Lifeblog is an application developed at Nokia will help the user to take track of his/her life recording some glimpse of the day in the form of sounds, pictures, or texts. This system is based on the idea that every person wants to author this content and eventually publish it on the web to create a sort of bibliographical information. This bites, once collected can be organised/aggregate into a sort of portal where they can be retrieved with different criteria.
