Content protection for multimedia data is widely recognized especially for data types that are frequently distributed, sold or shared using the Internet. Particularly music industry dealing with audio files realized the necessity for content protection. Distribution of music sheets will face the same problems.
Digital watermarking techniques provide a certain level of protection for these music sheets. But classical rasteroriented watermarking algorithms for images suffer several drawbacks when directly applied to imiage representations of music sheets. Therefore new solutions have been developed which are designed regarding the content od the music sheets. In Comparison to other media types the development for watermarking of music scores is a rather young art. The paper reviews the evolution of the early approaches and describes the current state of the art in the field.
