Samsung wants its smartwatches to identify you using your veins

Soon you won’t even need to do anything to have your smartwatch identify you if a recently published Samsung patent ever makes it into one of the company’s products. The patent is for a sensor on the bottom of a smartwatch that takes pictures of its user’s vein structure and unique characteristics, and then compares them to images that it’s taken before. Comparing the images allows the smartwatch to determine if the person wearing the smartwatch is its owner.
