摘　　要：本文给出了一种分享为有意义图像的视觉密码方案,利用参与者和其他参与者的分享图像叠加能否恢复出验证图像来实现参与者真实性检验,分享图像不易引起攻击者的怀疑,并且还检验了其他参与者的真实性。该方案中分享图像都有意义且任意2个分享图像的叠加结果为验证图像,用来验证参与者身份真实性,不能泄露秘密图像的任何信息。实验证实了所给方案的有效性。This paper proposes a visual cryptography scheme for sharing meaningful images. The scheme verifies the participants′ authenticity by superimposing the share of participants and the share of other participants together to restore the verified images. After that, the sharing images are not easy to arouse the suspicion of the attacker and in this way the authenticity of participants can also be checked. In this scheme, the sharing images are meaningful and the result of superimposing any two shared images is the verification image, which is used to verify the authenticity of the participants, and can not reveal any information of the secret image. The experiment has proved the effectiveness of the scheme.
