一种基于随机化的彩色图像安全循环隐写技术
A Secure Cyclic Steganographic Technique for Color Images using Randomization
摘要：
信息安全是当今时代的一个主要问题。几乎所有的通信机构都希望其个人数据的安全性、机密性和完整性。但是，当我们使用一个开放的网络，如互联网，这一安全目标并不容易实现。隐写术为这个问题提供了最好的解决方案之一。本文提出了一种新的基于最低有效位（LSB）的真彩色（RGB）图像循环隐写技术（CST）。该方法以随机循环的方式将秘密数据隐藏在覆盖图像像素的LSB中。所提出的技术进行评估，使用主观和客观的分析，直方图的可变性，峰值信噪比（PSNR）和均方误差（MSE）。实验结果表明，该方法在安全性、不可见性和鲁棒性方面都优于已有的方法，证明了该方法的有效性。
英文摘要：
Information Security is a major concern in today's modern era. Almost all the communicating bodies want the security, confidentiality and integrity of their personal data. But this security goal cannot be achieved easily when we are using an open network like Internet. Steganography provides one of the best solutions to this problem. This paper represents a new Cyclic Steganographic T echnique (CST) based on Least Significant Bit (LSB) for true color (RGB) images. The proposed method hides the secret data in the LSBs of cover image pixels in a randomized cyclic manner. The proposed technique is evaluated using both subjective and objective analysis using histograms changeability, Peak Signal-to-Noise Ratio (PSNR) and Mean Square Error (MSE). Experimentally it is found that the proposed method gives promising results in terms of security, imperceptibility and robustness as compared to some existent methods and vindicates this new algorithm.
