U.S. spies are developing technology that would allow computers to pinpoint where in the world a picture was taken. The system would be used by the military to track down terrorists who are in hiding in remote regions, experts said.
Pictures of the targets would be simply scanned into a computer that would within seconds return an exact match for the terrorist hideout. Troops would then be deployed to the area to capture the target. The futuristic technology could revolutionise the way that terrorists are targeted by the CIA and other intelligence agencies.
It is now known exactly how the new technology is hoped to work. However, the computer may cross-reference clues in the picture with a vast database of images until a match is found.
A more advanced method would be to deduce the air pressure from the photograph and link it to a region with similar conditions at the time the photograph was taken. IARPA admitted that such advanced technology might not be available until 2016.
'The Finder Program aims to develop technology that, with the aid of an analyst, geolocates an outdoor image or video taken from anywhere on the land surface of the world, via the use of publicly available information,' IARPA said.
The agency said that the technology would have to be capable of pinpointing the location of pictures or videos within one minute, without the use of metadata or tags.
Google has recently introduced a 'reverse search' feature to its image facility which allows users to scour the web to similar pictures to one that they already have.
