A fragile audio aggregation watermarking algorithm based on Huffman coding

In order to authenticate the integrity of audio aggregation, a fragile watermarking algorithm based on vector quantization has proposed which combining with Huffman coding. Put the output index into Huffman coding after obtaining the index's probability distribution by quantifying index address table. Then use the classical method of cryptography to complete zero-watermark embedding. The experimental results show that the proposed algorithm has good imperceptibility and high security. It has strong vulnerability for audio attacks, and can authenticate the integrity of audio aggregation.
