Abstract: In processing of initializing a setting of a communication parent device, whether a communication child device has been registered is determined. In a case where the communication child device has been registered, a user is notified that the communication child device has been registered, and the user is guided to registration removal processing for the communication child device. In a case where removal of registration of the communication child device is instructed by the user's operation, registration information of the communication child device in the communication parent device is deleted.

Abstract: An information processing apparatus includes a storage unit, an encryption processing unit that encrypts data to be stored in the storage unit, and a control unit that stores a first key in a unit different from the encryption processing unit, wherein the first key, which is used to decrypt data encrypted by the encryption processing unit and stored in the storage unit, is encrypted using a second key set in the encryption processing unit.

Abstract: An information processing apparatus is connected to a plurality of storage devices and performs mirroring between the plurality of storage devices. In accordance with a data writing command, a writing command is issued to each of the plurality of storage devices, and, in a case that a response indicating writing completion for the writing command is received from a first storage device out of the plurality of storage devices, a predetermined amount of time is waited for the response from the other storage device. When the response is not received from the other storage device within the predetermined amount of time, a response indicating writing completion is notified to an issuing source of the data writing command, and after the notification, data stored in the first storage device is mirrored by copying it to the other storage device.

Abstract: An information processing apparatus operable in a first power state and a second power state includes a noncontact communication unit configured to be driven by power of a radio wave from a mobile terminal and to communicate with the terminal, a storage unit configured to store data necessary for authentication, which the noncontact communication unit has received from the terminal in the second power state, a control unit configured to recover, when the noncontact communication unit receives data from the terminal in the second power state, the information processing apparatus from the second power state to the first power state, and a transmission unit configured to transmit, after the information processing apparatus has been recovered to the first power state by the control of the control unit, the data necessary for authentication stored in the storage unit to an authentication unit.

Abstract: A mirroring device that can improve, even when two storage devices to which an upper limit is set for the number of rewrites of data are used, the fault tolerance of the mirroring device while preventing one of the storage devices from reaching the lifetime thereof early. A mirroring device comprises two storage devices to which an upper limit is set for the number of rewrites of data. Remaining writable amounts of the data in the storage devices are acquired respectively from total amounts of the data written in the respective storage devices. When it is determined that a difference between the respective acquired remaining writable amounts is less than a predetermined value, the respective storage devices are controlled such that the difference becomes equal to or more than the predetermined value.

Abstract: According to one embodiment, in a case where a test on an encryption device indicates an error in an encryption process of the encryption device, a data processing device holds a result of the test on the encryption device in a holding unit, and notifies that the encryption device has an error on the basis of the result of the test on the encryption device.

Abstract: An image processing apparatus that is capable of being instructed to power off, by a power switch or a command from an external apparatus, and is capable of executing the restart thereof under appropriate conditions. When power-off is instructed, shutdown is started. Upon completion of the shutdown, if the power switch is on, and at the same time the power-off has been instructed by the power switch of the apparatus, the restart of the apparatus is executed, whereas upon completion of the shutdown, if the power-off has been instructed by a command from the external apparatus, the restart of the apparatus is not executed.
