Iris Scanner & Recognition: Physical biometrics has been making use of various physical traits of human body, including fingerprints, hand geometry, vein structure and so on. A relatively new and comparatively accurate concept employed in this direction is that of iris recognition. The biometric samples are captured using a device called iris scanner, which is a sophisticated piece of modern technology. With all good advantages, these products are surpassing other biometric products.
Features of Iris Scanner
* Iris scanner employs a specialized camera, which emits infrared rays to capture the image of iris.
* The process of capturing the image takes only 2-3 seconds.
* Iris recognition works on the fact that iris structures are more complex than any other physical trait used for physical biometrics. Thus, every template in the biometric device is unique, leading to fast identification and recognition.
* Iris reader makes use of specific algorithms, which are not found in other biometric devices and thus, offer a higher performance level.
Applications of Iris Scanner
* Border-crossing security agencies employ iris scanner for foreigners to stop illegal immigrations.
* E-passports also utilize the concept of iris recognition, along with fingerprint analysis and face recognition.
* For their fast and accurate results, these devices are also being employed as part of airport security systems.
* Residential security is also considering the use of iris reader to provide protection against thieves and housebreakers.
Advantages of Iris Scanner
* Iris recognition devices are advantageous due to the fact that iris is one human body part, which is less prone to damage, as compared to fingers, hands and other parts used for physical biometrics.
* Device used for iris recognition promise zero percent false rejection rates as against fingerprint scanner, which offer 3 percent of this rate.
* The process of scanning iris is simple and similar to that of taking a photograph.
* There is no safety issue related to scanning of iris, as the technique is successfully employed in various parts of the world.
* Iris reader is hygienic to use, as the person is not required to touch any device, already used by different users.
* Iris templates can be preserved for longer than any other biometric samples collected using physical biometrics.
Iris scanning targets the ultimate aim of developing biometric technology and that is enhanced security. With low-cost employment and other great advantages, the biometric iris devices are winners for every type of organization.
