Analysis of spoof surface plasmons in spoof-insulator-spoof waveguides

Journal of Electromagnetic Waves and Applications, 2016
AbstractHerein, we present a detailed analysis of the propagation of surface waves along spoof-insulator-spoof (SIS) waveguides. Analytical dispersion equations are derived for the geometry under investigation, in view of the presence of the semiconductor and transparent conducting oxide (TCO) corrugations.

Discriminative Frequency Information Learning for End-to-End Speech Anti-Spoofing

IEEE Signal Processing Letters, 2023
End-to-end technology is an active research topic in speech anti-spoofing. Although end-to-end methods have achieved remarkable success in the speech anti-spoofing, channel effects brought by telephony transmission and certain challenging forms of ...

Spoof Trace Disentanglement for Generic Face Anti-Spoofing

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2022
Prior studies show that the key to face anti-spoofing lies in the subtle image patterns, termed "spoof trace," e.g., color distortion, 3D mask edge, and Moiré pattern. Spoof detection rooted on those spoof traces can improve not only the model's generalization but also the interpretability.

Detection of Spoofing Medium Contours for Face Anti-Spoofing

IEEE Transactions on Circuits and Systems for Video Technology, 2021
Face anti-spoofing is an important step for secure face recognition. In this paper, we target on building a general classifier to detect the face images with spoofing medium contours (termed as SMCs for simplicity). To this end, we consider the task of face anti-spoofing as the detection of SMCs from the image.

A GNSS Instrumentation Covert Directional Spoofing Algorithm for UAV Equipped With Tightly-Coupled GNSS/IMU

IEEE Transactions on Instrumentation and Measurement, 2023
Measurement and navigation users cannot operate without the positioning, navigation, and timing (PNT) service provided by the global navigation satellite system (GNSS) instrumentation, but users are also faced with unpredictable and complex interference ...

CodecFake: Enhancing Anti-Spoofing Models Against Deepfake Audios from Codec-Based Speech Synthesis Systems

Interspeech
Current state-of-the-art (SOTA) codec-based audio synthesis systems can mimic anyone's voice with just a 3-second sample from that specific unseen speaker.
