Abstract Nowadays, with the proliferation of mobile devices and the internet around the world that are available for everyone, and due to the low prices versus their high capabilities, images are considered one of the most common ways of transmitting information between users, advancement of image processing and editing tools, simplified the process of editing and changing photographs such as in magazines, newspapers, scientific journals, and on social media or on the Internet. As a result, the propagation of manipulated photographs that misrepresent the truth is prevalent, whether deliberate or inadvertent. We propose a method that uses deep learning based convolutional neural network in order to detect instances of the copy-move forgeries in images which can help to ensure data authenticity in digital forensic investigations. In this case, our method is intended to improve digital evidence integrity by detecting complicated changes quickly and precisely. This work can supports cybersecurity applications like anti-fraud systems, fake news detection, and social media forensics. The findings of the experiment demonstrate that the suggested approach is capable of detecting forgery against multiple copies and post-processing activities. The dataset's images used for both training and testing are MICC-F2000, composed of 2,000 images, 700 tamper and 1,300 originals. The findings indicate a testing accuracy of 98.00% and a training accuracy of 99.17%.
