Digital watermarking has been developed for copyright protection and fighting piracy in the domain of digital media. Due to recent improvements regarding watermarking robustness against printing of images or analogue distribution of audio and video, also the protection of common, non-virtual goods has been enabled. Information can transparently be linked with the goods, providing a protective layer hard to forge or to remove. We discuss recent developments in the area of image watermarking and introduce an algorithm suitable for printing and scanning of packages. Additionally we show typical challenges and solutions for image watermarking caused by typical analogue transformations of marked content.
