Fig. 1 is a diagram of a network architecture according to an embodiment of the present application. The network architecture may include a requesting terminal 10a, an interface 10e, and a plurality of servers (specifically, a server 10b, a server 10c, a server 10d, and a server 10d, as shown in fig. 1). The server 10b, the server 10c, the server 10d, and the server 10f may be blockchain nodes in a blockchain network. Taking the example of applying the block chain network to the export tax refunding system, the server 10b may be a server corresponding to a logistics enterprise, the server 10c may be a server corresponding to a manufacturer, the server 10d may be a server corresponding to a purchasing enterprise, and the server 10f may be a server corresponding to a tax office and an export tax office, and the logistics enterprise, the purchasing enterprise and the manufacturer may communicate with the tax office (or the export tax office) through the interface 10e, for example, initiate a data uplink request to the server 10f corresponding to the tax office through the interface 10 e; the request terminal 10a may be an auditing terminal responsible for the export tax refund process, and may send a data auditing request to the server 10f through the interface 10e, for example, to audit related data in the export tax refund business applied by the enterprise, including a certificate of a product purchased by the enterprise (the product belongs to a specified export product type), production data information of the product, a logistics route of the product, and the like, where the server 10f may return an auditing result to the request terminal 10a through the interface 10 e.
The requesting terminal 10a may include a mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable device (e.g., a smart watch, a smart bracelet, etc.), and the like.
Please refer to fig. 2, which is a schematic diagram of a logistics data processing scenario based on a block chain according to an embodiment of the present application. Taking the server 10b (also referred to as a logistics submitting node) corresponding to the logistics enterprise as an example, the uplink process of the logistics data and the auditing process of the logistics data are specifically described. As shown in fig. 2, after a business purchases a product from a manufacturer, the purchased product needs to be transported to a specified destination, such as a warehouse of the business for storing the product, or a product sales site of the business; for the transportation of purchasing the product, this enterprise can cooperate with the logistics enterprise, namely contract the transportation of product for the logistics enterprise, in the in-process of logistics enterprise transportation product, the transportation equipment can be based on the commodity circulation position information of Global Positioning System (GPS) real-time acquisition product, and send the commodity circulation position information who gathers to the server 10b that the logistics enterprise corresponds, server 10b is after receiving the commodity circulation position information, can pack into the commodity circulation data of waiting to link up with logistics position information, logistics company, article product and the time information of gathering this commodity circulation position information. For example, the logistics position 1 for the product d sent by the transportation device received by the server 10b is: longitude 113.986511 and latitude 22.544577, the server 10b may package the name of the logistics enterprise (e.g., "abc carrier"), the name of the product (e.g., "d product"), the logistics location 1 and the time for collecting the logistics location 1 (10: 30: 00/1/2/1/2019) to obtain the logistics data 20a to be linked. The transportation device may collect the logistics position information at intervals (e.g. every half hour), and send the collected logistics position information to the server 10b, where, if the server 10b receives the logistics position 2 for the product d sent by the transportation device, the logistics position 2 is: longitude 80.176511 and latitude 30.544577, the server 10b may package the name of the logistics enterprise (e.g., "abc carrier"), the name of the product (e.g., "d product"), the logistics location 2, and the time for collecting the logistics location 2 (11: 00: 15/1/2/2019), to obtain the logistics data 20d to be linked. Of course, the server 10b may continuously receive the logistics position information for the product d sent by the transportation device until the product d is transported to the destination.
Optionally, in order to enhance the security of the to-be-uplink logistics data (such as the to-be-uplink logistics data 20a and the to-be-uplink logistics data 20d), the to-be-uplink logistics data may be encrypted. Optionally, in order to prevent the logistics data to be uplink 20a from being tampered, the server 10b may generate a digital signature corresponding to the logistics data to be uplink 20 a; in other words, the server 10b may generate a key pair (which may include a private key and a public key) and use the private key to generate a digital signature.
