Abstract
An audio watermarking algorithm by modifying the low-frequency coefficients of DWT is discussed in this paper. Audio signal is divided into many sections, whose quantity is equal to the size of the watermark. The maximal value and the second maximal value of DWT low frequency coefficient can be found in each section. Then we can extract the last non-zero number of the two extreme values. The watermark is embedded based on the two numbers’ parity. We take the encryption twice in order to improve security of the watermark. Experiments show that after some common attacks such as resample, Gauss noise, re-quantization and low-pass filtering, the algorithm has good imperceptibility and robustness.
