摘要：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 authenticateduser's image using a picture of the user. Implementations disclosed herein utilize time offlight and/or reflectivity measurements of an authenticated user to compare to suchvalues obtained for an image of an object. If the time of flight distance and/or reflectivitydistance for the object match a measured distance, then the person (i.e., object) may begranted access to the device.
