A memory stores common identification information that is shared between a plurality of information provision institutions for identifying a person. A processor assigns the common identification information to personal information transferred to a storage device from a plurality of operation databases respectively of the plurality of information provision institutions. Then, the processor generates confidentialized personal information by confidentializing the personal information to which the common identification information has been assigned.

Information processing apparatus, information processing system and information processing method

A metadata processing unit acquires the first metadata from a first data storing unit at a first frequency and makes a second data storing unit store the first metadata. A file data processing unit specifies, based on the update history of the first metadata, second metadata that is updated on and after the last acquisition date and time of second file data stored in the second data storing unit, acquires the first file data associated with the specified management data at a second frequency that is lower than the first frequency, and makes the second data storing unit store the first file data. A switching unit switches a read/write process that is performed by using the operation data stored in the first data storing unit such that the read/write process is performed by using the second metadata and the second file data in the second data storing unit.

Information processing system, information processing apparatus, and information processing apparatus control method

A control device, which controls access to the data stored in a memory device, includes a selector, a changing unit, a notification unit, and a power supply controller. When the number of accesses to a memory device is out of a range of a predetermined threshold, the selector selects a piece of data from pieces of data controlled by the control device itself or another control device. The changing unit changes a control device for controlling access to the selected a piece of data. The notification unit notifies an information processing device of a control device after changed and the selected a piece of data to be controlled by the control device after changed. The power supply controller controls a power supply of the control device after changed or a power supply of a control device that has controlled access to the selected a piece of data.

Apparatus and method for controlling power supply of control device that controls access to data

A storage controller selecting system includes a time information storage unit, a receiver, and a processor. The time information storage unit is configured to store internal processing time information for each of a plurality of storage controllers. The internal processing time information for each individual storage controller relates to an internal processing time taken for processing performed within the individual storage controller in response to an access request to a logical volume. The receiver is configured to receive a creation request for requesting creation of a new logical volume. The processor is configured to select a certain storage controller from among the plurality of storage controllers according to the internal processing time information, and to cause the certain storage controller to create the new logical volume.
