摘要:
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 distribution system having plural elements including one or more computation devices holds distributed common data without distinction between master data and duplicate data upon entrance or withdrawal of the elements. Coincidence among the common data is obtained by majority rule. In the majority rule, a significance level is defined for each common data, and the significance level is utilized as a weight in majority rule for coincidence among the common data.

In a distributed system having a plurality of equipment that are interconnected over transmission medium and that include one or more arithmetic units, any of the plurality of equipment notifies a person to be notified about a function of the any of the equipment in accordance with an adaptive communication method in which the notification method is determined by the following steps. A first step that any of the plurality of equipment obtains environment information of that equipment and another equipment if necessary and a second step that any of the equipment determines the notification method depending on the environment information obtained by the first step and a contents of information concerning the function of any of the equipment.

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.

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.
摘要:
In distributed system for operating devices in association with one another, a device responsible for determining whether or not an access is permitted, and criteria for determination are hidden from accessing device or user, and flexible access control is provided among devices without need for previously defining accessible devices or user's identifiers. Communication process opens data communications which are interactions between devices to permit indefinite number of other devices to monitor data. A behavior monitoring process acquires interaction within particular device or between other devices in system for storage in behavior log table. Access control process matches the behavior log table with access control policy to determine whether or not device should be associated with target device from which process request is received, or with a target device to which a process program of the particular device attempts to access.

When conducting encryption key update, each of the network device successively causes transition among an initial state in which only data encrypted using an old encryption key used before the update can be transmitted and received, a state in which both data encrypted using the old encryption key and data encrypted using a new encryption key used after the update can be transmitted and received, but operation concerning transmission and reception of data encrypted using the new encryption key is not confirmed, a state in which both data encrypted using the old encryption key and data encrypted using the new encryption key can be transmitted and received, and operation concerning transmission and reception of data encrypted using the new encryption key is already also confirmed, and a final state in which only data encrypted using the new encryption key can be transmitted and received. The encryption key is thus updated.
摘要:
The present invention relates to a distributed system in which processors incorporated in machines and objects are mutually linked in operation, and an object of the present invention is to provide a distributed system in which each device can establish a link with a suitable device according to changes in the environment and conditions, independently from the system configuration controlled by a server.In order to achieve the above object, each device provided by the present invention obtains information on surrounding devices through a sensor 131 or communication processing 112, recognizes the environment around it through environment recognition processing 111, and stores the environmental information in an environment management table 123. By employing link control processing 113, each device shares conditional information stored in a profile 122 and a policy 124 of each device through the communication processing 112. Each device locally and continuously determines a device to be linked with it or whether to perform a link operation requested by another device, using the shared conditional information, information on the surrounding environment, and the policy 124. The results of a link operation are made public and shared by each device through the link control processing 113, and used for narrowing the range of link target devices.
摘要:
There is provided an evaluation object pattern determining apparatus capable of determining local patterns to be evaluated. The apparatus is for use in a pattern evaluating system storing patterns of a LSI chip as CAD data, picking out coordinates of local patterns whose process margin is small from the CAD data by way of simulation and assisting observation of the local patterns produced in a fabrication line. The apparatus includes a risk level map creating section for creating risk level maps in which risk areas are disposed. The risk area is assigned with a risk level obtained by digitizing that the risk area is an area whose process margin is smaller than other areas. The apparatus also includes a superimposition processing section for superimposing the coordinates of the local patterns with the risk level map to pick out the coordinates of the local patterns located within the risk area.
