Self Destructing Data System Based On Session Keys

Abstract Personal data stored in the cloud may contain account numbers secret codes and other necessary details that could be used and misused. These data can be cashed copied by cloud service provider without users control. We propose a self destructing data which mainly aims at protecting the user datas privacy by making the sensitive data automatically destructed after a period of time. First encrypt the data into cipher text and then distribute both the decryption key and the cipher text into a distributed hash table. To recover the plain text both the decryption key and the cipher text should be obtained from the DHT before the pre-configured period of time.
