  • Publication number: 20030005287
    Abstract: A system and method that provides electronic security over a network through an extensible positive client identifier (EPCI), working with a positive information profiling system (PIPS), pseudo uniform resource locators (PURLs) to assist in providing data integrity, a virtual page publication system (VPPS), and an active security responder, (ASR). The extensible positive client identifier (EPCI) creates a unique client identification key and continually self-evaluates the key based on unique system signature data. The positive information profiling system implements account profiles for all content and clients so that pages of information can be generated and matched to the data requested as well as the requester. The virtual page publication system VPPS of the invention does not store pages permanently in the root directory of the site but instead creates temporary web pages dynamically containing the level of information resulting from the client identification, PIPS, and PURL evaluations.
