Dermis / Skin
Skin analysis is one of the latest of biometric technologies. It is new in the sense that until recently, the dermal surface of the skin could not be imaged and classified in an automated manner. Using an algorithm called surface texture analysis, the surface of the skin is analyzed for random features and a skinprint (skin template) is extracted. The skinprint can be used on its own, or fused together with traditional facial or fingerprint biometric systems to deliver exceptional levels of accuracy and robustness. In addition to obvious differences in skin pigmentation, each person’s skin is structurally unique. Skin layers vary in thickness, interfaces between skin layers have different undulations and other characteristics, collagen fibers and elastic fibers in the skin layers differ, and capillary bed density and location differ. Cell size and density within the skin layers, as well as in the chemical makeup of these layers, also vary from person to person.
