Data security and integrity in cloud computing : Threats and Solutions

Abstract

Cloud computing changed the world of Internet. With the help of cloud computing user can easily share, store and retrieve their data from anywhere. Cloud computing is scalable, fast, flexible, and cost-effective technology platform for IT enabled services over the internet. Cloud computing provides hardware, software and infrastructural storage to many users at a time Most of the times cloud users don’t know the exact location of their data or the sources of data stored with their data. In spite of various benefits that are provided by the cloud computing services, its users are very much afraid about the security of their data once it is over the cloud under the control of third-party vendors. Therefore, many data security and integrity concerns like access control, searchable encryption techniques, key management, ownership proofs and remote integrity check arise. This paper discusses the security and integrity of data in cloud computing. It is a study of aspects related to data security. The paper will go in to details of few data protection methods and approaches used throughout the world to ensure maximum data protection by reducing risks and threats. Going ahead the paper also discuss different techniques used for secured data storage on cloud.
