Add-Ons to Online Social Profiles Expose Personal Data to Strangers
Facebook fanatics who have covered their profiles on the popular social networking site with silly games and quirky trivia quizzes may be unknowingly giving a host of strangers an intimate peek at their lives.
Those mini-programs, called widgets or applications, allow users to personalize their pages and connect with friends and acquaintances. But they could pose privacy risks. Some security researchers warn that developers of the software have assembled too much information — home town, schools attended, employment history — and can use the data in ways that could harm or annoy users.
“Everything requires you to give access to personal information or it forces you to ask your friends to do the same — it becomes a real nuisance,” said David Dixon, 40, an information technology consultant in Columbia who recently deleted most of the applications he had downloaded to his Facebook profile after reading on a blog that developers may have access to his information. “Why does a Sudoku puzzle have to know I have two kids? Why does a postcard need to know where I went to college?”
Even private profiles, in which personal details are available only to specific friends, reveal personal information, said Chris Soghoian, a cyber-security researcher at Indiana University. And they’re allowing access to their friends’ information — even if their friends are not using the application. That’s because MySpace and Facebook, the largest online social networks, let outside developers see a member’s information when they add a program.
“You want to be social with your friends, but now you’re giving 20 guys you’ve never met vast amounts of information from your profile,” he said. “That should be troubling to people.”
A year ago, Facebook started allowing outside developers to create small software programs for members to download. Since then, the company said, about 24,000 applications have been built by 400,000 developers. They’ve become enormously popular, with users playing poker, getting daily horoscopes and sending one another virtual cocktails, to name a few. More than 95 percent of Facebook users have installed at least one application, the company said.
Applications have grown so much that venture-capital firms have formed exclusively to fund their development, and there is a Stanford University course devoted to creating them.
