Biometrics systems under spoofing attack: an evaluation methodology and lessons learned

The objective is to make the reader aware of the dangers associated with a blind trust in satellite positioning systems, especially for critical infrastructures : in such cases,

The work reported in this paper was designed to test these hypotheses, namely that: (i) an ensemble of relatively simple countermeasures, each tuned to the detection of artefacts
