Abstract:

Objective- Cloud computing means storing and accessing data and programs over the Internet instead of your computer's hard drive. The cloud is just a metaphor for the Internet. Cloud computing is a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. Cloud computing is often touted as the future of business and enterprise technology where people are subjected to post their personal information like passwords, account number and different confidential data.  It is possible to access data stored in the cloud by intruders or a third person. So the main concern is to provide security of the stored data in the cloud. For ensuring such security self destruction scheme is proposed.

Design / Methodology/ Approach-   A Client-Server approach is used in this system. A cloud server is the main server used, and the user application part is the client part. There is a database for storing the client details. The multicloud feature enables the user to retain the shared data.

Findings- Self destruction of data from the cloud storage is the key feature if this system. All the data get self destructed after a user specified duration.AES algorithm is used for the encryption and decryption. After user specified time period message sent by the sender should be destructed. Any legitimate user can download file till the timeout if and only if the sender is granted permission for that. The file should be encrypted before sending and the decryption of the message is happened to the device after receiving it .By using AES algorithm the users can encrypt their files using and thus making more complexity to the hijackers or he/she cannot decrypt the files more easily. So it reduces major security and privacy issues in the cloud server and can overcome the manual deletion of confidential data’s from cloud server.

Limitations- Storing of data’s to personal devices are restricted for ensuring security but it has to be taken into consideration.

Practical implications- This paper is very helpful for those who require sharing their confidential data and to kept more securely using multicloud methodology.

Originality/Value- The value of this paper is expanding the privacy of shared data in cloud and automatic implicit deletion of data from cloud .It increases the processing speed by self destruction of data on time basis since dumping of data’s in cloud can be avoided.
