Due to the widespread usage of mobile devices for both personal and
professional purposes, many people consider them to be private property.
This means other people should not be able to freely gain access to their
mobile devices, because they contain a lot of sensitive data. Therefore,
security in mobile space 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
mobile devices stays private.
In this study, we propose a new system for securing mobile devices. 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
mobile device. A prototype based on the proposed system is also constructed.
