Face
Our faces make lasting impressions. Despite the growing popularity of cosmetic surgery, research has shown that the face we are born with remains identifiable throughout our lives. The relationships between the parts of the face, its curves and contours, remain relatively stable from childhood onward. Facial recognition techniques use this stability as their point of departure. Facial recognition technologies utilize digital photographs to create mathematical descriptions of individual faces and then compare them against those stored in a database. Facial recognition requires a large image capture device and clear lighting conditions and is therefore most suitable to authenticate identity at fixed locations, such as facility access points. Facial recognition data are also being encoded via mobile technologies, such as the new generation of biometric passports
