Pentagon LifeLog is ultimate diary

WASHINGTON — Coming to you soon from the Pentagon: the diary to end all diaries — a digital multimedia record of everywhere you go and everything you see, hear, read, say and touch.

Known as LifeLog, the project has been put out for contractor bids by the Defense Advanced Research Projects Agency, or DARPA, the agency that helped build the Internet and that is now developing the next generation of anti-terrorism tools.

The agency doesn't consider LifeLog an anti-terrorism system, but rather a tool to capture "one person's experience in and interactions with the world" through a camera, microphone and sensors worn by the user. Everything from heartbeats to travel to Internet chatting would be recorded.

The goal is to create breakthrough software that helps analyze behavior, habits and routines, according to Pentagon documents reviewed by the Associated Press. The products of the unclassified project would be available to both the private sector and other government agencies — a concern to privacy advocates.

DARPA's Jan Walker said LifeLog is intended for users who give their consent to be monitored. It could enhance the memory of military commanders and improve computerized military training by chronicling how users learn and then tailoring training accordingly, officials said.

But John Pike of Global Security.org, a defense analysis group, is dubious the project has military application.

"I have a much easier time understanding how Big Brother would want this than how (Defense Secretary Donald) Rumsfeld would use it," Pike said. "They have not identified a military application."

Steven Aftergood, a Federation of American Scientists defense analyst, said LifeLog would collect far more information than needed to improve a general's memory — enough "to measure human experience on an unprecedentedly specific level." And that, privacy experts say, raises powerful concerns.

DARPA rejects any notion LifeLog will be used for spying. "The allegation that this technology would create a machine to spy on others and invade people's privacy is way off the mark," Walker said.

She said LifeLog is not connected with DARPA's data-mining project, recently renamed Terrorism Information Awareness. Each LifeLog user could "decide when to turn the sensors on or off and who would share the data," she added. "The goal is to 'see what I see,' rather than to 'see me."'

One critic sees a silver lining in the government taking the lead.
