New York Times: You’re Leaving a Digital Trail. What About Privacy?
The New York Times has an interesting story about students allowing researchers to track every call made, e-mail or text sent, or song played on their smartphones, in exchange for free use of the phones.
The students’ data is but a bubble in a vast sea of digital information being recorded by an ever thicker web of sensors, from phones to GPS units to the tags in office ID badges, that capture our movements and interactions. Coupled with information already gathered from sources like Web surfing and credit cards, the data is the basis for an emerging field called collective intelligence.
Propelled by new technologies and the Internet’s steady incursion into every nook and cranny of life, collective intelligence offers powerful capabilities, from improving the efficiency of advertising to giving community groups new ways to organize.
But even its practitioners acknowledge that, if misused, collective intelligence tools could create an Orwellian future on a level Big Brother could only dream of.
Collective intelligence could make it possible for insurance companies, for example, to use behavioral data to covertly identify people suffering from a particular disease and deny them insurance coverage. Similarly, the government or law enforcement agencies could identify members of a protest group by tracking social networks revealed by the new technology.
One researcher highlights the significant privacy and security problems:
But Dr. Estrin said the project still faced a host of challenges, both with the accuracy of tiny sensors and with the researchers’ ability to be certain that personal information remains private. She is skeptical about technical efforts to obscure the identity of individual contributors to databases of information collected by network sensors.
Attempts to blur the identity of individuals have only a limited capability, she said. The researchers encrypt the data to protect against identifying particular people, but that has limits.
“Even though we are protecting the information, it is still subject to subpoena and subject to bullying bosses or spouses,” she said.
