一种基于自然数的LSB数据隐藏技术

An LSB Data Hiding Technique Using Natural Numbers

Sandipan Dey, Ajith Abraham, Sugata Sanyal

摘要:

本文提出了一种新的数据隐藏技术,作为Battisti等人提出的Fibonacci LSB数据隐藏技术的改进,基于自然数之和的数字(像素值)的分解。该特定表示再次生成适合于嵌入目的的不同的(虚拟)位平面集合。与Prime技术相比,我们得到了更多的位平面,这些位平面不仅允许在更高的位平面上嵌入秘密信息,而且在没有太大失真的情况下嵌入秘密信息,具有更好的隐写图像质量,并且以可靠和安全的方式保证了秘密信息的有效提取。通过对经典的最低有效位(LSB)方法、Fibonacci LSB数据隐藏技术和本文提出的方案的性能比较研究表明,与素数和Fibonacci分解技术相比,采用自然分解方法隐藏的隐写图像质量有了显著提高。实验结果还表明,隐写图像与原始封面图像在视觉上是不可区分的。我们还展示了我们的技术的最优性。

英文摘要:

In this paper, a novel data hiding technique is proposed, as an improvement over the Fibonacci LSB data-hiding technique proposed by Battisti et al,based on decomposition of a number (pixel-value) in sum of natural numbers. This particular representation again generates a different set of (virtual) bit-planes altogether, suitable for embedding purposes. We get more bit-planes than that we get using Prime technique.These bit-planes not only allow one to embed secret message in higher bit-planes but also do it without much distortion, with a much better stego-image quality, and in a reliable and secured manner, guaranteeing efficient retrieval of secret message. A comparative performance study between the classical Least Significant Bit(LSB) method, the Fibonacci LSB data-hiding technique and the proposed schemes indicate that image quality of the stego-image hidden by the technique using the natural decomposition method improves drastically against that using Prime and Fibonacci decomposition technique. Experimental results also illustrate that, the stego-image is visually indistinguishable from the original cover-image. Also we show the optimality of our technique.
