一种基于阵列码的图像秘密分享方法

中文摘要: 为了构造图像秘密分享完全的(Perfect)和理想的(Ideal)门限方案(即完备方案)，以及提高分享效率，本文提出了一种基于阵列码的图像秘密分享方法，构造了数字图像(t, n)门限秘密分享的一种完备方案。该方法将图像像素值进行二进制表示，类比于磁盘阵列中的数据信息，采用阵列码方法进行图像像素值阵列的秘密分享。该方法的运算过程只有异或运算，对像素进行并行处理，并且门限结构是完全和理想的。实验结果表明，本文提出的方法效率更高，并且具有更高的安全性。
Abstract:In order to construct a Perfect and Ideal image threshold secret sharing scheme (Complete Scheme) and improve sharing efficiency, a novel secret image sharing complete scheme based on array codes with a (t, n) threshold structure was proposed. The scheme takes image pixel values, in binary form, as the data in disk array, encodes image pixel array using the method of array code. The operation of the scheme is XOR only, and the process is in a parallel way, while the threshold structure is Perfect and Ideal. The results show the proposed scheme is more efficient and has higher security.
