In a distribution system including a plurality of physical machines, when an output file output by first processing performs multistage processing input to second processing, a physical machine which is a deployment destination of a first virtual machine for performing the first processing, a physical machine which is a storage destination of each data block included in the output file, and a physical machine which is a deployment destination of a second virtual machine for performing the second processing are determined based on relationship between the first and second processing.

Distribution system, computer, and arrangement method for virtual machine

Provided is a technology for improving the efficiency and the accuracy of data security. To this end, protection information provided to data is maintained correct even when it becomes necessary to change the necessity/non-necessity to protect the data depending on the content of a process performed on the data. More specifically, primitive data with protection attributes set thereon is read as the original data, and an operation is performed on the original data to generate derived data. Then, whether to make the derived data inherit the protection attributes of the original data is determined on the basis of a content of the operation performed on the original data.

Data management method

Since a nonvolatile RAM allows random reading and writing operations, an erasing mode is unnecessary. From the system side, however, it is desirable to have the erasing mode because of its nonvolatile characteristic. Moreover, the erasing operation is desirably carried out at high speed with low power consumption. Therefore, memory cell arrays COA and DTA containing a plurality of memory cells MC each having a magnetoresistive element are provided, a series of data is written to the memory cell arrays COA and DTA, and at the time of erasing, an erasing operation is carried out by writing predetermined data only to the memory cell array COA.

Semiconductor storage device and data processing method

In an apparatus of reproducing contents in which an encryption key is to be changed at predetermined intervals for copyright protection purpose, the contents can be reproduced or specially reproduced with no problem such as fast forward, and fast rewind. For special reproduction, data and key information needed therefor are made ready in advance, and using the data and the key information, the contents are specially reproduced. Alternatively, an encryption key generation rule is defined in advance for use in generation of an encryption key. By making any needed key information ready in advance from this rule, the contents can be reproduced and specially reproduced with no problem.

Content reproduction apparatus, recording apparatus, recording and reproduction apparatus, and reproduction method

The present invention improves user-friendliness and protect content with increased reliability when judging whether network devices belong to the same home network. While the connection to a network is established, each network device uses a peripheral device information collection unit to collect peripheral device information indicating which ones of devices are connected to the network, and store the collected information in a peripheral device information storage unit as home network information. When the belonging of a remote device is to be judged, the home network information stored in the remote device is received. A peripheral device information collation unit collates the received home network information with the home network information stored in the peripheral device information storage unit to judge whether the remote device belongs to the same network as the local device.

Network system, network device, and network belonging judgment method

There are provided a cellular telephone device and transmitter for setting a cellular telephone to answering mode and a telephone section to sleep status when communication forbidding information is received, and restoring telephone section operation when there is no communication forbidding information and canceling silent mode and answering mode; and automatically setting silent mode and answering mode when a communication forbidding signal is received, and maintaining the telephone section operation status when there is no communication forbidding information, and canceling silent mode and answering mode.

Cellular telephone device and transmitter to cellular telephone

A cellular phone which is easy to use featuring a sufficient degree of safety preventing unauthorized use by conducting a minimum degree of required authentication operation which is not perceived by the user. As the user holds the cellular phone by hand, the control unit issues an instruction to temperature obtaining units to start detecting the temperature. The temperature obtaining units measure the temperature at regular intervals, and successively transfer the obtained temperature data to a temperature comparator unit The temperature comparator unit judges whether the temperature data obtained by the temperature obtaining units are lying within a predetermined condition, and issues an instruction to biodata obtaining units to obtain fingerprint data of the user depending upon the result of judgement. The biodata obtaining units obtain the fingerprint data of the user and transfer the obtained fingerprint data to a biodata authentication unit The biodata authentication unit compares the obtained fingerprint data with the fingerprint data of the owner stored in a biodata storage unit and judges whether the user is the proper user.
