Abstract
A method and computer program product for managing restricted content, such as confidential or classified content, using content signatures are provided. A registry is established within an indexed archive system for content signatures of restricted files. Participants enroll in the registry and submit content signatures of all their files to the registry. The registry compares the submitted content signatures to those stored previously in the registry. The registry initiates a control action whenever there is a match between a participant's content signature and a previously stored content signature of a file to which the participant does not have access rights. When there is no match, the participant retains access to the restricted file.
