Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a schematic view of a main flow of a method for processing a logistics document according to a first embodiment of the present invention, and the method for processing the logistics document may include:
step S101, receiving a plurality of link logistics document comparison instructions, and respectively obtaining service data from block chain link points corresponding to the logistics documents to calculate message abstracts of the block chain node service data.
The block chain is essentially a decentralized database, and is a string of data blocks generated by using a cryptographic method to correlate, and each data block contains information of service data for verifying the validity of the information.
Preferably, the business data is respectively read into the parallel computing engine from the block link points corresponding to the logistics document, so as to respectively obtain the message abstracts of the block link point business data. The parallel computation is implemented by a large data stream processing distributed computation framework in a data parallel and pipeline mode, and is suitable for processing mass data in batches. The message digest is a digital digest, that is, a single Hash function is used to convert the plaintext 'digest' to be encrypted into a string of ciphertext with fixed length, and the string of ciphertext has fixed length.
For example: messages obtained from block link points:
{"keyA":"valueA","keyB":"valueB"}，
then, the abstract of the message is calculated as follows:
6879dd2ff339fac5f1215fa40a7f28899669fa3dd7b13d2778210e0094f58f81
further, fields in the business data are ordered using intelligent contracts. If the calculated hash values are not ordered, they may not be consistent, for example, the two data, i.e., { "keyA": value A "," keyB ": value B" } and { "keyB": value B "," keyA ": value A" }, are identical in value, but are not identical if the calculated hash values are not ordered.
And step S102, acquiring respective local service data based on the service systems respectively corresponding to the plurality of logistics receipts so as to calculate the message abstract of the local service data.
Preferably, the business data obtained from the business system generates a key according to the field name, generates a value according to the contents of the database column, and generates a character string (e.g., { "keyA": value A "," keyB ": value B" }) according to a preset template to calculate the abstract of the character string. Preferably, the strings are generated according to the json format, which is a lightweight data exchange format that is easy for human reading and writing, and also easy for machine parsing and generation.
Step S103, the message abstracts of the local service data are respectively compared with the message abstracts of the corresponding block link node service data, so as to execute comparison of the logistics documents of a plurality of links.
As another embodiment, the logistics documents need to be transferred among the logistics links, a trusted electronic document is needed to be checked in all the links from the warehouse to the transportation and then to the receiving link, before step S101 is executed, corresponding local business data needs to be obtained based on the business system corresponding to the logistics documents in each link, and the local business data is assembled into a message in a preset format through an intelligent contract. And then, storing the message to a block chain node corresponding to the logistics document in the link.
Preferably, the template engine constructed by the intelligent contract generates the uplink message conforming to a certain format. For example, the following json format logistics document message:
{"keyB":"valueB","keyA":"valueA"}
the method comprises the following steps of constructing different template engines according to different logistics documents by using an intelligent contract, wherein one engine corresponds to one service, and the template engine can be reconstructed without restarting the whole service, such as the template structure of a service A: { "keyA": and "" keyB ": are used for filling values into the template according to json data, so that the problem of sorting is avoided, and the filled data is as follows:
{"keyA":"valueA","keyB":"valueB"}。
it is also worth mentioning that the invention can also receive instructions to build new business systems, for example when the local database is not trusted or a new logistics node. And then, acquiring the service data based on the logistics document in which the message abstract of the local service data is consistent with the message abstract of the corresponding block link point service data in comparison. And further, storing the service data into a new service system.
Therefore, the method for processing the logistics document, provided by the invention, has the advantages that a public block chain system is built, both the logistics document and the logistics document are added as a block chain link point, the business data of the logistics document is linked, both the logistics document and the logistics document trust the business data kept on the block chain, and the trust problem when the business system data corresponding to the logistics document is inconsistent can be further solved. In addition, only the abstracts of the data need to be compared, if the abstracts are consistent, the data are not tampered, and if the abstracts are inconsistent, the data on the block chain is taken as the standard, so that the data comparison and the business system data reconstruction corresponding to the logistics document are carried out under the background of hundred million-level concurrence.
That is, the present invention uses the block chain technology, as long as both sides deploy block chain nodes respectively and access the alliance chain, data can be synchronized, only the verification with the block chain system is needed during the verification, and each newly accessed service system can join the block chain node by itself to synchronize service data by itself.

Step S204, the message abstracts of the local service data are respectively compared with the message abstracts of the corresponding block chain link point service data.
In the embodiment, when the consistency of the logistics documents is compared, the local business data and the block link point business data are not directly compared, abstract calculation is used, a big data technology is used for parallel calculation, data of one batch are calculated at one time, and the comparison speed is greatly improved.

Step S207, the inconsistent local business data is tampered, and the comparison results of the logistics documents in the multiple links are different.
In an embodiment, service data with credibility is stored in each blockchain node, and if the local service data is inconsistent with the blockchain node service data, it indicates that the local service data has a problem, and the local service data is not consistent with the related content of the local service data of other links.
It is worth to be noted that in the whole process, the block chain guarantees the safety and the credibility of data, the big data technology performs concurrent computation, and the abstract technology guarantees the comparison performance, so that the anti-tampering, high-performance and rapid construction of the logistics documents are finally realized.

Step S306, acquiring the service data to store the service data into the new service system.
Preferably, each field of the service data in the blockchain node is split and finally inserted into the database of the new service system. For example: traffic data obtained from block chaining points { "mesh point name": "harvest and breed big piece", "address": "certain way", it is right after the check, the new logistics adapter can be inserted into the local database directly.

Because the traditional service system is not supported by a trusted node, when comparing service data of both parties, the whole service message needs to be compared, for example: the method comprises the steps of { "keyA": value A "," keyB ": value B" }, and the two values of value A and value B need to be analyzed, and are compared in the service system of the other party to find out the inconsistent places, and the trust problem exists.
The invention can make each business system compare with the data on the block chain by itself, if the data is consistent with the abstract of the block chain data, the data is credible data, and the comparison does not need to analyze the business message, only needs to compare the abstract, and can quickly reconstruct the database when the data is falsified.
