摘要

Petitcolas提出了一种名为MP3Stego的隐写技术，它可以隐藏MP3音频中的秘密信息。这种技术因其高容量而闻名。但是，在极少数情况下，正常的音频编码过程会因为嵌入操作造成的循环问题而终止。此外，还可以进一步提高MP3Stego的统计不可检测性。本文受MP3Stego的启发，提出了一种新的MP3音频隐写方法。采用MP3Stego算法中量化步骤的奇偶校验位而不是块大小的奇偶校验位来嵌入秘密消息。与MP3Stego算法相比，该算法避免了无限循环问题，具有更好的不可感知性和更高的安全性。

Quantization Step Parity-based Steganography for MP3 Audio

Petitcolas has proposed a steganographic technique called MP3Stego which can hide secret messages in a MP3 audio. This technique is well-known because of its high capacity. However, in rare cases, the normal audio encoding process will be terminated due to the endless loop problem caused by embedding operation. In addition, the statistical undetectability of MP3Stego can be further improved. Inspired by MP3Stego, a new steganographic method for MP3 audio is proposed in this paper. The parity bit of quantization step rather than the parity bit of block size in MP3Stego is employed to embed secret messages. Compared with MP3Stego, the proposed method can avoid the endless loop problem and achieve better imperceptibility and higher security.
