We present Cued Gaze-Points (CGP) as a shoulder-surfing resistant cued-recall graphical
password scheme where users gaze instead of mouse-click. This approach has several …

Shoulder-surfing is a known risk where an attacker can capture a password by direct
observation or by recording the authentication session. Due to the visual interface, this …

Graphical passwords have been proposed to address known problems with traditional text
passwords. For example, memorable user-chosen text passwords are predictable, but …

Click-based graphical passwords have been proposed as alternatives to text-based
passwords, despite being potentially vulnerable to shoulder-surfing, where an attacker can …

Click-based graphical passwords have attractive usability properties, such as cueing and
good memorability. However, parameters such as image size and number of click-points in …

In this paper, an improved carrier frequency offset estimation method which is less sensitive
to timing offset is proposed. The method is based on the carefully constructed frequency …

Identity theft refers to the preparatory stage of acquiring and collecting someone else's
personal information for criminal purposes. During the past few years, a very large number …

Despite the ubiquity of password systems, knowledge-based authentication remains an
important and active research area. Many current systems have low security, and even then …

In this paper, the connection between triangular number (T n), square number (S n) for
construction and counting the A 2 lattice number in lattice vector quantization is presented …
