Abstract: | User authentication is a key service, especially
for systems that can be considered critical for the data stored
and the functionalities offered. In those cases, traditional
authentication mechanisms can be inadequate to face
intrusions: they usually verify user’s identity only at login, and
even repeating this step, frequently asking for passwords or
PIN would reduce system’s usability. Biometric continuous
authentication, instead, is emerging as viable alternative
approach that can guarantee accurate and transparent
verification for the entire session: the traits can be repeatedly
acquired avoiding disturbing the user’s activity. Another
security service that these systems may need is nonrepudiation,
which protect against the denial of having used
the system or executed some commands with it. The paper
focuses on biometric continuous authentication and nonrepudiation,
and it briefly presents a preliminary solution
based on a specific case study. This work presents the current
research direction of the author and describes some challenges
that the student aims to address in the next years. |
