The algorithm proposed uses the transformed into wavelet Legall 5/3 on an image encrypted by swapping on the Z/pZ field, to perform the watermarking. By consequence, this introduces the concept of keys to the traditional methods of non-blind watermarking. The results of the application of this method on the fixed image (presented in the section: Application and results show well its performance.}, journal = {Journal of Computer Science}, publisher = {Science Publications} }
