Push type fingerprint lock storage device 【0001】

This creation is related to storage devices, especially regarding push-type fingerprint lock storage devices.

【0002】

Fingerprint recognition is the most popular biometric technology in recent times. By using the fingerprint sensor to capture the unique fingerprint data of the user and as the verification password of the electronic device, the security of the electronic device can be effectively improved, and the verification password can be prevented from being stolen.

[0003]

Please refer to FIG. 1A-1B at the same time. FIG. 1A is a schematic diagram of a conventional sliding fingerprint lock flash drive, and FIG. 1B is a schematic diagram of a segment fingerprint image generated by FIG. 1A. As shown in FIG. 1A, the conventional sliding fingerprint lock flash drive 1 includes a connector 10 and a sliding fingerprint image sensor 12. When the user connects the connector 10 to an external device (not shown), it is not possible to directly operate the external device to access the data in the conventional sliding fingerprint lock flash drive 1. The user still needs to input the correct fingerprint image through the sliding fingerprint image sensor 12 to unlock the conventional sliding fingerprint lock flash drive 1 to operate the external device to access the conventional sliding fingerprint lock flash drive 1 data.

[0004]

When the user wants to input the fingerprint image, the finger 14 is stably slid in the specific direction (eg, from top to bottom) through the sliding fingerprint sensor 12, so that the sliding fingerprint sensor 12 performs the fingerprint of the user. The continuous image is captured and produces a plurality of segment fingerprint images 16A-16D as shown in FIG. 1B. Next, the conventional sliding fingerprint lock flash drive 1 splices a plurality of segment fingerprint images 16A-16D to generate a complete fingerprint image.

[0005]

However, when the speed of the user's finger 14 sliding over the sliding fingerprint sensor 12 is unstable (such as too fast, too slow or too fast), the conventional sliding fingerprint lock flash drive 1 will be captured. The complex segment fingerprint image 16A-16D has flaws (if the partial segment fingerprint image 16A-16D is not matched), and the complex segment fingerprint image 16A-16D cannot be correctly stitched, which eventually leads to the unlock failure.

[0006]

For example, since the speed of the image captured by the sliding fingerprint sensor 12 is usually a fixed value, when the sliding speed is greater than the speed of capturing the image, a part of the fingerprint of the user is not captured, and no The complete multiple segment fingerprint image 16A-16D failed to be unlocked due to the inability to splicing into a complete fingerprint image. When the sliding speed is lower than the image capturing speed, the captured plurality of segment fingerprint images 16A-16D content will be repeated, and the unlocking fails due to the inability to splicing.

【0007】

In addition, since the conventional sliding fingerprint lock flash drive 1 has a low verification success rate, the user often needs to slide the finger 14 several times on the sliding fingerprint sensor 12 to unlock the conventional sliding fingerprint lock flash drive 1. The aforementioned frequent sliding use mode will cause wear of the sliding fingerprint sensor 12, and the service life of the sliding fingerprint sensor 12 is greatly shortened, and the recognition rate is lowered.

[0008]

As described above, the conventional sliding type fingerprint lock flash drive has the above-mentioned inconvenience in use and sensor wear problems, and a solution to be more effective is proposed.

【0009】

The main purpose of this creation is to provide a fingerprint lock storage device that can input fingerprint images without sliding a finger.

[0016]

[0017]

Still further, the drive electrode 220 is a metal frame and is disposed around the sensing electrode 222 to form a fingerprint sensing area. The sensing electrode 222 includes a plurality of sensing points disposed in the fingerprint sensing area.

[0033]

When the user presses the fingerprint sensing area with a finger (the finger 14 shown in FIG. 3A), since the fingerprint includes a plurality of fingerprint peaks (FP) and a plurality of fingerprint valleys (FV), when the driving signal flows through the fingerprint When in the position, it will be affected by the ripple or grain, and different sensing values (such as resistance value or capacitance value) will be generated at different sensing points. Next, the sensing electrode 222 uses the aforementioned complex sensed value as a sensing signal and outputs it to the microcontroller 28.

[0034]

The memory unit 24 is used to store data. Specifically, the memory unit 24 stores the holder fingerprint image 240 and the at least one guest fingerprint image 242, wherein the holder fingerprint image 240 corresponds to the fingerprint of the holder of the push-type fingerprint lock storage device 2, and the guest fingerprint image 242 It corresponds to the fingerprint of the user who has been authorized by the holder to use the push-type fingerprint lock storage device 2 (in the following description, since the guest indicates).

