摘要

视觉密码学是一种秘密共享技术，用于隐藏图像上的秘密数据。它使用人类视觉系统进行解密。在彩色扩展视觉密码术(Color EVS)中，机密数据在有意义的彩色图像中共享。采用误差扩散技术进行数字半调。利用附加基矩阵(ABM)和白像素完美重构(PRWP)技术提高了解密图像的质量。

Quality improvement in Color Extended Visual Cryptography using ABM and PRWP

Visual Cryptography is a secret sharing techniquue to hide secret data on images. It uses human visual system for decryption. In Color Extended Visual Cryptography (Color EVS) secret data is shared in meaningful color images. Error diffusion technique is used for digital halftoning. Use of Additional Basis Matrix (ABM) and Perfect Reconstruction of White Pixel (PRWP) technique improve the quality of decrypted image.
