Detailed Description

Before discussing exemplary embodiments in greater detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations as a sequential process, many of the operations can be performed in parallel, concurrently, or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, subprograms, and the like.

It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of example embodiments. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, and merely illustrates the basic structure of the present invention in a schematic manner, and therefore it shows only the constitution related to the present invention.

For ease of understanding, the terms appearing in the following examples are explained as follows:

block chain technique: the distributed data processing system is a brand new distributed infrastructure and computing paradigm for verifying and storing data by using a block chain type data structure, generating and updating data by using a distributed node consensus algorithm, ensuring the safety of data transmission and access by using a cryptographic mode, and programming and operating data by using an intelligent contract consisting of automatic script codes. In essence, it is a shared database, and the data or information stored in it has the characteristics of being unforgeable, having trace in the whole course, being traceable, being publicly transparent, being maintained collectively, and the like. Based on the characteristics, the block chain technology lays a solid trust foundation, creates a reliable cooperation consensus mechanism and has wide application prospect.

API: application programming interface (api) is a description of the way a single computer program can interact with another program (class, procedure, function, structure, or constant). It is typically included in the description of any Internet protocol, software framework or standard calls to operating system functions. It is usually implemented by a separate software library or operating system service. Developers typically use APIs to write various applications. An API defines the functionality provided by a program (module, library) and allows abstraction from the implementation of that functionality. The software components interact with each other through an API. In this case, the components typically form a hierarchy: the high-level components use the APIs of the low-level components, which in turn use the APIs of even lower-level components. Applications that provide web services typically provide an API for the HTTP protocol.

And (3) SDK: software development kit, a collection of development tools used by software engineers to create application software for a particular software package, software framework, hardware platform, operating system, etc. Thus, an SDK software development tool includes a collection of related documents, paradigms, and tools that broadly refer to assisting in the development of a certain class of software. An API (application program interface) is a predefined function or convention for linking different components of a software system in order to provide the application and developer the ability to access a set of routines based on certain software or hardware without accessing source code or understanding the details of the internal working mechanism, i.e. the SDK contains the API function interface.

Example 1

Referring to fig. 1, the present invention provides a method for tracing a textile based on a block chain technology. The property that the data on the chain in the block chain technology can only be added and can not be modified is effectively ensured, the open transparency and the tamper resistance of the transaction are effectively ensured, and the privacy of the user can be further ensured by displaying different corresponding inquiry result information to the inquirer based on different inquirers.

The textile tracing method based on the block chain technology comprises the following steps:

s110: and acquiring the identity identification information of the member user of the login block, and verifying the legality of the member user according to the identity identification information.

As an example, the obtaining identity information of the member user who logs in to the block, and verifying the validity of the member user according to the identity information includes:

issuing a digital certificate based on a CA platform and performing identity authentication; the identity identification information is a hash value obtained by hashing member information by adopting a set algorithm, and the member information at least comprises member ID information.

Specifically, in order to further improve the security in the application scenario in the textile field, the nodes or corresponding members accessing the block are required to perform identity registration, so as to ensure that the traceability information of the product cannot be uploaded and recorded at will. In some embodiments, the identification information is a hash value obtained by hashing member information by using a set algorithm, and the member information at least includes a member ID and/or a name of a party. Wherein, the set algorithm is SHA256 algorithm. Specifically, the system encrypts the user information by using an SHA256 algorithm, and uses a hash value UH obtained by encryption as unique identification information, wherein the encryption algorithm is as follows:

UH＝SHA256(UserInfo)

wherein, the UserInfo is member information, including member ID, participant name and other information.

In some embodiments, the current node and member user issue a digital certificate based on a CA platform and perform identity authentication, which mainly functions to bind the identity of a certificate holder and a related key pair (by issuing the digital certificate for a public key and related user identity information), provide a convenient way for a user to apply, invalidate, acquire, and query the state of the certificate, and implement identity authentication, integrity, anti-repudiation, and confidentiality of each entity in communication by using the digital certificate and related services (certificate issuing, blacklist issuing, timestamp service, etc.). The industrial internet, i.e., the industrial blockchain, needs to issue PKI (public key infrastructure) based certificates to legitimate network members according to its own certificate management component. When a new piece of examination transaction information is generated in the production transaction process of the textile, a sub-certificate can be applied to the root certificate, and members joining the production line need to register in the sub-certificate through the public key of the members, so that the members are guaranteed to have an opportunity to participate in the product circulation process and the safety of the data transmission process only through an authorized node.

