Enabling Efficient Cloud Storage and Privacy Preservation with Cloud Auditing

Abstract

With the substantial growth in cloud storage, the users for data outsourcing towards cloud servers are drastically increased. Subsequently, increasing data volume over the cloud has led to enormous data duplication. However, the cloud server maintains the unique copy of original data over the storage system; but leads to an immeasurable loss when the data is missing or corrupted. However, duplicate file maintenance and auditing integrity are extremely essential in the industrial and academic field. It helps to maintain the file over the cloud in a secure and protected manner. In this research work, a secure file maintenance scheme over cloud storage with cloud auditing is proposed to maintain the duplication copy of the file by encrypting the files. It helps in the integrity of public auditing of every copy with reduced storage. Specifically, the cloud auditing establishes secure authentication with tag-based duplication. Next, this proposed model uses appropriate encryption techniques to fulfil the confidentiality of data during the auditing integrity and duplication process. This work pretends to support every data owner to maintain data integrity and periodically delegate third party auditing (TPA) independently to deal with the multiple auditing strategy for outsourced data. Thus, the proposed model achieves better security and confirms the performance by performing simulation over MATLAB environment. The experimented results give better trade-off in contrast to prevailing approaches.
