According to one embodiment, a server device includes a memory and a processor. The memory stores verification information. The processor accepts a request to transmit a certificate number, generates information in which identification information of one of storage devices from which data is to be erased, a public key, a secret key, and the certificate number are associated with one another, transmits the certificate number, performs verification using an authenticator transmitted by the one storage device and verification information, generates, based on a result of the verification, an erasure certificate that includes the identification information and the certificate number and is signed using the secret key, and transmits the erasure certificate.

System, server device, and storage device

According to an embodiment, an activity meter includes an acceleration sensor configured to detect acceleration in at least one axis direction, an acceleration energy detection section configured to detect acceleration energy based on an acceleration signal of the acceleration sensor and a control section. The control section determines removal of the activity meter from a target person based on acceleration energy detected by the acceleration energy detection section and an acceleration component in a direction of gravity in the acceleration signal of the acceleration sensor.

Activity meter and sleep/awake state recording system

According to one embodiment, an electronic thermometer includes a temperature sensing unit, a conversion unit, an FSK modulation unit, and a transmission unit. The temperature sensing unit detects the temperature of a subject. The conversion unit converts a result detected by the temperature sensing unit to a digital signal. The FSK modulation unit converts the digital signal from the conversion unit to an FSK modulation signal. The transmission unit outputs a transmission signal including a pilot signal having a frequency assigned to the FSK (frequency shift keying) modulation signal and the FSK modulation signal subsequent to the pilot signal.
