Forensic Optometry The use of iris identification of missing children
The crime you have in your favorite action movies or having a character to enter a secret room, the approach of a car, look inside, and his eyes scanned to see ensure access. The technology used is called the iris identification. But this technology really is? This technology is reliable? The answer to both questions is yes! Iris is a method of identification number, the model of biometric authentication and image recognition technology used to distinguish the characteristics of a person’s eyes. The purpose of the iris recognition software is an almost immediate recognition exact identity of a user process on the scanned digital each individual is based recovery. While some biometric systems can be up to 60 unique characteristics, identification technology, the iris are only 266 points (including ribbons, furrows, ridges, rings, freckles and collarets) used, further analysis of each of the features and the ‘ user identification. As the number of points on an analysis of samples that produce identification iris recognition technologies, so that a high degree of uniqueness holds fingerprints, offers a high probability of identifying the user.
Recognition software, which uses small cameras with HD images of near-infrared (NIR) to create richly detailed reproductions of the iris. When the scan is captured, the iris is the connective tissue (trabecular meshwork) is processed and creates a “visual effect” that in a digital code that is unique to each user based on the characteristics translates the visual impression. The digital code to be recognized by the software to identify a user for processing.
A major advantage of identification technology is the stabilization of the diaphragm and the lives of employees of the scanned areas. No significant trauma to the eyes of a person, not features and model of each eye is not a point where recognition will be affected vary, provided that an indicator may be difficult to reproduce for the identification of all life. The scanning process, while the user can also wear glasses or contact lenses and is less invasive than other biometric identification systems, that the process simple and easy to use.
Because of the uniqueness of each sample, such as identification programs for children and the location of the database (child) Optometrists encourage parents to talk to the identification and registration of the iris of their children in a national database that led to the CHILD project. A model of child iris recognized and registered in a national database to identify the law is able to locate a missing child in seconds and the return of children to their families.
