GNSS Spoofing Suppression Based on Multi-Satellite and Multi-Channel Array Processing

Frontiers in Physics, 2022
The endless spoofing interference affects the credibility of the navigation system seriously. In order to suppress the forward spoofing which is more threatening to military signals in GNSS, this paper proposes a spoofing suppression algorithm based on ...

Speaker-Aware Anti-Spoofing [PDF]

, 2023
We address speaker-aware anti-spoofing, where prior knowledge of the target speaker is incorporated into a voice spoofing countermeasure (CM). In contrast to the frequently used speaker-independent solutions, we train the CM in a speaker-conditioned way.

Multimodal Anti-spoofing in Biometric Recognition Systems

, 2014
While multimodal biometric systems were commonly believed to be intrinsically more robust to spoof attacks than unimodal systems, recent results provided clear evidence that they can be evaded by spoofing a single biometric trait.
