Electronic device for measuring biometric information and method for operating the same

A method for operating an electronic device, the method comprising:

• receiving first data from a photoplethysmogram (PPG) sensor of the electronic device;
• generating second data by band-pass filtering the first data;
• generating oxygen saturation data based on at least some of the second data;
• selecting a first portion related to a first period of time from the second data;
• and
• displaying, on a touchscreen display, a graphical user interface comprising information related to the oxygen saturation data except for data corresponding to the first portion from the graphical user interface.

An electronic device, comprising:

• a photoplethysmogram (PPG) sensor;
• a processor operatively connected to the PPG sensor;
• and
• a memory operatively connected to the processor,
• wherein the memory is configured to store instructions that, when executed, are configured to cause the processor to:
• acquire a PPG signal for a user from the PPG sensor;
• identify signal distortion of first data due to pressure applied to a body of a user by the PPG sensor, based on at least a portion of second data generated by band-pass filtering the first data corresponding to the PPG signal;
• and
• in response to identifying that there is no signal distortion of the first data, identify biometric information using the PPG signal.
