摘要
针对现在大多图像信息隐藏算法中存在的隐藏容量小、安全性差的问题,提出了一种基于特定数学原理的载体图像分存隐写算法。首先构建图像分存的隐写模型,其次阐述了Bernstein多项式和Frobenius数问题的性质以及相关定理并提出分存算法,然后将载体图像进行分存变换,最后,给出了隐秘信息的嵌入与提取算法,并进行了分存隐写和抗攻击实验。实验结果和分析表明本算法增大了隐写容量,降低了载体图像的感知质量、提高了隐秘信息的安全性。
For now most of the image information hiding schemes have the problem of small steganography capacity and poor security,so,proposing a cover image sharing steganographic algorithm based on the mathematical theory.Firstly,constructed image sharing steganographic model,then described the properties and related theorems of Bernstein polynomial and the Frobenius number of issues,also proposed sharing principle and shared the cover images.Finally,algorithms of embedding and extraction were given;experiments of coverr images sharing steganography and anti-attack were completed.The result and analysis of experiments show that algorithm increases embedding capacity,reduce the perceived quality of cover image and improves security of secret information.
