May 2002 Access Control & Identity Management

LG Electronics recently launched an access control system based on iris recognition, the IsisAccess 3000.

Iris recognition technology identifies people by the unique patterns of the the iris of the eye is the most personally distinct feature of the human body. Its details remain stable and unchanged from one year of age through life. In the entire world population, no two irises are alike in their mathematical detail, even among identical twins.

How it works

The characteristics of the iris are acquired during a brief enrollment by simply looking into an ordinary digital camera. A 512-byte digital code is derived from these characteristics and stored for later comparison. Subsequentially, glancing into the camera positioned at an access point, matching patterns is found in realtime image against the enrolled IrisCode make identification within less than 1 s. Eyeglass, contact lenses or even sunglasses have no effect on the identification.

System configuration

The system consists of an Enrollment Optical Unit connected to a central PC/server, four remote optical units are accommodated on an identification control unit which in turn is interfaced to the server on TCP/IP network. A total of 128 remote optical units can be connected to one server.

Worldwide acceptance

Since the introduction of IrisAccess this year, the system has been installed in a number of airports such as Schipol, Heathrow, Dallas, Cheriotadale and the Pentagon.

Telbit Electronics, the distributor of IrisAccess in South Africa is targeting the system at security and access control companies, system integrators and installations of high security profiles such as airports, government, the army, hospitals, etc.
