美國(guó)大學(xué)開發(fā)人造指紋 能解鎖全球1/3手機(jī)

Artificial fingerprints have been developed byresearchers who say they could one day be used tohack into everyday devices.

研究人員于日前開發(fā)出了人造指紋，并稱其未來(lái)將可被用來(lái)解鎖日常設(shè)備。

Researchers from New York University and MichiganState University successfully generated what theycall "DeepMasterPrints".

紐約大學(xué)和密歇根州立大學(xué)的研究人員成功開發(fā)出了“深度學(xué)習(xí)指紋”。

These are machine-learning methods that act as akind of "masterkey" which, the researchers claim, have the potential to unlock about one inthree fingerprint-protected smartphones.

研究人員稱，這種基于機(jī)器學(xué)習(xí)的算法相當(dāng)于一把“萬(wàn)能鑰匙”，有潛力解鎖約1/3的受指紋保護(hù)的智能手機(jī)。

"Phones and many more devices don't capture your entire fingerprint," researchers toldCNBC over the phone. "There's not enough space on the device, so they capture a partialfingerprint -- which is not as secure as the full image."

研究人員在接受消費(fèi)者新聞與商業(yè)頻道電話采訪時(shí)表示：“手機(jī)和許多其它設(shè)備并沒(méi)有捕捉到你的全部指紋信息。因?yàn)樵O(shè)備存儲(chǔ)空間有限，它們只是捕捉了部分指紋，其安全性不如完整圖像。”

Many developers were already making fingerprint scanners more secure by moving sensorsfrom devices' buttons to screens, allowing them to pick up higher resolution images.

許多開發(fā)者已經(jīng)開始通過(guò)將感應(yīng)器從設(shè)備的按鍵轉(zhuǎn)移到屏幕，讓其采集到精度更高的圖像，從而使指紋掃描的安全性更高。

"Some smartphones have the sensors on the side buttons, which are very thin -- they'reconvenient but less secure," the researchers said. "Their sensors only register a quarter orso of the fingerprint's features."

研究人員表示：“一些智能手機(jī)的側(cè)邊按鈕上有非常薄的感應(yīng)器，這雖然很方便，但不太安全。它們的感應(yīng)器只記錄了指紋特征的四分之一左右。”
