Description
Technical Field
The invention relates to the field of identification analysis of industrial internet, in particular to a block chain mode combining an identification analysis index cloud and a hierarchical peer-to-peer network.
Background
The industrial internet identification analysis aims to closely combine all participating objects in the industrial production process, including suppliers, products, equipment, employees, production lines, clients and the like, through an open global information platform, realize sharing and interaction of all information in the whole industrial process, link industrial objects through grasping information of each link, realize optimization of industrial processes, reduce operation cost and improve production efficiency.
The number of identifiers may reach thousands or even more for a single industrial product, and the number of identifiers of the whole industrial internet is hard to imagine in addition to the production line and the supply chain corresponding to the product. Therefore, how to store the huge data and quickly and accurately find the desired information becomes a problem to be solved. Secondly, the security problem of the industrial internet cannot be ignored, and if a hacker invades the industrial internet while the hacker is still in the air, identification information of each link of the industrial internet is stolen, so that the industrial internet is possibly paralyzed, and the loss is irretrievable.
The current common solution is to combine the block chain and the industrial internet identification analysis together, and upload the identification information to the block by using the characteristics of decentralized block chain, non-falsification of information, transparency of information, common maintenance and the like, and the security of the identification analysis data is protected by the shared maintenance of the participating enterprises. However, the block chain has limited storage capacity, and for a more complex industrial system, the conditions of numerous nodes, large data volume and large information flow are necessarily met, and the storage performance of the block chain in the time zone is difficult to meet the requirements. On the other hand, the block chain is only provided with a single-layer peer-to-peer network structure in an identification analysis system, when an enterprise wants to add a new product identification into the system, each node in the block chain peer-to-peer network structure needs to synchronously store a new identification code, when the block chain is large in scale and the nodes are more, in addition, factors such as network fluctuation and delay are added, the storage speed of information is slow, and the efficiency of user downloading and querying is reduced. Therefore, a processing mode is expected, which can reduce the storage time of information, store massive data information, guarantee the safety of stored information, and meet the increasingly complex industrial internet identification analysis requirements nowadays and later.
Disclosure of Invention
The invention provides a block chain mode combining an identification analysis index cloud and a hierarchical peer-to-peer network, which further solves the problems that massive identification data information cannot be stored due to limited storage capacity of a block chain and the requirements of efficient downloading and query of users cannot be met due to low information storage speed of a single-layer block chain structure with large scale and more nodes on the basis of the combination of the existing block chain and the identification analysis of an industrial internet.
In order to solve the problems that the storage capacity of a block chain is limited and the speed of storing information in a single-layer block chain structure is low, the invention adopts the following technical scheme:
the invention provides a block chain mode combining an identification and analysis index cloud and a hierarchical peer-to-peer network, which consists of an index cloud information storage system, the hierarchical block chain peer-to-peer network and a communication structure between the index cloud information storage system and the hierarchical block chain peer-to-peer network.
The identification analysis index cloud information storage system can store mass identification analysis data, carry out hash operation on each data content to obtain a unique hash value, and establish a hash table for retrieval.
The hierarchical peer-to-peer network is formed by two or more layers of peer-to-peer networks. The multi-layer peer-to-peer network is a network structure which divides a complete block chain into two or more layers according to the number of nodes, and when information is stored to the nodes in the network, the information is stored layer by layer from a first layer to a next layer. The network reduces the number of nodes of each layer, reduces the whole network delay of each layer, and improves the information storage efficiency.
The communication structure between the two combines the two systems and is responsible for information transmission between the systems. When uploading the identification data information, the user can directly upload the identification data information to the index cloud information storage system, and simultaneously obtain a unique hash value, and the hash value is stored in a node in the hierarchical peer-to-peer network through a communication structure. When other users have the downloading requirement, the corresponding hash value is provided for the system, and the identification analysis data can be transmitted from the cloud end through the communication structure, so that the data downloading is completed.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the specification of the present application, and it is obvious that the described embodiments are only illustrative and are not intended to limit the present application.
The invention provides a block chain mode combining an identification analysis index cloud and a hierarchical peer-to-peer network, which comprises an identification analysis index cloud system 1, a hierarchical block chain peer-to-peer network 2 and a communication structure 3 between the identification analysis index cloud system and the hierarchical block chain peer-to-peer network.
The identification analysis index cloud system 1 is composed of a file database and a hash index table, file information storage query service and a large amount of storage space are provided, when an enterprise wants to upload identification analysis data, information to be uploaded is directly transmitted into the file database, meanwhile, the index cloud information storage system 1 carries out hash operation according to the content of the data to calculate a unique hash value of the data and stores the hash value into the hash table as an index for query.
The block chain hierarchical peer-to-peer network 2 is composed of two or more layers of peer-to-peer networks and is responsible for storing hash values of data in the index cloud information storage system 1. After calculating the hash value of the newly stored file information, the index cloud information storage system 1 transmits the hash value to the hierarchical peer-to-peer network 2 through the communication structure 3. Unlike conventional blockchain structures, which store information to all network nodes simultaneously, this process takes a long time due to network delay and network fluctuations. And the hierarchical peer-to-peer network stores the hash value into all nodes in the first hierarchical peer-to-peer network, and after all nodes in the first hierarchical peer-to-peer network store the hash value, the outside can be allowed to inquire the hash value in the first layer block chain. And then, storing the hash value into the nodes of the next layer by layer, and diffusing the information to be stored into the whole block chain network.
The communication structure 3 between the index cloud information storage system and the hierarchical block chain peer-to-peer network is connected with the index cloud information storage system 1 and the hierarchical block chain peer-to-peer network 2, and is responsible for transmitting the hash value calculated in the system 1 to the network 2 and transmitting the identification analysis data to be inquired to the user from the storage cloud.
When other users want to inquire the identification analysis data of a certain article in the industrial internet in the system, the system can inquire the node stored by the hash value in the hierarchical peer-to-peer network only by inquiring the hash value corresponding to the part in the shared hash table and providing the hash value, and the identification information or the file content of the part is transmitted from the storage cloud end through the communication structure between the hierarchical peer-to-peer network and the identification analysis index cloud.
The block chain hierarchical peer-to-peer network improves the rapidity and the safety of the block chain to a certain extent. Since the new information is allowed to be queried in the first layer after all nodes of the first layer network store the new information, the storage efficiency is improved. The security of stored information can be enhanced through peer-to-peer network layer-by-layer diffusion, because the structure is different from the single-layer structure of the traditional block chain, the multi-layer block chain structure is equivalent to providing layer-by-layer security guarantee and information backup, the single-layer block chain can be directly paralyzed if being attacked by a hacker, and the multi-layer structure can adopt different security protection on each layer, so that even if a hacker attacks a certain layer, all data cannot be lost, and more opportunities for recovering the loophole are provided for maintenance personnel.
The massive identification analysis data are stored in the cloud end by combining the identification analysis index cloud, so that the storage space on a block chain is saved to the maximum extent, and the non-tamper property of the stored identification data is guaranteed through Hash operation, so that the safety is further improved.
Finally, it should be noted that: the above embodiments are only intended to illustrate the technical solution of the present invention and not to limit the same, and those skilled in the art can make modifications or equivalents to the specific embodiments of the present invention with reference to the above embodiments, and any modifications or equivalents without departing from the spirit and scope of the present invention are within the scope of the claims of the present invention as set forth in the claims.
