摘要

针对多次采集中指纹特征的差异性和指纹模板的安全性问题,研究了基于Frobenius范数的安全指纹识别系统。Frobenius范数可以显示感兴趣区域(ROI)的主要信息。随机映射结果可以有效地提高对不同用户的区分。与存储在数据库中的原始指纹特征相比,映射结果可以避免对原始指纹特征的攻击。对于给定的指纹数据库,可以得到最优阈值和随机映射矩阵的最优大小。在FVC2002上的实验证明了该识别系统的可行性和有效性。同时,得到了令人满意的EER(等错误率)0.21%。

Secure Fingerprint Recognition Based on Frobenius Norm
Aiming at the variance of fingerprint feature in multi-capturing and the security of fingerprint template, research on secure fingerprint recognition system based on Frobenius norm is given in this paper. Frobenius norm can show the main information in region of interest (ROI). The random mapping results can improve effectively the distinguishment of different users. Compared with the original fingerprint feature being stored in the database, the mapping results can avoid attacking the original fingerprint feature. For the given fingerprint database, the optimal threshold and the optimal size of random mapping matrix can be got. Experiments in FVC2002 show that the proposed recognition system is feasible and effective. Moreover, a satisfactory EER (equal error rate) 0.21% is obtained.
