Iris recognition technologies verify the identity of authorised persons by relying on the complex and intricate patterns in the iris of the eye, the plainly visible coloured ring surrounding the pupil. Iris patterns become stable at 3 years of age, and do not change throughout the lifetime of an individual, making them ideal for authentication purposes.
A detailed image of the iris of each authorised person is entered into the system, which is transformed into a pattern map and stored securely using 3DES encryption within the system’s database. This process involves little more than taking a digital image – no bright lights, lasers or hazardous emissions are involved, and no physical contact is made between the control station and the individual.
Verification of identity occurs by an individual simply looking into an imaging device at an access control station. The system compares the captured pattern map against those of authorised individual's held on record - if there's a match, the identity is verified.
The primary benefits of Biometric technologies are the greatly increased levels of accuracy and the reduction in vulnerability to false authentication. However, with no keys or cards to produce or replace, and no physical contact involved in authenticating, the costs of administration and maintenance are also much lower than with conventional authentication methods.
Additionally, no attendants are required to operate the control station as the system provides instructions to approaching individuals in up to 14 different languages to guide them through the verification process. Tamper detection alarms within these stations mean security staff monitoring in remote locations can be altered to attempts to circumvent the system.
Combining these low maintenance requirements with the ability to accommodate growing numbers of users (licensing options range from 100 to 5000 users and above), makes IES Biometric solutions truly scalable, allowing for numerous control stations to quickly process thousands of users with a minimal level of human intervention.
