- W2378830650 abstract "The digital watermark technology is embedding the copyright information into the multimedia data through the specific algorithm and not affecting the use value of the original media. The embedded information can be withdrawn through the special-purpose detector, which can realize the applications of copyright protection, interpolation examination and so on. This paper has analyzed the concept and characteristics of digital watermark technology, studied the wavelet transformation application in the digital watermark, realized a kind of DWT spread spectrum watermark technology, and carried on the implementation of the corresponding algorithm. Simulation results of the algorithm show that the method has strong robustness when experience attack such as noise, filter, cutting and JPEG, and we can extract clear watermark after that." @default.
