Blind Detection of Copy-Move Forgery in Digital Audio Forensics
IEEE Access, 2017 Although copy-move forgery is one of the most common fabrication techniques, blind detection of such tampering in digital audio is mostly unexplored. Unlike active techniques, blind forgery detection is challenging, because it does not embed a watermark ...

Fusion of block and keypoints based approaches for effective copy-move image forgery detection [PDF]
, 2016 Keypoint-based and block-based methods are two main categories of techniques for detecting copy-move forged images, one of the most common digital image forgery schemes. In general, block-based methods suffer from high computational cost due to the large
