论文摘要
我们建议借助计算机生成的全息图，以间接的方式实现视觉加密。目前，视觉密码学的恢复方法主要叠加在透明膜上或被计算机设备叠加，这极大地限制了视觉加密的应用范围。在本文中，将视觉加密的份额用计算机生成的全息图编码，并通过光学手段复制股票，然后叠加和解密。此方法可以扩大视觉加密的应用范围，并进一步提高视觉加密的安全性。
We propose to realize visual cryptography in an indirect way with the help of computer-generated hologram. At present, the recovery method of visual cryptography is mainly superimposed on transparent film or superimposed by computer equipment, which greatly limits the application range of visual cryptography. In this paper, the shares of the visual cryptography were encoded with computer-generated hologram, and the shares is reproduced by optical means, and then superimposed and decrypted. This method can expand the application range of visual cryptography and further increase the security of visual cryptography.
