1. A system, comprising:
a processor that executes computer-executable instructions stored in a computer-readable memory, wherein execution of the computer-executable instructions causes the processor to:
superimpose a box on a video being presented on a client device, wherein the video is a live video of a space in front of the client device;
set, based on a determination of a location of a face in the video, a location of the box within the video that causes at least most of an image of the face to be outside the box prior to the image of the face moving to a location inside the box;
define a flash pattern as a series of bright and dark flashes;
in response to determining that the image of the face within the video has moved to the location inside the box, capture a sequence of frames of the video while controlling an amount of illumination cast into the space in accordance with the flash pattern, wherein the sequence of frames is captured after the image of the face has moved to the location inside the box and while the image of the face remains within the location inside the box; and
output, after the capture of the sequence of frames, a liveness verification result based on an analysis of the sequence of frames.
