The newspaper reports that Lotame Solutions Inc. , a New York company, uses sophisticated(高科技的) software called a “beacon” to capture what people are typing on a website.

　　Lotame packages that data into profiles 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 “beacons” 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 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.
