Provided is an individual identification device capable of further improving individual identification accuracy in an individual identification device using a high frequency electrocardiogram. The personal identification device (1) has an electrocardiogram / high frequency electrocardiogram acquisition unit (10) having a pair of electrocardiographic electrodes (11, 12) and acquiring an electrocardiogram and a high frequency electrocardiogram from which low frequency components are removed from an electrocardiogram, an electrocardiogram / A peak extracting section (21) for differentiating the peak of the R wave and extracting a zero crossing point corresponding to the peak of the R wave, an HFECG cutting out section (22) for cutting out a high frequency electrocardiogram for a predetermined range including the extracted zero cross point, A high frequency electrocardiogram of the plurality of registrants as a registered high frequency electrocardiogram, a high frequency electrocardiogram of the subject to be identified which is cut out and a registered high frequency electrocardiogram stored in advance are compared with each other , And an individual identification unit (26) for identifying the identification target person based on the similarities between the two.高周波心電図を用いた個人識別装置において、個人の識別精度をより向上させることが可能な個人識別装置を提供する。 個人識別装置(1)は、一対の心電電極(11,12)を有し、心電図、及び心電図から低周波成分を除去した高周波心電図を取得する心電図/高周波心電図取得部(10)と、心電図を微分して、R波のピークに対応するゼロクロス点を抽出するピーク抽出部(21)と、抽出されたゼロクロス点を含む所定範囲について、高周波心電図を切り出すHFECG切出部(22)と、切り出された、複数の登録者の高周波心電図を、予め登録高周波心電図として記憶するHFECG記憶部(25)と、切り出された識別対象者の高周波心電図と、予め記憶されている登録高周波心電図とを比較し、双方の類似度に基づいて、識別対象者を識別する個人識別部(26)とを備える。
