| Abstract: | With the development of network technology and digitol technique, the watermarking has the applied prospect broadly in the fields such as copyright protection, data discriminating ,digital product attestation. The paper introduces digital water marking＇s basic theories and selects the discrete cosine transform （DCT） algorithm to digital watermarking embedding and the extraction in the MATLAB environment. |
