Is the Internet Destroying Privacy?
As over-sharing becomes the norm, privacy becomes a relic of a bygone.
March 27, 2011— -- In an interview with TechCrunch last year, Facebook CEO Mark Zuckerberg said sharing private information online with the faceless masses had become a "social norm."
Interpretation: Privacy is a has-been luxury, a relic of a bygone, unwired era.
Today, oversharing has become typical of online social networking, with people publicizing real-time information of where they are (Foursquare, Gowalla) and what they're doing (Twitter, Facebook).
"It may be that social norms just haven't completely developed yet, but we end up revealing so much more than we likely would have without the Internet, and we reveal it to a much wider range of people," Lorrie Cranor, director of the CyLab Usable Privacy and Security Laboratory at Carnegie Mellon University.
Whether we're constantly updating our Facebooks and flickrs or not, we still leave behind a virtual breadcrumb trail anytime we hop online, thanks to data tracking software, cookies and web bugs that log what we search for, where we land and what we do once we get there.
"In a commercial setting, it used to be that if you go into a store, the store knows what you bought, and if you buy with credit cards they can tie it to your name, and if you pay cash they may not even know who you are," Cranor said. "But they didn't know all the things you took off the shelf, manipulated, put back on the shelf, thought about. On the Internet, they all have that."
Due to that online dossier about your habits, likes and dislikes, sites can serve up advertisements targeted directly to you.
Sure, plenty of websites offer privacy policies that explain what they will and won't do with any personal information they collect from visitors, but Cranor's studies show that people typically ignore them and don't understand the legalese, anyway.
And simply seeing a privacy policy without reviewing what it actually says often provides a false sense of security to consumers who might assume that "privacy" inherently implies protection from third-party intrusion.
"They are plenty of privacy policies that say 'we collect whatever we want from you and we do whatever want with it.' And that's a privacy policy," Cranor said. "It's not a very protective privacy policy, but it is a privacy policy."
