Abstract: We combines the advantages of second-generation wavelet transform and the traditional image watermarking method using wavelet multiresolution transform, proposing a scheme of images watermarking based on second-generation wavelet transform. The scheme has the advantage of simple implementation with a DSP; only a smaller memory is needed. The simulation result shows that our scheme keeps the advantage of the traditional one with a higher speed andno particular requiments for image size.

Key words: image watermarking, second-generation wavelet transform, wavelet lifting, multiresolution
