Ten years before the recent global panic over the U.S. government’s domestic spying program, the Pentagon solicited contractors for a searchable database of people’s lives.
In 2003, the Department of Defense’s Defense Advanced Research Projects Agency (DARPA) hoped to create a database that would amass everything about the life of a person participating in the project, ranging from GPS coordinates to every email and phone call sent and received.
The participant would wear a camera, microphone and sensors to record the minutia of everyday life. The program, called Lifelog, would act as a person’s digital diary.
Lifelog was a feature  of DARPA’s Perceptive Assistant that Learns (PAL) program, which was meant to create intelligent digital personal assistants.
