Preserving Privacy In Public Auditing For Data Storage Security In Cloud Computing

Abstract

This paper is proposed  “to computerize the cloud computer. This system was developed in Asp.net as front end, the Microsoft SQL Server as the back end and Windows XP as platform. Computers today have become indispensable tools. They are fast changing the way in which work is done by their speed, accuracy and diligence. Almost all good businesses practices have embraced computers for increasing the productivity and efficiency, which ultimately results in profits. Cloud computing is the long dreamed vision of computing as a utility, where users can remotely store their data into the cloud so as to enjoy the on-demand high quality applications and services from a shared pool of configurable computing resources. By data outsourcing, users can be relieved from the burden of local data storage and maintenance. Thus, enabling public auditability for cloud data storage security is of critical importance so that users can resort to an external audit party to check the integrity   of outsourced data when needed. To securely introduce an effective Third Party Auditor

(TPA), the following two fundamental requirements have to be met:

1) TPA should be able to efficiently audit the cloud data storage without demanding the local copy of data.

2) Introduce no additional on-line burden to the cloud user.
