Abstract
Biometric data, suitably transformed are obtained from a biometric input device contained within a stand-alone computing device and used in conjunction with a PIN to authenticate the user to the device. The biometric template and other data residing on the device are encrypted using hardware elements of the device, the PIN and Password hash. A stored obfuscated password is de-obfuscated and released to the device authentication mechanism in response to a successfully decrypted template and matching biometric sample and PIN. The de-obfuscated password is used to authenticate the user to device, the user to a remote computer, and to encrypt device data at rest on the device and in transit to and from the remote computer. This creates a trusted relationship between the stand-alone device and the remote computer. The system also eliminates the need for the user to remember and enter complex passwords on the device.
