This paper introduces a steganography technique using the concept of virtual bit-plane. Purposely another number system has been used in this technique instead of binary to hide the target data. After that embedding of target data is done on different bit-planes. Here for conversion, Lucas Number system is used. The Lucas sequence is almost similar to Fibonacci, instead 1 and 2 it starts with 2 and 1. It helps to increase robustness by embedding data at the second bit-plane with a slight change of ±1. Here for embedding target data, Blue and Green channels of RGB color image are used. Red channel is used as indicator for proper extraction of target data at the receiver side. The indicator is used to avoid lexicographically higher order to consider for number representation. It may seem that the use of two channels for embedding reduces the capacity. But it does not really happen. The skip of pixel to follow Zekendrof’s rule for handling redundant representation by other existing methods, make the proposed one more capacitive than other. In order to establish its efficiency over the state-of-art-works the proposed method is analyzed by using different parameters and compared with relevant techniques. It has been found from the tested result that the proposed one is better. The stego quality of the method is also maintained along with the robustness and capacity. The PSNR of the proposed method is within the acceptable range, even in the highest embedding capacity.

本文介绍了一种利用虚拟位平面概念的隐写技术。故意在此技术中使用了另一个数字系统，而不是使用二进制来隐藏目标数据。之后，将目标数据嵌入到不同的位平面上。为了进行转换，使用了卢卡斯编号系统。Lucas序列几乎与Fibonacci相似，取而代之的1和2以2和1开头。它通过将数据嵌入第二个位平面并稍有±1的变化来帮助提高鲁棒性。在这里，为了嵌入目标数据，使用了RGB彩色图像的蓝色和绿色通道。红色通道用作指示符，用于在接收器端正确提取目标数据。该指示符用于避免按字典顺序的更高顺序考虑数字表示形式。似乎使用两个通道进行嵌入会降低容量。但这并没有真正发生。像素的跳跃遵循Zekendrof规则以通过其他现有方法来处理冗余表示，使得所提出的像素比其他方法更具容性。为了确定其在最新技术中的效率，通过使用不同的参数对提出的方法进行了分析，并与相关技术进行了比较。从测试结果发现，提出的一种更好。该方法的隐秘质量以及鲁棒性和容量也得以保持。所提出的方法的PSNR即使在最高嵌入容量下也处于可接受的范围内。使建议的电容比其他电容更大。为了确定其在最新技术中的效率，通过使用不同的参数对提出的方法进行了分析，并与相关技术进行了比较。从测试结果发现，提出的一种更好。该方法的隐秘质量以及鲁棒性和容量也得以保持。所提出的方法的PSNR即使在最高嵌入容量下也处于可接受的范围内。使建议的电容比其他电容更大。为了确定其在最新技术中的效率，通过使用不同的参数对提出的方法进行了分析，并与相关技术进行了比较。从测试结果发现，提出的一种更好。该方法的隐秘质量以及鲁棒性和容量也得以保持。所提出的方法的PSNR即使在最高嵌入容量下也处于可接受的范围内。
