Description: Frequency-domain digital watermarking method by adding the principle is that first of all, the original signal (voice signal of one-dimensional, two-dimensional image signal) to frequency domain transformation, commonly used in general transform DWT, DCT, DFT, WP and fractal. Then, adding the watermark information signal to the frequency domain inverse transform (IDWT, IDCT, DFT, WP), received signal containing the watermark information.
