Abstract

Objective: To provide Password authentication by cloud through performing tri stages and also to improve the security. Method: First stage is registration phase; it involves issuing of cloud space to user. Cloud space is used for storing all self information of the client which is used for checking authenticity for later usage. Password of user is generated by user or by server based on password user can registered into cloud. If registration process is completed, then users are able to access the server log-in whenever they needed. Protocol based verification and authentication for two different mediums (Duos) uses user’s cell phones or mobile devices is used as SMS to avoid hacking of password and backtrack attack using password. Using unique phone number Duos system possesses website and involves a telecommunication service provider in recovery and registration phase-in Duos based authentication system user want to remember only the Long-Term Password (LTP) for login in all websites. Efficient and affordable authentication is provided by Duos. For successful login of user’s, they need valid smartcard and correct password. It involves two-factor password phase and cloud space. Findings: Users able to change their password freely in password changing phase and update his/her information to cloud space. Applications/Improvements: The secured web authentication done successfully by using two types of registration which are named as Registration on Website and on the Mobile device. The scalability of the device is achieved.
