Double image compression might occur if the image has been tampered with or embedded into secret data. It is essential to detect double compression for image forensics and blind steganalysis. This paper analyzes the statistical difference in the sub-band DWT (discrete wavelet transform) coefficient histograms between single and double JPEG 2000 compression; devises a scheme to discriminate between them. The experiments demonstrate that the proposed approach can achieve an effective and accurate detection for double JPEG 2000 compression.
