Two researchers from Michigan State University’s biometrics group have devised a method for hacking mobile phone’s fingerprint authentication by using just a color inkjet printer, a special type of paper and ink.
The first step is to scan the target’s fingerprint image at 300 dpi or higher resolution. Then, the image is mirrored and the original or binarized fingerprint image is printed on the glossy side of an AgIC special paper. The printer that does that is fed with AgIC silver conductive ink cartridges (along with normal black ink).
