In this paper we propose a watermarking system that

uses the biorthogonal discrete wavelet transform, DWT and the

message is encoded before embedding. The proposed

watermarking method is very simple, implying four steps: turbo

coding of the watermark message, embedding the turbo coded

watermark into the host image using a perceptual mask,

extraction of the turbo coded watermark from the watermarked,

possibly corrupted image, and turbo decoding of the watermark.

The goal of this paper is the association of the DWT and duobinary turbo codes. Some simulation examples prove the

performance of the proposed watermarking method- In this paper we propose a watermarking system that
