A REVERSIBLE MULTIPLE WATERMARKING SCHEME BASED ON LIFTING WAVELET TRANSFORM

The multiple watermarks are fused in to a single watermark using a fusing technique for high security. In reversible watermarking the watermark and the original image can be extracted without any distortion. In proposed algorithm the watermarks are embedded into fifth bit-plane of the integer lifting wavelet transform coefficients in the detailed sub bands. Bit plane embedding using arithmetic coding technique and lifting wavelet transform to improve the quality of watermarked image. Experimental results show that the performance of proposed algorithm achieves embedding capacity, high security, good image quality of different wavelet families and completely reversible.
