The cloud computing allows the users to store the data in the server.The user can store and

retrieve the data from the cloud with in the restrictions provided by the cloud.The user cannot

fully trust the single cloud which he stored his data.The data encryption provide the security

for the user data in the cloud but when the hacker attacks the cloud the data may be

cracked.To overcome these problems the proposed system introduces the method to use the

distinct clouds simultaneously.The proposed methods prevents the cloud to get the full

knowledge about the data.
