From passwords to keystrokes: an evolution in user identification technology

An evolution in user identification technology
Gone are the days of remembering long, complicated, case-sensitive
passwords. Or are they? With new user identification technologies on the
market, passwords might be going obsolete. But are these new
technologies really as effective as a strong password? With the common
problem of using the same passwords on different online accounts, and
the proliferation of password-cracking software and techniques, it turns
out that these new sci-fi-style technologies might be even more
reliable.
Keystroke identification is one of the new technologies replacing
password identification in some companies and organizations, and is
getting more and more attention in the computer security community. This
technology works by monitoring keystroke dynamics – a person’s unique
typing patterns. Likened to “handwriting of the digital age”, keystroke
identification makes security more human-friendly than passwords (which
can be easily cracked, especially if they contain words instead of
random characters, and can be forgotten by the user), and allows for
more continuous authentication as opposed to one-time password
authentication. This is good as the computer system will be able to
detect if a user has changed mid-session.
Typing dynamics can be captured through various identifying components
including but not limited to latency between consecutive keystrokes,
dwell time (time duration in which a key is pressed), flight time (time
between releasing a key and pressing the next one), typing speed and
error frequency (use of backspace button). These identifying components
can be as unique as a hand-written signature.
Although keystroke identification is high-tech, and right up there with
retina, fingerprint and facial feature recognition, there is some
skepticism surrounding its efficiency. Unlike the other biometric
technologies, typing patterns are not as consistent over time and can be
erratic, even throughout the course of a day. And there are also
concerns about keystroke loggers overriding this type of authentication
system.
But skepticism aside, authenticating a computer user by keystroke just
might be the key to stronger online security because it is not that
recent a technology, and has been studied for longer than most people
know. According to Chairunnanda et al., the study of the manner in which
people type goes back as far as Morse code. Apparently, Morse code
wasn’t only useful in relaying messages over vast distances, but it also
helped to identify the sender of the code. Like the identification
techniques used for Morse code, keystroke dynamics can help stem the
incidence of identity theft, and can prove useful in the e-commerce
industry where a lot of highly sensitive personal information is
transmitted online.
Some companies, even Payza, are still making use of the
username/password credential system and have no immediate plans to adopt
a biometric means to authenticate our users, but it is still exciting
to know that such avante-garde and highly feasible means for identifying
people are on the horizon.
In the mean time, you can strengthen your passwords by making use of programs like Password Safe (
