During the image tampering, contrast enhancement operation is often used to highlight some information, weaken or remove some unwanted information in images. However, this operation simultaneously leaves specific fingerprints in the image's pixel value histogram. This paper presents a wavelet analysis method to detect tampering image. We firstly convert the RGB color space into YCbCr color space, and extract the Y monochrome channel image; secondly, the normalized energy is calculated in the wavelet details sub-bands after wavelet transform of image's pixel value histogram of the component; finally, the altered image will be identified according to the normalized energy. The contrast...
