Privacy Preservation Using Novel Identity Management Scheme in Cloud Computing

The Cloud Computing is known for its high availability and low cost in implementation and maintenance. The Users of Cloud often give their secret credential for accessing application and/or data hosted on Cloud environment. Authentication is today´s one of the most challenging issues in the domain of security and privacy for the applications running under Cloud environment. As users´ access more than one service, sometimes using common credentials, User feels unsafe about disclosing their identity on the Cloud environment because their information may be used with other application/users to generate knowledge about their activities. In this paper, we propose a model which allows users to authenticate to the service securely and control the disclosure of their attributes. The proposed model offers users´ a flexibility to generate instant identity along with credential required to authenticate service provider. The instant identity for each service provider makes tough for them to track user´s access patterns. Due to rapid change in identity, service provider may not be able to locate user(s). The proposed model aims to assists the users to preserve privacy of their data.
