As long as the copyright issue is not solved in a satisfying manner, museums may not offer open access to the digital information of their collection. Watermarks have been used since centuries to prove the genuineness, authenticity, and authorship of documents or certain products of different crafts. In this tradition digital watermarks are used for copyright protection today. They are bits inserted into a digital image, audio, or video file to identify the file's copyright information. They have to be robust against different kinds of manipulations and attacks. Unfortunately, no watermarking tool on the market produces digital watermarks as robust as needed, experts negate its existence at all. Alternate solutions are needed. An infrastructure with or without watermarking the original has to be established. This paper describes related problems and directions to solve them so that a museum can publish parts of its collection with no harm.
