Recovering hidden information in audio by genetic algorithm

Abstract

An audio recovering method of spread-spectrum hidden information is proposed based on genetic algorithm. In this method the embedded sequence length is confirmed firstly, then the best estimated sequence with the confirmed length is got by genetic algorithm, finally the confidential message hidden in stego-audio can be recovered. Using this approach, the hidden information can be recovered without any information from the transmitter. The presented method has been implemented on PC, and the experimental results show that the average recovering correct rate is higher than 90%.
