Imagine you went to a restaurant with a date; had a burger, paid with a credit card, and left. The next time you go there, the waiter or waitress, armed with your profile data, greets you with, "Hey Joe, how are you Mary is over there in the seat you sat in last time. Would you like to join her for dinner again" Then you find out that your burger has been cooked and your drink is on the table. Forget the fact that you are with another date and are on a diet that doesn"t include burgers. Sound a little bizarre To some, this is the restaurant equivalent of the Internet. The Net"s ability to profile you through your visits to and interactions at websites provides marketers with an enormous amount of data on you—some of which you may not want them to have.Are you aware that almost every time you access a website you get a "cookie" Unfortunately, it"s not the Mrs. Field"s type. A cookie on the Internet is a computer code sent by the site to your computer—usually without your knowledge. During the entire period of time that you are at the site, the cookie is collecting information about your interaction, including where you visit, how long you stay there, how frequently you return to certain pages, and even your electronic address. Fill out a survey to collect free information or samples, and marketers know even more about you—like your name, address, and any other information you provide. While this may sound scary enough, cookies aren"t even the latest in technology. A new system called I-librarian Alexa—named for the legendary third century B.C. library in Alexandria, Egypt—does even more. While cookies track what you are doing at one site, Alexa collects data on all your Web activity, such as which sites you visit next, how long you stay there, whether you click on ads, etc. All this information is available to marketers, who use it to market more effectively to you. Not only do you not get paid for providing the information, you probably don"t even know that you are giving it. What can be learned about "Alexa" from the second paragraph

On a moremundane(世俗的) level, third-generation mobile telephones, despite all the delays and the billions squandered on 3G licenses by telecom firms, are still expected to offer consumer high-speed, always-on mobile internet access, complete with video, in the next few years. Rapidly proliferating"wi-fi"(无线局域网) networks already offer wireless access on a local basis. Tiny tracking chips called radio-frequency identification devices are being used as passports. Soon they will be small, powerful and cheap enough to be implanted into everything. Sensors of every kind, including video cameras, should also become much smaller and cheaper. Forrester Research, a technology consultancy, predicts that 14 billion such devices will be connected to the internet by 2005.How rapidly such new technology is introduced will depend on a number of factors—the state of the economy, the supply of investment capital and the appetite of consumers for new products or services! Fortunes will be made and lost many times over. But whatever happens, the power of computing and communications looks set to continue to grow, and its price to fall, at a steady rate for the next few decades. That will make it possible, at least in rich countries, to record most human interactions, wherever and whenever they take place, and to store and analyze this ocean of data at low cost.For the sake of argument, this survey will assume that we are heading towards a networked society ofubiquitous(到处存在的), mobile communication capable of constant monitoring. Whether this arrives in 20, 30 or 40 years does not really matter. The point is that the destination seems not merely possible, but probable, so it is not too soon to ask: What do we want this technology to doThe internet has already thrown up a host of legal and political problems, but these are only a small foretaste of the dilemmas—about privacy, security, intellectual property and the nature of government itself—that will have to be faced over the coming decades. The debate has already begun. This survey will outline some of main issues, and speculate on the way they are likely to go. The passage is most probably ______ of a research paper.
