Retinal biometrics

Human identification that uses retinal biometrics is based on individual distribution of retina vessels

Retina

Retina is light-sensitive surface of the back inner side of eye. It consists of huge number of specialized nerve cells - rods and cones. These cells transfers light rays into neural signals. Cones provide color vision. Rods are more light-sensitive than cones, but provides only black and white vision. Every rod and cone is connected with nerves, whose signals get out of the eye through optical nerve. Optical nerve together with arteria of retina get out of the eye in the special place, where are not any rods and cones, called the blind spot.

Method

Retina is digitalized by special optical IR mechanism. Distribution of retina vessels is evaluated and compared with relevant databases.

Usage

• Time-register/Attendance systems
• Access control systems
• Identification systems
• commercial institutions of all types and sizes
• institutions of state administration
• areas with very high requirements on safety identification, prevention of terrorism

Advantages

• very high responsibility, suitable for areas with very high safety identification requirements

Disadvantages

• scanning by IR optical scanning mechanism
