Data Security for Cloud Mechanisms and Identity Using Cloud Authority

Abstract

Data security for cloud mechanisms and identity is a new encryption technique .In this technique we encrypt the data by using user personal files such as name, emailid, phone number, date of birth etc. Even though there are many encryption techniques the main uses of this one is it is going to reduce the storage of data and hence authorisation time is going to reduce. In this scheme there are three main parts .First one is user, the user requests the data that is present in the cloud. Second one is Admin, if the user is valid hegrants the permission and also he moniters every request time to time and grants the permission .Third one is Data owner he uploads the data. This scheme does doesn’t have the computational overhead. Due to its uniqueness the efficiency is very high and reliable. The sql database is connected in order to store the keys and data. If u compare with diffehellman key exchange it provides more security and decreases the access time .We also can use different types encryption and decryption techniques like vinegar cipher, playfair cipher in order to encrypt the unique files.
