain network, a new transaction can be created between any two nodes, the transaction propagates in a point-to-point (P2P) manner, and all nodes in the blockchain network verify the transaction. The result of the verification is also propagated in a point-to-point manner, so that all nodes write transactions into the blockchain. Thereby, a distributed transaction record is formed.
Specifically, in step 1, a party a in a transaction signs a digital signature to the opposite party in the transaction by using its private key, and attaches the signature to the tail of the transaction information to make a transaction order.
In step 2, A broadcasts the transaction list to the whole network, and each received node incorporates the received transaction information into a block. The transaction is successfully recorded until the block confirmation is successful.
And 3, each node creates a new block through a competition mechanism.
Specifically, the right to create a new block can be obtained by each node competing to solve a mathematical puzzle.
And 4, when one node wins the competition, broadcasting all the transaction records with the time stamp of the block record to the whole network, and checking by other nodes of the whole network. Where the timestamp is used to verify that a particular block is present at a particular time. Various ways may be employed to ensure consistency of timestamps for different nodes.
And 5, checking the accounting correctness of the block by other nodes in the whole network, and if the accounting correctness is confirmed, competing for the next block after the legal block, thereby forming a block chain for legal accounting.
In the process of one blockchain transaction, the transaction information is also recorded on the blockchain (namely, recorded in the blockchain account book of each blockchain node), so that the function of evidence storage can be realized by embedding information needing to be subjected to evidence storage in the transaction information.
In the present embodiment, the certification of the electronic sales contract is realized by recording the digest of the electronic sales contract on the pledge block chain and cooperating with the electronic sales contract stored on the certification storing platform node 5. The digest is obtained by calculating the data content through a message digest algorithm or a Hash (Hash) algorithm. In this embodiment, the digest may be computed using a variety of existing hashing algorithms, including SHA1, SHA256, SHA384, SHA512, RIPEMD, PANAMA, TIGER, ADLER32, and the like. A hashing algorithm (i.e., a hashing algorithm) is used to map an arbitrary length binary value to a shorter, fixed length binary value, this small binary value being referred to as a hash value. Hash values are a unique and extremely compact representation of a piece of data as a value. If a piece of plaintext is hashed and even if only one of the bits is changed, the corresponding hash value (or digest) will be a different value. It is computationally infeasible to find two different inputs whose hash is the same value, so the hash value of the data can verify the integrity of the data.
The vouching platform node 5 may be a node in a pledge blockchain network. This facilitates its acquisition of a summary of the electronic sales contract through a broadcast step in the blockchain transaction and its storage in verified pairs with the stored electronic sales contract.
Subsequently, any pledge blockchain node may request the verification platform node 5 to verify whether the electronic sales contract exists according to the digest of the electronic sales contract recorded in the blockchain ledger, and may request to acquire data of the electronic sales contract. Similarly, other subsequent data needing to be stored can also be stored in a similar manner. These credentialing data can also be verified by subsequent requests.
Step S200, the logistics storage node 1 inquires physical state information of goods in the logistics block chain and generates an electronic warehouse receipt.
Wherein the physical state information may include location information of the cargo. Preferably, the storage condition information of the goods can be further included. The physical state information of the goods is maintained through the logistics block chain, so that the situation that the logistics storage company interior personnel forge the bill by inputting false information can be prevented.
It should be understood that the logistics blockchain and the pledge blockchain are two different blockchain networks. The logistics storage node 1 is a node of the pledge block chain and is also a terminal of the logistics block chain, and can query information of the logistics block chain to obtain trusted physical state information of goods.
Meanwhile, in order to prevent the logistics storage company and the pledge from communicating to issue false bills. The logistics warehousing node 1 may be configured such that it can only generate electronic warehousing statements triggered by the electronic sales contract information documented on the chain of pledges. The arrangement ensures that an actual electronic sales contract is required to generate the electronic warehouse receipt for mortgage, thereby further increasing the safety of data management of the whole process.
And step S300, the logistics storage node 1 sends the electronic warehouse bills to the pledge request party node 2 and the goods sales node 3, and uploads the electronic warehouse bills to the pledge block chain for storage. This allows the electronic manifest to be queried for all pledget block link points. Therefore, the electronic warehouse receipt can be guaranteed to be not counterfeitable. Meanwhile, since the electronic bills are associated with the prior electronic sales contracts. Therefore, the electronic warehouse slip and the corresponding electronic sales contract can be associated with the certificate during the certificate storage, and the subsequent counterfeiting difficulty is higher.
