In this letter, we devise an adaptive double-layered embedding scheme that is suitable for MP3 steganography. According to the encoding characteristics of MP3, the linbits are used as the embedding domain. The proposed scheme is divided into two layers and the messages are embedded into each layer with binary STCs. The cost function used in the first layer is designed by employing the masking effect to achieve optimal imperceptibility. In order to reduce the modification of coefficients, the cost function for the second layer is revised according to the embedding results of the first layer. Experiments demonstrate that our scheme is able to achieve better acoustic concealment and higher embedding modifying efficiency indeed. In addition, our scheme can well resist the attack from the statistical handcrafted analysis methods.
