Abstract
An input device includes multiwavelength reflectance spectroscopic (MWRS) hardware having a first field of view (FOV) and one or more cameras with respective FOVs that differ from the first FOV. The one or more cameras are used to obtain image data. When a hand is determined to be at a specified position within the first FOV and in a specified pose, the MWRS hardware is operated to obtain intensity data. The intensity data is processed to determine liveness data indicative of whether an object in the first FOV is an actual user or an artifact. The image data obtained within a specified time interval relative to the acquisition of the liveness data indicative of an actual user may then be processed to identify the user. Additional assessments may be performed to validate the image data, such as confirming continuity between acquisition of the liveness data and the image data obtained.
