Abstract :
A novel blind digital image watermarking algorithm based on multi strategy is put forward in this paper. The watermark is embedded in multi-resolution wavelet transform domain of the original image. Based on spread spectrum techniques, the algorithm is composed of new technique to improve robustness, imperceptibility and security. In this technique, we interlace several copies of watermark in different resolution to embed in wavelet transform domain. As a result the recovered watermark is shown better performance after various attacks.
