摘　　要：针对分享份为无意义的随机二值图像问题,提出了一种分享为有意义的且具有核心参与者的视觉密码共享(2,4,3,6)方案。其中,参与恢复秘密图像的分享份中必须包含指定数量的核心分享份。与传统的具有核心参与者的视觉密码方案不同,该方案生成的分享图像不再是杂乱无章的噪声图像,而是包含特定的图像信息。方案主要利用构造基础矩阵的思想实现具有核心参与者的视觉密码共享(2,4,3,6)方案的构造。该方案对于提高视觉密码的安全性和可用性具有重要的意义,可以很好地满足实际应用的需要。实验结果验证了所提出方案的有效性。A visual cryptography sharing(2,4,3,6)scheme with meaningful shares and having essential participants is proposed for the problem of sharing random binary images.The shares involved in restoring secret images must include a specified number of essential shares.Different from traditional visual cryptography schemes with essential participants,the shared images generated by this scheme are no longer chaotic and noisy images,but contain specific image information.The scheme mainly realizes the construction of a visual cryptography sharing(2,4,3,6)scheme with essential participants by using the idea of constructing foundation matrix.The scheme is of great significance to improve the security and usability of visual cryptography.It can also meet the needs of practical applications.The experimental result verifies the effectiveness of the proposed scheme.
