Multiple Fusion Strategies in Localization of Local Deformation Tampering
International Journal of Digital Crime and Forensics, 2021 Tampering with images may involve the field of crime and also bring problems such as incorrect values to the public. Image local deformation is one of the most common image tampering methods, where the original texture features and the correlation between the pixels of an image are changed.

Robust Hash for Detecting and Localizing Image Tampering [PDF]
2007 IEEE International Conference on Image Processing, 2007 An image hash should be (1) robust to allowable operations and (2) sensitive to illegal manipulations and distinct queries. Some applications also require the hash to be able to localize image tampering. This requires the hash to contain both robust content and alignment information to meet the above criterion.

Transferable Adversarial Attack on Image Tampering Localization
CoRR, 2023 It is significant to evaluate the security of existing digital image tampering localization algorithms in real-world applications. In this paper, we propose an adversarial attack scheme to reveal the reliability of such tampering localizers, which would be fooled and fail to predict altered regions correctly.
