In this paper, a robust watermarking method based on modifying the DC component of the DCT coefficient is presented. A random generated key sequence is embedded into the DC coefficients of 8x8 blocks with a scaling factor. Effect of the scaling factor under several attacks is evaluated. Experiments show that the method is robust without losing the transparency.
