Smartphones can already verify your identity by scanning your fingerprint or your face. But there's something inside you that's also unique proof that you're you.

智能手機可以通過掃描指紋或臉來驗證身份,但同時在你的內心深處,也存在着你自己的特質來證明你就是你。

Researchers have developed a device that uses low-powered Doppler radar to decode the unique geometry of a user's heart…and how it squeezes and swells as it beats. That biometric information can authenticate the identity of the person under scrutiny.

研究人員已經研發了一種設備,利用低功率的多普勒雷達來解碼用戶心臟的獨特幾何形狀,以及當心髒跳動時,是如何擠壓和膨脹的。這種生物特徵信號可以確認審查人的身份。

And if the wrong person sits down: "It would recognize that there is a heart, but the geometry of my heart is different from yours so it would still log me out."

如果錯誤的人入座後,“設備可以識別到有一個心臟,但是所檢測的心臟的形狀和你的不同,所以,我還是無法登陸系統。”

This unusual biometric is robust, because it's actually two different biometrics.

這種不同尋常的生物特徵是很強大的,因爲實際上,這是兩種不同的生物特徵信息。

The first is the shape of your heart -- a 'biologic' biometric or static trait, like fingerprints or iris patterns. The second is the beating of your heart: what's called a 'behavioral' biometric -- which analyzes a dynamic process, and can be harder to spoof.

第一個是心臟的形狀--例如指紋或者虹膜類型等生物特徵或者靜態信息。第二個是你心臟跳動的節奏:也稱爲行爲識別特徵--主要分析動態過程,並且很難作假。

So far they've tested the system on about 100 people -- with an accuracy of over 98 percent. They'll present the results at the MobiCom conference in Utah.

目前爲止,研究人員已經利用該系統測試了約100人--準確度超過98%。他們將在猶他州的MobiCom會議上展示此成果。
