As data and identity theft becomes more and more common, the market is growing for biometric（生物測量）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】隨著數據和身份盜竊越來越普遍，市場對指紋掃描等生物識別技術的需求也與日俱增，以防他人侵犯私人電子空間。不過，目前這些技術的價格均十分高昂。

【翻譯】佐治亞理工學院的研究人員稱，他們已經發明了一種低成本的設備——智能鍵盤,來破解這一難題。這款智能鍵盤可以精確測量人們打字的節奏，以及手指施加在每個按鍵的力度。通過分析用戶打字的力度和敲擊按鍵的間隔時間，該鍵盤就能給用戶提供一道強有力的安全防護。由于這些模式對每個人來說都是獨一無二的，因此，鍵盤可以確定人們的身份，并進而決定是否允許他們訪問與之相連的計算機——不管其有正確的密碼與否。

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

【翻譯】在一項介紹該技術的研究中，研究人員讓100名志愿者用這款智能鍵盤輸入“touch”這個詞四次。鍵盤便能利用其所收集的數據、基于不同參與者的打字方式對他們加以識別，其錯誤率非常之低。研究人員說，該鍵盤應該很容易商業化，因為其主要是由廉價的塑料部件制成。該團隊希望在不久的將來將其推向市場。
