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 …

Conventional computer systems authenticate users only at the initial log-in session, which
can be the cause of a critical security flaw. To resolve this problem, systems need …

Biometrics is rapidly gaining acceptance as the technology that can meet the ever
increasing need for security in critical applications. Biometric systems automatically …

User authentication is the process of verifying whether the identity of a user is genuine prior
to granting him or her access to resources or services in a secured environment …

Biometrics have the potential to solidify person-authentication by examining" unforgeable"
features of individuals. This paper explores issues involved with effective integration of …

The mobile device has become a ubiquitous technology that is capable of supporting an

Acquiring samples. During a user's first contact with the biometric system, the system collects
a biometric sample using an input device. The quality of the first sample is crucial …

We hypothesize that an individual computer user has a unique and consistent habitual
pattern of hand movements, independent of the text, while typing on a keyboard. As a result …

Continuous authentication has been proposed as a possible approach for passive and
