A Transfer-Learning Approach for Detection of Multiclass Synthetic Skin Cancer Images Generated by Deep Generative Models to Prevent Medical Insurance Fraud
Artificial Intelligence is advancing rapidly, raising critical concerns about the integrity of digital content, particularly in sensitive domains such as medical imaging. Recent AI techniques, such as Generative Adversarial Networks (GANs) and diffusion models, can generate highly realistic synthetic medical images, posing risks of misdiagnosis, inappropriate treatment, and other adverse outcomes. This paper presents a deep learning-based approach to distinguish between authentic and synthetic images of skin malignancies generated by DCGAN, Wasserstein GAN (WGAN), and Stable Diffusion. A comprehensive dataset was constructed using authentic malignant skin images from an open-source Kaggle repository, alongside artificially generated images. Multiple deep learning models were trained and evaluated, with DenseNet169 achieving the highest performance, reaching 99.67% training accuracy, 97.50% validation accuracy, and 98.50% test accuracy—along with substantial precision, recall, and F1 scores across all classes. These results demonstrate the model's efficacy in identifying both real and fake medical images. This work contributes to the emerging field of medical image forensics, highlighting its potential integration into clinical and insurance workflows to prevent fraud, strengthen trust, and mitigate risks. Furthermore, it lays the groundwork for future studies involving larger datasets, additional Deepfake generation methods, and real-time clinical applications.

Introduction
This section sets the stage by discussing the rapid advancement of AI, particularly in medical imaging, and the risks associated with AI-generated synthetic images, such as misdiagnosis and insurance fraud. It introduces Generative Adversarial Networks (GANs) and diffusion models as key technologies enabling this, and outlines the paper's objectives to detect multiclass synthetic skin cancer images.
Methodology
This section details the approach, starting with dataset construction from real malignant skin images and synthetic images generated by DCGAN, WGAN, and Stable Diffusion. It covers data preprocessing, including resizing, normalization, and augmentation, and introduces the proposed fine-tuned DenseNet169 model as the primary classification architecture, explaining its dense connectivity and custom classification head.
Results & Discussion
Here, the paper presents the experimental outcomes, evaluating the DenseNet169 model using accuracy, precision, recall, F1-score, and confusion matrices. It highlights DenseNet169's strong performance in distinguishing real from synthetic images, achieving 98.50% test accuracy, and compares these results with state-of-the-art studies, emphasizing the multiclass nature of this work.
Practical Implications
This part discusses the real-world impact of the research, focusing on how the deep learning framework can enhance healthcare efficiency by validating diagnostic images, guiding institutions in securing medical databases, mitigating adversarial attacks on AI diagnostics, and aiding medical forensics in legal and insurance contexts to prevent fraud and strengthen trust.
Limitations & Future Work
The authors acknowledge the study's limitations, such as reliance on synthetic images that may not fully represent real-world deepfakes, restricted scope to dermoscopic skin lesion images, and the need for larger, multi-center clinical datasets. Future work aims to address these by extending the approach to multiple imaging modalities and evaluating robustness against advanced generative models.
Conclusion
The study concludes by affirming the feasibility and effectiveness of a fine-tuned DenseNet169 model for forensic detection of synthetic medical images. It emphasizes that AI-generated images exhibit detectable artifacts useful for forensic identification and that the multiclass approach provides granular information, contributing to preventing fraud, enhancing trust, and laying groundwork for future research.

Preventing Medical Insurance Fraud with AI Forensics
The proposed deep learning framework for identifying multiclass synthesized medical images has several potential applications in enhancing healthcare efficiency. It can become part of the clinical process, enhancing the validity of diagnostic imaging by scanning manipulated or synthetic images that may lead to erroneous diagnoses. The model could provide guidance to medical institutions and regulatory agencies on developing secure and trustworthy medical image databases, particularly for telemedicine and electronic health records. Additionally, the research helps mitigate the risk of adversarial attacks on AI-driven healthcare applications, thereby enhancing the resilience and confidence of automated diagnostic tools. Lastly, the technique is also beneficial in medical forensics, as it helps determine whether an image is authentic or has been altered in legal proceedings or insurance claims. By demonstrating a high-performing detection framework with an accuracy of 98.50%, these studies enhance trust in the safety and integrity of medical records and lay the groundwork for future research involving datasets, multiple modalities, and advanced generative models.
