Electronics manufacturer LG has incorporated biometric technology, which recognises unique human traits such as fingerprints and voice patterns, into a desktop camera.

LG's Iris Access Control system has been integrated into a small (4x7.5x5.8cm) camera which can be connected to a PC via USB (universal serial bus) to provide sci-fi style security in the home or office.

Pricing has yet to be confirmed, but LG recognises affordability is key. "Fingerprinting would be the most secure parameter, but this sort of software is not affordable to the average user," said a spokesperson for LG. "[Iris Access Control] allows the user to enjoy security and affordability."

The company has improved the accuracy of its Iris Access Control system, first introduced back in 1999, so that it can now read an eye within 2.5 seconds from a distance of up to 5m.

Using a built-in frame grabber to scan the iris, the software records a genetic blueprint of the eye - unique information which provides a near-impenetrable security system that can be used to stop an unauthorised person from gaining access to sensitive data on a PC.

"This system allows an extremely high level of security for the user," said LG's spokesperson, "but is extremely easy to use."
