Electronic device

An electronic device comprising:

• an impedance measuring unit including electrodes, which generates a first measurement signal of a first frequency and a second measurement signal of a second frequency, applies the first measurement signal and the second measurement signal to a user, and obtains each of first biometric impedance data to fourth biometric impedance data, based on one of first electrodes and second electrodes of the electrodes;
• and
• a signal processor which extracts first feature data of the user, based on the first biometric impedance data to the fourth biometric impedance data, and
• wherein the first feature data are based on a ratio between values of any two data among the first biometric impedance data to the fourth biometric impedance data.
