Hackers foil Samsung S8's iris recognition technology using only a photo of an eye

Launched as the technology giant's comeback phone after the disastrous roll-out of the fire-prone Note 7 handset, the phone allows users to unlock the device merely by pointing the camera at their unique iris patterns.

Tricking the S8's iris recognition system by utilizing 'night mode,' Europe's largest association of German hackers, the collective Chaos Computer Club (CCC), fooled the phone's sensor with infrared light.

The infrared image was then printed using a laser printer and a contact lens placed on the printed photograph of the infrared image.

When held up to the phone, it was recognised as the eye of the person for whom the handset was registered to and unlocked itself. sky.com