After the server 10b packages the logistics position information into the logistics data to be linked, the logistics data to be linked may be sent to the server 10f corresponding to the tax bureau, that is, after the server 10b packages the logistics data 20a to be linked, the logistics data 20a to be linked may be sent to the server 10 f. After receiving the logistics data 20a to be uplink, the server 10f may perform a signature verification on the logistics data 20a to be uplink, that is, verify whether the logistics data 20a to be uplink is tampered, and if the signature verification fails, the server 10f may determine the logistics data 20a to be uplink as invalid data and delete the invalid data; if the verification passes, it indicates that the to-be-uplink logistics data 20a has not been tampered, and the server 10f may pack the to-be-uplink logistics data 20a into the block 20b, and add the block 20b with the agreed identity to the full-volume business chain 20 c. Of course, after the server 10b packages the to-be-uplink logistics data 20d, the to-be-uplink logistics data 20d may also be sent to the server 10f, and based on the same execution operation, the to-be-uplink logistics data 20d may be packaged into the block 20e, and the block 20e with the consensus is added to the full-service chain 20c, it can be understood that, in the full-service chain 20c, the block 20b is a block before the block 20 e. It should be noted that the full-service chain 20c may be used to store all service data such as enterprise purchase certificates, product production data, product logistics data, and the like, and only the server (i.e., the server 10f) corresponding to the tax bureau has the right to store the full-service chain 20c including all blocks; in other words, the manufacturer, the logistics enterprise, and the purchasing enterprise do not have the authority to store the full business chain 20c, and only store the business chain formed by the blocks corresponding to the uploaded data of the manufacturer, the logistics enterprise, or the purchasing enterprise, that is, the business chain stored by the logistics enterprise only includes the logistics position information uploaded by the logistics enterprise.
After an enterprise (which may be referred to as an audit object) applies for a tax refund service to an export tax office, a terminal device (i.e., the request terminal 10a) corresponding to the export tax office may send a logistics state query request for the audit object to the server 10f, so that the server 10f performs audit on logistics data of the audit object, and returns an audit result. After receiving the logistics state query request sent by the request terminal 10a, the server 10f may determine a product (may also be referred to as a logistics item) associated with the object to be checked based on the logistics state query request, further obtain logistics position information corresponding to the logistics item from the business full-scale chain 20c, and generate a logistics position track 20f corresponding to each logistics item based on the acquisition time corresponding to the logistics position information. The server 10f may perform an audit on the generated logistics position track 20f, for example, determine whether the logistics position track 20f conforms to an article exit route (for example, crosses two countries, etc.), if the logistics position track 20f conforms to the article exit route, the logistics state of the audit object may be determined to be a legal logistics state, that is, the audit is passed, and the server 10f may return a final audit result to the request terminal 10 a.
The request terminal 10a, after receiving the audit result returned by the server 10f, may determine whether to pass the tax refund service applied by the audit target based on the audit result.
Fig. 3 is a schematic flow chart of a logistics data processing method based on a block chain according to an embodiment of the present application. As shown in fig. 3, the method for processing logistics data based on block chains may include:
step S101, obtaining a chain loading request carrying logistics data to be chain loaded associated with an audit object; the logistics data to be linked is determined by the logistics submitting node based on the logistics position information corresponding to the logistics article associated with the auditing object;
specifically, the management node (corresponding to the server 10f in the embodiment corresponding to fig. 2) may obtain an uplink request carrying to-be-uplink logistics data (corresponding to the to-be-uplink logistics data 20a and the to-be-uplink logistics data 20d in the embodiment corresponding to fig. 2) associated with the audit object. The uplink request refers to a request initiated by a logistics enterprise applying for writing logistics data into a full-service chain to a management node through an application platform (corresponding to the interface 10e in the embodiment corresponding to fig. 1); the logistics data to be linked is determined by the logistics submission node (i.e., the server corresponding to the logistics enterprise, corresponding to the server 10b in the embodiment corresponding to fig. 2) based on the logistics location information corresponding to the logistics item associated with the audit object, that is, the logistics submission node can package the logistics location information corresponding to the logistics item associated with the audit object, so as to obtain the logistics data to be linked that satisfies the full-scale business link data structure.
The auditing object may be an enterprise (such as export production enterprise, foreign trade enterprise, etc.) which submits a tax refund application directed to an export tax refund bureau. Taking the audit object as a foreign trade enterprise as an example, the foreign trade enterprise can purchase domestic goods and sell the goods abroad, and the process of uploading the logistics data to be linked on the logistics submitting node is described in detail below. After the foreign trade enterprise purchases the product from the manufacturer, the foreign trade enterprise can sign a purchase contract with the manufacturer and pay a certain fee to the manufacturer, and the foreign trade enterprise can upload the information of the purchase contract, the paid fee and the like as a purchase voucher to the block chain network and request to chain the purchase voucher. After a foreign trade enterprise purchases a product from a manufacturer, if the product is to be sold abroad, the foreign trade enterprise needs to cooperate with a logistics enterprise to transport the product abroad. In the product transportation process, LBS (location Based service) data can be acquired through an external positioning mode (such as GPS) of transportation equipment or a radio communication network of an operator, namely, logistics position information of a product is acquired Based on the GPS or the radio communication network; the transportation equipment can collect the logistics position information once every a period of time, for example, the logistics position information is collected once every half hour, and after the transportation equipment collects the logistics position information of the product, the logistics position information can be sent to a server corresponding to a logistics enterprise, namely, a logistics submission node. The logistics submitting node can package received logistics data such as logistics position information, logistics enterprise information (including names of logistics enterprises and/or numbers of logistics enterprises and the like), product information, acquisition time of the logistics position information and the like, and obtain to-be-linked logistics data.
