Abstract :
A blind audio watermarking algorithm based on convolutional code is proposed in this paper. Watermark information is embedded in the low-middle frequency coefficients in lifting wavelet domain adaptively. In order to improve the ability to resist the disturbance, the watermark is processed by convolutional encoding and interleaving before embedding. Watermarking detection algorithm using Viterbi soft-decision decoding is presented. The experimental results show that the performance of the proposed algorithm is good
