Visiting the Face Recognition Laboratory Room tomorrow

As I'm going to visit the Laboratory Room of a very special person tomorrow, I studied a bit about "Face Recognition", he is now in the most sophisticated position in their field. So, the visitor who is an ignorant like an infant might be very impolite at all. I should know about their field not a little, how much effort was required to come to a now a days situation and what kind of method of recognition are reported till now. I can imagine how much difficulty was overcome to come the situation now.
Probably, would talk about a disguised spay changing some part of face.
The way to do that is not always depended on the change of layout such as that of eyes and eyebrow, nose tip, lip figure, and constructive ratios.
What I could propose about the changing some scaling position, change of upper incisor position by wearing some additional artificial surfaces on the innate anterior buccal surfaces, 2 to 3 mm movement to anterior direction is enough to change into a completely different personality.
Also the change of centric occlusion jaw position to 1 cm higher does the same, aspect ratio change causes a person to be a different person.
The change of the Upper Anterior position and increase of the vertical dimension of centric occlusion are the easiest way of disguise from our professional standing point of view.
Contrary, the accuracy of Face Recognition system would make progress if my proposal about disguise mentioned above is programmed additionally as a variable factor.
We will talk about that tomorrow.
