Search images on day

Assuming people set the clocks on their digital cameras (ha ha) correctly (ha ha), someone like Google could offer Image Search for photos taken on a certain day, by using EXIF information on jpegs. Or the camera can get the time from the cell network, or GPS, etc.

Someday, cameras will do GPS (some cell phones with cameras already have GPS, though I don't know if the encode the location information into the metadata) and we can search for all photos taken near a certain location at a certain time (and GPS can automatically get the correct time, too).

When Big Brother has us all get chips embedded in our skulls, and tracks our location via satellite, one could cross reference the people location data with the camera location (at a given point in time) to automatically identify people in a photograph. Or the camera could directly ping the Big Brother chips. These Big Brother chips could be the cell phones we already all carry around that record location at low resolution, or some Bluetooth variant.