[0035]

Also, the memory unit 24 includes a secure storage area 244. The secure storage area 244 is set to prohibit access by the external device 40 under normal circumstances (eg, the user does not pass fingerprint verification); in the case of verification pass (eg, the user authenticates by fingerprint), the secure storage area 244 will be set to Access to the external device 40 is acceptable. Thereby, the secure storage area 244 can store the sensitive information. Preferably, the memory unit 24 is a flash memory, a hard disk drive (HDD), or an electronically erasable programmable read-only memory (Electrically-Erasable Programmable Read-Only Memory). , EEPROM) or a combination of the above, but not limited to this.

[0036]

Switching element 26 is operative to accept user operations to trigger microcontroller 28 to perform various functions (described in detail later). Preferably, the switching element 26 is a touch panel or a physical button, but is not limited thereto. When the switching element 26 is a physical button, the user can trigger the microcontroller 28 to perform a particular function by pressing the physical button for a particular pressed time or pressing the physical button at a particular pressing frequency. Moreover, the microcontroller 28 can distinguish different operations input by the user according to the pressed time or the pressing frequency of the aforementioned buttons, such as a security access operation, a holder login operation, a guest login operation, and a deletion fingerprint operation. Said). In another embodiment of the present invention, the switching element 26 can also be a plurality of physical buttons, and each physical button corresponds to a different function.

[0037]

The microcontroller 28 is used to control the push-type fingerprint lock storage device 2. Specifically, the microcontroller 28 includes a processing module 280 and a secure access module 282. The processing module 280 can obtain the sensing signal from the pressing fingerprint sensor 22, convert the sensing signal to press the fingerprint image, and temporarily store the pressing fingerprint image to the memory unit 24 for subsequent comparison.

[0038]

The secure access module 282 is coupled to the processing module 280 to provide a secure storage area unlocking function. When the connector 20 is connected to the external device 40, the secure access module 282 continues to detect whether the switching element 26 accepts a secure access operation from the user. When the switching component 26 receives the secure access operation, the secure access module 282 obtains the pressed fingerprint image currently input by the user via the processing module 280, and determines the fingerprint image of the holder that is pre-stored by pressing the fingerprint image and the memory 24. 240 or whether the guest fingerprint image 242 matches.

[0039]

The secure access module 282 allows the secure storage area 244 to be accessed by the external device 40 if the pressed fingerprint image matches one of the holder fingerprint image 240 or the guest fingerprint image 241. If the pressed fingerprint image does not match the holder fingerprint image 240 or the guest fingerprint image 242, the secure access module 282 prohibits the secure storage area 244 from being accessed by the external device 40, and may further send an alert message to the external device 40 for display. Or, an alert message is sent via other components of the push-type fingerprint lock storage device 2. Thereby, only the authenticated user can access the smart data stored in the secure storage area 244 via the external device 40, thereby effectively improving the security of the smart data.

[0040]

In another embodiment of the present invention, the push-type fingerprint lock storage device 2 further includes an indicator light 30 electrically connected to the microcontroller 28. The indicator light 30 is used to indicate the current state of the fingerprint lock storage device or to send a message (such as the aforementioned warning message). Preferably, the indicator light 30 is a Light-Emitting Diode (LED) indicator light and can indicate different current status or issue different messages by emitting different color lights or continuously lighting different times.

[0041]

In another embodiment of the present creation, memory unit 24 further includes a common storage area 246. The common storage area 246 can be directly accessed by the external device 40 after the connector 20 is connected to the external device 40 without fingerprint verification. The creation can effectively improve the flexibility of use of the pressed fingerprint lock storage device of the present invention by dividing the storage space of the memory into a secure storage area 244 for restricting access and a common storage area 246 for restricting access.

[0042]

In another embodiment of the present invention, the microcontroller 28 further includes a holder login module 284 coupled to the processing module 280 to provide a holder fingerprint login function. The holder registration module 284 can continuously detect whether the switching element 26 accepts the holder login operation from the user. When the switching component 26 accepts the owner login operation, the holder registration module 284 obtains the pressed fingerprint image currently input by the user via the processing module 280, and sets the pressed fingerprint image as the holder fingerprint image 240, and The holder fingerprint image 240 is stored to the memory 24.

