Many governments have already used this technology as a highly useful, secure identity management tool.
It is soon expected to enter mainstream commercial sectors such as automotive and mobile communications. As a result, the iris pattern's application is expanding, although its potential is just beginning to unfold.
Each of the leading manufacturers offers scanners in several form factors and can equip large corporations and security agencies with the flexibility to accommodate all their needs. Iris recognition remains one of the most promising biometric technologies for personal recognition. Especially in demand is the realization of the iris' potential for use in non-contact scenarios identification and a face image — and possibly other contactless biometric identifiers.
Therefore, the most relevant research directions are to improve recognition in non-invasive scenarios due to improving sensors, improving the system's informative signs, and integration with other modalities. Of particular interest is the use of the iris in cryptographic applications and secure identification. Eye scan recognition has certain advantages over other biometric technologies that make this technology one of the most preferred mobile devices.
In recent years, several companies have introduced smartphones equipped with iris authentication technology. Biometric authentication is a promising technology that will eliminate the usual authentication schemes using a password.
This will increase the convenience of working with the device, and at the same time, increase the level of protection of personal data. Especially in demand is the realization of the potential of the iris for use in non-contact scenarios identification together with a face image and possibly other contactless biometric identifiers.
When scanning an eye, the pupil region and the iris itself are highlighted. The resulting ring is programmatically cleared of noise and converted into a rectangular format — an iris code, containing information about the object's unique characteristics in black and white like a barcode or QR code.
Then the iris code is compared with the database of registered templates. At the same time, the processing speed is too high, which makes it possible to use the system for working with large databases.
Iris recognition is the most advanced and accurate biometric technology available today, providing precise identification without PINs, passwords, or access cards.
User registration is done in less than 2 minutes. Authentication lasts no more than 2 seconds. Infrared radiation increases the overall temperature of the aqueous humor in the eye, affecting the cornea and aqueous humor. IR-A radiation is absorbed by the retina and is very ineffective in damaging the retina.
Moreover, the image capture procedure is concise and can usually be achieved within seconds. However, in today's biometrics industry, security standards can be ignored. The technology is based on recognition of the iris pattern, and the pattern capture technique, in turn, is based on video recording.
The camcorder does not require bright lighting or close-ups. Iris recognition technology is used to gain access to devices and databases and access buildings, rooms, and apartments. However, the most massive increase in installations of this technology is now observed at the airport.
Various fields of application in iris recognition technologies and targets and objects of injections are presented in the table. Colorless contact lenses are not believed to interfere with iris recognition systems. Contact lenses create significant artifacts in the image and lead to significant degradation of the biometric solution's accuracy.

The retina template generated is typically one of the smallest of any biometric technology. Retinal scan is a highly dependable technology because it is highly accurate and difficult to spoof, in terms of identification. The technology, however, has notable disadvantages including difficult image acquisition and limited user applications. Often enrollment in a retinal scan biometric system is lengthy due to requirement of multiple image capture, which can cause user discomfort.
However, once user is acclimated to the process, an enrolled person can be identified with a retinal scan process in seconds. Retinal scan technology has robust matching capabilities and is typically configured to do one-to-many identification against a database of users. However, because quality image acquisition is so difficult, many attempts are often required to get to the point where a match can take place.
While the algorithms themselves are robust, it can be a difficult process to provide sufficient data for matching to take place. In many cases, a user may be falsely rejected because of an inability to provide adequate data to generate a match template. Because retinal blood vessels are more absorbent of log-energy infrared light than the rest of the eye, the amount of reflection varies during the scan. Retinal scan algorithms require a high-quality image and will not let a user enroll or verify until the system is able to capture an image of sufficient quality.
The retina template generated is typically one of the smallest of any biometric technology. Security equipment is constantly evolving and changing, and increasingly looks more like the props from science fiction films. Offices with high security needs can use retinal scanners to grant employees access to their workspaces or computers. As with fingerprints and iris patterns, genetic factors do not determine the exact pattern of blood vessels in the retina.
This allows retinal scan technology to differentiate between identical twins and provide robust identification. Retinal scanning is also used for medical diagnostic applications. Examining the eyes using retinal scanning can aid in diagnosing chronic health conditions such as congestive heart failure and atherosclerosis. Diseases such as AIDS, syphilis, malaria, chicken pox and Lyme disease, as well as hereditary diseases, such as leukemia, lymphoma, and sickle cell anemia, also impact the eyes and can be detected using retinal scan technology.
Doctors have long used a tool called an ophthalmoscope to look at the back of your eye.
