摘要
秘密共享是一种将秘密信息的片段共享给多个合法参与者的保密技术,可以有效预防对秘密信息的破译、截取、恶意破坏。图像秘密共享是近年来一个具有实用价值研究分支,目前已经衍生出很多种共享算法。L.Bai的投影矩阵方案是一种面向图像秘密共享的方案,可对该方案进行改进,对残差矩阵进行保护,可以避免残差矩阵因通信丢失而导致图像无法重构的问题,提高了该方案的安全性和可用性。
Secret sharing is a security technology for sharing fragments of secret information by several legal participants. This method can avoid deciphering, interception or malicious disruption of the secret. Image secret sharing is a branch of practical value. Recently many different algorithms are proposed. L.Bai＇s projection matrix scheme is an image secret sharing-oriented scheme, and it could be modified. The protection implemented on residual matrix could avoid the failure of image reconstruction caused by communication loss, thus the security and availability of this scheme be improved.
