Abstract :
The advent of digital forensic techniques imposes great challenges to the security of image disguise where tampering is involved to conceal the existence of sensitive objects in the source image. As a consequence, image interpolation that is a prerequisite step in image disguise should be adapted to be forensic resistant. This paper proposes a novel and secure interpolation method to facilitate image disguise. As it is reported in the literature, the trace of interpolation can be detected by exploiting the linear relationship among pixels. Therefore, forensic resistant is achieved in this work by breaking the linear relationship among pixels. In particular, genetic algorithm is employed make a balance between forensic resistance and the visual quality of the tampered image.
