Researchers from Queen's University in Canada have proposed a way to protect important documents by generating so many believable fakes that attackers must either exfiltrate them all or attempt to find the real one, with either option increasing the risk of detection.

The team proved that creating and maintaining many fakes can be relatively inexpensive, and that the authentic document can be tracked using secret sharing.

To test the idea, the team built a system for creating and managing fake versions, as well as a secret sharing system to identify the real document. They also created a system to attempt to detect the real document among the fakes.

The researchers said, "There is conceptually an arms race between fake-building and fake-detecting algorithms, but our primary purpose is to show that it is possible to build fakes that are reasonably difficult to detect."
