Samsung patent details biometric authentication method based on blood flow

Categories Biometric R&D  |  Biometrics News

A Samsung patent for an continuous authentication method via blood flow was published last week by the World Intellectual Property Organization (WIPO).

According to a LetsGoDigital report, international patent number PCT/KR2017/007827 describes a method to measure and analyze the blood flow of a user using special sensors, including, but not limited to, heart rate, PPG, ECG and GSR sensors. Blood flow is unique for each person and can be measured using a finger, wrist, arm, leg, ankle, chest and or a forehead.

According to the accompanying patent images, this appears to be a secondary way to authenticate identity on everything from laptops to wearables.

Earlier this month, Samsung patented a tablet-like rollable display device with an integrated fingerprint sensor. The OLED display can be rolled up into a small tube, which houses the fingerprint sensor.
