PERSONAL AUTHENTICATION DEVICE AND PERSONAL AUTHENTICATION METHOD BY BIOLOGICAL INFORMATION

PROBLEM TO BE SOLVED: To easily perform biometric authentication, and easily perform personal authentication work by a portable terminal, etc. without having to carry a dedicated portable-type device.SOLUTION: A personal authentication device consisting of a device with an earphone which is capable of performing biometric authentication by electrocardiographic information includes an external ear electrode and an external electrode. The external ear electrode is provided on an earphone side, and is caused to come in contact with the external ear, and then the external electrode is touched with a hand so that electrocardiographic information is acquired. The acquired electrocardiographic information is stored, and the electrocardiographic information is transmitted to the portable terminal side as needed, thereby performing the biometric authentication.SELECTED DRAWING: Figure 1 【課題】本発明は、専用の可搬型機器を持ち歩かなくても、容易に生体認証が可能で、携帯端末等での個人認証作業を簡便に実施しようとするものである。【解決手段】イヤホンを有する装置からなり、心電情報による生体認証が実施できる個人認証装置であり、外耳電極と外部電極とを持っており、イヤホン側に外耳電極を設け、外耳に接触させ、外部電極に手を触れることで、心電情報を入手する。入手した心電情報を記憶し、必要に応じて携帯端末側に心電情報を送信し、生体認証を実施する。【選択図】図１
