Ensuring Privacy in Data Storage as a Service for Educational Institution in Cloud Computing

Cloud computing is an emerging computing technology that allows us to implement their own services using on-demand IT infrastructures.1 The idea behind this approach is to provide a new model of infrastructure provisioning which can create elastic on-demand IT infrastructures according to the changing requirements. In our work we have proposed to use this on-demand service for data storage typically in an Educational Institution. But, this new technology suffers security issues. To solve this problem we have proposed to incorporate public audit ability and data dynamics for Data Storage as a Service with a Trusted Third Party auditor. Thus making the owners of the data to store their data remotely in the cloud data storage and thereby making them to enjoy on-demand high-quality data storage service from the shared pool of data storage.
