To address the Army need for biometric authentication and access management for medics and casualty identification on Android platforms, Physical Optics Corporation (POC) proposes to advance the development of Android Biometric Authentication and Casualty Identification (ABACI) technology, based on the successful validation of the Phase I prototype. With the use of highly integrated multisensor hardware, along with Android-based software modules, the ABACI system is capable of dynamically utilizing one or more sensors (fingerprint, iris, palm, and vein) for authenticating medics on medical devices, providing role-based access to secure medical data. Furthermore, the ABACI module establishes a biometric identity for soldiers and civilians during noncombat situations and nonemergency medical care. Specifically, the unique design of the add-on sensor module and algorithms facilitates rapid, robust, seamless user authentication during combat without the use of authentication mechanisms such as common access cards (CACs), pins, passwords, and physical authentication tokens. The Phase II efforts will focus on leveraging the Phase I hardware and software design and developing a rugged prototype deployed on Android Nett Warrior end user devices (EUDs). The role-based authenticated access for medics to eTCCC and other medical applications and biometric identity establishment for simulated casualties in relevant environments will be demonstrated.
