Digital Watermark Algorithm for Midi
Midi数字水印算法*

Use software watermark's method into Midi. The method is similar to dynamic graph watermarking.Change the complete binary tree's structure according to the watermark.The confused preorder traversal sequence is the watermarked Midi data. The detection is completely blind. It doesn't need the original music and watermark. The algorithm is imperceptible and is robust to passive attacks and active attacks such as filtering,nosing.
