Abstract: According to one embodiment, an electronic device includes a connector, a display module, and a receiver. The connector is configured to be connectable to a device comprising a keyboard. The display module is configured to display a software keyboard on which a key not comprised in the keyboard of the device is arranged when the device is connected to the connector. The receiver is configured to receive input from the key displayed as the software keyboard on the display module.

Abstract: According to one embodiment, a time-series information generating apparatus includes a dividing module, a determining module, a generating module, and a display module. The dividing module divides an electronic document to be displayed into one or more sets of sentences. The determining module determines a summary of each of the sets of sentences. The generating module generates time-series information that represents relative temporal information between anyone of the sets of sentences and another set of sentences. The display module collectively displays the summary of each of the sets of sentences according to the time-series information.

Abstract: According to one embodiment, an information processing apparatus includes a plurality of data encryption devices obtaining and encrypting contents data, a plurality of data decryption devices provided corresponding to the data encryption devices respectively, each of the data decryption devices obtaining the contents data via a user access bus from corresponding one of the data encryption devices and decrypting the contents data, and a data storage device storing the contents data encrypted by the data decryption devices, in which key data for decrypting the contents data stored in the data storage device is stored in one of the data encryption devices.

Abstract: According to one embodiment, an information processing apparatus comprising: a data acquisition unit that acquires contents data encrypted by a first encryption process; and a data processing unit that acquires and processes the contents data from the data acquisition unit; wherein the data acquisition unit is connectable to an IC card that includes decryption data for decrypting the contents data encrypted by the first encryption process; the data acquisition unit includes a plurality of data processor each decrypting the contents data encrypted by a first encryption process using the decryption data through a communication with the IC card; and an arbitration unit exclusively give one of the plurality of data processor a permission for establishment of the communication with the IC card.

Abstract: A ROM stores a device name table which holds a plurality of names each including an expression that allows to recognize the installation location of a device and a device unique ID that allows to identify the device. In response to a user request, a control device displays, as a list of choices on a display device, the plurality of names held by the device name table. When a name is selected, the control device makes the name correspond to the device unique ID and stores them in the name management table of a RAM and transmits the name management table to a server connected through a home network.
