As
data and identity theft becomes more and more
common, the market is growing for biometric(
生物
测
量
)technologies
—
like fingerprint
scans
—
to keep others out of private
e-spaces. At present, these technologies are
still expensive, though.
Researchers from
Georgia Tech say that they have come up with a
low-cost device(
装置
)that gets around this
problem: a smart keyboard. This smart keyboard
precisely measures the cadence(
节奏
)with
which one types and the
pressure fingers apply
to each key. The keyboard could offer a strong
layer of security by analyzing things like the
force of a user's typing and the time between
key presses. These patterns are unique to each
person. Thus, the
keyboard can determine
people's identities, and by extension, whether
they should be given access to the computer it's
connected to
—
regardless of whether
someone gets the password right.
It also
doesn't require a new type of technology that
people aren't already familiar with. Everybody
uses a
keyboard and everybody types
differently.
In a study describing the
technology, the researchers had 100 volunteers
type the word
“
touch
”
four times
using the smart keyboard. Data collected from
the device could be used to recognize different
participants based on
how they typed, with
very low error rates. The researchers say that the
keyboard should be pretty straightforward to
commercialize and is mostly made of
inexpensive, plastic-like parts. The team hopes to
make it to market in the near
future.
28.
Why do the researchers develop the smart keyboard?
A. To reduce pressure on keys.
C. To
replace the password system.
B. To improve
accuracy in typing
D. To cut the cost of
e-space protection.
29. What makes the
invention of the smart keyboard possible
？
A. Computers are much easier to operate.
