Typing your password or credit card number into a computer is a moment’s work. But if you think your personal details disappear as soon as you hit the Return key, think again: they can sit on the computer’s hard disk for years waiting for a hacker to rip them off.
As people spend more time on the web and hackers become more sophisticated, the dangers of storing personal information on computers are growing by the day, security experts say. There are some safeguards, such as never allowing your computer to store your passwords. But even that is no guarantee of security.
When you type in a password, it is stored in random access memory (RAM), where it is held temporarily until other data overwrites it or the computer is switched off.
But every so often, the computer copies the contents of its RAM onto hard disk, where it is easy prey for a hacker, who can read it directly or design a worm to e-mail it back. The longer sensitive data stays in RAM, the more likely it is to be copied onto the disk, where it stays until it is overwritten—which might not happen for years.
Tal Garfinkel and colleagues from Stanford University have created a software tool which simulates the workings of a complete computer system. Within the simulation, sensitive data can be tagged and then tracked as it passes through the system. Next, Garfinkel and his team simulated computers running common software that regularly handles passwords or confidential personal information, such as Internet Explorer, the Windows login script and Apache server software.
In a paper to be presented, they conclude that the programs took virtually no measures to limit the length of time the information is retained. Some of the tested software even copied the sensitive information, apparently without restraint.
This is the first time anyone has tried to measure the extent of this problem, says Rebecca Wright, a security expert at Stevens Institute of Technology. Garfinkel hopes the results will arouse software developers to take action.

When I was four years old,I broke my elbow. After many weeks in a cast (石膏) I returned to the hospital to finally have it removed. My mother found it strange that I was so enthusiastic about returning to the place where I had experienced so much pain. Yet she soon discovered my fascination with the healing process and how doctors helped to enhance it.
I was in fear as the doctor removed my cast and asked me to move my arm,and immediately became scared as the pain came shooting back through my elbow. After another series of X-rays and examinations my arm was put into a new cast I had begun to doubt the reliability of the doctor,and my mother thought I would be unwilling to return a second time.
When the day came to have my cast removed again,I was nervous. Yet I was optimistic enough to trust the doctor as he once again removed my cast and asked me to move my arm. And this time it was better! Nothing hurt!
On the way back home I released (松开) my mother's hand and ran ahead,and out of her sight. She was immediately worried that I would come upon someone dangerous. At the age of four I was already known for liking to talk with strangers that I felt were potential friends. When she caught sight of me again, I was looking up into the face of an old broken-legged man,saying,“Don't worry,sir! The doctor will fix your leg. Look how he fixed my arm!”
Since then I have continued to be fascinated with the human body and medicine. I also still love to help people,and never miss an opportunity to encourage someone. But most of all,I still believe that optimism and trust are the building blocks of happiness and success. Many things can change,but I am proud to say that these parts of me have always stayed the same.

A. the hospital seemed like a more frightening place B. the doctor there was unskilled
C. he was afraid of the pain D. he was sure his elbow wouldn't recover

A. That he would break his elbow again.
B. That he would run down others and break their legs
