Face ID can be tricked by twins, masks

Apple's new Face ID technology suffers from some security vulnerabilities.

Since the launch of the iPhone X, many were wondering if Apple's new Face ID technology will be accurate and secure enough to replace Touch ID.

Some online reviewers went as far as to making masks of their own faces to see if they can trick Face ID, but failed in the process. More recently, however, a security research firm by the name of Bkav has claimed that they have managed to fool the system using a 3D-printed face mask, combined with makeup. Since the iPhone is set up to recognise faces even when they are partially obstructed by an accessory, such as glasses or a hat, researchers found that they could fool the device into unlocking with as little as half a face printed in 3D. The company has also mentioned that with devices like the Xperia XZ1, creating full-face 3D scans no longer require full rig setups.

More interestingly, some reviewers have tried fooling the Face ID scanner with identical twins, achieving mixed results. Younger twins were easily able to trick the device, as well as the majority of more mature twins, provided their facial features passed a certain threshold of similarity.

Apple's comment on this has been that in the case of twins, the likelihood of the system not working as intended increases the younger the twins, claiming that individual facial details are not yet fully developed. The company has yet to issue a statement on researchers claiming to circumvent the security via masks.

QTF Recommends: If you use an iPhone X as a personal or work smartphone, make sure to update its software frequently to benefit from any upcoming enhancements to Face ID. Additionally, if any of the aforementioned security vulnerabilities may pose a threat to you, we recommend considering alternative options to secure your device, such as per-app security options and folder passwords.
