To provide a blood treatment filter device capable of efficiently utilizing a blood treatment filter.A blood treatment filter device 20 has a filter sheet 26 through which a specific component among components forming blood is harder to pass than other components and a spacer sheet 27 through which the specific component is easier to pass than through the filter sheet 26. The filter sheet 26 has filter through-holes 39 disposed at intervals. The filter sheet 26 and the spacer sheet 27 are spirally wound in an overlapped state. The filter device 20 has seals 31 sealing both end portions in the longitudinal direction of a wound body 25 formed by the filter sheet 26 and the spacer sheet 27 which are spirally wound in a fluid-tight manner. The outer peripheral surface of the wound body 25 is formed by the filter sheet 26.

According to an aspect of the present invention, there is provided a data transmitting apparatus including an authenticator generating unit and a communicating unit. The authenticator generating unit generates a first authenticator by using a first encryption key and generates a second authenticator including a first to an n-th fragment information items by using a second encryption key. The communicating unit transmits a first packet including the first authenticator and the first fragment information item to a destination device and, after the first packet is transmitted, if a response indicating successful authentication is not received from the destination device within a certain period, sequentially transmits an i-th packet (i is an integer being 2 or more and n or less) including the i-th fragment information item to the destination device.

According to an embodiment, in a power usage calculation system, a data management system connected to electric power meters adding up power usage of electric apparatuses and an energy management system are interconnected through a network. Plural pieces of the first partial information are calculated by using the power usage added up by the electric power meters. The plural pieces of the first partial information are stored in storage servers. Each storage server calculates second partial information by using a plurality of pieces of the first partial information of the power usage added up by the electric power meters and transmits the calculated second partial information to the energy management system. The energy management system receives the second partial information respectively transmitted from the storage servers and calculates a total amount of the power usage added up by the electric power meters by using the received second partial information.

An apparatus includes a server connected between a first computer network in which a computer virus may generate and a second computer network or a computer system as an object of security protection. In the apparatus, a collection unit collects irregular data representing a possibility of generation of the computer virus that may attack the server. A decision unit decides whether the computer virus is being generated on the computer network in accordance with the irregular data. A notification unit notifies the second computer network or the computer system of generation of the computer virus when the decision unit decides that the computer virus is being generated.

A software distribution system and a software utilization scheme for effectively preventing an illegal copy of a software is difficult while improving a convenience of a user. At a user side, a shared key to be shared between a software provider and a user is stored, where the shared key has a guaranteed correspondence with an ID information regarding a payment of a software fee by the user. Then, a desired software is requested to the software provider, and the desired software is received in an encrypted form from the software provider. The desired software received from the software provider is then decrypted by using the shared key stored at the user side, and the desired software in a decrypted form is utilized at the user side.

According to an embodiment, a data converting device is connected to a power meter configured to add up power consumptions of electrical equipment. The device includes a receiving unit configured to receive power consumptions per predetermined unit time added up by the power meter; and a calculating unit configured to calculate a second sequence to be stored as added up power consumptions in a storage unit from a first sequence containing the power consumptions per unit time received by the receiving unit in time series by using a conversion rule for converting a value of a second element in the second sequence based on a value of a first element in the first sequence. The second sequence has no privacy information and, the second sequence can be used for calculating a total value of the first sequence.
