Multi - level Authentication Technique for Accessing Organization in Cloud Data

The purpose of this paper is to present the design for providing security and higher authentication scheme for executing secure data transaction in an Organization field over Internet. There has been incessant change in technology day by day, so security mechanisms like authentication schemes are also required to be updated. Authentication schemes that involve more than single level for authentication are moderately safer than one level authentication scheme. Numbers of multi-level authentication schemes have been proposed and implemented in various cloud computing services. In case of Cloud computing, the whole authentication control lies toward the server side. So, it is very tough to trust the third party server in Cloud Computing. This work proposes a scheme in which authentication process is carried out in two levels or multi-levels. In this system, authentication activities take place in organization, team and user levels. First activity happens at organization level. It reads the authentication password and checks to cloud access for organization and then it enters into a second level authentication. The second activity happens at team level. It reads the team login details and checks for authentication. It is a team authentication activity, once authentication done; it then enters into a user level authentication. User level activity reads the authentication information to check for the user permission and privileges.