Optionally, since the capacity of each block in the full block chain is limited, in order to improve the utilization rate of the block capacity, the logistics submission node may convert the logistics data into a Hash value of a fixed length based on a Hash algorithm (which may also be referred to as a Hash algorithm, or a Hash function, or a Hash algorithm), store the association relationship between the Hash value and the logistics data in the database, and send only the Hash value obtained by conversion to the management node as the logistics data to be linked. The hash algorithm may compress data or messages into digests, not only fix the format of the data, but also reduce the amount of the data, and the hash algorithm may include, but is not limited to, SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512. Taking the SHA-256 algorithm as an example, the SHA-256 algorithm can generate a 256-bit hash value for any size of data, and can generate different hash values for different data.
Optionally, in order to prevent the logistics data from being tampered during the process of sending the logistics data to the management node, the logistics submission node may generate a digital signature corresponding to the logistics data. Please refer to fig. 4, which is a schematic diagram of generating to-be-uplink logistics data according to an embodiment of the present application. As shown in fig. 4, after the transportation device 30a (transportation device for transporting products purchased by foreign trade enterprises) acquires the logistics position information through the GPS, the logistics data 30b including the logistics position information may be sent to a server corresponding to the logistics enterprise, that is, a logistics submission node 30c, and the logistics data 30b may include the logistics position information (longitude 113.986511, latitude 22.544577), time information (10: 30:00 in 1/2/1/2019) when the logistics position information is acquired, a logistics enterprise name (abc transportation company), product information (d product), and the like. After the logistics submission node 30c receives the logistics data 30b, if the data amount of the logistics data 30b is too large (for example, greater than the set threshold value of 5 megabytes), the hash algorithm 30f may be used to perform hash operation on the logistics data 30b, convert the logistics data 30b into a hash value 1 with a length of 256 bits, and store the association relationship between the hash value 1 and the logistics data 30b in the database 30 j. The logistics submission node 30c may perform hash operation on the hash value 1 corresponding to the logistics data 30b by using a hash algorithm 30g to obtain a hash value 2, where the hash algorithm 30f and the hash algorithm 30g may be the same hash algorithm or different hash algorithms, which is specifically limited herein.
The logistics submission node 30c may generate a key pair, which may include the public key 30d and the private key 30e, and the logistics submission node 30c may notify the management node of the key pair, i.e., the management node and the logistics submission node may jointly manage the public key 30d and the private key 30e of the key pair. The logistics submission node 30c may encrypt the hash value 2 by using the private key 30e, the encrypted hash value 2 is the digital signature 30h, the hash value 1 carrying the digital signature 30h is determined as the to-be-uplink logistics data 30i, and the to-be-uplink logistics data 30i is sent to the management node.
Optionally, in order to ensure the confidentiality of the logistics data 30b, the logistics submission node 30c may further encrypt the logistics data 30b by using a private key 30e, and if the logistics data 30b is converted into a hash value 1, the hash value 1 may be encrypted by using the private key 30e, in other words, the to-be-uplink logistics data 30i may be a ciphertext carrying the digital signature 30 h.
Step S102, according to a key pair corresponding to the logistics submitting node, performing signature checking on the logistics data to be linked, generating a block of the logistics data to be linked, which passes the signature checking, and adding the block to a service full-scale chain;
specifically, after receiving the logistics data to be linked, the management node can check the labels of the logistics data to be linked according to the key pair corresponding to the logistics submission node, and the specific process of checking the labels is as follows: if the to-be-uplink data is the encrypted logistics data, decrypting the received to-be-uplink data according to a private key corresponding to the logistics submitting node to obtain logistics position information and a digital signature in the to-be-uplink logistics data, decrypting the digital signature according to a public key corresponding to the logistics submitting node to obtain a first hash value corresponding to the digital signature, performing hash operation on the logistics position information based on a hash algorithm to generate a second hash value corresponding to the logistics position information, if the first hash value is detected to be the same as the second hash value, verifying the to-be-uplink logistics data to pass, determining that the uplink request is legal, namely generating a block of the to-be-uplink logistics data, and adding the block which achieves common identification to a full-volume business chain. If the digital signature in the to-be-uplink logistics data received by the management node is not the digital signature of the logistics submission node, that is, the digital signature in the to-be-uplink logistics data is the digital signature generated by using the false private key, the management node directly displays that the decryption fails when decrypting by using the real public key.
