According to one embodiment, an electronic device operable by a power supply voltage obtained from a commercial power supply, includes a capacitor charged with the power supply voltage, and a circuitry configured to write power failure occurrence time information to a nonvolatile memory using power of the capacitor after occurrence of power failure, read the power failure occurrence time information from the nonvolatile memory, and transmit the power failure occurrence time information to an external device.

Electronic device and method for managing power failure occurrence

According to one embodiment, a system program determines whether a boot mode of an information processing device is set to a first mode for booting an operating system from a storage device initialized by a master boot record (MBR) or a second mode for booting an operating system from a storage device initialized by a GUID partition table (GPT). The system program enables a first or second trusted platform module based on a result of determination of the boot mode.

Information processing device and version switching method of trusted platform module

According to one embodiment, an electronic apparatus includes a first detector, a second detector, a third detector and a security controller. The first detector detects a speed of movement of the electronic apparatus. The second detector detects a direction of the movement. The third detector detects whether the electronic device is located in a first area. The security controller updates position information wherein the position information is indicative of a first position in the first area, and executes a monitoring process based on the position information, detection information of the first detector and detection information of the second detector.

Electronic apparatus, security processing method and storage medium

According to one embodiment, an information processing apparatus includes a wireless communication module including an event notifier, an embedded controller and a setting module. The embedded controller registers event information configured to indicate that supply of electrical power to the wireless communication module was cut in a register and turns on the apparatus, when the embedded controller is started or reset. The setting module sets the wireless communication module to enable the event notifier, if the event information is registered in the register of the embedded controller when the apparatus is turned on.

Information processing apparatus and wireless communication module setting method

According to one embodiment, a storage stores secret data, first identification data, and a first random key. A generation module generates first authentication data from the secret data, first identification data, and second identification data of a removable medium. A first verification module determines whether the first authentication data and second authentication in the removable medium are identical. A second verification module determines whether the first random key and a second random key in the removable medium are identical, if the first and second authentication data are identical. An activation module activates the data processing apparatus if the first and second random keys are identical.
