Which of the following are the benefits of Keystroke dynamics?

A.
Low cost

B.
Unintrusive device

C.
Transparent

D.
All of the choices.

Explanation:
Keystroke dynamics is behavioral in nature. It works well with users that can “touch
type”. Key advantages in applying keyboard dynamics are that the device used in this
system, the keyboard, is unintrusive and does not detract from one’s work. Enrollment
as well as identification goes undetected by the user. Another inherent benefit to
using keystroke dynamics as an identification device is that the hardware (i.e.
keyboard) is inexpensive. Currently, plug-in boards, built-in hardware and firmware, or
software can represent keystroke dynamics systems.
