A DWT-based Digital Watermarking Scheme for Image Tamper Detection, Localization, and RestorationA discrete wavelet transform (DWT)-based watermarking scheme for this purpose is proposed in this communication. In our scheme, the original image is first partitioned into blocks of size 2?×?2 in which a 1D DWT is applied to produce a watermark which is embedded in four disjoint partitions of the i
