You’re Leaving a Digital Trail. What About Privacy?

By John Markoff of the New York Times, November 29, 2008

For the last 50 years, Americans have worried about the privacy of the individual in the computer age. But new technologies have become so powerful that protecting individual privacy may no longer be the only issue. Now, with the Internet, wireless sensors, and the capability to analyze an avalanche of data, a person’s profile can be drawn without monitoring him or her directly.

“Some have argued that with new technology there is a diminished expectation of privacy,” said Marc Rotenberg, executive director of the Electronic Privacy Information Center, a privacy rights group in Washington. “But the opposite may also be true. New techniques may require us to expand our understanding of privacy and to address the impact that data collection has on groups of individuals and not simply a single person.”

Dr. Sandy Pentland of the MIT Media Lab says there are ways to avoid surveillance — society pitfalls that lurk in the technology. For the commercial use of such information, he has proposed a set of principles derived from English common law to guarantee that people have ownership rights to data about their behavior. The idea revolves around three principles: that you have a right to possess your own data, that you control the data that is collected about you, and that you can destroy, remove or redeploy your data as you wish.

At the same time, he argued that individual privacy rights must also be weighed against the public good.

Citing the epidemic involving severe acute respiratory syndrome, or SARS, in recent years, he said technology would have helped health officials watch the movement of infected people as it happened, providing an opportunity to limit the spread of the disease.

“If I could have looked at the cellphone records, it could have been stopped that morning rather than a couple of weeks later,” he said. “I’m sorry, that trumps minute concerns about privacy.”

Indeed, some collective-intelligence researchers argue that strong concerns about privacy rights are a relatively recent phenomenon in human history.

“The new information tools symbolized by the Internet are radically changing the possibility of how we can organize large-scale human efforts,” said Thomas W. Malone, director of the M.I.T. Center for Collective Intelligence.

“For most of human history, people have lived in small tribes where everything they did was known by everyone they knew,” Dr. Malone said. “In some sense we’re becoming a global village. Privacy may turn out to have become an anomaly.”
