Effective and Scalable Data Access Control in Onedata Large Scale Distributed Virtual File System

Nowadays, as large amounts of data are generated, either from experiments, satellite imagery or via simulations, access to this data becomes challenging for users who need to further process them, since existing data management makes it difficult to effectively access and share large data sets. In this paper we present an approach to enabling easy and secure collaborations based on the state of the art authentication and authorization mechanisms, advanced group/role mechanism for flexible authorization management and support for identity mapping between local systems, as applied in an eventually consistent distributed file system called Onedata.
