In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

Please refer to FIG. 1. FIG. 1 is a flowchart of a multi-fingerprint authentication method according to an embodiment of the present invention. In Fig. 1, step S110 executes an authentication procedure. Please note here that, in the multi-fingerprint detection device of this embodiment, the fingerprint detection board can be configured to overlap with the display panel, and be configured directly below the display panel. Therefore, the fingerprint detection board in this embodiment has a relatively large area. Please refer to FIG. 1, FIG. 2A and FIG. 2B simultaneously. FIG. 2A and FIG. 2B are schematic diagrams of the configuration of the fingerprint detection board according to the embodiment of the present invention. In FIG. 2A, the fingerprint detection board 200 may be composed of a plurality of fingerprint detection elements TP11~TPMN. The fingerprint detection elements TP11~TPMN are arranged in an array. In FIG. 2B, the fingerprint detection board 200 can be divided into a plurality of detection areas 210-2A0. Please note here that each detection area 210-2A0 in FIG. 2B may include multiple fingerprint detection elements, and the detection areas 210-2A0 may be arranged in a vertical direction as shown in FIG. 2B. Alternatively, the detection areas 210-2A0 can also be arranged in parallel or in an array, without a fixed limit.

Please refer to FIG. 1 again. In step S120, in the authentication process, one or more of the detection areas 210-2A0 of the fingerprint detection board receive multiple detected fingerprint information. In detail, after the authentication process is activated, the user can perform a touch action for each of the multiple detection areas 210~2A0, and this touch action can be time-sharing multiple times for the same or different detection areas 210~2A0 for touch control. In addition, the user can use the same or different fingers to perform multiple touches for the same or different detection areas 210-2A0. For example, the user can use the first finger to press on the detection area 220 in the first time interval, and then, in the second time interval, use the second finger to press on the detection area 2A0, and In order to generate an input fingerprint information. Alternatively, the user can use the first finger to press on the detection area 210 in the first time interval, and then, in the second time interval, use the first finger to press on the detection area 220 to generate Another input fingerprint information. Alternatively, the user can use the first finger to press on the detection area 220 in the first time interval, and then, in the second time interval, use the second finger to press on the detection area 220 again, and thereby Generate another input fingerprint information.

Suppose there is a first case where at least one time interval without finger pressing is left in two time intervals with finger pressing, and it is exactly the same as the aforementioned pressing finger, except that there are no empty time intervals without finger pressing, but two The second case of the time interval during which there is continuous finger pressing. In one embodiment, the first situation and the second situation are determined to be exactly the same touch sequence, because the defined touch sequence does not include blank information, such as AB; in another embodiment, the electronic The device will determine that it is two different touch timings, because it records any blank time interval without finger pressing as zero or blank, so that the touch timings of the first case and the second case are, for example, A0 ...B and AB, or ANull...B and AB. In other embodiments, the touch sequence can also be defined as other ways of recording the time interval when there is no finger pressing. For example, recording more than one time interval as a single zero or blank, but the present invention does not take this as limit. The length of the above-mentioned blank time interval can be set by the designer, and there is no certain limit.

Please refer to FIG. 3 below. FIG. 3 is a schematic diagram of a multi-fingerprint authentication method according to an embodiment of the present invention. Among them, in the authentication process, the fingerprint detection board 300 can distinguish multiple detection areas FTZ1 to FTZ4 randomly distributed. When performing a multi-fingerprint authentication action, the display panel overlapped with the fingerprint detection board 300 can display the detection areas FTZ1 to FTZ4, and allows the user to perform multiple pressing actions on the fingerprint detection board 300 through the finger 310. The fingerprint detection board 300 performs fingerprint recognition for multiple pressing actions of the user in a time-sharing partition, and receives multiple detected fingerprint information. Then, the electronic device to which the fingerprint detection board 300 belongs can generate an activation command according to the respective detection areas corresponding to the obtained detected fingerprint information and the touch timing of the detected fingerprint information. And make the electronic device execute the corresponding setting function according to the start command.

Of course, in the embodiment of the present invention, when an error occurs in the fingerprint input, the electronic device cannot generate the activation based on the detection area corresponding to the obtained detected fingerprint information and the touch timing of the detected fingerprint information. Order. The electronic device does not perform an action, and the electronic device can receive a new fingerprint input action through the fingerprint detection board 300 again.

Incidentally, corresponding to a single activation command, the above-mentioned multiple detected fingerprint information can be completely different, partially the same, or completely the same. In addition, the detection areas corresponding to the above-mentioned detected fingerprint information are completely different, partially the same, or completely the same.

Please refer to FIG. 4, which is a flowchart of a registration procedure of the multi-fingerprint authentication method according to an embodiment of the present invention. First of all, before performing fingerprint authentication, you must first register for the corresponding setting function. Step S410 starts the registration procedure. Next, step S415 provides the user to set the authentication time. For example, the authentication time can be set to 0 seconds, 0.5 seconds... and so on. In step S420, a setting operation of the set number Num is performed. Step S430 determines whether the set number Num is greater than 0. If the set number Num is not greater than 0, it indicates that the setting of the set number Num is wrong, and step S410 is executed again. If step S430 determines that the set number Num is greater than 0, step S440 is executed.

