| Abstract: | A novel multiple audio watermarking algorithm based on vector quantization technique and DCT transformation is proposed.To accomplish the purpose of copyright protection and content integrity authentication at the same time,the robust and fragile watermarks are both embedded into the carrier audio signal.The robust watermark is embedded into the middle frequency coefficients of DCT during the codeword labeled vector quantization process,and the fragile watermark is embedded into the high frequency DCT coeff... |
