Research on keystroke dynamics biometrics has been increasing, especially in the last
decade. The main motivation behind this effort is due to the fact that keystroke dynamics …

Personal Identification Numbers (PIN) and unlock patterns are two of the most often used
smartphone authentication mechanisms. Because PINs have just four or six characters, they …

In this paper we focus on a context independent continuous authentication system that
reacts on every separate action performed by a user. We contribute with a robust dynamic …

Authentication methods using personal identification number (PIN) and unlock patterns are
widely used in smartphone user authentication. However, these authentication methods are …

User Specific traits are a very strong method to strengthen the security of any system as it
makes the system connected to a specific individual instead of being accessed through …

Keystroke-based behavioral biometrics have been proven effective for continuous user
authentication. Current state-of-the-art algorithms have achieved outstanding results in long …

Most existing computer and network systems authenticate a user only at the initial login
session. This could be a critical security weakness, especially for high-security systems …

Free text keystroke dynamics is a behavioral biometric that has the strong potential to offer
unobtrusive and continuous user authentication. Unfortunately, due to the limited data …

The COVID-19 pandemic has accelerated the development of distance learning
technologies, where online tests and exams play an important role. In online testing, the …

Information security plays critical roles in modern society. However, traditional security
measures like passwords, tokens and personal ID numbers only provide limited protection …
