基于MP3 Huffman编码的多位映射隐藏算法

Multi Bit Mapping Hiding Algorithm Based on MP3 Huffman Coding

摘要: 为解决MP3信息隐藏技术中隐藏容量较小的问题，本文提出一种在Huffman小值区对相同码长的码值多位映射替换编码的算法。该算法再与经典的Huffman大值区隐写算法融合而成基于MP3 Huffman多位映射隐藏算法，实验分析表明该算法具有较高的透明性、嵌入量明显增大、计算量小、音质好，码字的统计特性不明显等特点。

Abstract: In order to solve the problem of hidden capacity in basic MP3 information hiding technology, this paper proposes a code replacement coding algorithm in Huffman small value area for the same code length. This paper proposes an algorithm of code value multi bit mapping substitution coding for the same code length in the Huffman small value area. The algorithm is further integrated with the classical Huffman large area steganography algorithm based on MP3 Huffman multiple mapping. The experimental results show that the algorithm has higher transparency, larger embedded volume, smaller computation and better sound quality. The characteristics are not obvious, and so on.
