Dynamic multi-factor authentication for smartphone

Abstract

Nowadays, smartphone has become a vital tool for both productivity and entertainment that most people can't live without it. Due to the widespread usage of smartphone for both personal and professional purposes, many people consider them as private property. This means other people should not be able to freely gain access to their smartphone, because it contains a lot of sensitive data. Therefore, its security is a very important research area with the potential to benefit millions of people in the world. A security system that protects owners from any breaches of privacy is needed to ensure the data inside the device stays private. In this paper, we propose a new system for securing smartphone. We incorporate a multi-factor authentication method to provide high security. Our system also incorporates an implicit authentication method to continuously authenticate the user and prevent unauthorized individuals from accessing the device. A prototype based on the proposed system is also constructed.