[0043]

In another embodiment of the present invention, the microcontroller 28 further includes a guest login module 286 coupled to the processing module 280 to provide a guest fingerprint login function. The guest login module 286 can continuously detect whether the switching element 26 accepts a guest login operation from the user. When the switching component 26 accepts the guest login operation, the guest login module 286 first obtains the pressed fingerprint image currently input by the user (here, the holder) via the processing module 280, and determines that the fingerprint image and the memory 24 are pre-pressed. Whether the stored holder fingerprint image 240 matches. If the pressed fingerprint image does not match the holder fingerprint image 240, the guest login module 286 suspends the subsequent processing, and sends an alert message to the external device 40 for display, or the control indicator 30 issues a warning message.

[0044]

If the pressed fingerprint image matches the holder fingerprint image 240, the guest registration module 286 acquires another pressed fingerprint image currently input by another user (here, the guest) via the processing module 280, and sets the pressed fingerprint image. The guest fingerprint image 242 is stored and the guest fingerprint image 242 is stored in the memory 24.

[0045]

In another embodiment of the present invention, the microcontroller 28 further includes a delete fingerprint module 288 to provide the holder to delete the holder fingerprint image 240 and all the guest fingerprint images that have been stored in the push fingerprint lock storage device 2. 242 fingerprint deletion function. The delete fingerprint module 288 is connected to the processing module 280 to continuously detect whether the switching element 26 accepts the delete fingerprint operation from the user. When the switching component 26 accepts the fingerprint deletion operation, the deletion fingerprint module 288 can obtain the pressed fingerprint image currently input by the user via the processing module 280, and determine the fingerprint image 240 of the holder fingerprint stored in advance by the fingerprint image and the memory 24. Whether it matches. If the pressed fingerprint image matches the holder fingerprint image 240, the deleted fingerprint module 288 determines that the current user is the holder, and deletes the holder fingerprint image 240 and all the guest fingerprint images 242 stored in the memory unit 24. .

[0046]

If the pressed fingerprint image does not match the holder fingerprint image 240, the deleted fingerprint module 288 suspends the subsequent processing, and sends an alert message to the external device 40 for display, or the control indicator 30 issues a warning message.

[0047]

3A-3B, FIG. 3A is a schematic diagram of the use of the push-type fingerprint lock storage device according to the first embodiment of the present invention, and FIG. 3B is a schematic diagram of the pressed fingerprint image generated by FIG. 3A. In this embodiment, the push-type fingerprint lock storage device 2 is a fingerprint lock flash drive, the connector 20 is a universal serial bus (USB) port, the switch component 26 is a button, and the indicator light 30 is a light-emitting diode (LED). Indicator light. The driving electrode 220 is a metal frame disposed around the sensing electrode 222, and the surrounding area of the metal frame is a fingerprint sensing area. After the user presses the fingerprint sensing area with the finger 14, the push type fingerprint lock storage device 2 can generate the pressed fingerprint image 32 as shown in FIG. 3B and perform subsequent processing.

[0048]

When the push-type fingerprint lock storage device 2 is connected to the external device 40 through the connector 20, after the external device 40 takes power and is activated, the user can operate the switching element 26 to trigger the push-type fingerprint lock storage device 2 to perform different functions. For example, if the user wants to log in to the holder's fingerprint, the switching element 26 can be pressed for about 3 seconds to trigger the push-type fingerprint lock storage device 2 to perform the holder fingerprint registration function. At this time, the indicator light 30 alternately flashes red-blue light to prompt the user to press the fingerprint on the push-type fingerprint sensor 22. Next, the user presses the fingerprint sensing area of the sensing electrode 222 with the finger 14 to input a fingerprint pressing operation, so that the pressed fingerprint lock storage device 2 acquires the pressed fingerprint image to perform subsequent operations.

[0049]

If the push-type fingerprint lock storage device 2 successfully executes the holder fingerprint registration function, the indicator light 30 is turned from blinking red-blue light to constant-bright blue light for about 2 seconds, and then extinguished; if the push-type fingerprint lock storage device 2 executes the holder If the fingerprint login function fails (such as fingerprint input failure), the indicator light 30 is turned from blinking red-blue light to constant-bright red light for about 2 seconds and then extinguished.

