| 摘 要： | 指出了现有指纹Fuzzy Vault方法用于加密长度较短的密钥时安全性不足的问题,并基于Fuzzy Vault方案,提出了一种指纹细节特征加密方法.首先指定Fuzzy Vault编码多项式的幂次,并根据指定幂次对加密密钥进行处理和隐藏.通过这种处理,避开了现有方法中密钥长度决定Fuzzy Vault编码多项式幂次的弊端,解除了现有方法加密长度较短的密钥时所存在的安全隐患.

| Abstract: | The existing fingerprint fuzzy vault schemes are not secure when they are used to encrypt a short secret,a novel fingerprint feature encryption method is proposed based on fuzzy vault scheme.First,the degree of encoded polynomial of fuzzy vault scheme based on the decryption requirement is sepecified,and the secret based on the specified degree sequentially is hided.In this way,the proposed method avoided the drawback that the degree of encoded polynomial of fuzzy vault is determined by the length of secret... |
