SIFT-Symmetry: A robust detection method for copy-move forgery with reflection attack.

•CMF detection with rotation and scale as well as reflection-based attack is studied.•The purpose is to achieve high robustness against CMF with reflection and any combination attacks.•SIFT-Symmetry is a combination of SIFT-based CMF detection with symmetry-based matching.•SIFT-Symmetry is evaluated on two new datasets and compared with three methods.•SIFT-Symmetry’s F-score is superior than other existing methods.
