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.
随着数据和身份盗窃变得越来越普遍，可以避免外人进入私人电子空间的生物特征识别技术——比如指纹扫描——的市场持续增长。不过，目前这些技术依然昂贵。

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 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宣布已经发明了一种低成本设备解决了这个问题：智能键盘。智能键盘可以精确地测量每个人的打字节奏以及手指按压每个键的力度。通过分析用户打字力度和按键之间的间隔时间，智能键盘可以提供强大的安全保护。这些模式每个人都是独一无二的，因此，智能键盘可以确定人的身份，进而决定是否允许他们访问与其连接的计算机，而不管是否有人拥有正确的密码。

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.
它也不需要一种人们还不熟悉的新型技术。每个人都使用键盘，每个人打字都不一样。

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.
在一项描述该项技术的研究中，研究人员让100名志愿者使用智能键盘输入“touch”四次。从设备上收集的数据可以用来根据不同的参与者的打字方式来识别，错误率非常低。研究人员说，键盘应该很容易商业化，而且大部分是由廉价的塑料部件制成的。该团队希望在不久的将来将其推向市场。
