Hybrid Deep Learning Framework
This research introduces a novel two-phase framework for image forgery detection. Phase 1 focuses on building a robust design domain dictionary through extensive data augmentation and adversarial training. Phase 2 implements a hybrid classification system, combining a pre-trained Vision Transformer (ViT) for advanced feature extraction and a Support Vector Machine (SVM) for efficient binary classification. This architecture aims to deliver high accuracy and strong resilience against diverse image manipulations.
Enhanced Data & Adversarial Resilience
A cornerstone of this framework is the rigorous dataset preparation. Data augmentation techniques, including rotation, translation, scaling, flipping, and shearing, were applied to significantly expand training diversity and improve model generalization. Crucially, adversarial training, specifically using Patch-Fool attacks, was implemented to force the model to learn features robust to small, targeted perturbations, greatly enhancing its resilience against malicious attacks and real-world deployment challenges.
Synergistic ViT and SVM Integration
The hybrid architecture strategically leverages the strengths of both Vision Transformers and Support Vector Machines. A pre-trained ViT-B-16 model, pre-trained on ImageNet-1k, is utilized solely for its powerful feature extraction capabilities, capturing rich semantic and spatial cues from images. These high-dimensional features (768-D) are then fed into an SVM with an RBF kernel for classification. This approach combines the ViT's deep understanding of image properties with SVM's efficiency and robustness in high-dimensional spaces, avoiding the computational overhead of end-to-end ViT fine-tuning.
Validated Performance & Robustness
The framework underwent comprehensive evaluation across five standard forensic datasets (CASIA v1.0, CASIA v2.0, MICC-F220, MICC-F2000, MICC-F600) and a merged dataset. With data augmentation and adversarial training, it achieved an impressive 99.23% accuracy and 98.06% F1-score on the merged dataset. It demonstrated strong resilience against Patch-Fool attacks, maintaining 98.2% accuracy on CASIA v1.0 even under attack, highlighting its superior performance compared to existing CNN and standalone ViT methods.
Future Directions for Evolution
While highly effective, the framework acknowledges limitations. Current work focuses on copy-move and splicing forgeries; future efforts will expand to include AI-generated content (deepfakes, GANs). Computational overhead for adversarial training remains a scalability consideration. Additionally, generalization to large-scale social media images with complex real-world degradations requires further validation. Future research will explore advanced defensive mechanisms and video forgery detection.

Enterprise Application: Securing Digital Content in Media & Forensics
A global news agency faces the challenge of rampant digital image manipulation, leading to reputational damage and compromised journalistic integrity. Implementing the Hybrid ViT-SVM framework allows them to automatically detect sophisticated copy-move and splicing forgeries with over 99% accuracy. By integrating this AI solution into their content verification pipeline, the agency can rapidly authenticate visual media before publication, safeguarding their credibility and public trust. The framework's robustness against adversarial attacks ensures that even subtly altered images designed to bypass detection are identified, providing a critical layer of defense against misinformation campaigns.
Similarly, a digital forensics firm uses this technology to expedite evidence analysis. The efficient feature extraction and classification capabilities significantly reduce the manual effort required to identify manipulated digital evidence, streamlining investigations and enhancing the reliability of legal proceedings. This translates to faster case resolution and a higher conviction rate, proving the tangible ROI of advanced AI in high-stakes environments.
