LifeLog was a project of the Information Processing Techniques Office of the Defense Advanced Research Projects Agency (DARPA) of the U.S. Department of Defense (DOD). According to its bid solicitation pamphlet, it was to be "an ontology-based (sub)system that captures, stores, and makes accessible the flow of one person's experience in and interactions with the world in order to support a broad spectrum of associates/assistants and other system capabilities." The objective of the LifeLog concept was "to be able to trace the 'threads' of an individual's life in terms of events, states, and relationships", and it has the ability to "take in all of a subject's experience, from phone numbers dialed and e-mail messages viewed to every breath taken, step made and place gone." == Goals and capabilities == "LifeLog aims to compile a massive electronic database of every activity and relationship a person engages in. This is to include credit card purchases, web sites visited, the content of telephone calls and e-mails sent and received, scans of faxes and postal mail sent and received, instant messages sent and received, books and magazines read, television and radio selections, physical location recorded via wearable GPS sensors, biomedical data captured through wearable sensors, The high level goal of this data logging is to identify "preferences, plans, goals, and other markers of intentionality."〔(PIP 03-30 ), DARPA's bid solicitation for LifeLog (now offline) * (Archived copy of PIP 03-30 ) at the Internet Archive 〕 The DARPA program was canceled in 2004 after criticism from civil libertarians concerning the privacy implications of the system. Generically, the term ''lifelog'' or ''flog'' is used to describe a storage system that can automatically and persistently record and archive some informational dimension of an object's (object lifelog) or user's (user lifelog) life experience in a particular data category. News reports in the media described LifeLog as the "diary to end all diaries — a multimedia, digital record of everywhere you go and everything you see, hear, read, say and touch." According to U.S. government officials, LifeLog is not connected with Total Information Awareness.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「DARPA LifeLog」の詳細全文を読む スポンサード リンク
