It is very challenging part to maintain the safety of all stored data which many users want to use in many applications. The stored data in cloud is so important that the users make ensure either the data is corrupted or lost. This work studies the problem of ensuring the mitigation and prevention of data storage in Cloud Computing. This paper, proposes to collect the data and store data in the cloud. The methodology followed is, when any user attempt any wrong password for three times the system take them as an unauthorized user and block the IP address. So, In future they cannot access applications from that IP address and if they are not unauthorized user then they have to send a mail to client so they will unblock the user.
