Why Reality Mining Is Dangerous
Reality Mining is a process which mines various machine-sensed data which could be used predict human behavior. In case of cell phones, it has been used to provide a uniquely rich record of people’s locations, actions, social behavior, and even social roles. The research at MIT is sponsored by Nokia.
This is one of those stories which may seem to be ’so far out there’ but it has caused many to raise concerns. See the views from Nicholas Carr’s RoughType blog on reality mining. Do you know for sure that your call data is secure? My concern is that for a variety of reasons, data from emerging telecom markets is susceptible to abuse and reality mining presents one of ways to make use of this data. The privacy laws in Pakistan and other developing countries are so weak (if there are any) that its only a matter of time before a problem is reported.
Here’s more via Business Week:
Nathan Eagle, a research scientist at the MIT Design Laboratory, is currently working with a database that holds an entire month’s worth calling data for a whole European country, though he won’t say which one. Scrubbed of all information that might be used to identify people, the data set contains information on 250 million phones and some 12 billion phone calls.
Wireless companies could use the information to help keep customers from switching to a rival—a strategic must in a region where most of the population already has a cell phone and “new” customers are scarce. Eagle mines the data for a range of information, such as identifying so-called influencers, who use their phone the most. Not only are these subscribers valuable because they use their phone a lot, but they’re also more likely to influence other people’s service and product purchases—and to take customers with them when they switch. “If someone who makes a lot of calls walks away, there’s a higher potential that they’ll take more people along with them,” Eagle says.
