Abstract:
In the face of geometrical attacks,all shortcomings of the almost all digital watermarking algorithms have been exposed.Perhaps there is no algorithm against every attack especially geometrical attacks.It is designed a novel blind image watermarking algorithm of Scalar Costa System based on the DWT transformation in the Rotation-and Scale-and Translation-(RST) Moment Invariant Wavelet,i.e.RSTMIW domain.The experiments show that this novel algorithm is robust against RST geometrical,filter and noise attacks,however,sensitive to some local geometrical attacks.
