●Face authentication Face authentication is a method for matching face patterns by extracting the features of face parts such as the eyes and nose. Face authentication is performed by requiring the person to stand in front of a camera for authentication, or through automatic authentication as the person walks through a hallway. It is used for applications such as airport check-in and entrance access control, and customer management.
●Retina / iris authentication The“ retina” is a thin lining at the back of the eyeball. Retina authentication involves matching the pattern of capillary vessels in the retina. The“ iris” is a circular lining that adjusts the contraction and dilation of the pupil. Iris authentication involves matching the pattern of the iris. Although there is variance between the left and right retinas and irises on the same individual, it does not change with the passage of time. For this reason, retina and iris authentication are used as a means of entrance access control for confidential areas of government and business.
