Problems solved by technology

[0007] (1) There are many distributed storage and computing nodes for big data. If a node is compromised, it will lead to a large amount of data leakage of this node and other nodes
[0008] (2) Once the unified identity authentication center service node is breached, it will cause the paralysi

Embodiment Construction

[0041] Glossary:

[0042] Hadoop: It is a software framework capable of distributed processing of large amounts of data, the core design is HDFS and MapReduce. HDFS provides storage for massive data, and MapReduce provides calculation for massive data.

[0043] Decentralization: The influence between nodes will form a non-linear causal relationship through the network. Decentralization refers to an open, flat, and equal system phenomenon or structure.

[0044] Blockchain, a technical solution for collectively maintaining a reliable database through decentralization and trustlessness. It is mostly used in user authentication, custody of assets and smart contracts, etc., and value exchange can be completed without third-party access.

[0045] The process of applying blockchain technology is essentially the process of organizing block content and demonstrating the rationality of consensus agreements.

[0046] A smart contract is a computer program based on the blockchain that...

Abstract

The present invention discloses a block chain-based big data security authentication method and system. The method comprises the following steps that a big data node A broadcasts its identity authentication in the whole network; all other big data nodes in the whole network record the identity authentication; if the big data node A is accessed in authentication, the big data node A releases a transaction package including a timestamp in the whole network, the other big data nodes in the whole network check the transaction package, and determine whether the transaction package is consistent with transaction packages stored by the other big data nodes; if the determining results of other big data nodes are consistent, the transaction package is determined legal, and the big data node A is added to a big data block chain; and the security authentication of the big data node A succeeds. Through adoption of the method and system, the network robustness is improved, the management process is simplified, and the operation and maintenance cost is saved.

Description

technical field [0001] The invention relates to the field of big data technology, in particular to a security authentication method and system based on big data technology. Background technique [0002] The current big data center is mainly built on the basis of the Hadoop ecosystem. The exposure of the big data platform makes the big data containing massive data and potential value easier to attract hackers, and it is easier to generate identity verification, authorization process and input verification, etc. A large number of security issues; there are loopholes in the security protection of big data itself. Although cloud computing provides convenience for big data, the security control of big data is still not enough. [0003] According to the degree of confidentiality of big data and the needs of users, different permission levels can be set for big data and users, and strict access control can be carried out to ensure the application security of big data. Therefore, i...
