A quantum resilient deepfake detection framework using enhanced resnext and post quantum cryptography defence
Quantum-Resilient Deepfake Detection for the Enterprise
This research introduces 'DeepQShield', a novel quantum-resilient deepfake detection framework leveraging an enhanced ResNeXt convolutional neural network. It integrates lattice-based adversarial training (Learning with Errors - LWE) for superior robustness against traditional and quantum adversarial attacks. Further secured with post-quantum cryptography (Kyber for key exchange, Dilithium for digital signatures), DeepQShield ensures authenticity and encryption of detection results. Achieving an impressive 99.28% accuracy and 0.9997 AUC on the DFDC dataset, it significantly outperforms existing models and is designed for secure, scalable real-world applications like face forensics and social media data authentication.

Deepfakes, generated by AI and GANs, pose significant threats across politics, social media, and law by mimicking real individuals and creating false evidence. Existing detection methods are vulnerable to quantum adversaries and advanced adversarial attacks. Our 'DeepQShield' framework addresses this by combining a robust ResNeXt CNN with lattice-based adversarial training (LWE) and post-quantum cryptography (Kyber, Dilithium) to ensure quantum-resilient and tamper-proof deepfake detection. It achieves superior accuracy and robustness for real-world applications.
The DeepQShield framework utilizes a ResNeXt-50 CNN as its backbone, chosen for its modularity and efficiency in learning subtle image manipulations. This is fortified with lattice-based adversarial training, incorporating Learning with Errors (LWE) to introduce structured noise, making the model resilient against both classical and quantum adversarial attacks. Post-quantum cryptographic safeguards, specifically Kyber for key exchange and Dilithium for digital signatures, are integrated to ensure the authenticity and integrity of detection results. This layered defense mechanism ensures robust performance even under advanced adversarial conditions.
DeepQShield demonstrates exceptional performance, achieving a high accuracy of 99.28% and an AUC score of 0.9997 on the challenging Deepfake Detection Challenge (DFDC) dataset. This significantly surpasses conventional models like EfficientNet-B7 (97.2% accuracy) and Vision Transformers (90-98% accuracy). The framework also maintains efficient inference speeds, averaging around 15.20 ms per image on GPU, making it suitable for real-time deployment in various enterprise scenarios.
A core innovation of DeepQShield lies in its quantum-resilient security. By embedding lattice-based adversarial training, the model inherently resists quantum computing-powered attacks. The integration of Kyber-1024 ensures secure, quantum-safe key exchange, while Dilithium-5 provides robust digital signatures for verifying detection results. This hybrid cryptographic approach safeguards data integrity and authenticity, making the system future-proof against emerging quantum threats in forensic and sensitive applications.

Case Study: Securing Digital Evidence for Legal Forensics
A legal firm required irrefutable verification of video evidence submitted in a high-profile case, where deepfake manipulation was suspected. Traditional forensic tools struggled to provide conclusive proof against sophisticated adversarial alterations. Leveraging DeepQShield, the firm was able to:
- Accurately detect subtle deepfake manipulations with 99.28% confidence, even when modified by LWE-based adversarial attacks.
- Generate digitally signed and encrypted detection reports using Kyber and Dilithium, ensuring tamper-proof integrity and non-repudiation of findings.
- Provide court-admissible evidence with verifiable cryptographic proofs, establishing a new standard for digital forensics.
This implementation not only secured the case's outcome but also set a precedent for quantum-resilient evidence authentication in the legal sector, dramatically reducing investigation time and increasing trust in digital media.
