Abstract

In response to growing demands for secure and user-friendly individual authentication methods, biometric technologies have seen widespread adoption, offering advantages over traditional password- or card-based systems. While current biometric systems primarily rely on physical traits such as fingerprints and facial structures, these modalities remain susceptible to theft and duplication. Human odor, composed of complex volatile organic compound (VOC) profiles unique to each individual, is a promising alternative based on chemical information that is inherently more difficult to forge. This review article presents a comprehensive overview of human odor-based individual authentication, focusing on skin and breath odors, which can be easily and noninvasively collected. We examine the origins and characteristics of human odor components and review measurement techniques, including the canine olfactory systems, gas chromatography-mass spectrometry (GC-MS), and gas sensor arrays. Furthermore, we discuss key challenges and potential solutions for implementing odor-based authentication systems, underscoring their promise for secure, noninvasive personal identification.

基于气味的个人身份验证

为了满足日益增长的对安全和用户友好的个人身份验证方法的需求，生物识别技术已经被广泛采用，它比传统的基于密码或卡片的系统具有优势。虽然目前的生物识别系统主要依赖于指纹和面部结构等物理特征，但这些模式仍然容易被盗窃和复制。人体气味是由每个人独特的复杂挥发性有机化合物（VOC）组成的，是一种基于化学信息的有前途的替代品，这种化学信息本质上更难以伪造。本文综述了基于人体气味的个人身份认证，重点介绍了易于无创收集的皮肤和呼吸气味。我们研究了人类气味成分的起源和特征，并回顾了测量技术，包括犬嗅觉系统，气相色谱-质谱（GC-MS）和气体传感器阵列。此外，我们还讨论了实现基于气味的身份验证系统的主要挑战和潜在解决方案，强调了它们对安全、非侵入性个人身份识别的承诺。
