  • Patent number: 7349959
    Abstract: The present invention creates a SOAP message without using DOM by generating a body part by sequentially performing such a process of a message as encryption or signing for each piece of the message, generating a header part by using information acquired during the process, and by combining the body part and the header part. The present invention also breaks a SOAP message without using DOM by acquiring header information with parsing a received SOAP message and sequentially performing decode or verification of a signature of a body part according to the header information.

  • Publication number: 20070185904
    Abstract: Provides graphics display apparatus, systems and methods for effectively presenting information obtained by data mining, and to improve the visibility of the display of individual data elements and attributes of data included in a particular category while allowing an overview of whole large-scale hierarchical data to be provided. An example embodiment includes an aggregation unit for performing aggregation of attributes of nodes in the hierarchical data according to given aggregation criteria; a filtering unit for filtering the result of aggregation performed by the aggregation unit according to given filtering criteria to select nodes to be displayed from the hierarchical data; and a visualization unit for generating a graphics image that includes the nodes to be displayed selected by the filtering unit and reflects the hierarchical structure of the hierarchical data.

  • Publication number: 20060036754
    Abstract: Reduces time for processing a request Simple Object Access Protocol, SOAP, message in a request means such as mobile equipment or the like. Sequence definition means divides one parent SOAP message as one request concerning a Web Service into segments of a Simple Object Access Protocol header and a SOAP body. Segment creation means creates the segment of the Simple Object Access Protocol body of the parent SOAP message and the segment of the SOAP header of the parent Simple Object Access Protocol message in this order. Sending means executes sending processing in parallel with creation processing by the segment creation means. Specifically, the sending means assigns one child Simple Object Access Protocol message enveloping the content of a segment to each of the segments, and sends each of the child Simple Object Access Protocol messages to the provider in accordance with a creation sequence of the segments.

  • Publication number: 20050237320
    Abstract: A graphic area is provided in which graphics represent constitutional elements of a predetermined layer. A graphics image generation apparatus includes an element arrangement unit (22) for arranging graphics representing constitutional elements in a layer lower than the predetermined layer according to the layered data and an arrangement control unit (23) for executing arrangement of graphics for each of the layers reflexively from the lower to the upper layer of the layered data, thereby generating graphics image of the layered data.

  • Publication number: 20050039054
    Abstract: An authentication system with a single sign on having less influence on the service performance to provide a service via a network. The authentication system comprises a provider 20 for providing a service, a security token service 40, and a proxy service 30 interposed between the security token service 40 and the provider 20. The proxy service 30 preserves an authentication result of the security token service 40, and vicariously executes the authentication for a client based on the authentication result preserved by itself without transferring an authentication request received from the provider 20 to the security token service 40 under certain conditions. Moreover, when it is clear that a service can be provided to the client based on the service use history of the client 10 preserved by itself, the provider 20 provides the service to the client 10 without making the authentication request.
