　　Most of us would shy away from making purchases in a foreign country ff we didn't know the exchange rate. Yet, ff privacy is the true currency of the Interuet, as many argue, millions of us are doing that very thing every day. i Meanwhile, Internet giants amend their privacy policies in ways that allow them　to harvest and sell even more of our personal data. While privacy campaigners protest, users generally vote with their clicks and carry on regardless.

　　So should we conclude the Interuet generation is happy to trade its privacy for free or cheaper Web services? Not according to Nicola Jentzsch of the German Institute of Research in Berlin, and colleagues, who last week published research showing that most people prefer to protect their personal data when given a choice and that a significant proportion are willing to pay extra to do so.

　　The researchers directed 443 students to a website offering tickets for a real movie showing, sold by two different uendors (商販). Although the tickets were subsidized, the volunteers, who were able to purchase one, two, or no tickets, had to pay most of the cost themselves.

　　When both vendors offered tickeks at the same price but only one required customers to enter their cell phone number, the more privacy-friendly yendor got 83% of sales. When participants were offered the santo choice, but with an additional charge of 50 euro cents from the privacy-friendly cinema, its market share fell to 31%.

　　"It turns out that when you are good on privacy you can charge more and make a greater profit," says Alessandro Acquisti of the University of Cambridge, one of the authors of the study, published by the European Network and Information Security Agency.

　　"What people say in surveys is that they care about privacy, but what they actually do is spend their time constantly updating their status on Facebo0k," says Acquisti. "This has led some to conclude that people no longer care about privacy. This new data, along with similar work we have done in the U. S, shows this is not the case, and that the desire for privacy is not dead after all. "

　　According to the passage, many people believe that A. we can benefit from selling our personal dataB. Internet giants should perfect their privacy policiesC. our privacy is the true currency of the InternetD. privacy campaigners should vote with their clicks
