silmäskanneritunnistus

Silmäskanneritunnistus, also known as iris scanning or retinal scanning, is a form of biometric identification that uses the unique patterns of the iris or retina of the human eye for verification. The iris, the colored part of the eye, has a highly complex and random pattern that remains stable throughout a person's life. Retinal scanning, on the other hand, maps the unique pattern of blood vessels at the back of the eye.

The process typically involves a specialized camera that captures an image of the eye. This image is then processed to extract unique features, which are converted into a digital template. During authentication, a new scan is taken, and its features are compared to the stored template. If there is a sufficient match, the individual is identified or verified.

Silmäskanneritunnistus is considered one of the most accurate biometric technologies due to the distinctiveness and stability of the iris and retinal patterns. Its applications range from high-security access control in government facilities and data centers to border control and personal device authentication. While generally reliable, factors like lighting conditions, eye conditions, and the quality of the scanning device can influence accuracy. The technology is also subject to privacy concerns regarding the collection and storage of sensitive biometric data.
