Abstract: A blind watermarking algorithm for embedding MIDI (Musical Instrument Digital Interface) information into a binary image of music score based on the optical music recognition (OMR) is presented. Both the information of digital music score and MIDI can be reconstructed. Experiment results show that the embedded watermark has no effect on the precision of music score recognition. It is useful in integrity auditing and synchronized transmission of digital music score together with the MIDI information.

Key words: blind watermarking algorithm, digital music score, musical instrument digital
