Confidentiality Maintenance of Multiple Keys for Secured Files in Cloud

By the Introduction of the cloud, the owners of the data are tends to manage their complex data from local area to business public cloud because they need more flexible and good savings. To protect the privacy of their data one started to use the encryption techniques for the security purposes, this data will be used for the management. To overcome the traditional usage of data this is based on the plain–text key word search. Our technique solves the confidentiality problems of multiple keys which are in cloud for that we use a rigid confidentiality requirement for secured cloud system for real utilization. "Co-ordinate Matching" is the principle used it matches the similarities between searched query and data docs as many as possible, next technique is "Product inner similarities" to formalize quantitatively for measuring the similarities. The basic MRSE scheme by using product inner matching securely then we improve different requirements of privacy in 2 Levels. The first is analysing and next efficiency we get throughout the process.
