Adaptive Secure Document Access Mechanism in Cloud

Abstract: Cloud data storage has provided massive benefits by allowing users to store huge amount of data in cost-effective manner. To protect the privacy of data stored in the cloud, cryptographic role-based access control (RBAC) scheme combined with context information have been proposed and developed ensuring the restricted access of the documents. The system holds role and context information that enables the upload and download of documents by legitimate users. The security mapper component filters the user information so as to perform adaptive secure document access in cloud.

Keywords: Role-based access control, Context-based access, cryptographic RBAC, secure cloud data storage.
