There are many authentication schemes that are in practice today. If they are categorized based on usability and security then most of them fall into the category of security that ensures the safety of the user’s account using second factor, but they lack proper usability. The remaining are the authentication schemes that are designed to achieve better usability, but lack proper security to protect the user from communication channel attacks and masqueraded server attacks. This research was aimed at providing authentication schemes that shall bridge the gap between security and usability. The idea of the project is to setup a Security system which is more secured for a door lock or a bank locker. The idea is to design a prototype using a onetime password (OTP) to unlock. This is an embedded system which helps to increase the security.
