      Engineers are working on software to load every photo you take, every letter
      you write -- in fact your every memory and experience -- into a surrogate
      brain that never forgets anything, New Scientist can reveal.

      It is part of a curious venture dubbed the MyLifeBits project, in which
      engineers at Microsoft's Media Presence lab in San Francisco are aiming to
      build multimedia databases that chronicle people's life events and make them
      searchable. "Imagine being able to run a Google-like search on your life,"
      says Gordon Bell, one of the developers.

      The motivation? Microsoft argues that our memories often deceive us:
      experiences get exaggerated, we muddle the timing of events and simply
      forget stuff. Much better, says the firm, to junk such unreliable
      interpretations and instead build a faithful memory on that most reliable of
      entities, the PC.

      Bell and his colleagues developed MyLifeBits as a surrogate brain to solve
      what they call the "giant shoebox problem". "In a giant shoebox full of
      photos, it's hard to find what you are looking for," says Microsoft's Jim
      Gemmell. Add to this the reels of home movies, videotapes, bundles of
      letters and documents we file away, and remembering what we have, let alone
      finding it, becomes a major headache.

      Logging life

      By the time he speaks at December's Association for Computing Machinery
      Multimedia conference in Juan Les Pins, France, Bell says he will have
      logged everything he possibly can onto his MyLifeBits database.

      Apart from official documents like his passport, he will post everything
      from letters and photos to home videos and work documents. All his email is
      automatically saved on the system, as is anything he reads or buys online.
      He has also started recording phone conversations and meetings to store as
      audio files. The privacy and corporate security risks are clear.

      Of course the system takes up a huge amount of memory. But Bell's group
      calculates that within five years, a 1000-gigabyte hard drive will cost less
      than $300 -- and that is enough to store four hours of video every day for a

      Each media file saved in MyLifeBits can be tagged with a written or spoken
      commentary and linked to other files. Spoken annotations are also converted
      into text, so the speech is searchable, too.

      To recall a period in his past, Bell just types in the dates he is
      interested in. MyLifeBits then calls up a timeline of phone and email
      conversations, things he has read and any images he recorded.

      The system can also be used to build narratives involving other people,
      events or places. Searching for the name of a friend would bring together a
      chronological set of files describing when you both did things together, for

      Meet the ancestors

      Although MyLifeBits is essentially a large database, it could gradually
      become a repository for many of our experiences. Now that many mobile
      devices contain photomessaging cameras, you could save everyday events onto
      the system.

      "Users will eventually be able to keep every document they read, every
      picture they view, all the audio they hear and a good portion of what they
      see," says Gemmell.

      Bell believes that for some people, especially those with memory problems,
      MyLifeBits will become a surrogate memory that is able to recall past
      experiences in a way not possible with the familiar but disparate records
      like photo albums and scrapbooks. "You'll begin to rely on it more and
      more," he believes.

      A really accurate, searchable store of events could also help us preserve
      our experiences more vividly for posterity. Doug de Groot, who works on
      computer-generated beings called avatars and other types of digital "life"
      at Leiden University in the Netherlands, says Bell's system could eventually
      form the basis for "meet the ancestor" style educational tools, where people
      will quiz their ancestors on what happened in their lifetimes.

      A system like MyLifeBits was first suggested in 1945, when presidential
      technology adviser Vannevar Bush hatched the then farsighted idea of an
      infinite personal archive based on the emerging digital computer. His ideas
      also inspired the internet archive website.
