Abstract :
This paper proposes a blind audio watermarking scheme for marking multiple copyright owners. The problem of interference between each watermark is solved by scrambling technology. Experimental results show good transparency and robustness of the scheme. The watermarking extraction procedure depends on the private key of specific copyright owner, which guarantees the security of the multi-watermarking scheme.
