In this paper, a new invisible digital watermarking technique that uses discrete wavelet transform (DWT), intermediate significant bit (ISB) and transparent watermark background is introduced. The technique combines 2D-DWT and the transparent watermark background to prevent the effect of the corresponding pixels of the cover image and to reduce the impact of watermark embedding on its quality. The experimental results show a significant enhancement of quality of watermarked image on the expense of the extracted message quality and robustness of the proposed technique on a range of attack types.
