Problems solved by technology

[0009] The present invention aims at the above-mentioned problem of naming conflicts caused by different attribute names of database tables when sharing data between different databases, and the problem of data being tampered and lost when the data is already managed by the traditional data center. Learning technology, learning standard data features through machine learning, used to identify text with the same semantics, so as to realize the method of multi-database security sharing to third parties through the blockchain network

Embodiment Construction

[0032] The technical solutions for realizing the object of the present invention are further described below through specific examples. It should be noted that the technical solutions claimed in the present invention include but are not limited to the following examples.

[0033] This embodiment discloses a cross-system data sharing method based on blockchain and machine learning, including the steps of establishing a semantic web database, establishing a standard attribute value database, and sharing smart contract data.

[0034] Said Semantic Web database establishment step, in general, each block in the block chain has set up a Merkle tree structure in order to save transaction records, wherein the block header saves the root of the Merkle tree, and the block body saves the following For the part below the corresponding tree root, a similar Merkle tree structure can be used to build a semantic web database, and an attribute name for recording all types of data in the shared ...

Abstract

The invention discloses a cross-system data sharing method based on blockchain and machine learning, belongs to the technical field of blockchain networks, and particularly relates to a cross-system data sharing method based on blockchain and machine learning, which comprises a semantic network database establishment step, a standard attribute value library establishment step and an intelligent contract data sharing step, and utilizes blockchain and machine learning to solve the cross-system data sharing problem. The blockchain technology can ensure that data cannot be tampered and the security of the data can be ensured, data processing and related business operation are realized by utilizing an intelligent contract formed by automatic script codes, and the method is used for recognizingtexts with the same semantics by utilizing a machine learning technology and learning standard data characteristics through machine learning. Therefore, the multi-database security sharing method forthe third party through the blockchain network is realized.

Description

technical field [0001] The invention belongs to the technical field of block chain network, and in particular relates to a cross-system data sharing method based on block chain and machine learning. Background technique [0002] A database system (Data Base System, referred to as DBS) is a system composed of a database and its management software. The database system is an ideal data processing system developed to meet the needs of data processing. It is also a software system that provides data for the actual operable storage, maintenance and application systems. It is a storage medium, processing object and management system. aggregates. [0003] A database system typically consists of software, a database, and a data administrator. Its software mainly includes operating systems, various host languages, utilities, and database management systems. The database is managed uniformly by the database management system, and data insertion, modification and retrieval must be p...
