Next time you enter a username and password, think about the rhythm of your typing. Not only can it be used to identify you, it can reveal if you are in a stressful environment.
It has long been known that the rhythms of a person’s typing style are【C1】______over time, leading to suggestions they could be used to【C2】______identity or even spot early signs of Alzheimer’s disease. But little was known about the effect of stress on typing【C3】______, so psychologist Mike Dowman and colleagues at the University of Abertay investigated.
They asked 35 people to log into a computer 36 times over three【C4】______sessions up to a month apart, using the same username and password. People were put into【C5】______and relaxed states alternately(交替地)by listening to a range of sounds known to【C6】______particular emotions.
The length of time each key was held down and the【C7】______between one being released and another pressed was recorded to generate a typing "fingerprint" for each person. The team used the data to develop and test software that identifies a person from their typing style【C8】______.
The data also showed that stress can be【C9】______in a person’s typing because it changes the pattern of timings.
"There’s no question: people do type【C10】______under stress," says Dowman. He suggests that security systems could be designed to raise the alarm if it seems that a person might be being forced to log into a system. More research will be needed, however, before a system could tell if a person is, say, just having a bad day or being held at gunpoint.
A)stressed E)interval I)differently M)normally
B)alone F)verify J)environments N)patterns
C)provoke G)only K)detected O)separate
D)stable H)unchangeable L)complete
【C4】
选项
答案
O
解析
此处应为形容词。空后的sessions表示“一段时间”,据下文的the same可推断此处表示“三段单独的时间”,表明在这三段不同的时间里用同洋的用户名和密码,体现实验的合理性。separate符合文意。注意alone作形容词时也有“单独的”之义,但是alone只能作表语形容词,不能作定语修饰名词,故排除。
