A Semantic and Robust Authentication Scheme for User-Based Access Control on Cloud Storage

Cloud computing and cloud related services are gaining ground in today’s technology driven world. It allows an individual to delegate their work and store it in the cloud. The cloud provides pay per usage kind of services to the users. However, this model of services needs to ensure privacy and authentication so that only authorized users can access resources in the cloud. In this paper, we proposed a user authentication architecture that aims to improve user authentication for different cloud services and simultaneously incorporating a fine-grained access. A blockchain based approach is used to provide the security. We tested the architecture with two different scenarios and the result proves that the approach is effective and secure.
