  • Patent number: 7715326
    Abstract: A system and method for preventing unauthorized access to a website's sensitive information in which a website web server is located on a public network with a public IP address and known port number, but only performs a listening function. The responding function is located on a separate device on a private network with a private and dynamic IP address and having a randomly assigned port number. The responder has no listening sockets (open ports expecting to receive from client application) and therefore does not listen to the public network, and therefore is not accessible to unauthorized access, much in the way that a private user's PC is not accessible to unauthorized access. The web server having the listening function does not initiate connection with the device having the responding function because its private IP address is unreachable from the public network and unknown, even to the web server, and by virtue of the fact that there are no listening sockets to accept any requests.

  • Patent number: 6571140
    Abstract: A system and method provide the creation and operation of remote real-time data monitoring and control systems. Such applications include a communications gateway coupled to real-time devices. The communications gateway transforms the real time data collected from disparate and non-interoperable systems in a single common data format. The communications gateway provides an object server with a list of the real-time devices to which the communications gateway is connected, and their attributes. The object server publishes this list. Subscribers can access this list, and request subscriptions to specific attributes of certain devices. The object server creates a data object corresponding to the requested information. A subscriber includes a service agent which accesses the object server. In addition, a subscriber may also comprise presentation cells, which provide a representation and mapping of data objects and hence underlying devices and systems, to allow a user to manage and control such systems.

  • Patent number: 6067477
    Abstract: A system and method provide for the creation and operation of real-time enterprise-wide, personalize supervisory and control data acquisition systems. Personalized SCADA applications are constructed from a virtual application service and a personal agent framework using simple drag and drop operations or other high level action. The virtual application service includes a communications gateway that communicates with disparate and non-interoperable systems and external field devices to communicate low level time data collected from such systems into the application environment transforming the collected data in a single common data format. The virtual application service includes application cells that receive the reformatted data and process it to provide high level analysis and context, storing the processed data in an object server. The object server provides a unified, hierarchical object model for all of the data received from the underlying devices and systems.
