Abstract :
In this paper, we present a robust and secure blind digital image watermarking algorithm. The algorithm is based on changing the intermediate significant bit (ISB) of the low-frequency approximation subband (LL) of the DWT domain to embed watermark into host image. Experimental results demonstrate the robustness against several common image-processing operations.