[0050]

If the user wants to log in the guest fingerprint, the switching element 26 can be pressed for about 3 seconds to trigger the push fingerprint lock storage device 2 to perform the guest fingerprint registration function. At this time, the indicator light 30 flashes blue light to prompt the holder to press the fingerprint. If the fingerprint pressed by the user matches the holder fingerprint image 240, the indicator light 30 is converted from flashing blue light to blinking red-blue light to prompt the guest to press the fingerprint. If the fingerprint fingerprint lock storage device 2 successfully performs the guest fingerprint registration function, the indicator light 30 turns off from blinking red-blue light to constant-bright blue light for about 2 seconds; if the push-type fingerprint lock storage device 2 fails to perform the guest fingerprint login function ( If the fingerprint image 240 of the holder does not match or the fingerprint input of the user fails, the indicator light 30 changes from blinking blue light to constant red light for about 2 seconds (when the holder fingerprint image 240 does not match) Or, from flashing red and blue light to constant red light, turn off after about 2 seconds (when the user's fingerprint input fails).

[0051]

If the user wants to unlock the secure storage area 244, the switching element 26 can be pressed shortly for about 0.5 seconds to trigger the push-type fingerprint lock storage device 2 to perform the secure storage area unlocking function. The push-type fingerprint lock storage device 2 controls the indicator light 30 to blink blue light to prompt the user to press the fingerprint. If the push-type fingerprint lock storage device 2 successfully performs the secure storage area unlocking function (for example, if the user presses the fingerprint and the holder fingerprint matches the holder fingerprint image 240 or matches the guest fingerprint image 242), the indicator light 30 is The flashing blue light is turned into a constant blue light for about 2 seconds, and then extinguished; if the push fingerprint lock storage device 2 performs the guest fingerprint registration function fails (if the fingerprint pressed by the user does not match the holder fingerprint image 240 and the guest fingerprint image 242 If the fingerprint does not match, or the fingerprint input fails, the indicator light 30 turns off from blinking blue light to constant red light for about 2 seconds.

[0052]

Further, the push-type fingerprint lock storage device 2 can determine the fingerprint login function or the guest fingerprint of the holder when the login fingerprint of the login holder or the login fingerprint fails for three consecutive times (for example, the user inputs the wrong fingerprint three times in succession). The login function fails to execute, and the indicator light 30 will be solid red for about 2 seconds and then turned off.

[0053]

This creation can further provide secure storage area locking. After the user completes the data access to the unlocked secure storage area 244 via the external device 40, the switching element 26 can be briefly pressed for about 0.5 seconds to trigger the push-type fingerprint lock storage device 2 to perform the secure storage area locking function. The push-type fingerprint lock storage device 2 controls the indicator light 30 to blink blue light to prompt the user to press the fingerprint. If the push-type fingerprint lock storage device 2 successfully performs the secure storage area lock function (for example, if the user presses the fingerprint and the holder fingerprint matches the holder fingerprint image 240 or matches the guest fingerprint image 242), the push-type fingerprint lock The storage device 2 locks the secure storage area 244, and the indicator light 30 is turned from blinking blue light to constant blue light for about 2 seconds, and then extinguished; if the push-type fingerprint lock storage device 2 fails to perform the secure storage area locking function (such as the user presses If the fingerprint does not match the holder fingerprint image 240 and does not match the guest fingerprint image 242, or the fingerprint input fails, the indicator light 30 turns off from blinking blue light to constant red light for about 2 seconds.

[0054]

This creation can further provide automatic locking of the secure storage area. When the secure storage area locking function has been successfully executed (ie, the secure storage area 244 has been unlocked) and the connection between the push-type fingerprint lock storage device 2 and the external device 40 is interrupted (eg, the user removes the push-type fingerprint lock storage device 2) The push-type fingerprint lock storage device 2 can automatically lock the secure storage area 244. In other words, when the user wants to access the secure storage area 244 again, the secure storage area unlocking function needs to be re-executed to unlock the secure storage area 244. Therefore, the creation can effectively avoid the information security problem caused by the user not performing the secure storage area locking function (for example, if the security fingerprint storage device 2 is stolen, if the secure storage area 244 is not locked, the thief can be caused by the thief. Free access to the data stored in the secure storage area 244).

[0055]

The present invention further provides a fingerprint management method for a user to manage the push-type fingerprint lock storage device 2 by operating the external device 40.

[0056]

Please refer to FIG. 4 , which is a flowchart of a fingerprint management method according to a first specific embodiment of the present invention. The fingerprint management method of this embodiment is mainly applied to the push type fingerprint lock storage device 2 and the external device 40 shown in FIG. 2. The external device 40 of this embodiment further includes a human interface (such as a touch screen or a combination of a display screen and a mouse).

