More Information
Summary:Hyperspectral imaging (HSI) of biofluids for biometric applications is disclosed. A HSI device scans a region of a human subject's skin with sweat thereon, without requiring the human subject to touch any surface. The resulting HSI data is processed to identify aspects of the data that represent physical and/or chemical features that uniquely identify the subject. Processing the HSI data includes identifying one or more particular metabolites in the subject's sweat by analyzing wavelengths which those metabolites reflect. Processing the HSI data includes identifying one or more glands beneath the outermost surface of the subject's skin based on HSI-detected wavelength reflectance and wavelength penetration. The disclosed system may generate and store an identity profile corresponding to a human's unique identity features, as determined based on the HSI data processing. A subject's identity is verified by comparing subsequent HSI scans of his skin with sweat thereon to his stored identity profile.
