It is clearly stated in the passage that ----.

Typing in passwords could be a thing of the past, thanks
to technology that can read your thoughts. A new
discovery brings cognitive biometrics very close to
reality. In cognitive biometrics, the response of your
nervous system to a stimulus is measured, then used to
identify you. A series of letters or images are flashed up
on a screen and your P300 wave – a type of electrical
activity in the brain – is measured using electrodes
attached to your head. When a pre-defined word, letter
or image is shown, recognition by the user generates
their signature, P300 wave. Until now, users have been
shown different letters or symbols in different parts of a
screen. But tests at the universities of Essex and
Wolverhampton have found that the system identifies
individuals most accurately if all characters appear in
the same location. This also reduces the chances of
criminals spotting the brain word by tracking eye
movement. As there is no keyboard involved, it is much
harder for someone intent on fraud to get access to a
password. “You still have to keep your password
secure,” says Dr. Palani Ramaswamy. “It’s just that the
way of entering the password is more resistant to fraud.”
Accuracy still needs to be improved before cognitive
biometrics can come into mainstream use. “Once
accuracy is close to 100 percent, it can be used for
high-security military applications and financial
transactions as well,” he maintains.
