Even among identical twins, whose faces may not be unique enough to distinguish using facial recognition, irises provide individual patterns that are easily distinguishable. Up until now, iris recognition has been less adopted than fingerprint recognition or face, but due to its exceptional accuracy rate, we can expect it to continue to grow in popularity, particularly by governments. Like other forms of biometric identification, iris recognition involves capturing an image and encoding the unique properties approximately features per iris to create a biometric template for searching and matching.
Unlike facial recognition, though, iris recognition requires a specialized digital camera that uses invisible infrared light to capture a high-contrast image of the iris, picking up the unique patterns that are imperceptible to the unaided eye. These cameras can be handheld or mounted for a broad range of use cases. Iris recognition is extremely reliable and highly accurate, making it the method of choice for law enforcement and border control.
However, using fingerprints as a tool for identifying individuals is broadly accepted by most of the public, whereas other modalities, particularly touchless forms, like the iris, can be a harder sell to privacy advocates.
A better application for facial recognition is the ability to exclude individuals from a search to reduce the pool of potential hits, making it a good candidate for multi-modal solutions. When searching large populations, reducing the pool of potential suspects by eliminating certain individuals first, then running biometric matching on the remaining individuals greatly speeds up the process, when timing is critical.
This is ideal for live monitoring of large crowds against a watchlist. Once enrolled, iris recognition is one of the fastest biometric matching modalities on the market, with the ability to handle very large populations with speed. It is also one of the most accurate with one of the lowest rates of false acceptance and false rejection rates. The false rejection rate is a fraction of fingerprints and the false acceptance rate is half what fingerprints are. Iris recognition is nearly impossible to forge or spoof with current technology.
An iris scanner is just a high-resolution digital camera coupled to some sophisticated image-processing software that distinguishes the coloured part of the eye from eyelids, eyelashes and pupil, and compensates for environmental factors. Iris recognition has a much better match rate than fingerprint scanning and is less intrusive than retinal scanning but, like most other biometric scanning methods, it has trouble with live tissue recognition. An iris scan will match against your eye, whether you are conscious or unconscious, live or dead.
Being a highly accurate way of identifying people, there are many advantages of the technology:. Whilst the benefits of Iris Recognition are numerous, there are potential issues to be considered, some of which relate to the technology or to the way the technology is deployed.
Things to consider include:. There are many companies out there who provide Iris Recognition as a biometric authentication solution. NEC has patented the entire process from the detection of the iris from photographed images, extraction of the feature values, matching of features, to noise removal unnecessary parts like eyelashes and eyelids.

How Iris Recognition works The process of Iris Recognition involves the use of a specialised digital camera. This information is then fed through Iris Recognition software where the unique pattern of the iris is analysed and translated to and iris template Iris Recognition is compatible with contact lenses and even eyeglasses and can be used by blind people, as long as they have an iris. Five benefits of Iris Recognition The characteristics of an iris are unique for each individual and even between eyes — your right and left eye both have unique iris patterns.
Being a highly accurate way of identifying people, there are many advantages of the technology: Accuracy — Iris Recognition is one of the most accurate forms of biometric authentication and here at NEC, our Iris Recognition technology has been identified as the most accurate , achieving the highest matching accuracy evaluation in the Iris Exchange IREX IX evaluations performed by the U.
Contactless — whilst proximity to the iris scanner is necessary, Iris Recognition provides a contactless solution which makes it hygienic to use and less intrusive to the end user.
