Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The system aims to solve the problems that transportation and sales sensor nodes which provide energy by using a rechargeable battery are limited in storage, processing and transmission capacity, the structure is complex, and logistics data and article identification collected in the links of article production, transportation, sales and the like can be artificially tampered and damaged. The disclosure provides an information verification method based on a block chain, a server and an article node. The following detailed description is made with reference to the accompanying drawings which respectively illustrate embodiments provided by the present disclosure.
Fig. 1 shows a flowchart of a block chain-based information verification method on a server side according to an embodiment of the present disclosure.
Referring to fig. 1, the method for verifying information based on a blockchain provided in this embodiment includes the following steps.
Step S101, receiving a service request sent by a service platform to the server.
Step S102, the article identification in the service request is obtained.
Wherein the nodes in the blockchain include servers and item nodes. The server is a server corresponding to the intelligent factory node. Referring to fig. 2, when an article is produced by the intelligent factory node, a unique article identifier is marked on the article and is stored in the intelligent chip for internal calculation and storage of the article. The article identification is recorded in the server as a unique authentication code.
In step S101 and step S102, the server in the blockchain corresponds to the intelligent plant node and is also a background server of the service platform. When the user uses the article, the article node sends a service request to the service platform, and the service platform forwards the service request to the server. The server verifies the data and the user can use the article after the verification is passed.
The server in the blockchain of the embodiments of the present disclosure mainly takes on two recording roles: the article node is registered in a network; and recording the second information generated by the article identification and the logistics data. Referring to fig. 2, there are two different types of chunks in a server in a blockchain, namely authentication chunks and data check chunks. And the servers in all the block chains jointly form a block chain, and simultaneously form a peer-to-peer network of the block chain, and the records in the block chain blocks are checked.
The following briefly describes the network access registration process of the article node:
1, when an item is first connected to a network of blockchains at production, it is necessary to complete identity registration at the blockchain. The system generates a public and private key address for each article through an asymmetric encryption algorithm (RSA, elliptic curve and other algorithms), and the private key information comprises the article identification of the article. Each individual device retains its own private key and records the corresponding public key and other information onto a dedicated authentication block of the blockchain.
When logistics data of new storage nodes (the storage nodes can be intelligent factory nodes, logistics transportation nodes and distribution block servers) with changed commodity life cycles are accessed to the network later, the storage nodes are required to broadcast (public keys and other information) information of related commodities, the commodity nodes which are already on the network are audited, the new nodes which pass the audit (more than 51% of nodes agree) are allowed to be accessed to the network, and the related information is recorded in a newly generated authentication block. And all the article nodes recorded on the authentication block can be subjected to data verification.
And 3, when the article nodes (single article damage and repair or unqualified destruction) or the storage nodes (point of sale withdrawal, logistics cooperation withdrawal and factory reclosing) exit the network in batches, broadcasting needs to be sent, and the equipment is declared to exit the network. On the newly created authentication block, the relevant information of the device will not be recorded any more. The last authentication block on the block chain is required to retain all the relevant information of the effective equipment, the previous authentication block is only used for forming a chain structure and has no verification significance, the identification of the article in the sold article is not influenced, once the storage node exits the network, the information recorded by the storage node can not exist in the block chain network, and the generation of pirated articles caused by the accidental outflow of the equipment is prevented.
In a preferred embodiment, the articles are intelligent bricks.
And step S103, acquiring pre-stored logistics data corresponding to the article identification.
And step S104, calculating first information according to the article identification and the logistics data.
Step S105, a pre-stored block number corresponding to the article identifier is obtained, and second information corresponding to the block number is obtained in the block chain.
And S106, determining whether the article identification and/or the logistics data are tampered or not according to the first information and the second information.
Before the step S103 to the step S106, the article node hashes the logistics data (data collected during the logistics links such as production, sales, and transportation of the article) and the article identifier by using a Hash algorithm (for example, SHA-256 algorithm), so as to form second information of the data. I.e. a short characteristic string of fixed byte length in a specific time. Then, the article node encapsulates the signature information and the second information (Hash value), and then performs digital signature using its own private key address. The broadcast is sent into a block chain. After receiving the broadcast information, other network nodes in the block chain firstly determine the validity of the equipment according to the equipment registration information recorded on the building block authentication block. The signature of the data is checked by using the public key address of the equipment recorded in the building block authentication block, and only after the data passes the check and verification, the true and valid data uploaded by the equipment is confirmed. And storing the public key and the Hash identification of the corresponding article node to the block chain to form an effective data identification record and finish the block chain record. And after the steps are completed, the article node sends the logistics data, the article identification and the corresponding block number to the server to finish data storage.
In step S103 to step S106, when the user uses an article, the article node sends a service request to the server in the block chain through the service platform, and the server obtains an article identifier in the service request and performs verification in the data verification block in the server. The server acquires the pre-stored logistics data corresponding to the article identifier, and recalculates the Hash value of the article identifier and the logistics data, namely recalculates the first information. And the server locally stores the block number corresponding to the article identifier, searches the corresponding block in the block chain according to the block number and acquires second information in the block. The server determines whether the article identification and/or the logistics data are tampered or not according to the first information and the second information.
