Abstract : In this paper , We propose a new method for image watermarking technique based on chaotic fourier transform. Image watermarking technique has become an interesting field of research for the protection of copy right of data. Logistic or chaotic maps have been used in the proposed technique. Chaotic maps are used to generate the random phase masks and this phase masks are known as chaotic random phase masks. Chaotic maps have been used in watermarked encoding and decoding process.The watermark encoding method in the proposed technique is based on the double random phase encoding method. Chaotic maps used to generate the CRPM. Numerical simulations have been performed on a matlab platform to verify the validity of the proposed technique. In simulation’s results, we have discussed input image , host image , the first CRPM, the second CRPM.

Keywords : Image watermarked encoding and decoding , Chaotic maps/Logistic maps ,CRPM (Chaotic random phase mask) , Chaotic Fourier transform
