Data safety protection method and device based on data partitioning

Abstract

The invention discloses a data safety protection method and device based on data partitioning. The method includes the steps that private data are extracted out of original data according to a preset private data extraction rule and partitioned into private data and non-private data; padding data are added to the private data, and encrypted data are obtained; a mapping table is generated according to the serial number of the private data, the padding data and the encrypted data; meanwhile, an index table is generated according to the serial number of the private data, nouns of the mapping table and original file names corresponding to the private data; an information safety card of the private data is generated according to the mapping table and the index table, and the information safety card of the private data is stored in a database according to preset private data storage strategies. According to the data safety protection method and device, the data are partitioned, the private data generate the mapping table and the index table, the information safety card of the private data is established, storage is conducted through different strategies, storage and reading efficiency is improved, and data portioning and encrypting difficulty is greatly simplified.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a method and device for data security protection based on data segmentation. Background technique [0002] In the era of big data, data storage, reading and writing, and security have become major issues of general concern. The rapid popularization of the Internet has made data no longer isolated, and data sharing has become the mainstream. The rise of e-commerce has highlighted data security issues, which has greatly impacted traditional security management strategies. In the absence of protection, users Any information stored and transmitted on the network has the possibility of being tampered with and leaked. High-tech crimes and hacking incidents occur frequently, ranging from personal interests to national interests have been seriously violated. Data encryption technology is an effective and feasible way to solve information security problems and realize data confide...

AI Technical Summary

Problems solved by technology

[0004] Since the existing data security protection method directly uses encryption technology to encrypt data without distinguishing different types of data, and the encryption method is usually relatively complicated, the present invention proposes a data security protection method and device based on data segmentation
