The "logistics information" described in the embodiments provided by the present specification may be generated by the e-commerce platform system according to the user's e-commerce order, and provided by the e-commerce seller to the logistics delivery network, or may be any logistics express delivery The company or individual user of the service is directly provided to the logistics delivery network. The logistics information usually includes the name, telephone number, and address information of the receiving user and/or the sending user, and in particular, the name and telephone information are the most private. In order to ensure the privacy of the logistics information, in all the embodiments provided in the present specification, the logistics information is transmitted in an encrypted state in the logistics information system based on the blockchain establishment.

The existing logistics information system, the delivery outlet is usually the outlet near the delivery place of the specific order in the logistics information system; the distribution outlet is the outlet designated by the logistics information system for the specific delivery address, and the distribution outlet can usually be conveniently distributed. It is the outlet near the user's delivery address. Of course, the shipping outlets and distribution outlets described in the embodiments provided in the present specification are not limited to the above-mentioned general regulations, and the specific logistics information system may set corresponding shipping outlets and distribution outlets according to the rules of the own system. In order to further ensure the privacy of the logistics information in the delivery process, in the embodiment provided by the present specification, the shipping outlet first determines a specific delivery network according to the user receiving address in the logistics information, and then uses the public key associated with the delivery network. The key encrypts the above-mentioned logistics information to obtain encrypted logistics information; the encrypted logistics information can only be decrypted by the key associated with the private key of the above-mentioned distribution network, and the privacy of the private key ensures that the encrypted logistics information can only be It is decrypted by the above-mentioned distribution network, thereby preventing other nodes in the same blockchain except the above-mentioned distribution network from being informed of the logistics information, and further enhancing the strength of protecting the user information. There are many corresponding encryption algorithms, such as an asymmetric encryption algorithm based on ECDSA or RSA. In the embodiments provided in this specification, the encryption method can be specifically set according to requirements.

The "blockchain" described in the embodiments provided by the present specification may specifically refer to a P2P network system having a distributed data storage structure achieved by a consensus mechanism, and the data distribution in the blockchain is connected in time. Within the "block", the latter block contains the data summary of the previous block, and all or part of it is achieved according to the specific consensus mechanism (such as POW, POS, DPOS or PBFT). A full backup of the node's data. It is well known to those skilled in the art that since the blockchain system operates under the corresponding consensus mechanism, the data that has been included in the blockchain distributed ledger is difficult to be tampered with by any node. For example, a blockchain using the Pow consensus requires at least It is possible for a 51% computing attack on the entire network to tamper with existing data. Therefore, the blockchain system has the characteristics of ensuring data security and anti-attack tampering compared with other centralized database systems. Therefore, in the embodiment provided by the present specification, the encrypted logistics information included in the distributed ledger of the blockchain is difficult to be attacked or tampered with, thereby ensuring that the logistics distribution network can accurately and accurately encrypt the logistics. The information is decrypted and delivered to the user's shipping address, without affecting the efficiency of logistics delivery.

In summary, the blockchain-based logistics information transmission method shown in FIG. 1 realizes the protection of user logistics information in the process of logistics information transmission involving the logistics information system, and can effectively prevent the transit point of the logistics process. Possible risk of user information disclosure.

From the point of view of function realization, for different logistics orders, the same logistics outlet can be used as a logistics delivery network or as a logistics distribution network; for the same logistics transmission order, the same outlet can be used for logistics delivery outlets or logistics. Distribution outlets are not limited in this specification. In the embodiments described herein, the logistics shipping network, and the logistics distribution network can be joined as the blockchain by following the installation of the corresponding node protocol and the running node protocol program. The embodiments provided in this specification can be run on any computing and storage device, such as a mobile phone, tablet, PC (Personal Computer), notebook, server, etc.; it can also be run by two or two The logical nodes of the above devices implement the functions in the embodiments of the present specification.

Further, in order to ensure that the logistics information stored on the blockchain is not uploaded by any other node posing as a logistics shipping network, the above-mentioned distributed logistics information of the encrypted logistics information to the blockchain further includes: The encrypted logistics information is digitally signed to obtain an encrypted logistics information signature; the shipping network point sends the encrypted logistics information and the encrypted logistics information signature to a distributed ledger of the blockchain; correspondingly, the foregoing use and Decrypting the encrypted log information to obtain the logistics information by the key related to the private key of the delivery network, further comprising: the distribution network checking the signature of the encrypted logistics information; after the verification is passed, the The distribution network decrypts the encrypted logistics information using a key associated with the private key of the delivery network to obtain the logistics information.

