Abstract: Facial recognition can be used to determine whether or not a user has access privileges to a device such as a smartphone. It may be possible to spoof an authenticated user's image using a picture of the user. Implementations disclosed herein utilize time of flight and/or reflectivity measurements of an authenticated user to compare to such values obtained for an image of an object. If the time of flight distance and/or reflectivity distance for the object match a measured distance, then the person (i.e., object) may be granted access to the device.
Abstract translation: 可以使用面部识别来确定用户是否具有诸如智能电话的设备的访问权限。 可以使用用户的图片欺骗认证的用户的图像。 本文公开的实施方式利用已验证用户的飞行时间和/或反射率测量值来比较对于对象的图像获得的这些值。 如果对象的飞行距离和/或反射距离与测量距离相匹配,则可以允许人(即,对象)访问设备。

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.
