Abstract

A biometric parameters protected computer serial bus interface portable data storage device which integrates the computer serial bus interface with biometric (Fingerprint) technologies to ensure data and information storage within the device are secured with personal biometrics information. The storage device acts as a portable hard disk which can be connected via computer serial bus interface onto any computer platform with computer serial bus host and only the user(s) with the authorized fingerprint bio-data can have access to the data stored in the device.

Claims

1. A biometric parameters protected computer serial bus interface portable data storage device comprising:

an embedded fingerprint biometrics processing unit and sensor;

a flash memory for data and information storage and with any storage capacity;

a micro-controller and data processing unit for interfacing with the embedded fingerprint system, a host computer system and the flash memory;

a built-in proprietary data encryption scheme for data and information safe-keeping within the flash memory; and

a proprietary enrollment scheme for biometric fingerprint enrollment.

2. The biometric parameters protected computer serial bus interface portable data storage device of claim 1, wherein the embedded fingerprint biometrics processing unit includes a biometrics processing unit and a bio-data storage unit.

3. The biometric parameters protected computer serial bus interface portable data storage device of claim 1, wherein the biometrics processing unit reads fingerprint bio-data from the fingerprint sensor and stores the bio-data into the bio-data storage unit in the form of an encryption key.

4. The biometric parameters protected computer serial bus interface portable data storage device of claim 2, wherein the bio-data storage unit stores user'"'"'s fingerprint bio-data.

5. The biometric parameters protected computer serial bus interface portable data storage device of claim 1, wherein the micro-controller and data processing unit includes an access control decision unit and a data processing unit.

7. The biometric parameters protected computer serial bus interface portable data storage device of claim 1, wherein the typical biometrics verification and system access time is approximately 1 second or less.

8. The biometric parameters protected computer serial bus interface portable data storage device of claim 1, wherein the biometrics enrollment time is 1 second per fingerprint, and not more than 25 fingerprints are assigned for authority access right.

6. A method of proprietary data bio-encryption method using biometric parameters protected computer serial bus interface portable data storage device comprising the steps of:

scanning user'"'"'s fingerprint by the fingerprint sensor;

processing the scanned fingerprint image by the biometrics processing unit which verifies the image with the user(s) fingerprint bio-data which is stored as encryption key(s) in the bio-data storage unit;

requesting another fingerprint for scanning again from the user if the verification fails;

preparing an encryption pointer which retrieves the encryption key from a bio-data storage unit if the verification is successful; and

securing the encryption key being retrieved in a polynomial appending process.
