The iris scan, which identifies people from the pattern of blood vessels in the eye, has long been considered to be among the most secure of biometrics. But new research suggests that the iris scan
may not be as secure as people think. As with computers, cell phones, portable electronics charging stations, and aerial drones, iris scans can be vulnerable to hackers.
