Biometrics parameters protected USB interface portable data storage device with USB interface accessible biometrics processor
First Claim
1. A portable data storage device with USB accessible biometrics processor comprising:
- an embedded fingerprint biometrics processing unit and sensor, wherein the fingerprint biometrics processing unit is accessible externally by USB host and internally within the device;
a plurality of non-volatile solid state read/write memories for data and information storage;
a processor unit for interfacing with the embedded fingerprint system, a USB host and the non-volatile solid state read/write memories;
a data encryption or a data protection scheme for data and information safekeeping within the non-volatile solid state read/write memories; and
an enrollment scheme for biometric fingerprint enrollment.

Abstract
A biometric parameters protected USB interface portable data storage device which integrates generic USB interface with biometric (Fingerprint) technologies to ensure data and information storage within the device are secured with personal biometrics information. The biometric processing unit is securely accessed by USB host to perform various biometrics functionalities at the control of application software running in the PC or USB On-the-Go host. The biometrics functionalities include fingerprint scanning, fingerprint bio-data generation and encryption, comparison of fingerprint bio-data and storing of fingerprint bio-data. The storage acts as a portable hard disk that can only be accessed by the user(s) with the authorized fingerprint biodata and at the same time the USB accessible biometrics processing unit of the device offers unlimited application for the application software operating in PC host and USB On-the-Go devices.

8. A method of using a biometric parameters protected portable data storage device, said method comprising the steps of:
-
scanning user'"'"'s fingerprint by a fingerprint sensor;
processing the scanned fingerprint image by a biometrics processing unit which verifies the image with the user(s) fingerprint bio-data which is in a bio-data storage unit; and
requesting another fingerprint for scanning again from the user if the verification fails.
