Yomiuri Shimbun: シュレッダー文書、紙片1万個の復元に成功
Tetsurō Yamada reporting from Washington December 3, 2011

A team from California successfully deciphered an entire set of 10,000 shredded pages, winning a contest hosted by DARPA, the US Defense Department’s Defense Advanced Research Projects Agency, and a $50,000 prize, DARPA announced on the 2nd.

About 9000 teams participated in the competition. The winner was a small group of computer programmers from San Francisco who invented a program which finds a way to reassemble the strips of paper, then presents its model to human users for confirmation. It successfully recovered 5 types of documents and 10,000 pages in all.

Some experts had previously thought completing such a task in a short amount of time would be impossible. The department said the winning team’s solution was the most effective because it employed not only computing but also human ability.
