Having problems with "shoulder surfers," those people who hover around you while you're typing your password? At Oracle OpenWorld Fujitsu Computer Products of America will be showing off its new PalmSecure LogonDirector that uses a person's unique palm vein pattern for security. The technology embeds highly accurate biometric identification technology in a mouse that uses near-infrared light to capture a person's palm vein pattern. That generates a unique biometric template that's matched against a palm-vein pattern record stored in an encrypted repository.
