利用QIM方法在压缩JPEG图像中嵌入信息的自适应算法

An adaptive algorithm for embedding information into compressed JPEG images using the QIM method

Anna Melman, Pavel Petrov, Alexander Shelupanov

摘要:

JPEG图像的广泛应用为秘密信息的存储和传输提供了良好的掩护。提出了一种基于隐写QIM方法的JPEG图像信息嵌入新算法。这种嵌入的主要问题是统计隐写分析的脆弱性。为了解决这个问题,提出了使用可变量化步长,这是自适应选择的JPEG封面图像的每个块。实验结果表明,该方法成功地提高了嵌入的安全性。

英文摘要:

The widespread use of JPEG images makes them good covers for secret messages storing and transmitting. This paper proposes a new algorithm for embedding information in JPEG images based on the steganographic QIM method. The main problem of such embedding is the vulnerability to statistical steganalysis. To solve this problem, it is proposed to use a variable quantization step, which is adaptively selected for each block of the JPEG cover image. Experimental results show that the proposed approach successfully increases the security of embedding.