In the embodiment of the disclosure, the block chain is applied to the data acquisition process in logistics links such as production, transportation and article sale, so that the articles can be prevented from being interfered by improper persons in the production, transportation and sale processes, and the logistics data and the article identification are prevented from being falsified by counterfeit pirates, factories and internal management supervisors. And the block chain is used for storing and recording data, the storage, processing and transmission capabilities are not limited, and the architecture is simple.
In some embodiments, the determining whether the item identification and/or the logistics data is tampered according to the first information and the second information (i.e. step S106) includes: in response to determining that the first information is consistent with the second information, determining that neither the item identifier nor the logistics data has been tampered with; in response to determining that the first information is inconsistent with the second information, it is determined that the item identification and/or the item data is tampered with.
In the above step, the server compares the calculated first information with the second information found in the blockchain. And if the first information is consistent with the second information, determining that the article identification and the logistics data are not tampered, wherein the logistics data are acquired through links such as production, transportation and sale in a legal way, and the article identification is legal and effective. If the first information is inconsistent with the second information, it is determined that the item identification and/or the item data has been tampered with.
In some embodiments, the calculating the first information according to the article identification and the logistics data (i.e., step S104) includes: converting the article identifier into third information in a character format; and calculating the first information according to the third information and the logistics data.
In the above step, the first information is a short characteristic character string with a fixed byte length in a specific time. The item identifier is generally a numeric code, for example 001, the item identifier is converted into third information in a character format, and the first information is calculated based on the third information and the logistics data, such as a hash value calculated by the SHA-256 algorithm.
Fig. 3 shows another flowchart of a block chain-based information verification method on the server side according to an embodiment of the present disclosure.
In some embodiments, the service request further includes an authentication parameter, and after receiving the service request sent by the service platform to the server, referring to fig. 3, the method further includes:
step S201, obtain the authentication parameter in the service request.
Step S202, in response to the authentication of the authentication parameters according to the authentication information of the goods pre-stored by the server and the fact that the goods identification and the logistics data are not tampered, a message allowing the use of the service is sent to the service platform.
In step S201-step S202, the authentication block includes authentication information such as an authentication code of the article, a production place, a production time, copyright authorization information, a physical address of the physical node, and a network access time in addition to the article identifier. And after receiving the service request sent by the service platform, the server acquires the authentication parameters in the service request. If the authentication parameters are authenticated by the authentication block in the server according to the authentication codes of the locally stored articles, the authentication information such as the production place, the production time, the copyright authorization information, the physical address of the physical node, the network access time and the like, and the article identification and the logistics data are determined not to be tampered, the authentication block sends a message allowing the use of the service to the service platform.
In the embodiment of the disclosure, the service platform is automatically networked when copyright authentication traceability, counterfeit screening, networking fight and play guidance functions are performed on the articles, for example, the building blocks, authentication is performed through the authentication block in the server, and the service function in the articles can be used only when the authentication is passed.

In step S304, the block number of the new block is obtained.
Step S305, the logistics data, the block number and the article identification are sent to the server node in the block chain, so that the server node can be stored locally.
In steps S301 to S305, the article is grounded, and the logistics data (data collected in logistics links such as production, sales, and transportation of articles) of the article node and the article identifier of the article node are obtained. The logistics data and the article identification are hashed by a Hash algorithm (such as SHA-256 algorithm) to form second information of the data. I.e. a short characteristic string of fixed byte length in a specific time. Then, the article node encapsulates the signature information and the second information (Hash value), and then performs digital signature using its own private key address. The broadcast is sent into a block chain. After receiving the broadcast information, other network nodes in the block chain firstly determine the validity of the equipment according to the equipment registration information recorded on the building block authentication block. The signature of the data is checked by using the public key address of the equipment recorded in the building block authentication block, and only after the data passes the check and verification, the true and valid data uploaded by the equipment is confirmed. And storing the public key and the Hash identification of the corresponding article node to the block chain to form an effective data identification record, generating a new block comprising the second information, and finishing the block chain record. And after the steps are completed, the article node sends the logistics data, the article identification and the corresponding block number to the server to finish data storage.
In the embodiment of the disclosure, the block chain is applied to the data acquisition process in logistics links such as production, transportation and article sale, so that the articles can be prevented from being interfered by improper persons in the production, transportation and sale processes, and the logistics data and the article identification are prevented from being falsified by counterfeit pirates, factories and internal management supervisors.

In the above step, the second information is a short characteristic character string with a fixed byte length in a specific time. The item identifier is generally a numeric code, for example 001, the item identifier is converted into fourth information in a character format, and second information, such as a hash value calculated by the SHA-256 algorithm, is calculated based on the fourth information and the logistics data. Because the logistics data is collected in real time, the second information is updated as the logistics data is updated.
