Using the Wavelet as the Private Key for Encrypting the Watermark

Watermarking is an effective approach to the copyright protection of digital media such as audio,image,and video.By inspriation from cryptography and considering the immensity of the set of all possible wvaelets,it is presented that in wavelet domain watermarking,the associated wavelet can be considered as the private key for encrypting the wavtermark so as to enhance the security of the embedded mark.This idea is partly supported by the fact that from computational complexity viewpoint.It is very time-consuming to search over the immense set of all candidate wavelets for the right one if no a priori knowledge is known about it .To verify our proposal,the standard image“Lena”is first watermarked in a specific wavelet domain,the watermark recovery experiments are then conducted in the wavelet domain for a set of wavelets with the one used for mark embedded in it ,separately.It follows from the experimetal results that the mark can be recovered only in the right wavelet domain,which jusstifies the suggestion.
