It sounds sophisticated to a layman, but I have doubts over its practicality. For example, how will the system overcome image noise introduced by traditional dressing, such as the keffiyeh and hijab? I'm no expert, but have played around with haar face detection, and eigen/fisher face recognition. My experience was that factors like face position, facial adornments (caps, spectacles, moustaches, etc) and ambient lighting had significant effects on accuracy. There was also the reported failure of face recognition in the Boston marathon bombing investigation [1].
