Hello, the face scanning security feature in 10, has been defeated with the use of a printed out picture. From a report: In a report published yesterday, German pen-testing company SySS GmbH says it discovered that Hello is vulnerable to the simplest and most common attack against facial recognition biometrics software — the doomsday scenario of using a printed photo of the device’s owner. Researchers say that using a laser color printout of a low-resolution (340×340 pixels) photo of the device owner’s face, modified to the near IR spectrum, they were able to unlock several devices where Hello had been previously activated. The attack worked even if the “enhanced anti-spoofing” feature had been enabled in the Hello settings panel, albeit for these attacks SySS researchers said they needed a photo of a higher resolution of 480×480 pixels (which in reality is still a low-resolution photo). […] Microsoft released updates earlier this month to patch the vulnerability.
