Abstract
A secure search mechanism (or search engine) for use with content based information security repositories. The present invention may be embodied in an information security system or method. In accordance with the present invention, a search occurs in a protected device that contains classified metadata and addresses of encrypted headers relating to classified data or information objects. A search request comes in from a user in a particular access level and the search engine returns a set of addresses that are at appropriate access levels and satisfy the search criteria. These addresses are passed or transferred to another device that stores the encrypted headers, and the encrypted headers are sent to the user.
