File Operation using Secrete Sharing & Hadoop

Abstract

In today’s high tech technology modern world everyone mostly store their Personal data in the Cloud which may has passwords, account numbers and other important information that may be used and misused by a miscreant, a opponent, or a court of law. These data are read, copied, and archived by Cloud Service Providers (CSPs), often without authors permission and control. Self-destructing data plays a very important role in protecting the user data’s privacy. All the data stored at servers and their copies destroyed after a user-specified time, and also this data became unreadable for any user intervention. The decryption key is destructed after the user-specified time that is ttl(time-to-live) field. In proposed system, we present self-destructing data system that meets this challenge through a novel integration of secure cryptography techniques with active storage techniques based on ‘hadoop’. We implement a proof-of-concept SeDas prototype. By functionality and security properties evaluate the SeDas prototype, the results conclude that SeDas is practical to use and achieve all the privacy-preserving aims described. Compared to the system without self-destructing data mechanism, performance of uploading and downloading with the proposed SeDas acceptably decreases, while latency for uploading and downloading operations with self-destructing data mechanism increases.
