Multi-level authentication technique for accessing cloud services

Cloud computing is an emerging, on-demand and internet-based technology. It provides variety of services over internet such as, software, hardware, data storage and infrastructure. This technology has been used by worldwide customers to improve their business performance. However, to utilize these services by authorized customer, it is necessary to have strict authentication check. At present, authentication is done in several ways: such as, textual, graphical, bio-metric, 3D password and third party authentication. This paper presents the strict authentication system by introducing the multi-level authentication technique which generates/authenticates the password in multiple levels to access the cloud services. In this paper, details of proposed multilevel authentication technique are presented along with the architecture, activities, data flows, algorithms and probability of success in breaking authentication.
