We Broke into a Bunch of Android Phones with a 3D-Printed Head
- bsenftner 8y agoFR is one biometric. One biometric can be spoofed, as this article shows. For authentication of anything desiring security, such as financial transactions, it is recommended to have at minimum 3 biometrics. Considering a phone can perform financial transactions and is often a storage place for passwords, 3 biometrics should be required to unlock a phone. The iPhone's 3D FR is closer to 1.5 biometrics, and with added software analyzing successive video and 3D sensor "frames" it could become a full 2 biometrics - but one should still have a 3rd, such as fingerprint or passcode for financial authentications. But at that level, why have FR at all? In time, within a year, publicly available FR systems will have "spoof detection" suites. The FR software I work on does, but this is just the beginning. Non-living 3D objects, such as that 3D printed head, fail under motion analysis because it lacks the momentary flush of a human pulse, and likewise that can be used to detect prosthetics on a face. Additionally, it is too rigid, faces undergo constant subtle deformation - the lack of that is also a spoof detection method.
