DWT image watermarking algorithm based on scrambling algorithm

The paper proposes an image watermarking Algorithm based on DWT transform. Utilizing Human visual system, this Algorithm scrambles the watermarking image, and puts the watermarking image and original image in three layers wavelet transform, eventually embeds the watermarking image in the original image to realize the embedding of watermarking. The test has shown that the Algorithm has the advantages of good concealment and robustness.
