Portable storage device using fingerprint recognition, and control method thereof

摘要

Disclosed is a portable storage device including a fingerprint sensor, a fingerprint data processing unit, a data repository, a data processing unit and the like. The fingerprint data processing unit outputs a fingerprint matching signal when fingerprint information received from the fingerprint sensor matches authentication fingerprint information of the fingerprint data repository. If the fingerprint matching signal is received from the fingerprint data processing unit, the data processing unit retrieves a data requested by the user terminal from the data repository, converts the retrieved data into a read-only data and transmits the read-only data to the user terminal.

1. A portable storage device using fingerprint recognition, the device comprising:
a fingerprint sensor for receiving fingerprint information; a fingerprint data repository for storing authentication fingerprint information; a fingerprint data processing unit for outputting a fingerprint matching signal when the fingerprint information received from the fingerprint sensor matches the authentication fingerprint information of the fingerprint data repository; a communication control unit for controlling communication with a user terminal; a firmware repository for storing firmware and a management program including a read-only conversion program for driving the portable storage device; a data repository for storing data; a data processing unit for retrieving a data requested by the user terminal from the data repository, converting the retrieved data into a read-only data, and transmitting the read-only data to the user terminal under the control of the communication control unit, if the fingerprint matching signal is received from the fingerprint data processing unit; a function button for providing a firmware repository area to the user terminal in a form of CD-ROM and allowing the management program in the firmware repository area to be used when user authentication is succeeded; an encryption/decryption engine for encrypting and decrypting a data in hardware when the data is stored in and retrieved from the data repository; and an initialization button, wherein an initialization process performed by the initialization button is performed only when the data processing unit receives the fingerprint matching signal from the fingerprint data processing unit, and wherein the data processing unit transmits a file list of the security data storage area to the user terminal only when the fingerprint matching signal is received from the fingerprint data processing unit.
