Abstract
This paper proposes a robust blind watermarking scheme for digital images based on discrete fractional random transform, a generalization of the discrete fractional Fourier transform with intrinsic randomness. The proposed watermarking scheme can be easily used to embed and extract a watermark and it provides strong information security because of its inherent randomness. Experimental results obtained by subjecting the watermark to several types of attacks reveal that it is robust against frequency and geometric attacks, thus verifying its effectiveness.
