The Policy Analysis Market, which provided a stock market of sorts for people to bet on terror strikes, was almost immediately withdrawn after its details came to light in July."Darpa's pretty gun-shy now," added Lee Tien, with the Electronic Frontier Foundation, which has been critical of many agency efforts. The Terrorism Information Awareness, or TIA, data-mining initiative was eliminated by Congress - although many analysts believe its research continues on the classified side of the Pentagon's ledger. "A change in priorities" is the only rationale agency spokeswoman Jan Walker provided.However, related Darpa efforts concerning software secretaries and mechanical brains are still moving ahead as planned.LifeLog is the latest in a series of controversial programs that have been canceled by Darpa in recent months. Darpa hasn't provided an explanation for LifeLog's quiet cancellation. But civil libertarians immediately pounced on the project when it debuted last spring, arguing that LifeLog could become the ultimate tool for profiling potential enemies of the state.Researchers close to the project say they're not sure why it was dropped late last month. Out of this seemingly endless ocean of information, computer scientists would plot distinctive routes in the data, mapping relationships, memories, events and experiences.LifeLog's backers said the all-encompassing diary could have turned into a near-perfect digital memory, giving its users computerized assistants with an almost flawless recall of what they had done in the past. What exactly was Operation Lifelog and what does it have to do with Facebook.The Pentagon has pulled the plug on LifeLog, its stunningly ambitious effort to build a database tracking a person's entire existence.Run by Darpa, the Defense Department's research arm, LifeLog aimed to gather in a single place just about everything an individual says, sees or does: the phone calls made, the TV shows watched, the magazines read, the plane tickets bought, the e-mail sent and received. DARPA's ambition Lifelog project was shut down the day Facebook was launched.
