This paper proposes a digital watermarking scheme based on fractal image coding with DCT coefficient and needs no information about the original image. In previous work, we have proposed the digital watermarking scheme based on fractal image coding with a DCT coefficient between the range block and

A cyclic arithmetic code is a subgroup of \(\mathbf{Z} /\left(r^{n}-1\right) \mathbf{Z}\), where the weight of a word \(x\) is the minimal number of nonzero coefficients in the representation \(x \equiv \sum_{i=0}^{n-1} c_{i} r^{i}\) with \(\left|c_{i}\right|<r\) for all \(i\). A code is called equi
