Selection of a suitable watermarking technique is not easy since there exist many kinds of watermarking techniques for variant types of watermarks. In this paper, a novel adjusted-purpose digital watermarking technique is presented to simplify the selection and to integrate different watermarking techniques. The quantity factor is used to affect the embedded watermarks to become fragile, semi-fragile or robust watermarks. The varying sized transform window is designed to determine whether the embedded strategy should be in spatial or frequency domains. Furthermore, by extracting pixel-based features, our watermarking technique cannot only improve robustness of embedded watermarks, but also provide an integrated view in studies of digital watermarking.
