Abstract

Deepfakes, synthetic pieces of media, have taken over our online ecosystem in recent years, posing a significant threat to our digital security. This paper discusses the idea of implementing a log-based fourier transformation for deepfake detection. By converting images to the frequency domain during preprocessing, the transformation highlights subtle imbalances across the pixel patterns of deep fake images. Experimental results show noticeable changes in transformed deepfakes. Further research measured high accuracy for models trained and tested on frequency images. In conclusion, these results show a promising future for frequency analysis, at the forefront in deepfake detection.
