Research on the Cloud Computing Storage Privacy Preserving Based on MB-Tree Dynamic Access Model

Abstract

Cloud computing is the most anticipated revolution in the computer field. It has the ability to distribute the resource dynamically. According to the needs of the client service, with the lowest cost to solve the computer information processing, it creates hope for the computer technology innovation. But cloud computing has certain vulnerabilities for privacy in the network environment. Because the resource is allocated dynamically, privacy information is easy to be stolen. This paper improves MB-Tree model, gives the ability of protecting customer privacy information dynamically, and establishes the mathematical model and algorithm of dynamic MB-Tree. In order to verify the algorithm, finally we verify the algorithm of MB-Tree model, in which dynamic protection effect of privacy information with different time is up to 98%, protection effect of different data is up to 96%. The privacy information of cloud computing is got better protecting effect.
