Write-protection module and method for storage device
First Claim
1. A storage device having a user identification function, comprising:
- a power supply module, for providing a working power, and the power supply module comprising;
a first power unit, for providing a power;
a second power unit; and
a power controller, coupled to the first power unit and the second power unit, for charging the second power unit according to the power and outputting the working power;
a user identification module, coupled to the power controller of the power supply module, for receiving the working power and a user'"'"'s identity information, and the user identification module generating a comparison information according to the user'"'"'s identity information; and
a control unit, coupled to the user identification module, for determining whether or not the user may access the storage device according to the comparison information;
wherein when the storage device is in a standby mode, the first power unit supplies the working power to the user identification module through the power controller, and charges the second power unit;
when the user identification module is activated, the second power unit supplies the working power required by an operation of encryption or decryption.

Abstract
A write-protection module for a storage device and the method thereof are disclosed. The write-protection module includes a power supply circuit, a fingerprint sensor, a database, and a microprocessor. The microprocessor for receiving the working power produced by the power supply circuit to maintain operation is respectively coupled to the power supply circuit, the fingerprint sensor, and the database. The fingerprint sensor receives the fingerprint input of a user, and the microprocessor receives the output signal of the fingerprint sensor and converts the output signal into an input cryptograph. Finally, the microprocessor compares the input cryptograph with a predetermined cryptograph stored in the database to produce a comparison information, and determines whether or not the user may access data.
