You Are What You Share

The old maxim used to go something like, “you are what you eat”. Well, in the early 21st century it has been usurped by, “you are what you share online (knowingly or not)”.

Not so long ago, there was a familiar product called software. It was sold in stores, in shrink-wrapped boxes. When you bought it, all that you gave away was your credit card number or a stack of bills.

Now there are “apps”—stylish, discrete chunks of software that live online or in your smartphone. To “buy” an app, all you have to do is click a button. Sometimes they cost a few dollars, but many apps are free, at least in monetary terms. You often pay in another way. Apps are gateways, and when you buy an app, there is a strong chance that you are supplying its developers with one of the most coveted commodities in today’s economy: personal data.

Some of the most widely used apps on Facebook—the games, quizzes and sharing services that define the social-networking site and give it such appeal—are gathering volumes of personal information.

A Wall Street Journal examination of 100 of the most popular Facebook apps found that some seek the email addresses, current location and sexual preference, among other details, not only of app users but also of their Facebook friends. One Yahoo service powered by Facebook requests access to a person’s religious and political leanings as a condition for using it. The popular Skype service for making online phone calls seeks the Facebook photos and birthdays of its users and their friends.

Yahoo and Skype say that they seek the information to customize their services for users and that they are committed to protecting privacy. “Data that is shared with Yahoo is managed carefully,” a Yahoo spokeswoman said.

The Journal also tested its own app, “WSJ Social,” which seeks data about users’ basic profile information and email and requests the ability to post an update when a user reads an article. A Journal spokeswoman says that the company asks only for information required to make the app work.

This appetite for personal data reflects a fundamental truth about Facebook and, by extension, the Internet economy as a whole: Facebook provides a free service that users pay for, in effect, by providing details about their lives, friendships, interests and activities. Facebook, in turn, uses that trove of information to attract advertisers, app makers and other business opportunities.

Up until a few years ago, such vast and easily accessible repositories of personal information were all but nonexistent. Their advent is driving a profound debate over the definition of privacy in an era when most people now carry information-transmitting devices with them all the time.

Capitalizing on personal data is a lucrative enterprise. Facebook is in the midst of planning for an initial public offering of its stock in May that could value the young company at more than $100 billion on the Nasdaq Stock Market.

Facebook requires apps to ask permission before accessing a user’s personal details. However, a user’s friends aren’t notified if information about them is used by a friend’s app. An examination of the apps’ activities also suggests that Facebook occasionally isn’t enforcing its own rules on data privacy.
