Abstract
This paper adopts the Shannon entropy algorithm to search the optimal wavelet packet from bottom to up, and decomposes the original image and watermark respectively with wavelet packet, and finally embeds the watermark data into the selected basis of wavelet packet of the original image. This invisible watermarking verified by experiments indicates that it is robust and it remains image of high quality.
