Abstract:
1. A method for electronic authentication comprising: retrieving a biometric profile sample comprising transformed biometric information stored in a memory of a personal digital key (PDK), wherein the biometric profile sample is associated with a biometric profile and is based on less than the entirety of the biometric profile, and wherein the biometric profile is uniquely associated with an individual and is stored in the memory of the PDK; receiving a biometric input; receiving data for comparing the transformed information of the biometric profile sample to the biometric input; comparing the transformed information of the biometric profile sample to the biometric input; authorizing a transaction responsive to the transformed information of the biometric profile sample matching the biometric input; establishing a secure communication channel with a remote registry; transmitting PDK information to the remote registry using the secure communication channel, wherein the PDK information is uniquely associated with the PDK; receiving a validation decision from the remote registry using the secure communication channel, the validation decision indicating whether the remote registry determines if the PDK is valid or invalid; and determining if a transaction should be authorized based on (a) the validation decision and (b) the comparison between the biometric profile sample and biometric input, wherein the remote registry includes a database administered by a trusted third-party organization and the PDK is registered with the registry.
