In this paper, we propose a multiple watermarking algorithm which embeds an integrated watermark into content using traditional watermarking algorithm. The integrated watermark consists of multiple watermark information and it is useful to trace illegal distribution. The information is generated by using Dot Code A, which can express multiple user information with error correction. An orthogonal transform and code division multiplexing technology are used to spread Dot Code A. This also ensures the algorithm is robust. The embedding range of the AC coefficients is within [-0.5, -0.3] and [0.3, 0.5] in the discrete cosine transform domain. At an embedding strength of 0.7, the signal-to-noise ratio of the test audio is over 53 dB, and we are able to extract the Dot Code A from the watermarked audio exactly.
