Abstract

In the cloud era, cloud storage has become a major service and the security of data and user privacy algorithms are becoming of great importance. This way, we make sure that the encrypted data is kept in the cloud storage. But, the challenges follow: First, storing encrypted data may result in ineffective utilization of cloud resources as in the provision of encrypted data, redundancy cannot be provided. Access control to the encrypted data is difficult as the underlying data is hidden and there is no metric with which the decision to share among users can be easily taken. Deduplication is an approach that can be applied to remove the duplicated data, consequently improving the storage capacity. But, the issues in the seamless implementation of deduplication with the encrypted data is due to the fact that the encrypted data looks unique no matter what the original content is. Access control involves the use of methods and policies that decide who gets the data and which actions they can undertake while working with the data. This initiative is committed to designing a plan that deals specifically with the given issues. The system proposed brings de-duplication of data before encryption by using hashing techniques so that the storage efficiency may be enhanced. It also offers easy decentralized management of the keys for the encrypted data as well as a possibility to securely share the data among authorized users. The scope of this effort is to approve the workflow for file upload, as well as the user access control from one user to another within an organization.
