Abstract:
Diffusion models have surpassed GANs in generating high-fidelity synthetic media, posing new challenges for deepfake detection. This paper presents a comprehensive comparative analysis of state-of-the-art detection techniques against both GAN-generated and diffusion-model-generated deepfakes. We introduce 'DiffDetectNet', a novel architecture optimized for identifying subtle artifacts unique to diffusion processes, demonstrating a 12% improvement in detecting diffusion-based fakes over models primarily trained on GAN data, while maintaining strong performance on GAN-generated content. Our findings highlight the need for evolving detection strategies in response to new generative model paradigms.
AI-Generated Insight:
This research addresses the challenge of detecting deepfakes created by advanced diffusion models. The proposed 'DiffDetectNet' architecture shows significant improvement in identifying diffusion-specific artifacts compared to older models trained mainly on GANs. This underscores the necessity for detection systems to adapt to the latest generative AI techniques.
Abstract:
The proliferation of deepfakes in live streaming scenarios demands efficient, low-latency detection methods. This paper investigates the challenges of real-time deepfake detection, including computational constraints and the need for rapid artifact analysis. We propose 'StreamGuard', a lightweight CNN-RNN hybrid model designed for on-the-fly processing of video streams. StreamGuard achieves a detection accuracy of 93.5% on benchmark live-stream deepfake datasets with an average processing latency of 35ms per frame on consumer-grade hardware, making it suitable for practical deployment.

This paper focuses on the critical need for fast deepfake detection in live video streams. 'StreamGuard', a hybrid CNN-RNN model, is presented as a lightweight solution that balances accuracy (93.5%) with low latency (35ms/frame), making it practical for real-world applications like video conferencing and live broadcasts.
Abstract:
Sophisticated deepfakes often exhibit subtle desynchronizations between audio and visual modalities, such as lip movements not perfectly matching speech, or unnatural emotional expressions incongruent with vocal tone. This work introduces 'AV-SyncNet', a novel multi-modal architecture that explicitly models and quantifies audio-visual synchronization. By learning fine-grained correlations between facial landmarks, lip motion, and speech prosody, AV-SyncNet significantly improves detection robustness, especially against fakes that are visually convincing but contain audio inconsistencies. We achieve state-of-the-art results on the FakeAVCeleb and KoDF datasets.
AI-Generated Insight:
This research tackles deepfake detection by focusing on inconsistencies between audio and visual information. 'AV-SyncNet' is a new multi-modal model designed to detect subtle mismatches in lip-sync, facial expressions, and voice tone. This approach proves effective against deepfakes that might appear visually flawless but have underlying audio-visual desynchronization, achieving top results on relevant datasets.
