The story of your life is being filmed and photographed each day, and soon will be searchable. Via PhysOrg:
A new surveillance camera by Hitachi Kokusai Electric can look at footage that contains an image of someone, either still or video, and then search other video or still images on file for other instances of that same face. It can search, process and display up to thirty six million faces in just one second. Each hit is displayed immediately, in thumbnail form, which its makers say, allows the camera to display the actions of a person prior to, or after, being seen by the surveillance camera.
