问题     Bill Gates may be one of the smartest guys in the country, but
even he’s annoyed at having to remember a sort of personal
passwords for activities like withdrawing money and going online.
He also thinks they’re secure. At last week’s Comdex computer【S1】______
convention in Las Vegas, the Microsoft CEO railed the password as【S2】______
a " weak link". One of his proposed solutions are biometrics, the【S3】______
measuring of unique characteristics like the fingerprints and the iris
of the eye for the purpose of verifying identification.【S4】______
    That delighted about the dozen or so companies that brought【S5】______
biometric technology to Comdex. Mostly start-ups, they came to
Vegas shopping schemes to identify you in your hands, your eyes,【S6】______
your voice, even the way you type. " We want to see a biometrics
row in every CompUSA, right next to joysticks and printers. " Says
Kevin Corson of True Touch, a maker of software that works with
various forms of the technology.
    Comdex attendants eagerly lined on at the counter of IriScan, a【S7】______
firm based in Marlton, N. J. , to hold a scanner—it looked a bit like
a hair dryer—about three inches from their eyes. The device works
by taking a video image of the iris, breaking the image into circular
frameworks and analyzed the unique patterns within each area. The【S8】______
company says there’s only a one-in-10 chances that two people’s iris【S9】______
will match in its system.
    A company called Identicator, in San Bruno, Calif. , is aiming
a little lower—at your forefingers. The company licenses its
scanners to Compaq and other companies, which combine them with
keyboards and mice or sell them as $100 stand-alone units that you
can put into your computer.【S10】______
【S2】