Please refer to fig. 5, which is a schematic diagram of an inspection signature of logistics data to be linked according to an embodiment of the present invention. On the premise of the embodiment corresponding to fig. 4, as shown in fig. 5, if the logistics data 30i to be uplink received by the management node 40a is an encrypted ciphertext, the management node 40a may decrypt the logistics data 30i to be uplink using a private key 30e corresponding to the logistics submission node 30c to obtain a hash value 1 and a digital signature 30h in the logistics data 30i to be uplink, and further the management node 40a may decrypt the digital signature 30h using a public key 30d corresponding to the logistics submission node 30c to obtain a hash value 2 (i.e., the first hash value) corresponding to the digital signature 30h, and at the same time, the management node 40a may perform a hash operation on the hash value 1 using a hash algorithm 30g used by the logistics data 30i to be uplink itself to obtain a hash value 3 (i.e., the second hash value). If the hash value 3 obtained by the management node 40c by using the hash algorithm 30g is the same as the hash value 2 obtained by the management node 40c decrypting the digital signature 30h, it indicates that the physical distribution data 30i to be linked passes the signature verification; if the hash value 3 obtained by the management node 40c using the hash algorithm 30g is different from the hash value 2 obtained by the management node 40c decrypting the digital signature 30h, it indicates that the signature verification of the to-be-uplink logistics data 30i is unsuccessful, and the management node 40c may determine the to-be-uplink logistics data 30i as tampered invalid logistics data, and may delete the to-be-uplink logistics data 30 i.
And the management node checks the physical distribution data to be linked, and after the physical distribution data to be linked passes the check, the management node can generate a new block for the physical distribution data to be linked, and the new block is added into the service full-scale chain after the consensus is achieved. It can be understood that the management node may receive, at the same time, to-be-uplink logistics data sent by the multiple logistics submitting nodes, and after the to-be-uplink logistics data all pass the check label, the management node may write, in the same block, the to-be-uplink logistics data received at the same time. Certainly, since the capacity of each block in the full-scale chain of the service is set in advance, after receiving the logistics data to be uplink and passing the verification, the management node may count the capacity information corresponding to the logistics data to be uplink, and if the counted capacity information is greater than the block capacity threshold (i.e., the set maximum capacity of the block) in the full-scale chain of the service, split the logistics data to be uplink based on the block capacity threshold to obtain at least two sub data to be uplink, generate a block corresponding to each sub data to be uplink, and add the plurality of blocks into the full-scale chain of the service after the blocks achieve the common identification. The logistics data to be linked may refer to actually acquired logistics data such as logistics position information, logistics enterprise information, logistics position acquisition time, product information and the like, or may refer to a hash value with a fixed length after conversion of a logistics submission node.
Please refer to fig. 6, which is a schematic diagram of a generation block according to an embodiment of the present application. Taking the physical distribution data to be linked received by the management node as an example of actual physical distribution data, as shown in fig. 6, if the management node 50d receives the physical distribution data 50a sent by the physical distribution submitting node 1, the physical distribution data 50b sent by the physical distribution submitting node 2, and the physical distribution data 50c sent by the physical distribution submitting node 3 at the same time, the management node 50d may perform a check-out on the physical distribution data 50a, the physical distribution data 50b, and the physical distribution data 50c, and after the check-out is passed, may count the total capacity information of the physical distribution data 50a, the physical distribution data 50b, and the physical distribution data 50c, if the total capacity information obtained by the count-out is smaller than the block capacity threshold value in the service full-volume chain 50f, then may pack the physical distribution data 50a, the physical distribution data 50b, and the physical distribution data 50c into the same block 50e (as shown in fig. 6), where the physical distribution data 1 stored in the block 50, the stored logistics data 2 is logistics data 50b uploaded by the logistics submitting node 2, the stored logistics data 3 is logistics data 50c uploaded by the logistics submitting node 3, and the newly generated block 50e with consensus can be added to the full-scale business chain 50 f.
If the total volume information obtained by statistics is greater than the block volume threshold in the full-volume service chain 50h, the logistics data 50a, the logistics data 50b, and the logistics data 50c may be packed and written into a plurality of blocks, for example, the logistics data 50a, the logistics data 50b, and the logistics data 50c may be written into different blocks, that is, the management node 50d may generate three different blocks, and after a consensus is reached, the newly generated three blocks may be added to the full-volume service chain 50 f.
