is a strategy to identify the source of an information leak that involves distributing different versions of the same story to different entities. If one of the stories leaks, the entity responsible can potentially be identified.

Example

A firm has experienced its product plans being leaked to the media. The CEO believes that it is a top level executive who is the source of the leaks. The firm communicates different fictitious products to the head of marketing, sales and operations with instructions that the information is strictly confidential. If one of the stories leaks, the source may be identified.

Risks

People typically find out that you have given them incorrect information and may deduce that you don't trust them. This can backfire.
