Abstract: Disclosed is a system for detecting falsification, the system having: a confirmation information preparing unit preparing confirmation information of source data of published content published on the Internet; a confirmation information holding unit holding the confirmation information of the source data at a predetermined point in time; a source data alteration detecting unit detecting an alteration in the source data; a reflecting unit reflecting the altered source data in the confirmation information of the confirmation information holding unit and in the published content; a published content alteration detecting unit performing alteration detection on the published content; a published content alteration notifying unit notifying a predetermined terminal of information relating to altered published content; and a controlling unit controlling detection of inappropriately altered published content, based on the confirmation information of the source data and on the confirmation information of the published

Abstract: The simulator is provided with a control section that gathers the parameters of a plurality of parts in a computer network and that thereby predicts a future state of the computer network over a prescribed period of time. Further, a scenario creation/management creates a model corresponding to the computer network. Finally, simulation engine executes the simulation on the basis of the created model.

Abstract: A simulator includes a model generation/management section that generates and manages a model corresponding to a system to be simulated; a scenario generation/management section that prepares a future-forecasting scenario for verifying a state that the system does not satisfy a predetermined performance standard in future, and at the same time, prepares a design-supporting scenario for verifying a state that the system satisfies the predetermined performance standard; a simulation engine that executes a simulation corresponding to the future-forecasting scenario or the design-supporting scenario; and a simulation control section that controls a simulation corresponding to the design-supporting scenario or the future-forecasting scenario based on a result of a simulation of the future-forecasting scenario or the design-supporting scenario.
