According to one embodiment, an electronic apparatus includes a biological sensor, an extraction module, a state detector, and a transmission controller. The biological sensor generates first biological data. The extraction module extracts one or more first features from the first biological data. The state detector detects a communication state between a communication module and a server. The transmission controller transmits at least one of the first biological data and the one or more first features to the server, based on the detected communication state.
