Abstract

In this paper, we describe a technique to detect image tampering using two different methods. The first is based on the Bayer interpolation process and its consequences in the Fourier domain. The second uses artifacts of the JPEG compression and more particularly in the JPEG frame observable in the Fourier domain.
