BiometricJammer: Use of Pseudo Fingerprint to Prevent Fingerprint Extraction from Camera Images without Inconveniencing Users
Isao Echizen, Tateo Ogane · 2018
As fingerprint authentication technology becomes more advanced, it is being used in a growing range of personal devices such as PCs and smartphones. However, fingerprints can also be captured remotely by using a digital camera, leading to possible illegal logins or identity theft. We have improved our previously proposed method preventing fingerprint acquisition from photographs while still enabling contact-based fingerprint sensors to respond normally. Evaluation of its jamming effect on photographed fingerprints and on fingerprint sensors showed that the improved method can be implemented with a less distracting appearance and that it works as well as the conventional method.
