1. A human recognition apparatus, comprising: a detecting unit, located at a distance from a user, detecting a ground vibration according to a user's walking, and outputting an electric signal; a pattern calculating unit acquiring a walker's walking pattern from the electric signal; and a user determining unit comparing the walking pattern with a previously measured reference data by user and identifying the user based on the comparison result, wherein the detecting unit comprises: a vibration sensor outputting an electric signal corresponding to peripheral vibration; and a high pass filter eliminating a low frequency noise from the electric signal.
