“…À critério de curiosidade, na literatura mais recente de detecc ¸ão de deepfakes, usando as bases Celeb-df e Faceforencis++, observa-se que os autores [Mohiuddin et al 2023] criaram um modelo de machine learning que usa a técnica de selec ¸ão das características hierárquicas, para comparar a acurácia desse modelo em cada base de dados, seja Celeb-DF ou Faceforencis++, em relac ¸ão a outras literaturas. [Mohiuddin et al 2023] utilizaram 1.416 frames reais e 9.262 fakes para Celeb-DF. Já para o Faceforencis, os autores contaram com 3.294 frames reais e 3.176 fakes.…”

“…Em ambas as bases de dados, todos os frames foram divididos em treino, validac ¸ão e teste. Ao longo do trabalho, [Mohiuddin et al 2023] descobriram a acurácia de 99,35% e 99,16% para ambas as bases de dados, respectivamente. Diferentemente dessa literatura, pode observar, portanto, que a principal vantagem deste estudo é a pesquisa com um conjunto limitado de amostras e com acurácias encontradas no Sobel semelhantes a esse modelo.…”

Through artificial intelligence (AI) techniques, deepfakes (deep learning + fakes) are created. Currently, almost six years after this topic's popularization, some people have been using AI algorithms to change, for example, face. In this scenario, this article proposes to identify the most discriminating characteristics, based on the multivariate statistical learning techniques, with and without the Sobel filter. Complementarily, we aim to analyze the areas that humans have visually identified as relevant to detect a deepfake. The results show that the statistical model (PCA plus MLDA) combined with the Sobel filter correctly classified most of the images, highlighting the regions that discriminate a deepfake.

In recent years, the proliferation of deep learning (DL) techniques has given rise to a significant challenge in the form of deepfake videos, posing a grave threat to the authenticity of media content. With the rapid advancement of DL technology, the creation of convincingly realistic deepfake videos has become increasingly prevalent, raising serious concerns about the potential misuse of such content. Deepfakes have the potential to undermine trust in visual media, with implications for fields as diverse as journalism, entertainment, and security. This study presents an innovative solution by harnessing blockchain-based federated learning (FL) to address this issue, focusing on preserving data source anonymity. The approach combines the strengths of SegCaps and convolutional neural network (CNN) methods for improved image feature extraction, followed by capsule network (CN) training to enhance generalization. A novel data normalization technique is introduced to tackle data heterogeneity stemming from diverse global data sources. Moreover, transfer learning (TL) and preprocessing methods are deployed to elevate DL performance. These efforts culminate in collaborative global model training zfacilitated by blockchain and FL while maintaining the utmost confidentiality of data sources. The effectiveness of our methodology is rigorously tested and validated through extensive experiments. These experiments reveal a substantial improvement in accuracy, with an impressive average increase of 6.6% compared to six benchmark models. Furthermore, our approach demonstrates a 5.1% enhancement in the area under the curve (AUC) metric, underscoring its ability to outperform existing detection methods. These results substantiate the effectiveness of our proposed solution in countering the proliferation of deepfake content. In conclusion, our innovative approach represents a promising avenue for advancing deepfake detection. By leveraging existing data resources and the power of FL and blockchain technology, we address a critical need for media authenticity and security. As the threat of deepfake videos continues to grow, our comprehensive solution provides an effective means to protect the integrity and trustworthiness of visual media, with far-reaching implications for both industry and society. This work stands as a significant step toward countering the deepfake menace and preserving the authenticity of visual content in a rapidly evolving digital landscape.
