Abstract:In recent years, with the development of computer technology, data computing power under the network environment become more and more strong. In addition, the advent of the era of big data will turn people's daily life, work and study the materialization of information into digital correlation chain, big data through the network resource sharing, simplifies the learning multifarious work, improve the efficiency of work and study. However, the traditional network storage strategy often leaks of data overflow and a series of storage, storage server data security issues. In view of the problem, put forward under the network computing environment, large capacity data security storage strategy research methods. By adopting data correction unit, logic compensation unit and node encryption unit dynamic targeted to solve the traditional network storage strategy. Through the simulation experiments show that under the network computing environment of large capacity data storage strategy research method, a data storage response speed, reverse osmosis, strong logicality, the advantages of high data security, ease of use.
