Abstract	In the paper, a new method for semi-fragile watermarking of color image based on Slant Transform and channel coding is proposed. This technique certifies the belongings of images by using authentication watermarks that are embedded in IF of Slant Transform regions. Recover manipulated regions by restore watermarks that are extracted from the former 11 coefficients of each block. Restore watermarks are embedded in the least significant bits of each pixels. For increasing robustness of the algorithm, calculate error correction coding and spread spectrum modulation to authentication watermarks before embedding them. Watermarking extraction does not need original image, it belongs to blind extraction.
