论文摘要
JPEG图像的广泛使用使它们可以很好地封面存储和传输秘密消息。本文提出了一种新算法,用于基于隐志QIM方法中的JPEG图像中嵌入信息。这种嵌入的主要问题是易受统计切解分析的脆弱性。为了解决此问题,建议使用一个可变量化步骤,该步骤可适应为JPEG封面图像的每个块选择。实验结果表明,所提出的方法成功地提高了嵌入的安全性。
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.
