RETINAL SCANNING Meaning and
Definition
-
Retinal scanning is a biometric technology used for identifying and verifying individual identities by mapping and analyzing the unique patterns present in the human retina. The retina, being the light-sensitive layer of tissue located at the back of the eye, contains a complex network of blood vessels that forms a distinct pattern for every individual.
The process of retinal scanning involves the use of a specialized scanner or camera that captures high-resolution images of the retinal blood vessels. This technology employs infrared light to illuminate the eye, enabling the scanner to capture the unique patterns present in the blood vessels. These patterns, also known as retinal biometric templates, are then converted into a digital code specific to each individual.
Retinal scanning is considered one of the most accurate and secure biometric identification techniques due to the uniqueness of retinal blood vessel patterns. It offers an extremely low false acceptance rate and a very low probability of false rejections. Additionally, retinal patterns are highly stable and remain unchanged throughout a person's lifetime, making it an ideal biometric for long-term identification purposes.
This technology finds applications in various sectors, including law enforcement, access control systems, high-security facilities, and healthcare. It provides a reliable and efficient means of personal identification, ensuring enhanced security and preventing fraudulent activities. However, retinal scanning may require the cooperation of individuals and necessitate close proximity to the scanning device, which can sometimes be perceived as invasive.

Etymology of RETINAL SCANNING
The word "retinal scanning" is a compound of two terms: "retinal" and "scanning".
- "Retinal" refers to the retina, which is the light-sensitive layer located at the back of the eye. The retina plays a crucial role in the formation of visual images.
- "Scanning" refers to the process of examining or analyzing something in detail by systematically moving across or through it.
Therefore, "retinal scanning" specifically refers to the process of analyzing or capturing images of the retina in a systematic and detailed manner.
