Abstract: Provided is an information processing apparatus including a structure analysis unit that analyses display control data including multiple structural units, in each of which information relating to display control is written, and extracts the structural units included in the display control data, a first structuring unit that generates first structured data for display control by linking, except for a structural unit in which information involving script processing is written, the structural units including at least a structural unit in which information relating to a layout of a display screen is written, among the extracted structural units, a second structuring unit that generates second structured data for display control by linking all of the extracted structural units, and a display control unit that displays a display screen using the first structured data, and, at a stage the second structured data is generated, redisplays the display screen using the second structured data.

Abstract: Provided is a data acquisition method including the steps of selecting a link destination whose display is at least partially located in a region of a display screen corresponding to an operating tool, acquiring, before the link destination is selected, information relating to a layout of a display screen and display control data including at least a structural unit in which the information is written, the display control data and the information existing at the link destination, extracting structural units included in the display control data, in a case the prefetched link destination is selected, generating first structured data by linking the extracted structural units in which information involving script-process isn't written, generating second structured data by linking the extracted structural units, displaying a display screen using the first structured data, and redisplaying, at a stage the second structured data is generated, the display screen using the second structured data.

Abstract: Provided is a data acquisition method including the steps of selecting one or more of at least one link destination, acquiring, before the link destination is selected, display control data including at least a structural unit in which information relating to a layout of a display screen is written, the display control data existing at the link destination selected in the previous step, extracting structural units included in the display control data before the prefetched link destination is selected, generating, before the prefetched link destination is selected, first structured data for display control by linking the extracted structural units in which information involving script processing is not written, generating, in a case the prefetched link destination is selected, second structured data for display control by linking the structural units, displaying a display screen using the first structured data, and redisplaying the display screen using the second structured data.

Abstract: This invention relates to a service providing system and a service providing method for allowing users to receive a service from a service server without having to submit their security-critical information to that server. A CE device 1 requests provision of the service by transmitting authentication information such as a device ID to a surrogate authentication server 2. The surrogate authentication server 2 authenticates the CE device 1 based on the authentication information and transmits a result of the authentication to the service server 3. In turn, the service server 3 provides the CE device 1 with the requested service based on the result of the authentication received from the surrogate authentication server 2. The CE device 1 then uses the service provided by the service server 3. This system can be applied advantageously to network-based marketing systems.

Abstract: This invention is intended to build a system with service cores integrated. A user terminal sends authentication information and area information to an image service providing server via a network. The image service providing server receives the authentication information and the area information from the user terminal, selects an authentication server of an area corresponding to the area information from among authentication servers of all areas, and sends the authentication information received from the user terminal to the selected authentication server via the network. The authentication server receives the authentication information of the user terminal from the image service providing server and executes the authentication of the user terminal on the basis of the received authentication information. The present invention is applicable to image service providing systems which provide image-based services.
