Study of data security and privacy preserving solutions in cloud computing

Abstract

Cloud computing is a rapidly growing model of computation. It is the delivery of computing services by shared resources, software and information over the network (Internet or Intranet). It allows user to store large amount of data in cloud storage and use as when required from any part of the world by networks. Cloud computing is network based technology since security issues like privacy, data security, confidentiality etc. are encountered. It has a number of users, who are using cloud services like social network, email, file-sharing and other which are increasing the data load in cloud storage regularly. It is also increasing the risk of data vulnerability. Therefore, the data security must be provided in cloud computing models. There are some solutions proposed, to resolve these issues, based on encryption techniques. The main contribution of this paper is to perform a study of different solutions to provide data security and privacy in existing cloud computing scenario.
