We represent the spatially periodic inter-pixel correlation due to color filter array interpolation in a quadratic form. Based on this, a coefficient matrix is obtained for each color channel, whose principal components are extracted and fed to feed-forward back propagation networks for source camera identification. Experiments demonstrate the efficacy, sensitivity and robustness of our method
