Iris Recognition
What is Iris Recognition?
Of all the biometric technologies used for human authentication today, it is generally conceded that iris recognition is the most accurate. Coupling this high confidence authentication with factors like outlier group size, speed, usage/human factors, platform versatility and flexibility for use in identification or verification modes - as well as addressing issues like database size/management and privacy concerns - iris recognition has also shown itself to be exceedingly versatile and suited for large population applications.
But what makes Iris Recognition the authentication system of choice:
  • Stable: the unique pattern in the human iris is formed by 10 months of age, and remains unchanged throughout one's lifetime.
  • Unique: the probability of two irises producing the same code is nearly impossible.
  • Flexible: iris recognition technology easily integrates into existing security systems or operates as a standalone system.
  • Reliable: a distinctive iris pattern is not susceptible to theft, loss or compromise.
  • Non-Invasive: - unlike retinal screening, iris recognition is non-contact and quick, offering unmatched accuracy when compared to any other security alternative, from distances as far as 3" to 10".
Applications:
  • Airports: In high security application the Iris offers accuracy unlike other biometrics systems.
  • Universities: Where user numbers are so high and turn-over of users is frequent Iris provides a cost effective solution. With no cards Iris offers a very economical long term option.
  • Factories: Where people's hands are not always free, or where they could be dirty or wearing gloves hand recognition or finger scan systems are not usually suitable. The Iris provides a perfect solution that is accurate and non-contact.
System Configuration
EOU (Enrolment Optical Unit)

Usually found in a Human Resources or Security department, the EOU is placed on a desk or table and used in a supervised enrolment environment to add the user's Iris template to the system.
ROU (Remote Optical Unit)

The ROU is situated adjacent to the door that is being secured and is the reading decive used to gain access through the door.
ICU (Identification Control Unit)

The ICU Controller is always installed inside a protected or controlled area and directly controls up to 4 x Readers. If an Iris match is found, the unit generates a signal to directly open the door, or provides a Wiegand output to a 3rd party access control system.
  FGB (Frame Grabber Unit)

The Frame Grabber Board captures analogue black and white iris images. It converts the analogue iris image into the digitised format to process in the Server, ServerPC or ICU.
  DIB (Door Interface Board)

The Door Interface Board checks and controls the releasing and the locking of a door associated with a particular ROU. The DIB provides the interface between ROU3 and the ICU and provides a standard Wiegand or RS422 output for use with a 3rd party access controller.
