An Invariable to Rotation Data Hiding Scheme for Semi-Fragile Blind Watermark

An invariant to rotation watermarking approach is proposed for the purpose of improving the security of digital images. The proposed digital watermark approach is invariable to rotation and guarantees the integrity of the inserted mark. The size of the resulting image is identical to the original image and the process guarantees acceptable transparency. This approach evolves both in the frequency and the spatial domain. Specifically, the...
