Samsung looks into vein authentication

A patent filed by Samsung describes how a sensor on a smartwatch or other wearable device could authenticate identity by reading the user’s vein structure. “A wearable device may capture an image of a portion or all of the user’s body and may identify the user wearing the wearable device based on the captured image,” the patent says. “For example, a smartwatch may be worn on the user’s wrist to capture an image of the user’s veins in order to identify a user.”
