Securing fuzzy vault schemes through biometric hashing
Fuzzy vault biometrics biometric hashing fingerprint privacy
2010/10/12
The fuzzy vault scheme is a well-known technique to mitigate privacy, security, and usability related problems in biometric identification applications. The basic idea is to hide biometric data along ...
基于指纹的可撤销Fuzzy vault方案
Fuzzy vault 可撤销模板 指纹细节点
2009/9/18
Fuzzy vault是一种用生物特征保护密钥的加密框架，其主要缺点在于攻击者可以通过交叉比较同一用户的不同vault来获得生物模板的准确信息，从而可以破解vault。提出了一种使用基于指纹细节点的可撤销的变换模板作为生成vault的模板，保护不同密钥时采用不同变换模板，从而解决了这个问题。采用以巴特沃斯低通滤波器为核的函数组作为生成可撤销模板的变换函数。此外还使用了用户口令加密vault，从而进...

GRS解码在Fuzzy Vault中应用
Fuzzy Vault 表单解码 生物加密
2009/7/24
将指纹细节点和密钥进行绑定，并用fuzzy vault方法对结果进行保护。在密钥恢复时，用GRS解码进行纠错处理。对GRS的传统解码和表单解码的效果进行了比较，实验表明表单解码比传统解码的密钥恢复效果更好。
