Abstract
With the development of cyber security and multimedia forensics, digital image manipulation has recently been recognized
as one of the major challenges in forensic image analysis. Therefore, selecting an image area and then copying and
pasting it into the same image is the hardest process in passive image forgery. This act violates privacy and secrecy of
authenticity of digital image. The attacker exploits the available tools of editing image program to make the fake image
similar to the original one. This paper presents a proposed fast and efficient passive Copy-move forgery detection scheme.
Hessian- Affine and Harris-Affine detectors, and Shift Invariant Feature Transform (SIFT) descriptor, are employed
in the proposed scheme. These detectors provide sufficient key points for detecting the duplicated regions in the case
of small or invisible regions. The experimental results show that the proposed scheme is invariant against simple and
hard attacks like uniform or non-uniform transformation. The proposed scheme was evaluated using standard data sets
(GRIP, MICC 220, and F8 Multi). Resulted True Positive Rate (TPR) was 0.98 and False Positive Rate (FPR) was 0.035.
Thus, the scheme is effective and providing valuable results compared to recent passive image authentication schemes.
