users. Wearables provide a seamless supplement to their main counterparts such
as smartphones, and tablets. With the increasing prevalence of smart devices in a
ubiquitous manner, protecting data has become a crucial aspect of security in all areas
of life, as individuals can be vulnerable to such threats regardless of their location.
As a security measure, authentication measures have been adopted. Traditional/
Legacy Authentication mechanisms such as TouchID, FaceID, and Password/PIN
are incorporated into the everyday life of users. There also exists another mode of
authentication known as continuous authentication, in which the identity of the user is
continuously verified. In this study, we focus on continuous authentication. Existing
state-of-the-art efforts on schemes either require sophisticated sensors, are not
primarily focused towards mobile devices, or require a longer time for making a
decision (due to behavior-based approaches). Furthermore, there is a lack of new
deauthentication schemes thereof.
To address these issues, we propose EMAuth which allows users to remain
continuously authenticated by seamlessly observing their interactions with a smartphone/tablet. EMAuth is a continuous authentication scheme that verifies the identity
of the user in a recurring manner, leveraging both a time-based based on the
received electrical signals due to the user’s interaction with the screen from a wearable.
To validate our scheme, we built a proof-of-concept prototype and conducted
robust experiments to demonstrate high accuracy for both security and usability aspects
and resistance to different attack scenarios.
