Workers aren't allowed to go into a hugeunderground computer center until they step up to a machine that take a quick picture of the tiny blood vessels(管) inside their eyes.
If the machine can't match thepicture with images in its computer, the worker is stopped by security (安全) guards.
Each person has his own pattern of blood vessels in his or her eyes.And unlike a key, the pattern can't be stolen.
Old--fashioned keys and locks may soon be things of the past.
High--tech security devices(装置) are being fixed at military bases, computer centers, nuclearplants and banks. Companies that make the machines saythey'll someday be used in people's homes an
Already, a Japanese firm has fixed devices that recognize people's fingerprints in 360new homes. The machines open the doors only for the owners of the houses.
The new security devices are selling well because thieves and spies aregetting better at breaking into buildings and computers that are protected by keysand locks. Since nobody cansteal or copy a fingerprint or eye pattern, the new machines are safe .
Other newmachines recognize voice patterns. Two American companies usevoice--recognition machines to keep an eye on their computers.
Inexpensive voice--recognition machines may someday replace locks oncars. The doors would open only for the owners. The devices would cost the owners as little as $ 270.
Although the up--to--date devices area mazing ,scientists must still solve a(n) serious problem.How wi11 a boy borrow his dad's car without borrowing dad's voice?
每个人的眼睛都有独特血管图案,不像一条钥匙,图案不能被窃取。
旧式的钥匙和锁可能很快成为过去。
高科技安全装置正在军事基地、计算机中心、核电厂和银行里安装。制造装置的公司表示,终有一天人们的家也是如此。
目前,一家日本公司已在360户新屋中安装了户主指纹确认仪器。住宅的大门只会为户主开启。
新的安全装置都卖得很好,因为盗贼和间谍的技俩越来越高明,用钥匙和锁作防盗的建筑物和计算机不够安全。新装置则很安全,因为没有人可以窃取或复制指纹或眼睛的图案。
其它的新装置能识别语音模式。有两家美国公司使用语音识别装置来看管他们的计算机。
终有一天,价廉的语音识别装置会取替汽车的门锁,车门将只能被车主打开,这套的装置最便宜的只要270美元。
虽然日新月异的新装置教人啧啧称奇,科学家们仍须解决一严重的问题。一个男孩如何才可借用他爸的车,而不借用他爸的声音呢?