Those skilled in the art should know that the node with the accounting function on the blockchain, such as the miner node on the public chain established by the POW or POS consensus mechanism, needs to verify the data records that can be included in the blockchain distributed ledger. The verification process may include the verification of the digital signature of the data to be included, the verification process is to prevent the data from being tampered with or the information is forged by other participants, and the miner node that obtains the accounting right after the verification is passed includes the data to be included. In the block of the blockchain. In the above embodiment shown in the present specification, in order to prevent other nodes from forging or changing the logistics information, the distribution network points again to verify the signature of the encrypted logistics information, and after the verification is passed, the distribution network uses and distributes the distribution network. The private key related key decrypts the encrypted logistics information to obtain logistics information.

The embodiment of the present specification does not specifically define the algorithm for the digital signature and the verification algorithm, the delivery of the logistics information system, and the public key-private key pair of the distribution network, and may be completed by using an elliptic curve algorithm, an RSA algorithm, etc., and the related hash algorithm. Can be done with MD5, SHA256, etc.

The above-mentioned shipping network digitally signs the encrypted logistics information to ensure the reliability of the encrypted logistics information source, that is, to ensure that the encrypted information is accurately derived from the above-mentioned shipping network, and any other node in the same blockchain cannot be The encrypted logistics information is falsified or pretending to be the outlet of the shipping information for the release of the encrypted information, and finally ensures that the logistics information (including the user's receiving address information) is accurate and tamper-free, ensuring the correct execution of the decryption process and the accurate delivery of the delivery behavior. Da.

As shown in FIG. 3, the key associated with the public key of the delivery network may be a public key of the delivery network. Correspondingly, the key associated with the private key of the delivery network is the distribution network. Private key. Figure 3 (a) illustrates the process of the receiving network using the public key of the distribution network to encrypt the logistics information, digitally signing the encrypted logistics information, and then uploading the encrypted logistics information and the encrypted logistics information signature to the blockchain; (b) It indicates that the distribution network obtains the encrypted logistics information and the encrypted logistics information signature from the distributed ledger of the blockchain, and performs the digital signature verification of the encrypted logistics information signature. After the verification is passed, the private key pair of the distribution network is used for encryption. The process of decrypting logistics information to obtain logistics information.

The process of encrypting the logistics information to obtain the ciphertext may also be implemented by means of a mutually agreed symmetric key. For example, as shown in FIG. 4, encrypting the plaintext of the logistic information as a receiving network can use the ECDH to exchange keys. It is well known to those skilled in the art that in the blockchain system using the same elliptic curve algorithm (ie, selecting the same straight line or base point) to obtain the public key-private key pair associated with different network identity, the private key AS of the network A and the secondary B are The product of the public key BP is equal to the product of the public key AP of the site A and the private key BS of the site B.

Namely: AS·BP=AP·BS,

In the embodiment described in the present specification: the public key of the shipping outlet FP·the private key of the delivery network PS=the private key of the shipping outlet FS·the public key of the delivery outlet PP

Therefore, as shown in FIG. 4(a), the shipping network can encrypt the plaintext of the logistics information by using the key obtained by multiplying the public key PP of the corresponding distribution network with its own private key FS to obtain encrypted logistics information; similarly, In order to ensure that the encrypted logistics information is not falsified and forged, the shipping network digitally signs the encrypted logistics information, and signs the encrypted logistics information, encrypts the logistics information and the private key used to encrypt the above-mentioned logistics information. The public key FP corresponding to the FS and the public key PP of the distribution network used for encryption are uploaded to the logistics information system blockchain database cache, waiting for the accountant of the blockchain, such as the pre-selected in the alliance chain. The node of the accounting authority records the above information into the block of the above blockchain.

After the encrypted logistics information signature, the encrypted logistics information, the public key FP, and the public key PP are included in the blockchain by the accounting node of the blockchain, the distribution network may obtain the above information from the blockchain, as shown in the figure. 4(b), correspondingly, the distribution network first performs digital signature verification on the encrypted logistics information, and after the verification is passed, the private key PS corresponding to the public key PP of the distribution network is used and the obtained public The key obtained by multiplying the key FP decrypts the encrypted logistics information to obtain specific logistics information. The other encrypted node cannot decrypt the encrypted logistics information because the private key PS of the delivery network cannot be known.

It is worth noting that since the same organization or logistics network can have multiple sets of public-private key pairs in a blockchain, the above-mentioned public key FP and private key FS used for encrypting the logistics information are not necessarily related to the above digital signature process and The private key and the public key used in the verification are the same, but this does not affect the implementation of the technical solution, but reduces the possibility of being attacked by increasing the complexity of the system.

