Embodiment Construction

[0048] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0049] The block chain safe storage method provided according to the present invention includes:

[0050] Based on the decentralized storage method of blockchain technology, each client uses an independent program. For example, taking Bitcoin as an example, users maintain their own wallets and transaction records. In addition, a mining program terminal is required to obtain 10 minutes of transaction bill data through real-time competitive calculations, generate a block, and broadcast it to the entire ne...

Abstract

The invention provides a block chain safety storage method. The method makes each client-side Client have a name node, the data storage safety of a big data platform is greatly improved, the pressure brought by a centralized server is effectively avoided by adopting decentration design, and common apportion is performed through a whole privately-owned block chain network; Data Node of each data block of Hadoop is encrypted, and the safety of each data in big data is fully guaranteed. A data storage and management mechanism of the big data platform is further improved, a single mode relying on a central node is converted into a network environment jointly maintained jointly by all participants, and the decentration design is really achieved. By setting PKI and user permission, the shortcoming of simple and extensive plaintext storage of important data is broken through, and a safe and encrypted storage process and method are deepened.

Description

technical field [0001] The present invention relates to the fields of cloud computing and big data, and in particular, relates to a block chain technology and a block chain safe storage method for safe storage of big data. Background technique [0002] The existing technical solutions in Hadoop big data are all based on the HDFS distributed file system to store data. The central nodes are centralized on several servers such as the NameNode. The control of the central node strictly limits the security of the data; specifically, each data block The storage of the DataNode is not encrypted; the traditional storage solution has a simple process and only focuses on data storage without giving full consideration to data security. [0003] After searching, the following relevant search results were found: [0004] Related Search Results 1: [0005] Application (patent) number: 201510955506.2; name: a blockchain traceability method [0006] This patent document relates to a trace...