[0057]

In this embodiment, the external device 40 determines whether the push-type fingerprint lock storage device 2 is connected (step S400). If the push-type fingerprint lock storage device 2 is not connected, step S400 is repeatedly performed to continuously detect; if the push type is connected The fingerprint lock storage device 2 displays the operation interface via the human machine interface (step S402). Preferably, the foregoing operation interface is a Graphical User Interface (GUI).

[0058]

Next, the external device 40 detects whether the human machine interface accepts the viewing fingerprint state operation from the user (step S404). If the human-machine interface accepts the viewing fingerprint state operation from the user, the external device 40 acquires the fingerprint status information from the pressed fingerprint lock storage device 2, and displays the fingerprint status information on the human-machine interface (step S406). In this embodiment, the fingerprint status information includes the number of the holder fingerprint image 240 and the guest fingerprint image 242 stored in the memory unit 24 of the push fingerprint lock storage device 2.

[0059]

If the human interface does not accept the fingerprinting state operation from the user, the external device 40 further detects whether the fingerprint fingerprint storage device 2 has stored the holder fingerprint image 240 (step S408). If the fingerprint fingerprint storage device 2 does not store the holder fingerprint image 240, the aforementioned fingerprint registration function can be executed to cause the memory unit 24 to store the holder fingerprint image 240 (step S410). Specifically, after the fingerprint fingerprint lock storage device 2 executes the holder fingerprint registration function, the pressed fingerprint image of the user (here, the holder) can be obtained via the push fingerprint sensor 22, and the obtained pressed The fingerprint image is taken as the holder fingerprint image 240 and stored to the memory unit 24.

[0060]

If the fingerprint fingerprint storage device 2 has stored the holder fingerprint image 240 or has performed the aforementioned fingerprint registration function successfully, the external device 40 further detects whether the human interface accepts the guest login operation from the user (steps) S412). If the human machine interface accepts the guest login operation from the user, the external device 40 transmits the guest login trigger signal to the push fingerprint lock storage device 2 to trigger the push fingerprint lock storage device 2 to execute the guest fingerprint login function.

[0061]

After the push-type fingerprint lock storage device 2 is triggered by the guest registration trigger signal, the pressed fingerprint sensor 22 acquires the pressed fingerprint image of the user (here, the holder) (step S414). Then, the pressed fingerprint lock storage device 2 compares the obtained pressed fingerprint image with the holder fingerprint image 240 prestored in the memory 24 to determine whether the pressed fingerprint image matches the holder fingerprint image 240 (step S416) ). If the push fingerprint lock storage device 2 determines that the pressed fingerprint image does not match the holder fingerprint image 240, the fingerprint management method ends. If the push fingerprint lock storage device 2 determines that the pressed fingerprint image matches the holder fingerprint image 240, the push fingerprint lock storage device 2 obtains another user (here, the guest) via the push fingerprint sensor 22 The fingerprint image is pressed, and the obtained pressed fingerprint image is taken as the guest fingerprint image 242 and stored in the memory 24 (step S418).

[0062]

If the human interface does not accept the guest login operation from the user in step S412, the external device 40 further detects whether the human interface accepts the fingerprint deletion operation from the user (step S420). If the detecting human interface does not accept the fingerprint deletion operation from the user, then the process goes to step S404 to perform continuous detection. If the human interface accepts the fingerprint deletion operation from the user, the external device 40 transmits the delete fingerprint trigger signal to the push fingerprint lock storage device 2 to trigger the push fingerprint lock storage device 2 to perform the delete fingerprint function.

[0063]

After the push-type fingerprint lock storage device 2 is triggered by the deleted fingerprint trigger signal, the pressed fingerprint image is obtained by the user (here, the holder) via the push-type fingerprint sensor 22 (step S422). Then, the pressed fingerprint lock storage device 2 compares the obtained pressed fingerprint image with the holder fingerprint image 240 prestored in the memory 24 to determine whether the pressed fingerprint image matches the holder fingerprint image 240 (step S424) ). If the push fingerprint lock storage device 2 determines that the pressed fingerprint image does not match the holder fingerprint image 240, the fingerprint management method ends. If the push fingerprint lock storage device 2 determines that the pressed fingerprint image matches the holder fingerprint image 240, the push fingerprint lock storage device 2 deletes the holder fingerprint image 240 stored in the memory 24 and all the guest fingerprint images 242 (steps) S426).

[0064]

The use of a push-type fingerprint sensor to obtain a fingerprint image can effectively improve the probability of successfully acquiring a fingerprint image and can effectively reduce the wear of the fingerprint sensor.

[0065]
