A survey on tamper detection techniques for digital images

الملخص EN

Recently, fake and fabricated images that have been manipulated for several purposes, including cosmetic and some for illegal purposes, have spread on social media.

And because this is not an easy matter, it has become necessary for researchers in this field to search and investigate the types of images, to verify their authenticity and how to manipulate them.

Therefore, the aim of this research is to serve as an assistant to the researcher who wants to enter this field.

In this research, a survey of the types of forgery was presented with examples.

The most important common methods for detecting forgery were also presented, and the previous studies that contributed to the process of detecting fraud, both traditional detection and deep learning-based detection, were highlighted, while giving the most important strengths and weaknesses of both types.

We note from this that detecting the forgery process is a difficult process and takes time to detect the changes that have been made to the image that cannot be detected by the naked eye.

In this research, researchers have been urged to go towards deep learning for the purpose of detecting the forgery of the features that it enjoys.
