随着大规模适应基于生物识别的应用程序，生物识别技术的安全性和隐私性变得至关重要，尤其是在无人监督的在线模式下运行时。这项工作提出了一种新的方法来生成新的人工指纹，也称为代理指纹，它看起来自然、不可逆、可撤销且保护隐私。这些代理生物识别信息只能在用户特定密钥的帮助下从原始生物识别信息生成。这些代理模板可以在任何地方以同样的便利性使用，而不是使用原始指纹。这些手稿介绍了一种有趣的方式，可以生成不同类型的代理指纹，以及如何将它们与特定于使用的密钥结合起来，以在发生妥协时提供可撤销性和可取消性。使用所提出的方法，从属于 Anguli 指纹数据库的样本生成代理数据集。在比原来大5倍的新集合上进行匹配实验，发现它们在被盗密钥、安全密钥场景下的性能与0 FAR和0 FRR相当。还分析了有关可撤销性和多样性的其他参数的保护性能。
With large-scale adaption to biometric based applications, security and privacy of biometrics is utmost important especially when operating in unsupervised online mode. This work proposes a novel approach for generating new artificial fingerprints also called proxy fingerprints that are natural looking, non-invertible, revocable and privacy preserving. These proxy biometrics can be generated from original ones only with the help of a user-specific key. Instead of using the original fingerprint, these proxy templates can be used anywhere with same convenience. The manuscripts walks through an interesting way in which proxy fingerprints of different types can be generated and how they can be combined with use-specific keys to provide revocability and cancelability in case of compromise. Using the proposed approach a proxy dataset is generated from samples belonging to Anguli fingerprint database. Matching experiments were performed on the new set which is 5 times larger than the original, and it was found that their performance is at par with 0 FAR and 0 FRR in the stolen key, safe key scenarios. Other parameters on revocability and diversity are also analyzed for protection performance.
