Due to availability of powerful image processing software and improvement of human computer knowledge, it becomes easy to tamper images. Manipulation of digital images in different fields like court of law and medical imaging create a serious problem nowadays. Copy-move forgery is one of the most common types of forgery which copies some part of the image and pastes it to another part of the sa...

The problem of signature verification is in theory a pattern recognition task used to discriminate two classes, original and forgery signatures. Even after many efforts in order to develop new verification techniques for static signature verification, the influence of the forgery types has not been extensively studied. This paper reports the contribution to signature verification considering di...

Today manipulation of digital images has become easy due to powerful computers, advanced photo-editing software packages and high resolution capturing devices. Verifying the integrity of images and detecting traces of tampering without requiring extra prior knowledge of the image content or any embedded watermarks is an important research field. An attempt is made to survey the recent developme...

In the current times the extent of video forgery has inflated on the web with the rise within the role of malware that has created it doable for any user to transfer, transfer and share objects on-line together with audio, images, and video. Specifically, Video Editor and Adobe Photoshop square measure a number of the multimedia system software package and tools that square measure accustomed e...

In this paper, we proposed a new fast detection method of copy-move forgery image using two step search algorithm in the spatial domain. We proposed a new two step search algorithm for copy-moved forgery image detection. The performance of the proposed method is experimented on several forged images. Our two step search algorithm reduced 96.82% computational complexity more than conventional al...

Image forgery identification assumes a fundamental part in criminological science, the vast majority of the created strategies are concentrating on coarse grained fabrication restriction. In this paper, we introduce forgery detection method based on artifacts obtained by Color Filter Array (CFA) which are used in most digital cameras. Here we make the assumption that forgery removes the artifac...

Image editing techniques enable people to modify the content of an image without leaving visual traces and thus may cause serious security risks. Hence detection localization these forgeries become quite necessary challenging. Furthermore, unlike other tasks with extensive data, there is usually a lack annotated forged images for training due annotation difficulties. In this paper, we propose s...

Signatures are one of the most important techniques for biometric authentication. There two kinds signature nowadays, offline(static) and dynamic (online). greater distinctive characteristics offline signatures, but there less signatures. Offline signatures also harder to check. Furthermore, significant downside is that even talented signer does not sign same way. This called Intra-personal var...
