Abstract

With the advancement of image steganography, coverless image steganography has gained widespread attention due to its ability to hide information without modifying the carrier of images. However, existing coverless image steganography methods often require both communicating parties to transmit an amount of additional information including image blocks’ locations or a large number of parameters, which will raise a serious suspicion. In light of this issue, we propose a robust coverless image steganography algorithm based on Speeded-Up Robust Features (SURF). Firstly, the proposed method allows both communicating parties to independently create multiple coverless image datasets (CIDs) using random seeds. Then, a mapping rule is designed for creating one-to-one correspondence between hash sequences and images in CIDs. Finally, the secret information will be carried by the images whose hash sequences are equal to the secret segments. At the receiver side, the robust SURF of images is utilized to retrieve the secret information. Experimental results demonstrate that the proposed algorithm outperforms other methods in terms of capacity, robustness, and security. Furthermore, it is worth noting that the proposed method eliminates the need to transmit a large amount of additional information, which is a significant security issue in existing coverless image steganography algorithms.
基于 SURF 特征图像检索的鲁棒无掩码图像隐写术算法
随着图像隐写术的发展,无掩盖图像隐写术因其能够在不改变图像载体的情况下隐藏信息而受到广泛关注。然而,现有的无掩码图像隐写方法往往需要通信双方传输大量的附加信息,包括图像块的位置或大量参数,这将引起严重的怀疑。有鉴于此,我们提出了一种基于加速鲁棒特征(SURF)的鲁棒性无掩码图像隐写算法。首先,该方法允许通信双方使用随机种子独立创建多个无掩码图像数据集(CID)。然后,设计一个映射规则,在哈希序列和 CID 中的图像之间建立一一对应关系。最后,哈希序列与秘密片段相等的图像将携带秘密信息。在接收端,利用图像的鲁棒 SURF 来检索秘密信息。实验结果表明,所提出的算法在容量、鲁棒性和安全性方面都优于其他方法。此外,值得注意的是,所提出的方法无需传输大量额外信息,而这正是现有无掩码图像隐写术算法中的一个重要安全问题。
