IRIS PRO WEBCAM CODE
If the code matches one of the codes entered in the database, the person is positively identified. It starts the procedure for comparing hundreds, thousands, or even millions of iris codes available in the database. The system quickly analyzes the resulting image, extracting an iris code from it. The person stands in front of an iris scanner connected to the database and goes through a quick re-photographing of the eye. Once the iris photo has been entered into the database, your identification process will be easy and hassle-free. Stage 2: Confirmation of the Authenticity of the Eye Taking a picture of your eye is completely automatic and does not take more than a few minutes. These two digital photographs, taken under different types of lighting, are then subjected to computer analysis, which removes unnecessary details (such as eyelashes) and highlights about 240 features in iris patterns (approximately five times more «features to compare» than used in fingerprint identification systems).Īfter that, all found unique characteristics for each eye are converted into a simple, digital number consisting of 512 digits (also called an iris code), which are stored in the computer database along with your name and other details. Infrared light in the iris scan helps to recognize the unique pattern of darker eyes more accurately, which is more challenging to do in normal light. In this case, the photographing procedure takes place under standard lighting and invisible infrared – the latter is a type of light used in night vision devices that has a slightly longer wavelength than ordinary red light. Therefore, to launch this scenario, each person must go through one-time photographing of their eyes. This means that there are two stages in scanning the iris of the eye: Stage 1: Taking a Snapshot of Your EyeĪll that such a recognition system needs to verify a person is a snapshot of his iris. The unique iris pattern must be recognized to pass such a biometric scan, allowing an identification response. Proponents of the technology claim that iris recognition will very soon become the mainstream identification technology in various fields. The cost has always been the most significant deterrent to technology adoption, but iris identification systems are becoming more affordable for various companies. In comparison, the best fingerprint recognition identification systems use 60-70 points.

Iris scanning software uses about 260 anchor points to create a sample. The iris' texture resembles a network with many surrounding circles and patterns that can be measured by a computer. The term «scanning» can be misleading, as the process of obtaining an image is not scanning but simple photographing. The camera can be installed at a distance of 10 cm to 1 meter, depending on the scanning equipment. As long as the eye has an iris, its host can be identified. A blind person can also be identified using the iris of their eye. It should also be noted that the performed operations on the eyes, removal of cataracts, or implantation of corneal implants do not change the iris's characteristics it cannot be altered or modified. Glasses and contact lenses, even colored ones, will not affect the imaging process in any way. It is impossible to find two completely identical patterns of the eye's iris, even in twins. Scientists have conducted several studies showing that the human retina can change over time while the iris remains unchanged. In the early 90s, John Duffman of Iridian Technologies patented an algorithm to detect the iris of the eye. According to the theory of probability, in the entire history of mankind, there have not yet been two people with the same iris. The probability of its coincidence is about 1078, which is much higher than with fingerprinting. He stated that each person's iris is unique. Iris scanning technology was first proposed in 1936 by an ophthalmologist, Frank Burch. Iris authentication technology is believed to have evolved from another very well-known technology, retinal authentication. Which Is More Common: Retina or Iris Scanner? Why Is an Iris Scanner Unique Technology? What Is an Iris Scan? Definition & Meaning In this article, we’ll cover how the technology works, a comparison of the iris and retina scanning, and the prospects for the future of iris recognition. Such identification reduces the risk of failure of facial recognition systems. Artificial intelligence makes this technology more accessible for use in CCTV cameras, smartphones, and other access and security controls. Iris recognition is an innovative and secure biometric authentication method.
