Source-destination discrimination on copy-move forgeries

Multimedia Tools and Applications, 2021
Since digital images are one of the most important carriers of information, their authenticity is quite important. There are miscellaneous forgery techniques for manipulating digital images, and one of those is copy-move forgery. Many forgery detection techniques have been developed for detection of copy-move forgery so far.

Accurate And Efficient Copy-Move Forgery Detection

2019 9th International Conference on Advances in Computing and Communication (ICACC), 2019
Today, due to the development of image processing applications like GIMP and Photoshop, forging of digital images with the absence of any trace is not at all difficult. Therefore crucial validation of content in a digital image is essential. Among the many prevailing forgery techniques, the copy-move forgery is recurrently occurring and it is easily ...

Passive copy-move forgery detection in videos

2014 International Conference on Computer and Communication Technology (ICCCT), 2014
Due to evolution of prevalent sophisticated digital video editing software it has become easier to forge any video. Copy-Move forgery is a special kind of video forgery technique, in which copy-move of the frame region is performed in intra frame or inter frames.

Copy-Move Forgery Detection Using Cellular Automata

2014
Thanks to the availability of many sophisticated image processing tools, digital image forgery is prevalent nowadays. One of the common methods is copymove forgery (CMF), where part of an image is copied to another location in the same image. Detection of copy-move forgery has been widely researched recently, and many different solutions have been ...

Efficient Dense-Field Copy–Move Forgery Detection

IEEE Transactions on Information Forensics and Security, 2015
We propose a new algorithm for the accurate detection and localization of copy–move forgeries, based on rotation-invariant features computed densely on the image. Dense-field techniques proposed in the literature guarantee a superior performance with respect to their keypoint-based counterparts, at the price of a much higher processing time, mostly due

Rotation invariant copy move forgery detection method

2015 9th International Conference on Electrical and Electronics Engineering (ELECO), 2015
In recent years, due to the increment in the image editing software applications and the easiness of using these, the probability of malicious changes on the images has also increased. Copy-move forgery is one of the most widely applied modification types on the images. In case of that the copied region is rotated before being pasted, forgery detection

Copy-Move Forgery Detection Methods: A Critique

2020
With the advancement of image editing tools, legitimacy and creditability of the images are put in jeopardy. There are various types of image forgeries techniques like splicing, retouching, false captioning, and copy-move. But the most predominant forgery techniques are splicing and copy-move forgery. In copy-move forgery, a part of the image is copied

Security of copy-move forgery detection techniques

2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011
Copy-move forgery is a specific form of image tampering, where a part of a digital image is copied and pasted into a different part of the same image. There are many copy-move forgery detection techniques, but their security has not been examined in detail. In this paper, we analyze the robustness and security of the detection techniques of Fridrich [1]

Copy move forgery detection based on LBP

2013 21st Signal Processing and Communications Applications Conference (SIU), 2013
Increase on the availability of the image editing tools makes it easy to create digital forgeries. More popular forgery in image manipulation is the copy move forgery where part of an image is copied into another location to hide an object. The methods that are used to detect the copy move forgery in images have a drawback. Length of the feature vector

Copy-move forgery detection using improved SIFT

SPIE Proceedings, 2016
There are various forgeries in digital images without leaving any obvious traces of tampering due to powerful image processing and editing software. Copy-move forgery is a common type of image forgery in which a part of digital image is copied and pasted to another part in the same image with the intent of disguising some details.
