Secure Cloud Storage Auditing Using Hash-Code Technique

Abstract

The Main objective of the project is to provide hash-value security to the data of the data owner. Every data dynamically generates some blocks of code then every block will have hash code. This hash code or value is totally dependent on the data it contains. First data will be encrypted at client side itself afterwards it will generate hash value of that block. With this technique we are aiming to provide high level security to the data in cloud. The Major problem lies in the security of the data in cloud where a user totally trusts on a remote server to store their data securely. There is numerous amount of studies have been conducted to address the issue of block level security. Untrusted servers need high level infrastructure to overcome the issue of data security in cloud. Hash Value based security is a well formed and clearly examined technique over a period of time in cloud. It converts the actual data with a secure unreadable code called as hash value. It is a key-value pair in which elements are arranged or organized in dictionary entry object.
