Abstract: Biometric characteristics such as face,fingerprint,iris and signature,etc.are applied successfully for personal verification and identification.A cryptographic key generator based on biometric characteristics is proposed,which is convenient,cheap and secure.The similarities between characteristics are eliminated by some signal processing methods.Experiments on Windows mobile phone demonstrate the effectiveness and security of the proposed algorithm.

Key words: biometric characteristics, random number, mobile phone, wavelet

摘要: 人的生物特征如手写签名、指纹、虹膜等已被成功应用于各种身份认证和识别系统中。提出了一种基于生物特征的密钥产生器,具有安全、成本低和使用方便等的优点。算法采用信号处理方法来消除生物特征中的相似性,并在Windows智能手机上进行了验证,实验证明了算法的有效性和安全性。
