基于心电图和指纹的多生物识别方法

发布时间:2022-01-24 15:49
  传统的身份验证策略(如密码和智能卡)因为它们可以被共享、遗忘、复制、操纵或伪造,其安全性存在隐患。与传统方法不同,生物识别是基于人的生理或行为特征进行身份识别的科学,已成为确定个体身份的合法方法。如今,生物识别技术已不再局限于刑事执法,更多企业使用生物识别技术来管理对建筑物和信息的访问。然而,大多数单模态生物特征识别受到诸如噪声数据,非普遍性和欺骗攻击之类的限制,使得它无法达到现实世界应用的性能要求。为了克服单模态方法的这些缺点,本文提出了一种新颖的安全多模态生物识别方法,使用不同的融合方法将心电图(ECG)与指纹相结合。该方法克服了单一方法的局限性,提高了整体方法的性能并增强了安全性,对欺骗攻击具有更好的鲁棒性。与其他多模态生物识别方法(例如,面部,耳朵和基于指纹的多模态生物识别系统)相比,ECG信号可以容易地从手指获取,这使得系统非常方便和有效。此外,ECG信号只能从活人身体获取,因此还可以据此进行活体检测,使系统具有更强的抗攻击能力。本文的第一部分研究了心电图和指纹作为单模态生物识别的方法。为此,我们首先提出一种改进的生物哈希和矩阵运算方法,为生物识别系统生成了一种新的可取消的心...
