Two men were sitting together in a plane. They were on a long journey. One of the men was a businessman. The other was a farmer. They sat without talking for a while, then the farmer said,“Let’s do something to pass the time.”

“What do you want to do?” the businessman asked. “We can ask each other riddles.” The farmer said,“You start.”“Let’s make the rules first,” the businessman said. “That’s not fair. You are a businessman with much knowledge. You know more things than I do. I am just a farmer.”

“That’s true.” The businessman said. “What do you want we should do?” “If you don’t know the answer to a riddle, you pay me $100. And if I don’t know the answer, I’ll pay you $50.” The farmer said. The businessman thought about this, then he said, “OK. That’s fair. Who will go first?”

When you're surfing the Internet on your laptop from your dorm or home, do you know your personal details are being gathered secretly? And would you be surprised to know the information may be sold cheaply to advertisers and marketers?

According to an investigation by The Wall Street Journal, all it takes is a tiny file in a computer-a single code consisting of a long series of numbers and letters-to record the computer user's age, gender, location, favorite movies and hobbies.

The newspaper reports that Lotame Solutions Inc., a New York company, uses an advanced software called “beacon” to capture what people are typing on a website.

Lotame packages that data into profiles (个人资料) about individuals, only without their names, and sells the profiles to companies seeking customers. Batches of such data may be sold for a few dollars.

The Wall Street Journal survey discovered that spying on Internet users is one of the fastest?growing businesses on the World Wide Web.

The “cookie”-a tiny text file put on your PC by websites or marketing firms which might be used to remember your preferences for one site, or to track you across many sites is already old news. There are new and more complex tools such as “beacon” which scan in real time what people are doing on a webpage. These beacons instantly assess the Internet user's location, income, shopping interests and even medical conditions.

Millions of Internet users around the world also face unprecedented (空前的) threats. Private, sensitive, personal and business information is being gathered and sold without their knowledge.

Companies insist the information they gather is anonymous(匿名的) and the data is used harmlessly. But the technology has grown so powerful that even some of the biggest websites in the US don't know that they were installing intrusive files on visitors' computers. These include MSN.com and Yahoo.com.

Next time you visit a webpage and find an ad banner advertising something you've been planning to buy, don't be amazed that your computer can read your mind.
