摘　　要：针对基于数字图像信息隐藏技术的抗旋转性和抗剪切性的要求,提出一种基于空间域lαβ环形冗余解析的信息隐藏算法。将数字图像按照lαβ颜色空间模式进行分解,选择能量较小的α,β分量作为载体图像进行圆环等量分割,并通过修改圆环区域的像素均值达到嵌入信息的目的。该算法采用在以圆心对称的环形区域内嵌入相同秘密信息的方法,可有效抵御旋转性攻击和抗剪切性;通过改变圆环数和区域面积以增减嵌入的信息量,且不可见性不随嵌入容量的增减而改变;信息隐藏分析检出率小于4.35%。实验表明该算法具有良好的抗旋转性、抗剪切性以及抗分析性能。To satisfy the requirements of the anti-rotation and anti-cutting performance of the information hiding technologybased on digital image, an information hiding algorithm based on spatial domain left annulus redundancy analysis is proposed.The digital image is decomposed according to the laβ color space mode, and then a and β components with small energy areselected as the carrier images for equal segmentation of the annulus. The modification of the pixel mean value in the annulus canrealize the purpose of information embedding. The method of embedding the same secret information in the annulus area with thecircle center symmetry is adopted in the algorithm to resist the rotation attack and anti-cutting performance effectively. Thechange of annulus quantity and region area can regulate the embedded information content, and the invisibility doesn＇t changewith the embedded capacity. The detection rate of the information hiding analysis is less than 4.35%. The experimental resultsshow the algorithm has good anti-rotation, anti-cutting performance and anti-analysis performance.
