Various other advantages and benefits will become apparent to those of ordinary skill in the art upon reading the following detailed description of the preferred embodiments. The drawings are for the purpose of illustrating preferred embodiments only and are not to be considered limiting of the invention. Also, the same components are denoted by the same reference numerals throughout the drawings. In the attached image:

Figure 1 is a schematic diagram of a simple value chain collaboration alliance at present;

FIG. 3 is a block diagram of a data management apparatus based on a multi-value chain collaborative mapping blockchain according to an embodiment of the present invention.

Detailed ways

In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, only a part of the embodiments of the present invention, but not all of the embodiments, and are not used to limit the present invention.

The data management method based on the multi-value chain collaboration mapping blockchain proposed by the present invention, the so-called multi-value chain collaboration refers to the business collaboration on and between multiple value chains of an enterprise, forming a network structure including vertical and horizontal collaboration relationships Value Chain Collaboration Alliance.

For example, take a simple schematic diagram of a value chain collaboration alliance shown in FIG. 1 as an example, wherein T ₁ , T ₂ , T ₃ , T ₄ , and T ₅ represent different upstream raw material suppliers or enterprises. M1, M2, M3, and M4 represent different midstream parts suppliers or enterprises. G ₁ , G ₂ , and G ₃ represent different core manufacturing companies. B ₁ , B ₂ . . . B _n represent different downstream marketers or service providers or enterprises. For the sake of brevity of description, the following full text uses the word "enterprise" to cover all businesses or enterprises involved in the automobile industry, and will not be described separately.

As can be seen from FIG. 1 , between T ₁ to T ₅ , or between any two or any of them, there may be data sharing or business cooperation. T ₁ ˜T ₅ can pass the value to M ₁ ˜M ₄ , and then M1 ˜M ₄ can pass the value to G ₁ ˜G ₃ . Of course, it is also possible that T ₁ -T ₅ directly transfer the value to G ₁ -G ₃ . Finally, the value of G1 _- G3 is transferred to B1 _{- Bn} . Its vertical value chain dominated by core manufacturing enterprises, and the horizontal cross-chain collaboration between vertical value chains constitute value chain collaboration, and finally form a multi-value chain network.

In this multi-value chain collaboration alliance, there may be data sharing or business collaboration at the same level, but there is no data sharing or business collaboration between different levels. This is because the business data between different levels and between different single value chains is not unified. In addition, when data is exchanged between vertical value chains or horizontal value chains, there is no safe and reliable protection method, and data is prone to occur. Leakage, thus causing data siloed across the current value chain.

Based on the above problems, referring to the flowchart of the data management method based on the multi-value chain collaborative mapping block chain proposed by the embodiment of the present invention shown in FIG. 2, it includes:

Step 201 : Determine the overall information of the value chain collaboration alliance, the overall information includes: the type of each value chain, the corresponding business link, the business data corresponding to the business link, and the business operators of the enterprise.

Based on the current value chain collaboration alliance, how to map it into the blockchain system is a core issue. To this end, it is necessary to establish a mapping model for all the information included in the value chain collaboration alliance, taking the core information as the overall information. The overall information of the value chain collaboration alliance includes: the type of each value chain, the corresponding business link, the business data corresponding to the business link, and the business operators of the enterprise.

The so-called type of value chain refers to the core functions corresponding to the value chain. For example: supply chain, marketing chain, service chain, etc. In layman's terms, a supply chain can be understood as a relationship chain formed by selling equipment and materials to other companies or purchasing equipment and materials from other companies. Marketing chain can be understood as a relationship chain formed by selling and selling products. The service chain can be understood as a relationship chain formed after the product is sold.

For each value chain, depending on its type, the corresponding business links must be different, the business links must be different, the corresponding business data must be different, and the relevant business operators must also be different. For example, the business links corresponding to the supply chain may include: production, procurement, production and procurement are two completely different business links, then the business data corresponding to production is different from the business data corresponding to procurement, and the business operators corresponding to production and the corresponding procurement The business operators are also different.

Step 202: Based on the overall information, map to form a blockchain consortium; wherein, based on the type of each value chain, map to form a channel in the blockchain consortium; based on the business links of each value chain, map to form a blockchain consortium. Based on the business data corresponding to the business links, the unified data in the blockchain alliance is formed by mapping; based on the business operators of the enterprise, the users in the blockchain alliance are formed by mapping.

