Systems, apparatus, and methods for continuous authentication

摘要

Systems, apparatus, and methods for continuously authenticating individuals are provided. A continuous authentication system receives first biometric authentication information from an individual. The system compares the first biometric authentication information to stored first biometric information to identify the individual and links the identified individual to a device for obtaining second biometric authentication information. The device for obtaining second biometric authentication information continuously receives second biometric authentication information. The continuous authentication system compares the received second biometric authentication information to stored second biometric information that corresponds to the individual to determine if the received second biometric authentication information corresponds to the individual. The individual may be granted access to one or more access points if it is determined that the received second biometric authentication information corresponds to the individual.

1. A method of continuously authenticating an individual, comprising:
acquiring first biometric authentication information from an individual; comparing the acquired first biometric authentication information to stored first biometric information to identify the individual; linking the identified individual with a device carried by the individual, the device including a wavelength-adjustable light source and a wavelength-adjustable light sensor for acquiring second biometric authentication information from the individual; continuously acquiring second biometric authentication information from the individual using the wavelength-adjustable light source and the wavelength-adjustable light sensor of the device, wherein continuously acquiring includes: irradiating, by the wavelength-adjustable light source, a skin part of the individual at a peak irradiation wavelength corresponding to a skin molecule; and detecting, by the wavelength-adjustable light sensor, within a peak detection wavelength band corresponding to the skin molecule, at least one of an intensity of reflection or an intensity of absorbance associated with the irradiated skin part; comparing the continuously acquired second biometric authentication information, acquired in accordance with the irradiating and the detecting at least one of the intensity of reflection or the intensity of absorbance, to stored second biometric information which includes stored data related to the skin molecule that corresponds to the identified individual; and authenticating the identified individual based on the comparison.
