As data and identity theft becomes more and more common, the market is growing for biometric（生物測(cè)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（裝置）that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence（節(jié)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.

【翻譯】隨著數(shù)據(jù)和身份盜竊越來(lái)越普遍，市場(chǎng)對(duì)指紋掃描等生物識(shí)別技術(shù)的需求也與日俱增，以防他人侵犯私人電子空間。不過(guò)，目前這些技術(shù)的價(jià)格均十分高昂。

【翻譯】佐治亞理工學(xué)院的研究人員稱，他們已經(jīng)發(fā)明了一種低成本的設(shè)備——智能鍵盤,來(lái)破解這一難題。這款智能鍵盤可以精確測(cè)量人們打字的節(jié)奏，以及手指施加在每個(gè)按鍵的力度。通過(guò)分析用戶打字的力度和敲擊按鍵的間隔時(shí)間，該鍵盤就能給用戶提供一道強(qiáng)有力的安全防護(hù)。由于這些模式對(duì)每個(gè)人來(lái)說(shuō)都是獨(dú)一無(wú)二的，因此，鍵盤可以確定人們的身份，并進(jìn)而決定是否允許他們?cè)L問(wèn)與之相連的計(jì)算機(jī)——不管其有正確的密碼與否。

【翻譯】它也無(wú)需什么人們不熟悉的新技術(shù)。每個(gè)人都使用鍵盤，每個(gè)人的打字方式也都與眾不同。（這就夠了。）

【翻譯】在一項(xiàng)介紹該技術(shù)的研究中，研究人員讓100名志愿者用這款智能鍵盤輸入“touch”這個(gè)詞四次。鍵盤便能利用其所收集的數(shù)據(jù)、基于不同參與者的打字方式對(duì)他們加以識(shí)別，其錯(cuò)誤率非常之低。研究人員說(shuō)，該鍵盤應(yīng)該很容易商業(yè)化，因?yàn)槠渲饕�是由廉價(jià)的塑料部件制成。該團(tuán)隊(duì)希望在不久的將來(lái)將其推向市場(chǎng)。
