Identification authentication scheme using human body odour

Identity authentication is an important component of the security application system to access the available resources. To improve performance of Identification authentication, this paper presents a novel authentication scheme, which collects human body odour using gas sensor arrays, then detects and analyzes human body odour by Gas Chromatography & Mass Spectrometry, Principle Component Analysis, Neural Network and other pattern identification technologies to confirm the identity. Theoretical analysis indicates the scheme satisfies security, feasibility and effectiveness.
