Overview on the Biometric Iris Recognition Technology

Iris biometric Reader has been used to analyze the colored part of your eyes and make it as a trait that enables you to identify yourself. Iris is as unique as your fingerprints. In older days, people who failed to have an exact impression of their fingers could not vastly embrace the benefits of a biometric system.

A biometric system is defined as a system that is used for rightly identifying an individual based on his unique physical entities. The physical entity can be specifically one’s voice, fingerprint or face. And more specifically, your iris.

Earlier, Biometrics had changed the entire system of identification. But these days, it is widely used to outlook the attendance entries as well as aids in timing management. The revolution biometrics owns in this contemporary world is remarkable!

Iris Biometric Reader is considered as a great step onto the biometric system, which is equally applicable to all humans. Other biometric traits such as voice or face can get affected for some or the other reason. But the colored part of your eyes is a fundamental spec that can be your sole unique trait for a long time.

Recognition within a blink of your eyes

The recognition of individuals for authentication is valid nowadays. It is always a necessity to have authenticity. The valid authenticity of the individuals forms a crucial part of today’s world at all walks of life.

Know-hows of iris recognition?

Iris scanning biometrics measure the individualistic radii along the colored part of the eye to identify and validate your authenticity. Without any contact, rapid and extremely precise, biometric iris recognition can function at far distances, and delivers accurate solutions that need only a glance from an individual.

How to trace and find iris recognition?

Iris-based identification mandatorily needs specific hardware, unlike software-based entities such as face and voice recognition. Thus, it is not so common in consumer markets and other enterprises. Talking about the factors of cost and installation, iris biometrics is on the edge of huge takeover across the vertical markets also in the consumer electronics infrastructures.

Iris recognition is conventionally employed as a physical access control modality. In an ideal situation that supports high-quality environments with predefined thresholds, speed and accuracy are necessary. Most popularly used as a mechanism in border control sectors It suitably helps us to identify travelers as they enter and exit countries by terrestrial and aerial means of ways.

The latest entry of iris scanners was onto consumer mobile devices. It completely revolutionized the traditional methods of unlocking the home screen.

There has been a huge growth in the Biometric readers in and around Dubai. It takes many tasks to manually identify and authenticate an individual. But in the iris biometric authentication, all it requires is a glance.

To take noble remarks of Iris scanning, we have an honorable mention of a project under development which is the biometric border control pilot project at the Otway Mesa US-Mexico land border. Iris biometrics have been used to safeguard CERN, the scientific embodiment in Geneva, Switzerland, which exudes fame for housing the Large Hadron Collider.

Iris Recognition System

The iris recognition system works by keeping distorted images of iris and stores them as various patterns in a biometric database. Each time the database gets tested with the individual before the screen, the input test data gets cross-checked with the inputs, and if a matching input has is found then the person is identified, and a pass is signaled. Else, it shows a false identity.

A block diagram describes the working of the system:

The majority of the iris recognition systems employ a 750 nm wavelength light source to establish near-infrared imaging. This permits the system to block away from light reflecting from the cornea and effectively produces images that showcase the detailed structure of iris.

But there exists a demerit to this methodology. These images are extremely difficult to find in the identification step. As a result, as of now, visual wavelength imaging is being used over near-infrared imaging.

Iris recognition process consists of three major steps –

Capture the image

The first step starts with capturing the image of the iris of the person whose identity needs to be verified. The image capture by itself can be even manual or automated, but one thing to be noted is, it should be made sure that that the iris is in proper alignment with the focus line and that the image gets captured with high definition clarity.

Iris Location and image optimization

Here, the iris recognition system performs optimization on the focus, and the clarity of the image is enhanced. Later it finds the iris boundaries. Then the center of the pupil is traced, which also acts as the center of the circular iris. Eventually, it identifies the coverage area of the iris image which can be employed for feature extraction and analysis.

Biometric template storage and/or matching

The encoded structural features, or biometric templates, are then stored in the biometric database. It always starts at the point of enrolment of a person. If the iris scan has been done for the authentication purpose, then the biometric template for the scanned image is matched with biometric templates stored in the database.

Advantages of using biometric iris recognition

Various traits of iris that makes it a highly remarkable biometric compared to other biometric traits are-

• Even identical twins have unique irises.
• An iris owns exceedingly 266 degrees of freedom.
• Fingerprints may get tampered with time, but iris is highly protected inside the eyelids and is presumably less susceptible to damage.
• Degeneration of iris with aging does not take place.
• Spectacles or contact lenses will not have any effect on iris recognition and authentication.

“Superiority of iris as compared to other biometric traits.”

Even identical twins have different irises. It is a lucrative option to authenticate an individual using their irises and leave a unique impression. All it requires is just a glance! And the world lays open to you at the very next blink of your eyes!
