无损恢复是可视秘密共享的重要内容。本文提出了一种新的基于基本矩阵的VSS无损恢复算法。该算法具有利用简单的加法运算就能无损重建秘密图像的优点。该算法通过分析基本矩阵各列相加的汉明重量，证明了秘密图像无损恢复的条件为：1. 0 0. 1 = 1. 0。仿真结果验证了该方案的有效性。
Lossless recovery is very important for visual secret share (VSS). In this paper, a novel lossless recovery algorithm for the basic matrix-based VSS is proposed. The algorithm has the merit of reconstructing secret image losslessly by using simple addition operation. The algorithm proves that the condition of lossless recovery of the secret image isξ0 ∩ξ1 =∅by analyzing the Hamming weight of adding all columns of basic matrixes. Simulations are conducted to evaluate the efficiency of the proposed scheme.
