Cloud computing has been envisioned as the next generation information technology architecture for enterprises. Cloud Computing moves the data on the cloud storage servers maintained by service providers, which deprive the user of their control of the physical possession of data, even though they are the owners of the data. This unique feature however has raised many new security challenges which have not been well understood. In this paper, the authors introduce a framework and efficient constructions for Dynamic Provable Data Possession (DPDP), which extends the PDP model to support provable updates on the stored data.