S120: and when the member user is legal, recording the related information of the textile in a block corresponding to the member user.

As an example, the related information includes one or a combination of basic information, raw material information, production information, transportation information, and sales information of each related manufacturer; the relevant manufacturers comprise one or a combination of raw material manufacturers, distributors and retailers. Different related manufacturers record related information into different blocks from respective independent systems; and generating a new block for each level of transaction, wherein each block comprises commodity source information, production and transaction node information of each sales relation.

Specifically, the information entered into the block by the raw material manufacturer includes one or a combination of the name of the raw material manufacturer, the country of production of the raw material, the batch ID of the raw material, the serial number of the raw material, the width of the raw material, the name of the transaction manufacturer, the number of the transaction raw materials, the transaction time, the type of the manufacturer, and the cooperation period. The information entered into the block by the manufacturer includes one or a combination of manufacturer name, textile product producing country, manufacturer number, time of shipment, raw material batch number ID, raw material width, design number, production serial number, goods number, money number, goods number (unique ID for identifying goods), and cooperation period. The information entered into the block by the dealer includes one or a combination of the dealer name, the dealer country, the article number (unique ID that identifies the article), the dealer stock time, the sales type, the number of dealings, and the cooperation period. The information entered into the block by the retailer includes one or a combination of the retailer name, retail country, merchandise number (unique ID identifying merchandise), retail lead time, type of sale, retail quantity, and collaboration deadline.

As an example, when there is a business request to trigger a transaction condition, an intelligent contract is executed, and the requester node sends a transaction application to the endorsement node. For example, a dealer is used as a client to initiate an application for transaction with a retailer through an SDK or an API, a supervisor node is an endorsement node, the supervisor verifies a digital signature of the dealer, the intelligent contract is executed in a simulation mode after the verification is passed, when the digital signature of the dealer is verified to be passed and the transaction condition meets the state requirement of the intelligent contract, the supervisor node confirms that the dealer carries out transaction endorsement, the endorsement result is returned to the SDK or the API, and then the dealer applies for sequencing to a sequencing node through the SDK or the API, so that a block chain is updated, and in short, the ledger is updated.

S130: and associating the transaction identification of the block storing the relevant information with the product identification of the product.

As an example, the association relationship between the transaction identifier of the block storing each tracing information and the product identifier of the product is stored in a tracing database outside the blockchain system. Specifically, the transaction identifier (transaction address) may be transferred to the tracing database, and a mapping may be established with the textile tracing code (corresponding to the product number). For example, the mapping relationship of the textile traceability codes and the block addresses of all traceability information related to the textile traceability codes can be stored under the chain. That is, the transaction identification of the storage related information is uniquely associated with the product identification.

S140: querier identity information is determined in response to a received product identification based query request.

And S150, displaying a query result corresponding to the identity information based on the identity information of the querier.

As an example, a digital certificate is issued based on the CA platform and identity authentication is performed, and for a specific authentication manner, reference is made to the technical scheme disclosed in step S110, which is not described herein again.

As an example, the presenting of the query result corresponding to the identity information based on the querier identity information comprises: each inquirer can inquire the transaction data related to the inquirer; the querier can view upstream and downstream transaction data based on the querier, with irrelevant data not viewable.

Specifically, as shown in fig. 2, for example, the query of the distributor a is taken as an example, the data on the distributor a can be queried into the transaction data of the producer a, the data of the producers B and C which are not related to the service are not authorized to be viewed, the downstream data can be queried into the transaction data of the retailers 1, 2 and 3, and the data of other retailers cannot be viewed.

More specifically, when a consumer purchases a textile product at the retailer 1 and desires to perform a traceability query on the textile product, the retailer may display the source of the textile product and the name of the retailer by entering the product number, e.g., "1000001", into the query interface.

As an example, when the tracing query information received by the consumer is inconsistent with the description of the product, in order to prevent an erroneous determination, the consumer may click a "feedback" button of the tracing display page, and input information to be fed back, such as "the origin of the product is inconsistent" or "the retailer is inconsistent", to perform verification, and then receive the verification result again. This allows the erroneous traceability information to be corrected by subsequent feedback information.

The method disclosed by the application can greatly protect the privacy of the user on the premise of effectively ensuring the accuracy of tracing.
