The IrisAccess System from LG Electronics is a biometric identification system based on iris recognition. The iris is the human body's most unique characteristic and is not influenced by genetic inheritance (DNA). The possibility of finding two identical irises lies in the order of 1:10⁷⁸. By comparison, the current world human population lies in the range of 1:10¹⁰. A further advantage is the fact that the structure of the iris is determined by the eighth month of pregnancy and remains unchanged until death.

Identification is carried out by a non-intrusive quick look (1 - 2 seconds) into the lens of an integrated camera in the optical unit. The decisive parameter is the structure, not the color of the iris. Eyeglasses and contact lenses have no influence on the identification process nor do classical eye diseases, such as cataracts, glaucoma, etc.

An integrated proximity sensor automatically initiates the system on approach. System operation is made very easy by the use of automated speech guidance. Due to the camera technology employed, the application is completely non-hazardous to health. Many applications in the security and high-security fields can be implemented with the aid of an IrisAccess System. Moreover, a large range of applications can be addressed through the combination with other state-of-the-art sensor techniques.

The system is network capable, supports standard SQL database systems and can be customized or integrated into existing structures through software engineering. Loss, theft or failure to remember access cards, transponders, PIN codes or passwords belong to the past. "Borrowing" the access rights of another is no longer possible.

Harmless
There is no harm in exposing your iris to the optical units while the video picture is being taken. Capturing the iris image is just like taking a picture. The level of radiance from 2 IR LEDs in the optical units meets the US and the European eye safety standard.

Convenient Operation
Only your iris is required for registration and recognition. The identification process can be performed accurately, regardless of wearing eyeglasses, sunglasses, soft contact lenses or having sore eyes.

Non-Contact
The iris image can be fully captured within a comfortable distance of 3”-10” from the optical unit, which does not require any bodily contact.

Accuracy
The fundamental operation of a biometric system is the comparison of a captured image against pre-memorized data. The False Match Rate measures the accuracy of the matching process. The False Match Rate of an iris recognition system is nearly 0%.

Expense Curtailment
Once the system is installed, there are no additional expenses for registration. A single ICU3000 can control up to four ROU3000s installed adjacent to four doors.

Strengthening Current Security
By integrating an additional IrisAccess3000 into the existing Access Control System, disadvantages existing in the current system can be compensated for, as well as, higher security levels can be achieved within security zones with minimal effort.

Scalability
The IrisAccess 3000 can handle databases with multi-million entries without negatively impacting the accuracy of the System.

Easy Registration
After installing the enrollment software on the Client PC, registration can be completed within 1-2 minutes and just a few mouse clicks.

Speedy Identification
Identification can be performed within just 1 second.

IrisAccess3000 Components

EOU3000
The EOU3000 is placed on a desk or table adjacent to the Client PC. The EOU3000 contains all the elements necessary to initiate the enrollment process, illuminate the iris and aquire an iris image. Usage is made easy through voice guidance and optical indicators.

ROU3000
The ROU3000 is installed adjacent to the door being controlled. The ROU3000 is composed of 2 parts, an optical imager with the front enclosure and the rear enclosure. After the rear enclosure is mounted on or recessed into the wall adjacent to the controlled portal, the optical imager with the front enclosure is mounted within the rear enclosure. The ROU3000 contains all the elements necessary for iris image acquisition. Usage is made easy through voice guidance and optical indicators informing the user of identification or dismissal.

ICU3000
The ICU3000 is installed on the wall inside the protected area in order to discourage tampering with the computer. The ICU3000 generates an IrisCode based on the iris image input from the ROU3000 and compares it with the pre-memorized iris records. If an IrisCode match is found, the ICU3000 generates a signal to open the door. Basically, the ICU3000 can control the access of two doors through installing one Frame Grabber Board (FGB) and one Door Interface Board (DIB). By installing an additional FGB and DIB, the ICU3000 can control up to four ROU3000s, namely the access of four doors.

FGB3000
The Frame Grabber Board FGB3000 is installed in the Client PC and in the ICU3000. This card records the video images of the iris and pre-codes these images for generating the IrisCode.

DIB3000
The Door Interface Board is installed in the ICU3000. It contains connections to control the camera's ROU3000, as well as, various in/outputs necessary to control the doors or communicate with other systems. In Addition, a connection to a Wiegand card reader (for verification mode) is possible.

Server/Client PC
The Server PC can serve as Super Server, Server, Enrollment Station, Monitoring Station or Management Station. These functionalities can be performed both from one PC or various PCs.

• The Super Server transfers database records from one Server to the other upon request.

• The Server manages Management Stations and ICUs.

• The Enrollment Station performs the iris registration with the EOU3000.

• The Monitoring Station monitors the status of ICU, ROU, EOU and doors being controlled.

• The Management Station not only maintains the old and new database of users, but also allows downloading of necessary data to the ICU3000.
