- W2377778835 abstract "This paper proposes a new algorithm of digital audio watermarking based on the discrete cosine transform.The audio signal has been divided into several frames which include the same samples,and the frame has been divided into several sections which include the same samples.The first section and second section of the specified frame has been transformed by discrete cosine,the sum of the absolute value of the middle and high frequency DCT coefficient has been compared,according to the result of comparison and combining watermark bit,adopting the way of not changing,increasing or reducing coefficient of the DCT,watermarks has been embedded into the DCT coefficients.The result demonstrates that the algorithm is robust,transparent and blind against common signal processing manipulations and attacks,such as re-sample,remodulation,noise,low-pass filter and conversion etc." @default.
