Abstract: 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.

Abstract: An architecture to deliver web applications to users that is comprised of links to virtual applications that are composed of physical applications (e.g., a software component with special rules). The web applications can be created, combined into larger applications and installed without the typical effort of writing and debugging software code. Building blocks are derived from a standard interface and rules including that none of the components call methods from any other component. The interfaces pass knowledge, and an agent basket holds properties of a job. Data needed to carry out tasks is found from resources other than the interface (e.g., database). Agencies actively monitor job postings (bulletin board posts) and call agents having a highest score for performing the job. Only active agents and components are maintained in computer memory and are killed when finished, minimizing system footprint and reducing hardware costs.
