Data owner centric approach to ensure data protection in cloud environment

Abstract

Last few years the latest trend of computing has been cloud computing. Cloud has brought remarkable advancement in individual as well as IT sector. But still many organisations are lagging behind in using cloud services. Major issue that affect them is related to data protection at cloud and afraid of sensitive data leakage by intruders. To solve this problem a data protection model has been designed so that data owner feels free to use cloud services. Proposed model is highly secure and data is under control of data owner itself. Re-encryption, HMAC and Identity based user authentication techniques are used in this model to make it more effective and attractive to use this model in real world.
