When Bill Clinton first said, "I never had sexual relations with that woman . . ." back in 1998, a report flushed that a new Israeli lie detector figured he was being truthful.

Looking back on the contradicting outcome, Katsuhisa Katoh, manager of AlphaOmega Soft Co.'s Risk Technology Group, which is affiliated with Israel's Trustech Ltd., defends the tool's reliability: "The software maker's president may have been afraid of making an overstatement because of several ambiguous findings."

Boasting 85 percent accuracy, Truster, lie-detection software made by Trustech, has sold 5 million copies in the West and 20,000 in Japan since its released in early 1998.
