    Abstract: Watermarking is a data embedding technique widely used to protect rightful
    ownership of digital images. In recent years, several SVD-based watermarking schemes
    have been proposed in the literatures. However, although most existing schemes can provide
    good image quality of the watermarked image and robust embedded watermarks, some
    still need to store extra data or use an original image in order to extract the watermark.
    To overcome these drawbacks, in this paper, we propose a novel SVD-based watermarking
    scheme that contains a recovery mechanism so that the watermarked image can be
    recovered to satisfactory condition after rightful ownership of an image has been established.
    To extend the application of the proposed scheme into commercial applications,
    we also present a variant that inherits the properties of the proposed scheme and provides
    higher image quality in a restored image after the embedded watermark is extracted.
    Experimental results confirm that our primary scheme can withstand a variety of image
    processing techniques and that our variant can successfully reduce the difference between
    a compressed host image and a restored image to less than 2 dB
