A fast and secure MP3 steganographic scheme with multi-domain

The problem of single domain embedding and encoder dependence exists in almost all adaptive MP3 steganographic schemes, leading to relatively concentrated modification, limited embedding capacity, long execution time, and re-compression. Therefore, a fast and secure MP3 steganographic scheme with multi domain is proposed in this paper. First, to enlarge the embedding capacity and spread the modifications, we extract the linbits and sign bits of quantized modified discrete cosine transform (QMDCT) coefficients to combine multi-domain. Second, a distortion function is designed based on the statistical properties of the inter and intra frames for better security. The message is embedded into the multi-domains by incorporating the syndrome trellis coding (STC) with the distortion function. Finally, the embedding method is able to get rid of the MP3 encoder and further avoid the problems of re-compression. Experiments illustrate that our scheme achieves a significant improvement in imperceptibility and statistical undetectability. In addition, the execution time is decreased by 63.6% similar to 76.7%, and the embedding capacity is increased by at least 47.4%. (c) 2021 Elsevier B.V. All rights reserved.

Automated summary

A fast and secure MP3 steganographic scheme with multi-domain is proposed in this paper to address the issues of single domain embedding and encoder dependence. By combining multiple domains and designing a distortion function based on statistical properties, the scheme significantly improves imperceptibility and statistical undetectability, while decreasing execution time and increasing embedding capacity.
