基于视觉密码的虹膜身份认证

Secure Iris Authentication Using Visual Cryptography

P. S. Revenkar, Anisa Anjum, W. Z. Gandhare

摘要:

生物识别技术处理基于生理或行为特征识别人或验证人的身份的自动化方法。视觉密码是一种秘密共享方案,其中秘密图像被加密成独立的份额,不泄露关于原始秘密图像的信息。由于生物特征模板存储在集中式数据库中,由于安全威胁,生物特征模板可能被攻击者修改。如果生物特征模板被更改,授权用户将不被允许访问资源。为了解决这个问题,可以应用视觉密码方案来保护虹膜模板。视觉密码学提供了很好的方法来满足这种安全需求,以及额外的身份验证层。

英文摘要:

Biometrics deal with automated methods of identifying a person or verifying the identity of a person based on physiological or behavioral characteristics. Visual cryptography is a secret sharing scheme where a secret image is encrypted into the shares which independently disclose no information about the original secret image. As biometric template are stored in the centralized database, due to security threats biometric template may be modified by attacker. If biometric template is altered authorized user will not be allowed to access the resource. To deal this issue visual cryptography schemes can be applied to secure the iris template. Visual cryptography provides great means for helping such security needs as well as extra layer of authentication.
