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…
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…
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,…
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…
Unsupervised Fingerphoto Presentation Attack Detection With Diffusion Models
Hailin Li, Raghavendra Ramachandra, Mohamed Ragab +3
Smartphone-based contactless fingerphoto authentication has become a reliable alternative to traditional contact-based fingerprint biometric systems owing to rapid advances in smar…
