The invention provides security policy generation methods and devices for generating a security policy that is set up for an information processing apparatus comprises a step of generating an application model having a transmitter and a receiver of a message decided, for each of a plurality of messages that are communicated, a step of storing in advance a plurality of security patterns with a signer of electronic signature appended to the message as an undecided parameter, a step of selecting a security pattern that is a model of security policy to be setup for the transmitter or receiver of the message, corresponding to each of the plurality of messages included in the application model, and a step of substituting the identification information of the transmitter or receiver of each message included in the application model for the undecided parameter of the security pattern selected corresponding to the message.

Security policy generation

The invention provides security policy generation methods and devices for generating a security policy that is set up for an information processing apparatus comprises a step of generating an application model having a transmitter and a receiver of a message decided, for each of a plurality of messages that are communicated, a step of storing in advance a plurality of security patterns with a signer of electronic signature appended to the message as an undecided parameter, a step of selecting a security pattern that is a model of security policy to be set up for the transmitter or receiver of the message, corresponding to each of the plurality of messages included in the application model, and a step of substituting the identification information of the transmitter or receiver of each message included in the application model for the undecided parameter of the security pattern selected corresponding to the message.

Provided are a method, system, and program for processing call requests with respect to objects. A call request is received with respect to an object. Access authority for the object is require. An access authority set is read for execution of the call request with respect to the object. A determination is made as to whether the access authority is contained in the access authority set. A storage section storing execution results for a previous execution of the object is searched prior to executing the call request and in response to determining that the access authority is contained in the access authority set.

Processing call requests with respect to objects

A web page acquisition system, provider, method, computer readable memory and program of instructions for web page acquisition that reduces the waiting time that is experienced by a user who accesses a network site when the network is busy and also reduces the load that is imposed on the server of a provider.

System and method for web page acquisition

Provides methods, apparatus and systems for message request response server and processor. A server apparatus including: a request processing unit for performing processing for a first processing request message received, and creating a first processing response message; a cache unit for caching the first processing response message in association with a first key created based on the first processing request message; a message analysis unit for analyzing the second processing request message received; a key creation unit for creating a second key based on the analysis result; and a cache management unit for returning the cached first processing response message when the second key coincides with the first key, and when the second key does not coincide with the first key, notifying the result of the analysis, allowing the request processing unit to perform processing based on the analysis result, and returning the second processing response message created.

Message request response server and processor

A system and method thereby each of a plurality of agent servers keeps and manages history of movement. Each of the agent servers temporarily stores requests for updates of location information of a mobile agent associated to accumulated number of movement of the mobile agent and periodically sends it to a registration server so that no congestion will occur in accessing the registration server. The registration server renews location information of a mobile server only with the request for update of a higher accumulated number of movements so as not to overwrite newer information with older information.

Apparatus and method for managing mobile agents

To provide a message sending function which reflects 'taste' in a destination agent designated by a user and a policy of the market in which agents operate. When multicasting a message to agents, a message monitor executes the steps of: receiving preferential destination information designated by a user along with the message; determining to which agents the message is to be sent, by referring to the preferential destination information; and sending the message to the agents determined as destinations. This preferential destination information designated by a user is the information representing a user's 'taste' which is represented, for instance, by an agent name and a priority (or weight). It is also possible that the destination determining step comprises a step of referring to a messaging policy data defining priorities of agents to which the message can be sent. By doing so, it becomes possible to reflect a policy of a market's sponsor on message sending. Moreover, it is also possible to transform it so that a message destination is determined by referring only to a messaging policy data rather than preferential destination information designated by a user.

Message multicast method and computer

Flow control for a workflow controlling system is achieved wherein a business document flows among a plurality of participants by, at a system which includes a server apparatus including a storage device and terminal apparatus connecting to the server apparatus via a network, generating a document which includes data and rules responding to a request from one of the terminal apparatus and storing it in the storage device, receiving an update request on the document from the first terminal apparatus, determining whether the update request is appropriate or not, and if the update request is appropriate then executing the update on the document, and determining whether the workflow/process was completed or not, and if not completed then identifying the second terminal apparatus which can update next and notifying it.

Method, system, storage medium and server apparatus for controlling workflow

To control the load on an agent server, it is necessary to store any inactive agent in a secondary storage device, release a memory and a thread occupied by the agent, and control the number of simultaneously active agents. The agent server reads out an agent from the secondary storage device when a processing of the agent starts, and writes the agent into the secondary storage device when the processing of the agent is terminated. By doing so, the memory and the thread occupied by the agents which are not processing are released. It also limits the number of simultaneously active agents by starting a processing of another agent upon termination of the processing of one agent. In the present invention, the start and the termination of the processing are determined by the start and the termination of a conversation between the agents. Messages are in compliance with a predetermined rule. Accordingly, if this conversation rule includes definition of types of messages to the flow of messages exchanged in a series of processes, the start and the termination of a conversation can be detected by referring to the message and the conversation rule.
