After the launch of the first generation Touch ID, a few smart bio hackers found a way to mimic the fingerprints of an individual to get a phone to unlock. However, it took major skills, equipment and knowledge to rightly do so. What if I told you can circumvent the new Galaxy S8 iris scanner using a black and white Samsung laser printer and a contact lens?

Well, that’s exactly what a group of researchers did. And it only took three simple steps. First, you take a photo using the night mode of the camera to gather the infrared information. Then, you print it on high resolution and real life dimensions on a laser printer. Finally, you place a contact lens on top of the eye to give it a rounder shape.


It’s pretty scary that this is all it took to make this work. Of course, you need some ingenuity but not a lot of skills or complicated devices to recreate a fake iris. Let’s hope a software update will make breaks this approach.
