Efficient and secure server migration on cloud storage with VSM and dropbox services

Abstract

The huge amount of sensitive data store in centralize storage space in cloud server, which is most important for providing the result based on the user's provided keywords. These service providing high efficiency with keeping user privacy. Without any configure the existing system learn plain text information. CSP (Cloud Service Provider) have outsourced data control in this condition because of some issue. There may survive unconstitutional operation on outsourced information on relation of profit or curiosity. Hence, privacy data has to encrypt for security. In existing search method over encrypted data in cloud support KNN search keyword not multi-keyword rank search based on semantics approach. The search methods aren't intelligent also neglect a few semantically associated documents. In vision of attempt, deficiency an efficient method is suggested to solve multi rank search keyword issue over encrypted information similar search clarification sustaining synonym queries over encrypted information in cloud. To overcome these problems we proposed DMRS search and VSM (Vector Space Model) algorithm. These two algorithms give top ranking search consequence and Security in the cloud storage system.
