Attack Potential Evaluation in Desktop and Smartphone Fingerprint Sensors: Can They Be Attacked by Anyone?

Table 9

Results on the vulnerabilities of each device to different artefact species. Not all materials were used in all sensors. A tick means that the device was successfully attacked with that species at least once. A cross indicates that the device could not be attacked with that material even once. An interrogation was used when the experiment was not tried.
