摘要
提出一种安全、可靠的(k,n)门限图像秘密共享方案。在该方案中影子图像的大小小于原秘密图像,图像恢复具有无质量损失的特性。由于新方案将秘密图像分割成一些块图像,因此对图像可以进行实时处理。该方案在对图像保密有较高要求的场合有一定的实用价值。
A secure and reliable (k, n) image secret sharing scheme is proposed. This scheme's advantages are its large compression rate on the size of the image shares and it has no mass property in image reconstruction phase. Because the original secret image is divided into some block images in the new scheme, it has the ability of the real-time processing. This scheme is useful in the high requirement of the image security.
