摘要:
In providing services in an environment in which apparatuses constituting a system change dynamically, flexible control of access control is performed for the apparatuses whose access rights and service providing policies are different or have not been set beforehand. In a distributed system where computers each having a function of storing data and processing a program and a communication facility perform data exchange through a communication medium, and thereby perform processing, control of limiting an access to the system etc. is performed as a shared session that is established by synthesizing access rights and service providing policies owned by the apparatuses, and accesses to the apparatuses and provision of services are performed through the shared session, whereby the access rights and the services to be provided are controlled according to a configuration of apparatuses constituting the system.

A system allows a user to select a service on a device and request a service executing function of a server to carry out the service. An authentication function authenticates the user and searches the functions of devices required in the requested service within the authority given to the user. The function acquires and registers the right to use in a device-configuration managing function through a right-to-use managing function. An adaptor delivering function delivers specifications for setting connections between functions required for execution of the service and a group encryption key generated by a key-generating function to devices. Device coordinating functions set device-embedded functions based on the received specifications. The functions conduct cipher communication with other devices using the key and carry out the service.

For a group consisting of a plurality of users, data of users who constitute the group is acquired. Thereafter, the users are made to stay in a certain area by determining a user having high importance in the group based on the user data acquired and by providing adequate data to a user having high importance, and then data related to the group is provided. With the arrangement, for a case where a plurality of intended persons are to simultaneously receive data such as advertising and such intended persons form a group, it is possible to effectively notify data in an adequate method.

A guidance system which may include: a position direction obtaining unit which obtains a current position and moving direction of an operation device; a destination information obtaining unit which obtains destination information; a route information generating unit which generates route information to the destination from the current position by use of map information; an output device management unit which manages an installation position of the output device; an output device selecting unit which selects one output device from the plurality of output devices, on the basis of information of the current position, moving direction and installation position of the output device; a selected output device presenting unit which presents an information that specifies the selected output device to the operation device; and an information display instructing unit which displays the generated route information displayed on the selected output device in accordance with the information to be specified.
摘要:
An object of the invention is to save the trouble of mapping sensor chips on a map information system. A map information management unit 124 is accessed via a network 122. Neighborhood information based on a present position measured by an own position measuring unit 102 is obtained by searching a map DB 127. A sensor information setting unit 106 displays the neighborhood information in a display unit 108. An ID reading unit 104 reads an ID 111 of a sensor chip 110, and registers the ID 111 in the map DB 127 after associating it with equipment information displayed in the display unit 108. The measurement values measured by a sensor 112 are transmitted from an antenna 114 and received by a sensor information receiving unit 119 of the receiver 118. A sensor information communication unit 120 accesses the network 122 and the measurements are transmitted to a sensor information management unit 123. The measurement values are accumulated in a sensor DB 126. The sensor DB 126 is searched using a sensor ID associated in the map DB 127 and the measurements are viewed as map information associated with equipment.

摘要:
A processing device has a personal authentication information receiving unit for receiving personal authentication information, a security information DB, and a processing information managing unit. The processing information managing unit converts the personal authentication information received by the personal authentication receiving unit to a user ID, detects an event concerning a processing operation, and associates the event with the user ID, thereby creating or updating an access management table for processing performance information, for storage in the security information DB. The processing information management unit then controls access to the processing performance information based on the access management table and the user ID obtained by conversion of the personal authentication information received by the personal authentication information receiving unit.
