PSST! Amazon.com does not want you to know what it knows about you. It not only tracks the books you purchase, but also keeps a record of the ones you browse but do not buy to help it recommend other books to you. Information from its e-book, the Kindle, is probably even richer: how long a user spends reading each page,whether he takes notes and so on, But Amazon refuses to disclose what data it collects or how it uses them.
It is not alone,Across the internet economy, comparues are compiling masses of data on people, their activities, their likes and dislikes, their relationships with others and even where they are at any particular moment-and keeping mum. For example, Facebook, a social-networking site, tracks the activities of its 400m users, half of whom spend an average of almost an hour on the site every day, but does not talk about what it finds. Google reveals a little but holds back a lot. Even eBay, the online auctioneer, keeps quiet.
"They are uncomfortable bringing so much attention to this because it is at the heart of their competitive advantage," says Tim O'Reilly, a technology insider and publisher. "Data are the coin of the realm. They have a big lead over other companies that do not 'get' this." As the communications director of one of the web's biggest sites admits, "we're not in a position to have an in-depth conversation. It has less to do with sensitive considerations like privacy. Instead, we're just not ready to tip our hand. " In other words, the firm does not want to reveal valuable trade secrets.
The reticence partly reflects fears about consumer unease and unwelcome attention from regulators. But this is short-sighted, for two reasons. First, politicians and the public are already anxious. The chairman of America's Federal Trade Commission, Jon Leibowitz, has publicly grumbled that the industry has not been sufficiently forthcoming. Second, if users knew how the data were used, they would probably be more impressed than alarmed.
Where traditional businesses generally collect information about customers from their purchases or from surveys, internet companies have the luxury of being able to gather data from everything that happens on their sites. The biggest websites have long recognized that information itself is their biggest treasure. And it can immediately be put to use in a way that tradit/onal firms cannot match.
Some of the techniques have become widespread. Before deploying a new feature, big sites run controlled experiments to see what works best. Amazon and Netflix, a site that offers films for ture, use a statistical technique called collaborative filtering to make recommendations to users based on what other users like. The technique they came up with has produced millions of dollars of additional sales. Nearly two-thirds of the film selections by Netflix's customers come from the referrals made by computer.
