Cloud storage is a prominent storage plan and is widely accepted. Data’s from cloud can be accessed at any time and from anywhere. Most of us believes that data in cloud cant be hacked. But in reality the data can be grabbed by illegitimate users. In this work we have created fake documents to misguide intruders to prevent illegal access. We setup an encryption method that convinces the intruders. A superior encryption method such as Cipher text Policy Attribute Based Encryption method is used and it helps to promote user’s privacy. Only right user can attain the right data by using this technique. We also modify the system by introducing a new method such as once the file is deleted from cloud the key authority serve public key for restore again the file only based on some resembling conditions connected the attributes with that file.
