Fast Copy-Move Detection of Digital Audio
2017 IEEE Second International Conference on Data Science in Cyberspace (DSC), 2017Audio forgery is a critical part of digital forgery. There is a large variety of audio forgery forms, and copy-move is one of the most common but effective one. Merely one word's copy-move can turn the whole sentence into distinct meaning. So the way to detect this form of forgery precisely and effectively is especially useful and significant in the ...

An efficient model for copy-move image forgery detection
International Journal of Web Information Systems, 2022Purpose This study aims to solve problems of detecting copy-move images. With input images, the problem aims to: Confirm the original or forgery of the images, evaluate the performance of the detection and compare the proposed method’s effectiveness to the related ones.

Copy-Move Forgery Detection Using DyWT
International Journal of Multimedia Data Engineering and Management, 2017In this paper, we proposed a passive method for copy-move region duplication detection using dyadic wavelet transform (DyWT). DyWT is better than discrete wavelet transform (DWT) for data analysis as it is shift invariant. Initially we decompose the input image into approximation (LL1) and detail (HH1) sub-bands.

An Efficient Detection Algorithm for Copy-Move Forgery
2015 10th Asia Joint Conference on Information Security, 2015The most common method of tampering with a digital image is copy-move forgery, in which a part of an image is duplicated and used to substitute another part of the same image at a different location. In this paper, we present an efficient and robust method to detect such artifacts.

Copy Move Forgery Detection based on double matching
Journal of Visual Communication and Image Representation, 2021Abstract Copy Move is a technique widespreadly used in digital image tampering, meaning Copy Move Forgery Detection (CMFD) is still a significant research. In this paper, a novel CMFD method is proposed, including double matching process and region localizing process.

Rotation robust detection of copy-move forgery
2010 IEEE International Conference on Image Processing, 2010Copy-move tampering is a common type of image synthesizing, where a part of an image is copied and pasted to another place to add or remove an object. In this paper, an efficient algorithm based on the Fourier-Mellin Transform is proposed with features extracted along radius direction. Also, to reduce computational cost, a link processing is introduced

Copy-move forgery detection based on multifractals
Multimedia Tools and Applications, 2019Digital images and video are the basic media for communication nowadays. They are used as authenticated proofs or corroboratory evidence in different areas like: forensic studies, law enforcement, journalism and others. With development of software for editing digital images, it has become very easy to change image content, add or remove important ...

Copy-move forgery detection based on PatchMatch
2014 IEEE International Conference on Image Processing (ICIP), 2014In this work we propose a new algorithm for copy-move forgery detection and localization, based on the fast computation of a dense nearest-neighbor field. To this end, we use PatchMatch, an iterative randomized algorithm for nearest-neighbor search, which exploits the regularity of natural images to converge very rapidly to a near-optimal and smooth ...

Copy-Move Forgery Detection in Digital Image
2009Digital images are easy to be tempered and edited due to availability of image editing software. The most common ways to temper a digital image is copy-paste forgery which is used to conceal objects or produce a non-existing scene. To detect the copy-paste forgery, we divide the image into blocks as the basic feature for detection, and transfer every ...

An efficient and robust method for detecting copy-move forgery
2009 IEEE International Conference on Acoustics, Speech and Signal Processing, 2009Copy-move forgery is a specific type of image tampering, where a part of the image is copied and pasted on another part of the same image. In this paper, we propose a new approach for detecting copy-move forgery in digital images, which is considerably more robust to lossy compression, scaling and rotation type of manipulations.
