| TITLE | An Explainable AI Method for Detecting Fake Facial Images |
|---|---|
| ABSTRACT | The rapid advancement of generative adversarial networks and diffusion-based image synthesis has produced synthetic facial images visually indistinguishable from authentic photographs, creating serious threats to digital identity, media integrity, and public trust. Existing detection approaches suffer from two critical limitations: inadequate sensitivity to color-space artifacts when processing standard RGB images, and a black-box decision-making process that prevents forensic analysts and legal professionals from validating classification outcomes. This study addresses both limitations by proposing a deepfake facial image detection framework integrating MTCNN-based face detection and geometric alignment to ensure the classifier focuses exclusively on forensically relevant facial content rather than background noise, LAB color space transformation to decouple luminance from chrominance and surface subtle generation artifacts characteristic of synthesized faces, fine-tuned InceptionResNetV2 classification, and LIME-based superpixel attribution maps highlighting suspicious facial zones including skin-hair boundaries, periocular regions, and dentition areas. The framework was trained on the 140k Real and Fake Faces dataset using an 80/10/10 split on a GPU-enabled environment. The proposed pipeline achieved a test accuracy of 98.93%, generalization accuracy of 96.94%, with good precision, recall and F1-score, outperforming the baseline RGB model across every evaluated metric, with demonstrated real-time deployability through a Flask web application. |