More preferably, in order to reduce the validation time of the data on the chain, increase the transaction throughput, and meet the security and performance requirements, the cluster chain architecture can usually be used to construct the blockchain. The consensus process of the alliance chain is controlled by pre-selected nodes. When a node on the network exceeds a set proportion (such as 2/3) to confirm a block, the transaction or data recorded by the block will be confirmed by the whole network. The alliance chain can determine the degree of openness to the public according to the application scenario, and the accessibility mechanism can be given access to the alliance chain. For example, in this embodiment, a large and medium-sized logistics collection and distribution network and the like with a high degree of credibility can be The pre-selected nodes participate in accounting, and each small-scale logistics distribution point or other affiliated outlets can be a general node with access to the alliance chain, and the like.

The alliance chain usually uses equity proof or consensus algorithms such as PBFT and RAFT. Figure 2 illustrates the consensus-consistent process of the simplified PBFT algorithm, where C is the client, N ₀ - N ₃ represent the service node, and in particular, N _{0 is the} master node and N ₃ is the fault node. The PBFT system usually assumes that the number of faulty nodes is m and the number of service nodes is 3m+1. In simple terms, the entire communication process is as follows:

1) The client sends a request to the master node to invoke the service operation;

2) After the master node receives the request, initiate a three-phase protocol to broadcast a request to each slave node;

[2.1] Sequence number allocation stage (also known as pre-prepare stage), the master node assigns a sequence number n to the request, broadcasts the sequence number assignment message and the client's request message m, and constructs a PRE-PREPARE message to each slave node;

[2.2] Interaction phase (also known as prepare phase), receiving a PRE-PREPARE message from a node, and broadcasting a PRE-PREPARE message to other server nodes;

[2.3] Sequence number confirmation phase (also known as commit phase), after each node verifies the request and order in the view, it broadcasts a COMMIT message, executes the received client's request and gives the client a corresponding response.

3) The client waits for a response from a different node. If there are m+1 responses the same, the response is the result of the consensus.

Like all state machine replica replication technologies, PBFT proposes two qualifications for each replica node:

1) All nodes must be deterministic. That is to say, in the case where the given state and parameters are the same, the results of the operation execution must be the same;

2) All nodes must be executed from the same state.

Under these two qualifications, even if the failed replica node exists, the PBFT algorithm agrees on the total order of request execution for all non-failed replica nodes, thus ensuring security.

According to the consensus communication process shown in FIG. 2, a block is generated to generate a block, and finally a chain is formed. As a preferred implementation manner provided by the present specification, the PBFT algorithm is high in efficiency and can meet the requirements of high-frequency transaction volume, for example, frequent online shopping order logistics distribution information in this embodiment, A large number of orders for express logistics information; and the consensus delay is very low, basically meeting the requirements of real-time processing; trusted nodes as pre-selected accounting nodes, taking into account security and stability; in addition, the PBFT algorithm does not consume Excessive computer computing resources do not necessarily require token circulation, so they have good usability.

The above various embodiments describe a technical solution for preventing tampering, counterfeiting and leaking logistics information of a logistics transit point in the process of transporting logistics information, but for the distribution network and the delivery staff, since the logistics information has been decrypted, the receiving party user and / or the logistics information of the privacy information of the shipper user is presented in clear text. The delivery personnel can leak the logistics information through copying, photographing, etc.; and the distributed logistics information will usually be printed on the express parcel during delivery. After the receiving party receives the package unpacking, it often dumps the express information in the trash can, which is also a hidden danger of information leakage.

In order to solve the above-mentioned possible user information leakage, the embodiment of the present specification provides that the logistics information further includes the encoded user information, and the encoded user information refers to encoding and protecting the user information according to a specific encoding processing rule, and after encoding User information will no longer actually display or no longer display relevant user information, especially user information related to privacy, such as name and phone number. It is worth noting that due to the development of technology, the instant contact method is not limited to a fixed telephone, a mobile phone, a software call APP, a social software APP, etc., and therefore, in the embodiment shown in the present specification, the user log information is not limited. The type of information protected by the code.

Specifically, the above code protection processing process may be: mapping the user phone number in the logistics information according to a preset rule to obtain a virtual phone number, or hiding several digits in the phone number, and displaying only other The remaining digits, or the name in the user information is hidden, only the partial name of the user is displayed, and the encoding rule method for processing the user information into the encoded user information is not limited in this specification. . For example, the user phone map is encoded into a short number by the following rules:

Map the phone number 13012345678 to the 4-digit shipping outlet number + date + 6-digit coded number.

