Abstract
The topic of intellectual property right protection has been noticed. Nowadays, due to the rapid development of computer multimedia technology, people can easily produced, process and retrieve audio media by using digital devices. Therefore, it induced two problems, the security of digital message transfer and the intellectual property right protection of the work in digital form. This essay proposed a method of embedding a watermark, hidden message about the copyright. Whenever a quarrel about the owner of copyright occurs, we can extract the watermark and prove the ownership. This method adopts acoustic models and genetic algorithms to determine the proper scaling of watermark energy such that the quality of the original signal and robustness of the watermark are still preserved.
