[0012] The following further describes the utility model with reference to the drawings and embodiments.

[0013] Figure 1This is a schematic diagram of the system structure of the present utility model. Detailed implementation mode

[0014] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the following will combine the accompanying drawings in the embodiments to more clearly and completely elaborate the present utility model. Of course, the described embodiments are only a part rather than all of the present utility model. Based on this embodiment, other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present utility model.

[0015] As shown in the figures, a fingerprint-unlocking mobile hard disk includes:

[0016] A USB bridge chip for connecting the device to the hard disk to read the hard disk content;

[0017] An MCU chip is arranged on the USB bridge chip circuit to control the power supply and signals of each component; after unlocking, the MCU chip directly supplies power to the USB bridge chip to read the hard disk content and no longer supplies power to the buzzer and fingerprint module;

[0018] A fingerprint module for collecting, storing, deleting, and verifying the fingerprint signals of users. After verification, the MCU chip supplies power to the USB bridge chip;

[0019] A signal switch is arranged on the USB bridge chip to distribute the power supply signal of the MCU chip.

[0020] The MCU chip is connected to a buzzer; the buzzer completes the prompts for fingerprint entry, unlocking, and deletion by emitting a "beep" prompt sound and changing the color of a multi-color LED indicator.

[0021] The buzzer is powered by the MCU chip, and the power supply signal is distributed through the signal switch.

[0022] The MCU chip is bidirectionally connected to the signal switch, and the signal switch and the USB bridge chip are bidirectionally connected.

[0023] The fingerprint module is provided with a multi-color LED indicator, and the multi-color LED indicator is powered by the MCU chip.

[0024] A usage method of a fingerprint-unlocking mobile hard disk, the method includes the following steps:

[0025] The first step: Connect the mobile hard disk to the device, and the multi-color LED indicator shows the first color;

[0026] Step 2: Press any finger on the fingerprint module. The multi-color LED indicator will switch to the second color. After the buzzer makes one beep, the hard drive will be unlocked. When there is no fingerprint or less than 2 fingerprints are recorded in the fingerprint module, any finger pressing the fingerprint module can unlock the hard drive. When there are 2 or more fingerprints recorded, the hard drive needs to match the recorded fingerprints to be unlocked.

[0027] Step 3: For fingerprint recording, press the fingerprint module to record a fingerprint. After the buzzer makes two beeps and the multi-color LED indicator switches to the third color, release the finger. At this time, the multi-color LED indicator switches to the fourth color to enter the recording mode. Repeat the pressing again. Release the finger after each press when the buzzer makes one beep until the multi-color LED indicator shows the fifth color and then stop recording, indicating that the recording is completed. The preferred number of repeated presses is 8 times.

[0028] Step 4: After changing the finger, repeat the operation in Step 2 to record the fingerprint.

[0029] Step 5: After recording multiple fingerprints, press any finger that has been recorded on the fingerprint module. After successful matching, the multi-color LED indicator switches to the second color. After the buzzer makes one beep, the hard drive will be unlocked. If there is no match, the multi-color LED indicator switches to the fourth color and the hard drive remains locked.

[0030] If the indicator switches to the sixth color and blinks and the buzzer continuously gives an alarm during Step 3 or Step 4, the fingerprint recording fails. When the recording fails, the buzzer preferably gives 5 consecutive beeps.

[0031] The following situations in fingerprint recording may cause the recording to fail: the number of fingerprints recorded exceeds the storage limit, the operation interval stop time is too long, the touch area is insufficient, or the finger moves during the operation and cannot be recognized. The preferred storage quantity is 20 fingerprints, and the preferred operation interval stop time is 30 seconds.

[0032] Deleting fingerprints includes the following steps:

[0033] Step 1: Press the fingerprint module. After the buzzer makes one beep and the multi-color LED indicator switches to the second color, continue to press.

[0034] Step 2: Continue to press the fingerprint module until the buzzer makes two beeps and the multi-color LED indicator switches to the third color, and then continue to press.

[0035] Step 3: Continue to press the fingerprint module until the buzzer makes three beeps and the multi-color LED indicator switches to the sixth color and blinks, and then continue to press.

[0036] Step 4: When the buzzer gives a long beep and switches to the seventh color after continuing to press, the fingerprint deletion is completed. The pressing time for each step above needs to be maintained for 4 seconds.

[0037] The fingerprint can be deleted through the background software; the functions of the background software include: displaying the device ID number and the number of fingerprints, unlocking, changing the password, and restoring the factory settings.

[0038] When the number of input fingerprints is less than two, the software will automatically open the hard disk and exit the interface. When the number of input fingerprints is greater than 2, the software needs to enter the password to open the hard disk; when restoring the factory state, the device fingerprints will be cleared and the background password will be initialized to the factory password. When deleting fingerprints through the fingerprint module, the password of the background software will also be restored to the factory password; if the fingerprint module fails, when unlocking the hard disk through the background software, the password must be entered.

[0039] In the first step, the multi-color LED indicator shows the first color and the multi-color LED indicator flashes; in the fifth step, the multi-color LED indicator shows the first color constantly on and shows the second color after unlocking.

[0040] The states represented by each color of the multi-color LED indicator are as follows:

[0041] The first color flashes: The fingerprint module has no input fingerprints or has 1 input fingerprint, and any fingerprint can unlock.

[0042] The first color is constantly on: The fingerprint module has input fingerprints greater than or equal to 2, and the corresponding fingerprint is required to unlock.

[0043] The second color: The hard disk is unlocked successfully.

[0044] The third color: Enter the fingerprint input state.

[0045] The fourth color: Start fingerprint input.

[0046] The fifth color: The fingerprint is input successfully.

[0047] The sixth color: Warning for deleting fingerprints or failure in fingerprint input.

[0048] The seventh color: Unlock failure or fingerprint clearing.

[0049] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments.
