TECHNOLOGY Iris Recognition Technology

Iris recognition is an automated method of biometric identification, taking unique patterns within a ring-shaped region surrounding the pupil of each eye. It is an extremely reliable and accurate identification method with very low false match rates. However, it has some disadvantages such as requiring specialized hardware equipment.

What is iris and iris recognition technology?

The iris, situated at the front of the eye, is a pigmented, circular muscle that governs the diameter of the pupil, controlling the quantity of light entering the eye to ensure optimal vision. Its function is essential for regulating the pupil’s size, thereby maintaining the appropriate amount of light necessary for clear vision.

Iris recognition technology is a biometric authentication method that identifies individuals based on the unique patterns within their irises, the colored portion of the eye surrounding the pupil which distinguishes it from retina scanning. It relies on high-resolution images of the iris, captured using specialized cameras or scanners, to extract distinct features such as the arrangement of furrows, crypts, and rings. These features are then converted into a digital template, which is stored in a database for comparison during authentication. When an individual seeks authentication, a new image of their iris is captured and compared to the stored templates using pattern-matching algorithms. If there is a sufficient match, the individual’s identity is verified. Iris recognition technology is known for its accuracy and reliability, as iris patterns are highly distinctive and stable over time. It finds applications in various sectors, including border control, law enforcement, access control, and identity management.

What are the benefits of iris recognition?

The benefits of iris recognition technology span various sectors, offering heightened security and streamlined processes. One key advantage is its application in enhancing security measures in public spaces and private institutions like banks, schools, and airports. By accurately identifying individuals based on their unique iris patterns, the technology aids law enforcement in swiftly identifying people of interest, preempting potential threats, and ensuring public safety. Moreover, iris recognition expedites identity verification processes at checkpoints, airports, and borders, simplifying administrative tasks such as banking transactions and workplace access. Its non-intrusive nature makes it a convenient and user-friendly authentication method, minimizing the need for physical contact and reducing the risk of unauthorized access. Overall, the benefits of iris recognition technology encompass enhanced security, streamlined processes, convenience, and personalized experiences across diverse industries and applications.


Brief history of iris recognition

The history of iris recognition technology dates back to the mid-20th century, but its practical application began in the late 1980s and early 1990s. The concept of using the iris for biometric identification was first proposed by ophthalmologist Leonard Flom and engineer Aran Safir in the 1960s. However, it wasn’t until the 1980s that significant advancements in computer vision and image processing enabled the development of practical iris recognition systems. One of the pioneering figures in iris recognition technology was Dr. John Daugman, who developed algorithms for iris recognition while working at Cambridge University in the early 1990s. His patented algorithms, known as Daugman’s algorithms, revolutionized iris recognition and laid the foundation for modern iris recognition systems. Throughout the 1990s and 2000s, research and development efforts continued to refine iris recognition technology, leading to its commercialization and widespread adoption in various applications, including border control, law enforcement, and access control. Today, iris recognition technology continues to evolve, with ongoing advancements in hardware and software contributing to its improved accuracy, speed, and reliability.

How iris recognition technology works

Iris recognition works by capturing a high-resolution image of the iris, which contains unique patterns that are distinct to each individual. This image is typically captured using specialized cameras or scanners designed for iris recognition. Once the image is captured, the iris recognition system analyzes the intricate patterns within the iris, such as the arrangement of furrows, crypts, and rings. These patterns are then converted into a digital template, which serves as a mathematical representation of the individual’s iris characteristics. During the authentication process, when a person seeks access or verification, a new image of their iris is captured and compared to the stored template in the system’s database. Pattern matching algorithms are used to compare the new iris image with the stored template, determining whether there is a sufficient match to authenticate the individual’s identity. If the patterns closely match, access is granted, whereas if there is insufficient similarity, access is denied. Overall, iris recognition technology relies on the unique and stable characteristics of the iris to accurately verify an individual’s identity.

For identification (1:N) or verification (1:1), a template created by imaging an iris is compared to the stored template in a database.


Iris Recognition Technology Standards

The National Institute of Standards and Technology (NIST) is the leading international biometric testing organization and industry-standard developer. NIST is actively involved in developing architectures and conformance test tools to support users that need to comply with selected biometric standards and support product developers and testing laboratories interested in conforming to biometric standards by using the same testing tools available. NIST evaluates iris recognition algorithms in NIST testing:

Innovatrics’ iris identification algorithm is among the best in the NIST benchmarks


Iris is one of the most accurate of the commonly used biometrics. However, only a handful of companies, compared to facial recognition, are providing their own iris identification algorithm for iris matching.

The latest iris identification algorithm from Innovatrics has placed among top 3 vendors both in accuracy and speed in the NIST IREX 10 benchmarks.
