Abstract
A system and method provide efficient, secure, and highly reliable authentication for transaction processing and/or access control applications. A personal digital key (PDK) is programmed using a trusted programming device to initialize and/or register the PDK for use. In one embodiment, the initialization and registration processes are administered by a specialized trusted Notary to ensure the processes follow defined security procedures. In a biometric initialization, the programming device acquires a biometric input from a user and writes the biometric data to a tamperproof memory in the PDK. In registration, the Programmer communicates to one or more remote registries to create or update entries associated with the user PDK. Once initialized and registered, the PDK can be used for various levels of secure authentication processes.
