Abstract:     A method and apparatus for watermarking an information signal to generate multiple different watermarked copies of the information signal is disclosed. The information signal is segmented into information segments. The plurality of differently watermarked versions of each information segment is then generated and one of the watermarked versions for each segment is selected for each one of the multiple different copies to be generated to generate a sequence of differently watermarked segments which is different for each copy.
