PROBLEM TO BE SOLVED: To provide a biological information measurement device capable of more effectively preventing unauthorized measurement in which another person is substituted for a subject to be measured by acquiring a biological impedance as identification information for executing identification for authenticating personal identification during the execution of measurement of biological information with respect to the subject to be measured.SOLUTION: A biological information measurement system has: registering means capable of registering a subject to be measured by using a previously measured biological impedance of the subject to be measured as the identification information of the subject and a measuring means capable of acquiring the biological impedance of the subject to be measured while executing measurement of the biological information of the subject to be measured. The system also has an identification means for comparing the biological impedance acquired during execution of the measurement by the measurement means to the registered biological impedance as identification information to execute determination as to whether or not the measured subject for which the measurement is executed is the same as the subject to be measured registered by the registering means.COPYRIGHT: (C)2013,JPO&INPIT【課題】被測定者に対する生体情報の測定が実行されている間に、本人であることの判別を実行するための識別情報である生体インピーダンスを取得することにより、被測定者以外の人物が摩り替わる不正な測定をより効果的に防止する。【解決手段】予め測定された被測定者の生体インピーダンスを被測定者の識別情報として、被測定者を登録可能な登録手段と、被測定者の生体情報の測定を実行しながら、被測定者の生体インピーダンスを取得可能な測定手段と、を有する。また、測定手段が測定の実行中に取得した生体インピーダンスを、識別情報である登録済み生体インピーダンスと比較して、測定が実行された被測定者と、登録手段により登録された被測定者とが同一人物であるか否かの判別を実行する判別手段を有する。【選択図】図1
