Speech frame selection for spoofing detection with an application to partially spoofed audio-data [PDF]
International Journal of Speech Technology, 2021 In this paper, we introduce a frame selection strategy for improved detection of spoofed speech. A countermeasure (CM) system typically uses a Gaussian mixture model (GMM) based classifier for computing the log-likelihood scores. The average log-likelihood ratio for all speech frames of a test utterance is calculated as the score for the decision ...

Satellite Navigation Spoofing Interference Detection and Direction Finding Based on Array Antenna
Sensors, 2023 Satellite navigation signals are feeble when they reach the ground, so they are vulnerable to attacks from outside interference signals. By emitting spoofing interference signals similar to real satellite signals, spoofing interference can make receivers

Synthetic spoofing speech detection method based on center-symmetric local binary pattern
Dianxin kexue, 2023 In view of the fact that the local binary pattern (LBP) based speech spoofing detection method has low detection accuracy when detecting synthetic speech, a spoofing speech detection method based on center-symmetric local binary pattern (CSLBP) was ...

Visual spoofing in content-based spam detection [PDF]
13th International Conference on Security of Information and Networks, 2020 Although the problem of spam classification seems to be solved, there are still vulnerabilities in the current spam filters that could be easily exploited. We present one such vulnerability, in which one could replace some characters with corresponding characters from a different alphabet.
