Embedding Error Based Data Hiding in Color Images for Distortion Tolerance

In this paper, a data hiding scheme with distortion tolerance for color image is proposed. Data hiding is used to embed secret information into the cover image for secure transmission and protecting copyright. The secret information feasibly a text or an image. To protect the copyright of a true color image, a signature (a watermark), which is represented by a sequence of binary data, is embedded in the color image. In this proposed scheme, we first calculate the embedding error between the cover image and the secret information. Based on this embedding error, the stego image is computed then the embedded data are extracted by the extraction procedure. This scheme can tolerate some distortion such us salt and pepper noise, Gaussian noise, uniform noise, and JPEG lossy compression when transmitting a stego image through any network. Experimental results and discussions reveal that the proposed scheme tolerates those distortions with acceptable image quality
