摘要:

提出了一种基于混沌分形映射的DCT域隐写方法。该方法利用一个128位的私钥和一个混沌分数映射将秘密信息嵌入到图像的某些高频系数中,从而产生一个表示秘密信息嵌入位置的置换。实验结果表明,该方法在隐写系统的不可见性、质量、相似性和安全性分析等方面具有良好的性能。通过峰值信噪比(PSNR)和相对熵(RE)分析,该算法提高了隐写系统的不可见性和Cachin安全性。

英文摘要:

A steganographic method based on the chaotic fractional map and in the DCT domain is proposed. This method embeds a secret message in some high frequency coefficients of the image using a 128-bit private key and a chaotic fractional map which generate a permutation indicating the positions where the secret bits will be embedded. An experimental work on the validation of the proposed method is also presented, showing performance in imperceptibility, quality, similarity and security analysis of the steganographic system. The proposed algorithm improved the level of imperceptibility and Cachin's security of stego-system analyzed through the values of Peak Signal-to-Noise Ratio (PSNR) and the Relative Entropy (RE).
