Time-Domain Voice Identity Morphing (TD-VIM): A Signal-Level Approach to Morphing Attacks on Speaker Verification Systems
Aravinda Reddy PN, Raghavendra Ramachandra, K. Sreenivasa Rao +2
In biometric systems, it is a common practice to associate each sample or template with a specific individual. Nevertheless, recent studies have demonstrated the feasibility of gen…
MorCode: Face Morphing Attack Generation using Generative Codebooks
Aravinda Reddy PN, Raghavendra Ramachandra, Sushma Venkatesh +3
Face recognition systems (FRS) can be compromised by face morphing attacks, which blend textural and geometric information from multiple facial images. The rapid evolution of gener…
Gumbel Rao Monte Carlo based Bi-Modal Neural Architecture Search for Audio-Visual Deepfake Detection
Aravinda Reddy PN, Raghavendra Ramachandra, Krothapalli Sreenivasa Rao +1
Deepfakes pose a critical threat to biometric authentication systems by generating highly realistic synthetic media. Existing multimodal deepfake detectors often struggle to adapt…
