Description: Retina scanning is a biometric identification method based on the unique patterns of an individual’s retina. This process involves the use of advanced technology to capture images of the back of the eye, where blood vessels and other details unique to each person are located. Unlike other forms of biometrics, such as fingerprints or facial recognition, retina scanning offers a high level of accuracy and security, as retinal patterns are extremely difficult to forge. The technique is typically performed using a specialized device that illuminates the retina and captures the image, which is then analyzed to extract distinctive features. This method is non-invasive and can be carried out in a short period of time, making it suitable for various applications, from security to healthcare. The growing concern over privacy and data security has led to renewed interest in retina scanning as an effective form of authentication, especially in environments where a high level of security is required.
History: Retina scanning was developed in the 1930s, although its practical use began to take shape in the following decades. In 1976, Dr. John Daugman introduced an algorithm that allowed for the identification of individuals through retinal patterns, marking a milestone in biometrics. Over the years, the technology has evolved, improving the accuracy and speed of scanning.
Uses: Retina scanning is primarily used in security applications, such as access to restricted facilities and authentication systems in electronic devices. It is also employed in the medical field to detect eye diseases and assess the overall health of the patient.
Examples: An example of retina scanning use is in airports, where it is implemented for access control to restricted areas. Another case is in some financial institutions that use this technology to authenticate their customers at ATMs.
