DARPA Shredder Challenge 2011 was a prize competition for exploring methods to reconstruct documents shredded by a variety of paper shredding techniques. The aim of the challenge was to "assess potential capabilities that could be used by the U.S. warfighters operating in war zones, but might also identify vulnerabilities to sensitive information that is protected by shredding practices throughout the U.S. national security community".[1] The competition was sponsored by the Defense Advanced Research Projects Agency (DARPA), a research organization of the United States Department of Defense.[2] Congress authorized DARPA to award cash prizes to further DARPA’s mission to sponsor revolutionary, high-payoff research that bridges the gap between fundamental discoveries and their use for national security.
As an example, solution of puzzle 2 from the DARPA Shredder Challenge.
Under the rules of the competition, the $50,000 challenge award would be granted to the first team to submit the answers to questions relating to a hidden mystery. The mystery verified that the team was able to extract meaningful intelligence from the page that was thought destroyed. The secret answers could be acquired by reconstructing five individual puzzles that were created by shredding one or more single-sided hand-written documents.[2]
In addition to the Shredder Challenge, DARPA has also conducted prize competitions in other areas of technology.
