  Abstract

Digital watermarking is to embed imperceptible mark into image, video, audio and text data to prevent the illegal copy of multimedia data, arbitrary modification, and also illegal sales of the copies without agreement of copyright ownership. The DCT(Discrete Cosine Transforms) transforms of original image is conducted in this research and these DCT coefficients are expanded by Fourier series expansion algorithm. In order to embed the imperceptible and robust watermark, the Fourier coefficients(lower frequency coefficients) can be calculated using sine and cosine function which have a complete orthogonal basis function, and the watermark is embedded into these coefficients. In the experiment, we can show robustness with respect to image distortion such as JPEG compression, blurring and adding uniform noise. The correlation coefficient are in the range from 0.5467 to 0.9507.
