Biometric-based Computer Authentication during Mission Oriented Protective Posture Scenarios

Military Oriented Protective Posture (MOPP) gear level IV is the most protective full-protection chemical protective gear for warfighters against chemical and biological threats. However, it is the most encumbered and inhibiting to the warfighter"s movement, visual horizon, and finger dexterity. Here, we propose a novel and continuous biometric-based system that provides a warfighter, in full protective MOPP gear, the ability to walk up to the networked computer host and be automatically authenticated into the machine. Our proposed system is to use a small, portable, and non-intrusive device, which has the functionalities of three-factor authentication, including"something we know","something we have"and"something we are", respectively. The novelty and uniqueness of our proposed system are as follows: First, it utilizes three-factor authentication approach which is more difficult to compromise than single-factor methods and guarantee the security level when accessing the network or host computer; Second, it employs a new concept of continuous biometrics approach, that is to verify a person based on human scent (odor), EEG/ECG, which guarantees minimum interaction of the warfighter and makes the authentication communication simple to use. Third, we propose multimodal biometrics fusion approaches which guarantees improved overall performance.
