What is Iris Recognition Technology?
Iris recognition technology is used to identify individuals by photographing the iris of their eye. It falls under a category of technology known as biometric-based authentication, also called biometric security. Iris recognition technology has become popular in security applications because of its ease of use, accuracy, and safety. Its most common use is controlling access to high-security areas. Iris recognition technology works by combining computer vision, pattern recognition, and optics. First, a black-and-white video camera zooms in on the iris and records a sharp image of it. The iris is lit by a low-level light to aid the camera in focusing. A frame from this video is then digitized into a 512 byte file and stored on a computer database. Iris recognition technology is capable of recording this image from as much as 16 inches (40.64 centimeters) away, so no physical contact is necessary. An individual’s identity can then be confirmed by taking another picture of their iris and c
Iris recognition biometric technology positively determines the identity of an individual by capturing a high resolution digital photograph of the individual’s iris. The technology is based on the most mathematically unique biometric — even between twins or an individual’s right and left eyes — the iris of the eye. The technology is non-intrusive unlike other biometric technologies, there is no need to touch anything – thereby eliminating any possibility of transmitting disease, such as SARS, and there are no lasers, strong lights or any kind of harmful beams. By simply looking into the digital video camera (that look and feel like binoculars), a photo of the iris is taken, captured and stored. The iris recognition equipment is portable and simple to use, making it ideal for use at remote locations such as fairs and special events.