Thus, even in the logistics information system, the real-time logistics information is known by the distribution network (including the distribution end), and the real telephone number of the user cannot be known. The method of encoding the user logistics information to obtain the encoded user information may be performed by a shipping network of the logistics information system, or may be executed by the e-commerce platform system when generating an e-commerce order, or may be provided by a third party. The platform for information coding protection is not limited in this specification. Each coding party can encode specific user information according to the platform settings or the user's own choice to complete the protection.

The e-commerce platform system described in the embodiments provided by the present specification is a network platform for the buyer user and the seller user to realize the transaction. If the two parties reach a consensus, the buyer user creates an order in the interface provided by the e-commerce platform system, and the e-commerce platform system according to the The cargo information generates a corresponding transaction order, and the corresponding buyer or receiver user information in the order usually includes the user's name, instant contact information (such as a phone number), or the recipient address, and the user's name and instant contact information. It is extremely private information and is easily sold by unscrupulous people (such as seller users of e-commerce platforms) in modern society. Therefore, in the embodiments provided in this specification, the e-commerce platform will be the buyer in the transaction order or The receiver user information is encoded and protected, and the encoded user information will no longer actually display or completely display related user information, especially user information related to privacy, such as name and phone number. Therefore, the logistics information that the seller of the e-commerce platform knows and the logistics information that is handed to the logistics delivery network is the encoded user information, so the embodiment isolates the seller of the e-commerce platform and the entire logistics information system (including the delivery) All possible user information leakage risks, such as outlets, transit outlets, and distribution outlets, have good practical results.

Correspondingly, when the distribution is based on the logistics information, the distribution network (including the delivery end) needs to call the user information decoding program, decode the encoded user information, and contact the user for distribution.

It can be seen from the above analysis that the above-mentioned user information decoding program can be provided by the logistics information system, or can be provided by the e-commerce platform system, or can be provided by a third party to provide a user information coding protection platform, which is not limited in this specification. The distribution network (including the delivery end) decodes the contact information by calling the preset user information, and decodes the encoded user information into actual user information, and contacts the user for distribution.

The specific way of contacting the user to perform the above-mentioned distribution is called, for example, the distribution end of the logistics information system (which may be a delivery person or a delivery robot, a delivery drone, etc.) to call the user information decoding contact program of the e-commerce platform, the program background Restore the virtual phone number in the encoded user information to the actual phone number, and call the phone number to contact the delivery; or restore the virtual phone number in the encoded user information to the actual phone number, and send the address to the user After the nearby express warehouse is delivered, send the SMS message containing the box number and password of the express storage cabinet to the telephone number; or restore the hidden other voice communication method in the encoded user information, and use the communication method with The user performs network voice communication or text communication; or a combination of the above various methods; and the like.

It should be noted that in the embodiment provided by the present specification, although the user information decoding program can decode the encoded user information to obtain actual user information, the actual user information should not be in the foreground of the decoding program. The display or the delivery end (which may be a delivery person or a delivery robot, a delivery drone, etc.) knows that the foreground contact window of the decoding program should not display the actual user information or still display the encoded user information, thereby ensuring that the user information is The delivery phase cannot be known by the delivery side, preventing user information that may be generated at the delivery end from leaking.

More preferably, the e-commerce platform system can also be used as a node of the block network of the distribution network system and the delivery network of the above-mentioned logistics information system, so as to conveniently complete the logistics delivery order operation directly in the above blockchain, or in real time. Follow up and share information published by various logistics outlets (such as logistics tracking status information), etc.

The above multiple embodiments provided by the present specification specifically describe a logistics information transmission method for preventing leakage of logistics information from the interaction between the delivery network of the logistics information system based on the blockchain and the two ends of the distribution network, and the following description will respectively The embodiment of the logistics information transmission method is briefly described at the delivery network end and the distribution network end.

It prevents the leakage of user information that may occur during the distribution process of the logistics distribution network and after the delivery of the express logistics package.

More preferably, the encoded user information is generated by the e-commerce platform system for encoding and processing the user information, and the private information in the logistics information is made when the e-commerce platform system delivers the user information to the logistics delivery network. The encoding process prevents the entire logistics information system from knowing the user's private information and prevents user information from being leaked during the entire logistics process.

Through the verification of the signature of the encrypted logistics information, it is further ensured that the encrypted logistics information will not be issued by any other node posing as a shipping outlet to ensure the accuracy of the logistics information.

Due to the characteristics of the blockchain where the logistics information system is located, there are many specific encryption methods, such as a symmetric key, a salt-encrypted encryption, and an agreed asymmetric encryption method. According to the specific encryption method, the distribution network performs the corresponding Decryption method.

Optionally, the key related to the private key of the delivery network is: a private key of the delivery network.
