A system and method for locating and accessing remote data over a computer network that provides data security and integrity. The system includes at least one data server located in a first region, at least one data server located in a second region, a first indexing and network management server providing authentication services for the at least one data server located in the first region, a second indexing and network management server providing authentication services for the at least one data server located in the second region, and a central registration server providing authentication services to the first and second indexing and network management servers, including maintaining valid public key certificates for each indexing and management server. A local server is authenticated by its regional indexing and management server, which provides an authentication passport to indexing servers, on behalf of the local server. Thus, a local server can be authenticated to remote data servers and can request information from the remote data servers. Methods of authentication and data integrity are also provided.
