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.
随着数据和身份盗窃变得越来越普遍，市场对生物测量技术（如指纹扫描）的需求不断增长，这些技术可以防止他人进入私人电子空间。然而，目前这些技术仍然很昂贵。

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.
佐治亚理工学院的研究人员表示，他们已经想出了一种低成本的解决方案：智能键盘。这款智能键盘可以精确测量人们打字的节奏以及手指对每个键施加的压力。通过分析用户的打字力度和按键之间的时间等模式，键盘可以提供强大的安全层。这些模式对每个人来说都是独特的。因此，键盘可以确定人们的身份，并且可以推断出是否应该允许他们访问与之连接的计算机——无论某人是否正确输入了密码。

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.
它也不需要人们不熟悉的新型技术。每个人都使用键盘，每个人的打字方式都不同。

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.
在描述这项技术的研究中，研究人员让100名志愿者使用智能键盘四次输入单词“touch”。从设备收集的数据可以用来根据参与者的打字方式识别不同的参与者，错误率非常低。研究人员表示，这款键盘应该很容易商业化，主要由廉价的类似塑料的零件制成。团队希望在不久的将来将其推向市场。
