If you have heard about face recognition technologies being implemented in the past few years or so, the emerging phenomena as of now is Iris Recognition. Iris recognition, as the name suggests, is a form of biometric recognition technology that captures an image of a person’s iris.
Iris recognition goes a step ahead in recognition, as compared to other forms of biometrics such as fingerprint scanning. Unlike fingerprint scanning, it is nearly impossible for an individual to tamper the iris or change its properties. Countries have begun to implement iris recognition technology at major access points such as airports to enhance security.
How Does it Work?
Iris scanning is the process of scanning unique patterns in an iris, which are distinct for every individual. There more than 200 unique features in every eye, making iris one of the most difficult biometric to be replicated or forged. The image of the iris is flattened to extract these patterns, and to allow for the comparison of the image with the existing images in a database. These properties are not visible to the naked eye and required specific hardware that can capture such high quality, detailed images of the iris. Anything that blocks any part of the iris is excluded by the hardware including reflections, eyelids and eyelashes. Read more on Iris capabilities here.
The Hardware
Iris scanning devices are small, portable devices that can be installed anywhere, just like security cameras. Their application is most widely applicable at a standard human eye level. It allows an individual to conveniently pass through an access point, without needing much interaction with the device. Advanced Iris hardware is designed to minimise human effort, and conveniently capture the image of a person’s iris on-the-go. The focus is on creating a seamless process which ensures quick identification/verification at busier locations such as airports.
The Application
Iris recognition has several applications, with the most commonly applied by the U.S military to recognise and identify detainees in Iraq & Afghanistan. A portable device, called the SEEK II was used to by the U.S personnel to scan biometrics. The usage in such a scenario remains debatable, but the ethical use of such technology can significantly enhance security efforts.
In 2010, the NYPD also employed biometric scanners in jails. The accuracy of iris recognition was then questionable and hence the use was made voluntary instead of mandatory. In 2015, there were growing plans of using iris recognition in L.A and some other states.
In 2023, governments have realised the potential of biometric technology and have found a way to use it ethically. Security companies such as airport security go through a rigorous process of data protection and compliance to ensure that the data stored is not misused or provided to any third parties.
The Future of Iris Recognition
As the world prepares for a new era of generative AI and information technology, there is a need for robust security methods. Iris recognition service providers are now working towards creating a robust system that can recognise individuals from a distance. For instance, if you’re walking into immigration, your iris could recognise you from 30–40 feet away and allow you seamless entry.
Similarly, it has major application in law enforcement. To reiterate, iris recognition could become the most secure method of verification because of its unique properties. Face recognition is also being spoofed by the use of ultra realistic masks and deepfakes, but iris could be the solution towards a spoof proof recognition technology.
