美國大學開發人造指紋 能解鎖全球1/3手機

Artificial fingerprints have been developed by researchers who say they could one day be used to hack into everyday devices.

研究人員於日前開發出了人造指紋，並稱其未來將可被用來解鎖日常設備。

Researchers from New York University and Michigan State University successfully generated what they call "DeepMasterPrints".

紐約大學和密歇根州立大學的研究人員成功開發出了“深度學習指紋”。

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

研究人員稱，這種基於機器學習的算法相當於一把“萬能鑰匙”，有潛力解鎖約1/3的受指紋保護的智能手機。

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

研究人員在接受消費者新聞與商業頻道電話採訪時表示：“手機和許多其它設備並沒有捕捉到你的全部指紋信息。因爲設備存儲空間有限，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 sensors from devices' buttons to screens, allowing them to pick up higher resolution images.

許多開發者已經開始通過將感應器從設備的按鍵轉移到屏幕，讓其採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're convenient but less secure," the researchers said. "Their sensors only register a quarter or so of the fingerprint's features."

研究人員表示：“一些智能手機的側邊按鈕上有非常薄的感應器，這雖然很方便，但不太安全。它們的感應器只記錄了指紋特徵的四分之一左右。”
