Key-privacy is a notion of security that is concerned with the key anonymity in public-key en- cryption. Some popular schemes keep key-privacy, while others do not. Key-privacy has been shown to be orthogonal to data-...

针对传统的基于视觉密码的图像秘密共享方案存在像素扩张导致其只能共享小尺寸的秘密图像、信息隐藏效率较低的问题,提出一种能够提高信息隐藏容量的(t,k,n)多重门限图像秘密共享方案.该方案利用秘密图像信息控制视觉密码方案中共享矩...