Specifically, the electronic warehouse slip may include an identifier or a summary of the corresponding electronic sales contract, so that the association may be credited by a subsequent crediting process. Optionally, the logistics storage node 1 may associate the electronic warehouse slip with the corresponding electronic sales contract when uploading the electronic warehouse slip to the chain of mass preservation blocks for storage, that is, embed the summary of the electronic warehouse slip and the identifier or the summary of the corresponding electronic sales contract in the transaction information.
Preferably, the logistics warehousing node 1 is configured to start storing evidence after receiving the confirmation information sent by the goods sales node 3. Therefore, the authenticity of the electronic bill can be confirmed again by the goods sales node 3, the safety is further enhanced, and the difficulty of counterfeiting the electronic bill is increased.
Step S400, the pledge node 2 sends a pledge request to the lender node 4 and uploads the pledge request information to a pledge block chain for evidence storage. The pledge request includes at least one electronic manifest or an identification of at least one electronic manifest. That is, the pledge requester node 2 sends information of one or more electronic tickets that wish to be collated to the borrower node 4 for evaluation.
As the electronic warehouse bill is generated by adopting various technical means to prevent forgery, and all related information, including the electronic warehouse bill and the associated electronic sales contract, are stored on the certificate storage platform node 5 and can be verified by any pledge blockchain node. Therefore, the lender node 4 can obtain the relevant information for verification and evaluation according to the electronic bill or the identification of the electronic bill in the pledge request. If the assessment passes, the process of signing the pledge contract may be initiated.
Step S500, after the pledge request is authorized, the loan party node 4 interacts with the pledge request party node 2 to obtain a pledge contract with a digital signature and uploads the pledge contract to a pledge block chain for evidence storage.
The process of interacting the mortgage contract with the digital signature and chain-storing the mortgage contract is similar to the process in step S100. Specifically, step S500 includes:
and step S510, the loan party node 4 generates an electronic pledge contract according to the pledge request and the corresponding authorization information and generates a corresponding digital signature. Wherein, the digital signature is obtained by encrypting the electronic pledge contract by the private key of the loan party node 4;
step S520, the loan party node 4 sends the electronic pledge contract, the digital signature and the corresponding public key to the pledge request node 2;
step S530, the pledge request node 2 verifies the electronic pledge contract from the lender node 4 through a public key and a digital signature, and after the verification is passed, the electronic pledge contract is generated to generate a corresponding digital signature through encrypting the electronic pledge contract through a private key of the pledge contract;
step S540, the pledge request node 2 sends the electronic pledge contract, the corresponding digital signature and the public key corresponding to the private key of the pledge request node 2 to the lender node 4;
and S550, the lender node 4 verifies the electronic pledge contract through the received public key and the digital signature, and initiates a block chain transaction to record the abstract of the electronic pledge contract in a pledge block chain after the verification is passed.
Therefore, the certificate file of each link in the whole warehouse receipt pledge flow is stored and certified to a pledge block chain, the inquiry, traceability and verification of the whole flow are realized, the pledge of the warehouse receipt can be realized orderly on the premise that all parties are not trusted, and the behavior of counterfeiting the warehouse receipt is prevented to the maximum extent.
Meanwhile, if the state of the pledge changes, the warehouse slip changes, and the system needs to adapt to the change to perform new evidence storage and warehouse slip updating. Specifically, the system performs the updating and the evidence storage of the electronic warehouse bill according to the following steps:
step S600, after detecting that the physical state information of the goods is updated, the logistics storage node 1 generates an updated electronic manifest according to the updated physical state information and the original electronic manifest.
And S700, the logistics storage node 1 sends the updated electronic warehouse receipt to the pledge request party node 2 and the loan party node 4 and uploads the information of the updated electronic warehouse receipt to the pledge block chain for storage.
Step S800, the pledge node 2 and the lender node 4 interact with the confirmation file with the digital signature and upload the confirmation file to a pledge block chain for evidence storage.
The validation file is similar to the complementary agreement of the electronic mortgage contract. Therefore, the change of the goods can be effectively coped with, and the warehouse slip can be effectively managed.
