Watermarking music sheets while printing

Watermarking allows hiding of information in digital objects such as images, videos, audio files and text pages. These techniques are adopted to hide codes that can be used to demonstrate the digital object´s ownership in case of verification of copyright infringement. A novel technique for watermarking music in the phase of music sheet printing is presented. The solution was obtained by taking into account the skills of musicians in detecting changes in the music sheets. A validation of the results obtained has been performed by using technical verification of robustness and a group of experts.
