Challenges of Face Image Authentication and Suggested Solutions

The rapid development of face image manipulation algorithms and the distribution of their easy-to-use applications bring an urgent need to manipulation detection techniques that can reveal the modification in face image and prove its authenticity. Recently, the term “DeepFakes” and their detection techniques have attracted the attention of the research community. To current date, there is no universal detection technique and each one has its own limitations. In this paper, a brief review of face image manipulation techniques and their detection is presented followed by a summary of the limitations and challenges that can face the manipulation detection techniques. Then, the paper presents some suggestions which can be considered for future researches in this attracted and interesting research topic. The review in this paper can be considered as a starting point for the researchers who are concerned about this research field.
