Google的人臉辨識解鎖專利

在Apple取得滑動解鎖的專利後,各家廠商都在設法迴避該專利,記得去年電視上有個Samsung的廣告,一個小孩拿了手機卻無法解鎖,原來是他爸爸有鬍子,而且又秃頭,自己的影像辨識不合,所以不能解鎖。
現在,根據USPTO公告的專利資料顯示:Google剛剛取得了一個人臉辨識技術的專利,該專利將被應用在裝置的解鎖上。
根據該專利說明書敘述,該專利的解鎖方式包含文字密碼或是生物特徵,生物特徵又包含了指紋、視網膜掃描,及人臉影像。

Title : Facial recognition
Filing Date : 2012.7.26.
Issue Date : 2013.3.12.
Abstract :
An example method includes capturing, by an image capture device of a computing device, an image of a face of a user. The method further includes detecting, by the computing device, whether a distance between the computing device and an object represented by at least a portion of the image is less than a threshold distance, and, when the detected distance is less than a threshold distance, denying authentication to the user with respect to accessing one or more functionalities controlled by the computing device, where the authentication is denied independent of performing facial recognition based at least in part on the captured image.
