2019全国卷一阅读C篇（卢姣华译）
As data and identity theft becomes more and more common, the market is
growing for biometric technologies—like fingerprint scans—to keep others
out of private e-spaces. At present, these technologies are still expensive,
though.
，市场对用于防止他人入侵私人电子空间的生物特征识别技术的需求随之增长——比如指纹识别。不过，目前这些技术还相当昂贵。
Researchers from Georgia Tech say that they have come up with a low-cost
device that gets around this problem: a smart keyboard. This smart
keyboard precisely measures the cadence （/ˈkeɪdəns/ n. 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.
乔治亚理工学院的研究人员说，他们已经设计出可以解决这个难题的低成本仪器：一种智能键盘。这种智能键盘可以精确地测出每个人敲击键盘的节奏以及手指触键的力量。通过分析用户打字的力度和按键的时间间隔，这种键盘可以提供强有力的保护。这些模式对每个人来说都是独一无二的。因此，这种键盘可以确定用户的身份，从而确定他们是否有权进入它所连接的电脑——不管此人有没有正确的密码。
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.
它也不需要用到一项用户不熟悉的新技术。每个人都使用键盘，每个人打字的模式都不一样。
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.
在一项介绍此技术的研究中，研究人员让100名志愿者用这种智能键盘输入“touch”这个单词四次。根据他们的打字模式，从设备上收集的数据可以辨识出不同的参与者，
错误率非常低。研究人员说，此种键盘应该很容易走向商业化。它主要是由廉价的类似塑料的零部件组成。该团队希望在不久的将来将其推向市场。
