Abstract
Copyright information is modulated and embedded into the wavelet domain of original image of digital literature in digital library with generalized matched filter receiver (GMFR), which is an optimum receiver. Because of the good performances of de-noising and whitening to non-stationary noise of wavelet transformation, a GMFR scheme of copyright protection for digital library only can be detected by authorized people. Numerical results show that the proposed copyright protector with GMFR in wavelet domain is effect and is also better than some traditional methods.
