INTERNATIONAL JOURNAL OF ENGINEERING SCIENCES & RESEARCH TECHNOLOGY PRESERVING IDENTITY OF SHARED DATA STORED IN THE CLOUD USING PUBLIC AUDIT MECHANISM
A. Chandrasekar · 2015
Cloud Computing has been envisioned as the next-generation architecture of IT Enterprise. The application software and databases are moved to the centralized large data centers, where managing the data and services may not be completely reliable. This work studies the problem of ensuring the integrity and security of data storage in Cloud Computing. We consider a scheme called threshold proxy re-encryption and secure erasure code, to verify the integrity and enhance server-side security of the dynamic data stored in the cloud. In the previous works, ensuring remote data reliability often lacks the support of either public audit ability or dynamic data transactions, this paper achieves both. We first identify the difficulties and potential security problems of direct extensions with fully dynamic data updates from cloud server. In our proposed work we use the multiple servers for storing data to servers. We avoid the additional storage for multi cloud system using split server concept as for security.
