Exploiting Neural Audio Codec Latents for Adversarial Audio Attacks
Sameek Bhattacharya, Bharath Krishnamurthy, Ajita Rattani
Deep learning-based audio classification systems, including automatic speaker verification, are vulnerable to adversarial attacks. Realistic real-time threat assessment remains dif…
MMFace-DiT: A Dual-Stream Diffusion Transformer for High-Fidelity Multimodal Face Generation
Bharath Krishnamurthy, Ajita Rattani
Recent multimodal face generation models address the spatial control limitations of text-to-image diffusion models by augmenting text-based conditioning with spatial priors such as…
VoxMorph: Scalable Zero-shot Voice Identity Morphing via Disentangled Embeddings
Bharath Krishnamurthy, Ajita Rattani
Morphing techniques generate artificial biometric samples that combine features from multiple individuals, allowing each contributor to be verified against a single enrolled templa…
DOOMGAN:High-Fidelity Dynamic Identity Obfuscation Ocular Generative Morphing
Bharath Krishnamurthy, Ajita Rattani
Ocular biometrics in the visible spectrum have emerged as a prominent modality due to their high accuracy, resistance to spoofing, and non-invasive nature. However, morphing attack…