Step S103, when a logistics state query request aiming at the audit object and sent by a request terminal is received, acquiring the logistics position information associated with the audit object from the block of the business full-scale chain according to the logistics state query request, and generating a logistics position track corresponding to the audit object based on the logistics position information;
specifically, the audit object may submit a service processing request on the application platform, for example, submit an export tax refund application in the export tax refund platform, after the audit object submits the service processing request, the terminal device (i.e., the request terminal) to which the application platform belongs may send a logistics state query request for the audit object to the management node, the management node may determine, based on the received logistics state query request, a logistics item (i.e., product information) associated with the audit object, may further obtain, from the business full-scale chain, all blocks associated with the logistics item, determine, from the blocks, logistics position information associated with the logistics item, and based on the obtained logistics position information, may generate a logistics position trajectory corresponding to the audit object. It is understood that the logistics items associated with the audit object may include different products transported in different batches, and the same product in the same batch has the same logistics route (multiple unit location information may be collected in the logistics route), that is, the same logistics location track may be generated; for different batches of the same product or different batches of different products, different logistics routes are provided, that is, different logistics position tracks can be generated, so that the logistics position track corresponding to the audit object can include a plurality of logistics position tracks.
The specific process of generating the logistics position track can comprise the following steps: respectively obtaining time information carried by the unit position information, sequencing the unit position information based on the time information to obtain a sequencing result, performing point tracing on the unit position information according to a time sequencing sequence in the sequencing result, and further generating a logistics position track corresponding to an audit object. In other words, all the unit position information corresponding to the same batch of the same product can be acquired, and the tracing can be performed based on the unit position information to generate the logistics position track corresponding to the same batch of the same product.
Optionally, when the management node receives a logistics state query request for the audit object sent by the request terminal, the management node may first obtain article attribute information corresponding to the logistics article associated with the audit object, and if the article attribute information corresponding to the logistics article belongs to an export goods type specified by the country, execute the subsequent steps; otherwise, the management node may directly return the result that the audit is not passed to the requesting terminal.
And step S104, auditing the logistics position track based on the target track range associated with the legal logistics state, generating an auditing result corresponding to the auditing object, and sending the auditing result to the request terminal.
Specifically, the management node may audit the generated logistics position trajectory based on a target trajectory range associated with a legal logistics state, where if the logistics article is a product exported to the united states, the target trajectory range may be within a range within the country and the united states, and by detecting whether the logistics position trajectory is transported from the country to the united states, if the logistics position trajectory is displayed as starting from the country and destined for the united states, it may be determined that the logistics position trajectory belongs to the target trajectory range, and then the audit object may be determined to be a qualified logistics state, and then the management node generates an audit result corresponding to the audit object based on the qualified logistics state and the logistics position trajectory, and sends the audit result to the request terminal, and the audit result returned to the request terminal may be: and the logistics data is approved. If the logistics position trajectory does not belong to the target trajectory range, if the logistics position trajectories all belong to China, the audit object can be determined to be in an unqualified logistics state, an audit result is generated based on the unqualified logistics state and the logistics position trajectory, the audit result is sent to the request terminal, and the audit result returned to the request terminal can be: and the logistics data audit is not passed.
Please refer to fig. 7, which is a schematic view of a scenario for querying a logistics status according to an embodiment of the present application. As shown in fig. 7, the request terminal may send a logistics state query request for the audit object to the management node, where the logistics state query request specifically includes: after the management node receives a logistics state query request sent by a request terminal, it can be determined that the audit object is an enterprise a and the logistics articles associated with the enterprise a are products b and c from the logistics state query request; the management node may obtain a block set 60b associated with the product b and a block set 60c associated with the product c from the traffic full-scale chain 60a, read all the logistics position information corresponding to the product b from the block set 60b, and perform dotting on the logistics position information of the product b based on the time sequence carried by all the logistics position information of the product b to generate a logistics position track 60d corresponding to the product b; reading all the logistics position information corresponding to the product c from the block set 60c, and based on the time sequence carried by all the logistics position information of the product c, dotting the logistics position information of the product c to generate a logistics position track 60e corresponding to the product c. The management node may determine the logistics position track 60d and the logistics position track 60e as logistics position tracks corresponding to the enterprise a, and when the logistics position track 60d and the logistics position track 60e both belong to a target track range (that is, meet a logistics route range corresponding to the export goods), may determine the enterprise a as a qualified logistics state, that is, the logistics data of the enterprise a is approved, and return an approval result of the approved logistics data to the request terminal.
