A novel AAC watermarking scheme with low structural and computational complexity is proposed to achieve real-time AAC audio watermark embedding capability. In this scheme, an enhanced spread spectrum watermarking method that increases the robustness and information hiding capacity of the watermarking channel is developed and employed. Furthermore, this scheme improves the speed of the encoding process in that we directly use the quantized indices rather than the dequantized coefficients, thus… CONTINUE READING
