Quantizer-Aware Hierarchical Neural Codec Modeling for Speech Deepfake Detection
Jinyang Wu, Zihan Pan, Qiquan Zhang +2
Neural audio codecs discretize speech via residual vector quantization (RVQ), forming a coarse-to-fine hierarchy across quantizers. While codec models have been explored for repres…
Exploiting the Final Component of Generator Architectures for AI-Generated Image Detection
Yanzhu Liu, Xiao Liu, Yuexuan Wang +1
With the rapid proliferation of powerful image generators, accurate detection of AI-generated images has become essential for maintaining a trustworthy online environment. However,…
Scores Know Bobs Voice: Speaker Impersonation Attack
Chanwoo Hwang, Sunpill Kim, Yong Kiam Tan +6
Advances in deep learning have enabled the widespread deployment of speaker recognition systems (SRSs), yet they remain vulnerable to score-based impersonation attacks. Existing at…
I Can Find You in Seconds! Leveraging Large Language Models for Code Authorship Attribution
Soohyeon Choi, Yong Kiam Tan, Mark Huasong Meng +4
Source code authorship attribution is important in software forensics, plagiarism detection, and protecting software patch integrity. Existing techniques often rely on supervised m…