Based on the above-mentioned value chain collaboration alliance, when mapping the blockchain, it is a better choice to map in the form of a blockchain alliance. As a blockchain alliance, in addition to comparing the core overall information, it is also necessary to combine other information , the value chain collaboration alliance can finally be mapped to form a blockchain alliance.

Based on this consideration, the overall information of the value chain collaboration alliance is represented by a quintuple to map to form a blockchain alliance. The quintuple corresponding to the blockchain alliance U is as follows:

U={U _id , U _name , U _E , U _A , U _C }

Among them, U _id is the unique identifier of the blockchain alliance to distinguish it from other blockchain alliances. U _name is the name of the blockchain alliance, U _E is the channel set in the blockchain alliance, the channel corresponds to the value chain, and the channel set is the set of the corresponding value chain.

U _A is the set of channel administrators in the blockchain alliance. Generally, because there are multiple channels, each channel may contain multiple business operators. In order to facilitate the management of channels, some of the business operators are selected as the The channel administrator has high authority to manage and maintain the channel.

_UC is the cooperation condition of the blockchain alliance. The so-called cooperation conditions include: the access conditions, cooperation declaration, and privacy declaration of each value chain. Each value chain that needs to join the blockchain alliance must meet the cooperation conditions before joining. . There are many options for blockchain alliances, and a better option includes: Fabric alliance.

For between each value chain and each channel: each value chain is mapped as a channel of the blockchain alliance, and the channels mapped by all value chains in the multi-value chain form a channel set U _E .

For each channel E _i can be represented by a six-tuple as follows:

E _i ={E _id ,E _name ,E _type ,E _org ,E _node ,E _user }

Among them, E _id is the unique identifier of the channel E _i to distinguish it from other channels. E _name is the name of the channel E _i , and E _type is the type of the channel E _i , that is, the type of the value chain, such as the aforementioned supply chain, marketing chain, service chain, and so on. If there are two supply chains: supply chain 1 and supply chain 2, there are also two corresponding channels. It should be noted that the blockchain is an overall system with a huge amount of data and computation. Based on the limitations of the current hardware device performance, the computing power of the blockchain system is determined by the performance of the hardware device. Therefore, in order to improve the computing efficiency of the blockchain system, it can be stipulated that an enterprise can only join one of the channels of the same type. That is, for each enterprise, if it joins the corresponding channel of supply chain 1, it cannot join the channel corresponding to supply chain 2, and if it joins the channel corresponding to supply chain 2, it cannot join the corresponding channel of supply chain 1. Of course, in the case where the computing power is completely sufficient, there is no need to impose restrictions.

E _org is the organization set of channel E _i , that is, the set of enterprises in the corresponding value chain, and the same channel may include multiple enterprises. E _node is the node set of channel E _i , that is, the set of enterprise business links corresponding to the value chain and the set of functional links of the channel, that is, multiple enterprises have the same business links, and these same business links form the combination of business links. E _user is the user set of the channel E _i , that is, the set of enterprise business operators corresponding to the value chain.

For business operators and users of the blockchain alliance: map the business operators of the enterprise to users in the blockchain alliance, and perform information management and permission control for users through the user management module of the blockchain alliance.

The user _Usri in each blockchain consortium is represented by a quadruple as follows:

Usr _i ={Usr _id ,E _id ,Usr _authority ,E _node }

Among them, _Usrid represents the unique identifier of the user _Usri , and E _id represents the enterprise where the user _Usri is located. The combination of the two can distinguish all business operators.

U _srauthority represents the authority set of the user _Usri , the authority may include: blockchain management authority, enterprise administrative management authority, E _node indicates the set of business links related to the user _Usri , and the user management module performs user actions based on the quadruple. Permission control for business activities.

For between business links and blockchain alliance nodes: map the business links to nodes in the blockchain alliance, in which business operators participate in the business links according to their respective functions; through the node management module of the blockchain alliance to achieve Business management, including: access control, creation and deletion, deployment and offline of nodes; through the transaction management of the blockchain alliance to promote the business process of business links, business links include: procurement, warehousing, distribution, processing, production, Sales, repairs, maintenance and settlement. Of course, it can be understood that there may also be other business links, which are not described one by one in this embodiment of the present invention, and may be added or deleted according to actual business links.

