  • Patent number: 9886456
    Abstract: A storage unit of a time-series data accumulation device of an embodiment stores statistical value data. A determination unit determines an interval function on the basis of data capacity, and a total amount of time elapsed from the beginning of measurement of a time-series data. A first calculation unit calculates an interval indicating an amount of time required to measure all the time-series data items constituting desired statistical value data on the basis of the determined interval function. A second calculation unit acquires all the time-series data items on the basis of the calculated interval, and thereafter calculates the statistical value on the basis of all the acquired time-series data items.

  • Patent number: 8955041
    Abstract: A policy storage unit of an ID provider device according to an embodiment stores, for each service provider ID, policy information representing a user to which transmission of service data is permitted and policy information representing a user of a target in which transmission permission of service data is deleted. When a predetermined cycle comes or when a use status of the service provider device changes, the ID provider device acquires use status information of the service provider device transmitted from the service provider device, and updates a service use status storage unit based on the acquired use status information. When the service use status storage unit is updated, the ID provider device decides a deletion target account of each service provider ID.

  • Patent number: 8863305
    Abstract: In a file-access control system according to an embodiment of this invention, control data in accordance with actions made is imparted, as an obligation-type policy, to a document file. Next, a policy evaluation control unit evaluates and executes the obligation-type policy imparted to the document file in accordance with the action to the document file. The execution of the obligation-type policy includes the controlling of a document application on the basis of an obligation fulfillment action. Therefore, an active control can be performed in accordance with any manipulation made to the document, and the access to the document can be changed.
