提出了人脸特征的密钥生成算法,该算法采用了FCS算法思想,利用纠错编码技术和hash算法将用户随机密钥用生物特征信息隐藏,实现了安全的密钥恢复和身份认证双重功能,不仅有效地保护了用户密钥而且防止了用户生物特征信息泄露。实验表明,该算法对生物密钥的生成和安全管理是一种行之有效的方法。
This paper proposed a scheme of key generation from face features. This scheme was based on FCS ( fuzzy commitment scheme) and utilized the error-correct encoding technique and hash algorithm to hide random key into biometric features. It realized secure key recovery and authentication. This scheme not only protects the user' s key but also prevents user' s biometric features revealed effectively. The design is provably effective for biometric key generation and secure management through the experiment.
