Cloud Computing is arising on-demand, ubiquitous internet based technology, which provides variety of services. Cloud computing offers various services like software, hardware, data storage, platform, infrastructure etc. major weakness with data security over cloud is that, the but of physical security control is not viable. Appropriately, strong approach control and authentication becomes extremely vital for providing valuable security. Number of protection and privacy issues rise be-coming to the outsourcing of infrastructure, delicate records and critical application and its multitenancy environment. In this research paper, we are proposing authentication technique and multifactor user authentication for prevent illegal access over cloud. As our proposed technique using three tier of authentication check, authentication image check and authentication codes. To provide further security on client side, we are using a special keyboard and on the server side authentication code is store in encrypted form on master server at different tiers. Our proposed technique is quite more secure.
