Watermark is an invisible signature embedded inside an image to show authenticity or proof of ownership. The watermark pattern owner wants to keep their watermark patterns private during the watermark detection. In this paper, Lifting Wavelet Transform (LWT) technique is used for secure watermark detection. The Lifting Wavelet Transform (LWT) technique embeds ownership information into the host contents without degrading the perceptual quality of the host contents. Mainly this algorithm progresses the peak to signal noise ratio than the existing Discrete Cosine Transform (DCT) technique.
