摘要：With spreading of digital contents, stealing other's properties by unpermitted people have become easier. In order to protect thelegitimate rights of owners, the digital watermark technologies are becoming more popular. In this paper, we propose an audio watermarking algorithm based on DCT coefficients and audio feature quantization. The proposed algorithm protects watermark informationusing several factors, such as filtering, audio feature extraction formula, quantization value, etc. Furthermore, in order toevaluate the performance of our proposed algorithm, we experiment our algorithm under the attacks such aslow pass filtering, noise addition, and compression. From the experiment result, we can see thatthe proposed algorithm has high robustness