Each business link corresponds to one type of business processing. The business processing includes: collaborative business and simple business. One business link Si is _represented by a quintuple as follows:

S _i = {S _id , S _name , S _node , S _user , S _task }

Among them, S _id is the unique identifier of the business link Si, S _name is the name of the business link Si, _{S node} is the related _node set of the business link Si, S _user is the participating user set of the business link Si, and _Stask is the set of participating users of the business link Si _. The business delivery conditions of the business link _Si , only when the delivery conditions are met, the business link can be executed normally.

The blockchain alliance conducts transactions and records the results of business processing by means of endorsement; among them, simple business needs to apply for non-transferable endorsement, and non-transferable endorsement is to grant specific asset rights to users to exercise, including: asset use endorsement and mortgage endorsement. It can be understood that a simple business is a business within an enterprise and does not have business relationships with other enterprises, such as warehousing, processing, etc.

Collaborative business needs to apply for transfer endorsement. Transfer endorsement is to transfer the rights of the asset owner to other users, including: asset transfer endorsement. It can be understood that a collaborative business is a business relationship between an enterprise and other enterprises, such as purchasing and sales.

In terms of implementation, smart contracts can be used to create a business smart contract (called chain code in the Fabric Alliance) for each business type (also called business link), and name it `xxxCC.go`. The business smart contract file encapsulates a set of functions that perform related business operations on asset status, such as adding, deleting, checking, and changing functions. In the Fabric Alliance, whether it is a read-write business or an asset transfer business, it is necessary to initiate transactions and call chain codes.

For the business data corresponding to the business link and the unified data of the blockchain alliance: the business data corresponding to the business link is managed and uniquely identified through the corresponding value chain identification, enterprise identification and data identification, so as to distinguish the business link The corresponding business data is represented uniformly.

The business data D _i is represented by a seven-tuple as follows:

D _i ={D _id ,D _Uid ,D _Eid ,Meta,I,O,D _sig }

Among them, D _id is the unique identifier of the business data D _i , D _uid is the unique identifier of the collaboration alliance to which the business data D _i belongs, D _Eid is the unique identifier of the enterprise to which the business data D _i belongs, and Meta is the business data D _i and unified data Represents the mapping relationship of the structure.

Meta is represented by a five-tuple metadata model, denoted as Meta:<T,E,V,O,R>;

I={I ₁ , I ₂ ,...,I _n } is the set of business data D _i input interfaces, where n is the number of input attribute parameters;

O={O ₁ ,O ₂ ,...,On } is the set of business data D _i output interfaces, where _n is the number of output attribute parameters;

D _sig ={D _sig1 ,D _sig2 ,...,D _{sigm }} is the signature set of the service data Di, used to determine the authority ownership of the data, where m is the number of signatures.

Any data entity in the business data D _i is conceptually defined with an ontology, and the data entity includes: the category, attribute and relationship of the data entity.

Based on the above definition, establish the metadata model of Meta, where T is the atomic term set, which includes: atomic term C and atomic attribute term P, then T=<C, P>; E is the term interpretation set, whose references are ready-made vocabulary to define and explain terms; V is the term value set; O is the data entity set, which is described by the Cartesian product of the term set T and the term value set V, then T*V→O; R is the data entity's A relationship set, which describes the binary relationship between data entities.

In the specific mapping of each enterprise, taking into account the structure of the enterprise itself, the enterprise entity can be used to map concepts such as departments, businesses, and assets in the enterprise to the blockchain concept, and establish and design corresponding entities for it. Relationships are established between entities through transactions. Considering that automotive industry data is usually structured or semi-structured data, the mapping relationship between relational data representation and ontology data representation is designed. Generally speaking, a relation table can correspond to an ontology category, and each ontology instance (entity) describes the entity portrait through attributes.

For every business there are:

Based on the basic information of the enterprise, it is mapped to form an organization with the category of blockchain. The basic information of the enterprise includes: enterprise number, enterprise name, enterprise type, enterprise location, and enterprise value chain. The enterprise value chain includes: the corresponding value chain number and corresponding value chain;

Based on the basic information of the business link of the enterprise, the mapping forms the ontology of the blockchain node. The basic information of the business link includes: business link number, business link name, business link type, and departments participating in the business link. The business link type includes: Purchasing, warehousing, distribution, processing, production, sales, repair, maintenance, settlement;

Based on the business data of the enterprise, the mapping forms an ontology whose category is the business data;

Based on the asset data of the enterprise, the mapping forms an ontology whose category is asset data;

Based on the value chain involved in the enterprise, the mapping forms an ontology with the category of blockchain, and one of the value chains is mapped to a blockchain;
