Privacy Preserving and Public Auditing Service for Data Storage in Cloud Computing

Abstract

The cloud computing model represents a new paradigm shift in internet-based services that delivers highly scalable distributed computing platforms in which computational resources are offered 'as a service'. Security is considered one of the top ranked open issues in adopting the cloud computing model includes data Integrity confidentiality. Wang proposed a enabling public audit ability and data dynamics for storage security in cloud computing. They achieved the integrity guarantee of data storage with support of public audit ability and dynamic data operations. However their protocol lacks in providing privacy of data which is one of the issue for the cloud data storage. In this we proposed a privacy preserving public verifiability for integrity of data storage in cloud computing. We are using RSA public cryptography to provide confidentiality of data. Our scheme is more secure than existing system.
