Abstract
A watermarking key consisting of a sequence of elements is embedded into a data sequence. Each element may take on two or more values. In order to embed a watermarking key, first a reference sequence is divided into blocks. Each element of the watermarking key is associated with a respective block of the reference sequence. A watermarked sequence is then generated by shifting the associated blocks by a degree determined by the value of the respective associated element of the watermarking key.
