2.1.5. Ocular-Based Methodology

The iris recognition techniques are on the market for more than 20 years. This approach does not require the user to be close to the capture device while analyzing the color pattern of the human eye. Retina analysis is another attractive technique. Here, a thin tissue composed of neural cells that are located in the posterior portion of the eye is captured and analyzed. Because of the complex structure of the capillaries that supply the retina with blood, each person’s retina is unique. The most prominent challenges in those methods are the need for high quality capture device and robust mathematical technique to analyze the image.