In step S440, the count value Cnt is set, and the count value Cnt is equal to the set number Num. Step S450 determines whether the count value Cnt is greater than 0, and when the determination result is that the count value Cnt is greater than 0, the loop formed from step S450 to step S490 is executed. The number of loops is equal to the count value Cnt, and is the same as the amount of fingerprint information that the user needs to input in the registration process. The purpose of the loop formed from step S450 to step S490 is to confirm that the user has indeed completed all the fingerprint information input actions. Then, after the user performs the fingerprint input action, step S470 executes the detected fingerprint information obtained this time and whether the detection area is repeated. If the detected fingerprint information obtained this time and the detection area are repeated, execute In step S480, a warning signal is sent, and step S460 is executed again, and the fingerprint information input action is executed again. If it is determined in step S470 that the detected fingerprint information and the detection area obtained this time are not repeated, step S490 is executed to decrease the count value Cnt by one.

If it is determined in step S450 that the count value Cnt is not greater than 0, step S4100 can be executed to compare the received fingerprint-related information (detect fingerprint information, detect fingerprint information, respectively) corresponding to the detection area, and detect the occurrence of fingerprint information. Time sequence) to record, and compare the recorded fingerprint-related information with the fingerprint-related information that has been registered previously to confirm whether the fingerprint-related information in this registration process is duplicated. If the fingerprint-related information in the registration procedure this time is repeated, the registration procedure executed this time is invalid, and step S410 is executed again. On the contrary, if the fingerprint-related information in this registration process is not repeated, the received fingerprint-related information is recorded as the registered fingerprint information in a database, and the registration process is completed (step S4110).

Regarding the implementation details of step S4100, the database can be read first, and a plurality of previously detected fingerprint information, a plurality of previously detected areas corresponding to the previously detected fingerprint information, and a previous touch sequence (that is, Fingerprint related information that has been registered previously). Next, determine the detection area corresponding to the above-mentioned detected fingerprint information and detected fingerprint information, and the touch timing (the fingerprint-related information this time), respectively, corresponding to the previous detected fingerprint information and the previously detected fingerprint information. Whether the detection area and the previous touch sequence (the fingerprint-related information that has been registered previously) are the same are used to generate the judgment result. And when the above judgment result is not the same, the detected fingerprint information, the detected area corresponding to the detected fingerprint information, and the touch timing sequence are stored in the database to generate new registered fingerprint information. On the contrary, if the above judgment result is the same, a warning signal is sent (step S4130), and step S410 is returned again.

Next, please refer to FIG. 5. FIG. 5 is a flowchart of an authentication procedure of the multiple fingerprint authentication method according to an embodiment of the present invention. In step S510, the authentication procedure is started. Then, the detected fingerprint information, the corresponding detection area, and the touch timing sequence input by the user are received, and the detected fingerprint information, the corresponding detection area, and the touch timing sequence are recorded in step S520 to obtain the input fingerprint information. During the execution of step S520, it can be determined whether the input time of the user's fingerprint input is greater than the preset input waiting time, and if the input time is greater than the input waiting time, the user's fingerprint input action can be ended.

After the user's fingerprint input action ends, step S530 is executed. In step S530, it is judged whether the input fingerprint information input by the user is the same as the registered fingerprint information. If the judgment result of step S530 is the same, the activation command corresponding to the registered fingerprint information is sent (step S540). Conversely, if the determination result of step S530 is not the same, it is deemed that the authentication has failed (step S550).

Please refer to FIG. 6. FIG. 6 is a schematic diagram of a multi-fingerprint authentication device according to an embodiment of the present invention.

Please refer to FIG. 7. FIG. 7 illustrates an application example of the multi-fingerprint authentication method of the present invention. In step S710, it is determined whether to log in the fingerprint authentication registration, and when the fingerprint authentication registration has been logged in, step S720 is executed. If you have not logged in and fingerprint authentication registration, directly end this process.

Step S720 determines whether a private application folder is set. Here, if the private application folder is to be encrypted (the judgment result of step S720 is YES), step S730 is executed to perform the setting action of the private application folder, and if the judgment result of step S720 is otherwise, step S730 is skipped. The setting action of step S730 can be performed according to the registration procedure of FIG. 4, and the registered fingerprint information corresponding to the access to the private application folder is generated.

In step S740, it is determined whether to set a private calendar. Here, if the private calendar is to be encrypted (the judgment result of step S740 is YES), step S750 is executed to perform the setting action of the private calendar, and if the judgment result of step S740 is otherwise, step S750 is skipped. The setting action of step S750 can be performed according to the registration procedure of FIG. 4, and the registered fingerprint information corresponding to the access to the private calendar is generated.

In step S760, it is determined whether to set a private application desktop. Here, if the private application desktop is to be encrypted (the judgment result of step S760 is YES), step S770 is executed to perform the setting action of the private application desktop, and if the judgment result of step S760 is otherwise, step S770 is skipped. The setting action of step S770 can be executed according to the registration procedure of FIG. 4, and the registered fingerprint information corresponding to access to the private application desktop is generated.
