Copy-move forgery detection from printed images
, 2014 Counterfeiting digital images through a copy-move forgery is one of the most common ways of manipulating the semantic content of a picture, whereby a portion of the image is copy-pasted elsewhere into the same image.

Pyramid structure for copy-move forgery detection
, 2016 碩士本論文提出一個被動式偵測影像是否遭到複製移動竄改的方法，不需原本未經竄改的影像也能夠偵測出被複製移動竄改的區塊，在一被複製移動竄改的影像中，假設在此影像中被複製移動竄改的區域為大於限定的範圍，對影像進行區塊分割，計算區塊中相互之間的關係，得到被竄改區域中的部分區塊，再藉由這些部分區塊往周圍以金字塔結構進行區塊比對至偵測被竄改區域的所有部分，此方法可降低影像中區塊之間比對的時間及次數。相較其他學者所提出的偵測方法，本論文之偵測方法相較於地毯式偵測的相同條件下，能有一樣的結果但大幅減少執行時間。This

Copy-Move Forgery Detection in Digital Image
, 2012 [[abstract]]Copy-move forgery is a specific type of image tampering where a part of the image is copied and pasted somewhere else in the image with the intent to cover an important image feature.

An Audio Copy-Move Forgery Localization Model by CNN-Based Spectral Analysis
Applied SciencesIn audio copy-move forgery forensics, existing traditional methods typically first segment audio into voiced and silent segments, then compute the similarity between voiced segments to detect and locate forged segments.

Fuzzy Based Image Forensic Tool for Detection and Classification of Image Cloning
International Journal of Computational Intelligence Systems, 2016 With the easy availability of image processing and image editing tools, the cases of forgery have been raised in the last few years. Now days it is very difficult for a viewer and judicial authorities to verify authenticate a digital image.

Copy-Move Forgery Detection Based on Keypoint Clustering and Similar Neighborhood Search Algorithm
IEEE Access, 2020 Copy-move is one of the most commonly used methods of tampering with digital images. Keypoint-based detection is recognized as effective in copy-move forgery detection (CMFD). This paper proposes an efficient CMFD method via clustering SIFT keypoints and
