Abstract

Different steganography techniques have been presented based on RGB image as the image is considered secure cover for hidden data. Specifically, this paper presents edge-based image steganographic method using parameterised Canny edge detector that relies on embedding the secret message bits into variable LSB length of the blue colour channel of the cover image. The blue colour channel is selected because the steganography-based research showed that the visual perception of blue colour intensity is less distinct than the red and green colours. Secret message bits are embedded up to four bits of LSB which are selected by a random number generator. Additionally, as the less significant information is carried out by the LSB of each pixel so slight changes of LSB will not affect the visual quality of the cover image. The proposed algorithm was tested on a set of RGB colour images, and satisfactory results were demonstrated regarding minimum distortion in the blue colour of a pixel and visually identical original and stego image.
基于改进LSB替换的安全RGB图像隐写
由于RGB图像被认为是隐藏数据的安全保护层,各种基于RGB图像的隐写技术已经被提出。具体来说,本文提出了一种基于边缘的图像隐写方法,该方法使用参数化Canny边缘检测器,将秘密信息位嵌入到封面图像蓝色通道的可变LSB长度中。选择蓝色通道是因为基于隐写术的研究表明,蓝色的视觉感知强度不如红色和绿色明显。秘密消息位最多嵌入4位LSB,这些LSB由随机数生成器选择。此外,由于不太重要的信息是由每个像素的LSB进行的,所以LSB的微小变化不会影响封面图像的视觉质量。在一组RGB彩色图像上对该算法进行了测试,在一个像素的蓝色最小失真和视觉上相同的原始图像和隐写图像上证明了令人满意的结果。
