Abstract
This paper adopt the Shannon entropy algorithm to search the optimal wavelet packet from bottom to up, and decompose the original image and watermark respectively with wavelet packet, and finally embed the watermark data into the selected basis of wavelet packet of the original image. The experiments against attack show that the watermark created by the algorithm is invisible, and image quality have been well preserved, and strong robustness have been shown at same time.
