The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Please refer to FIG. 1 , which is a schematic diagram of a module of the unlocking device 10 according to an embodiment of the present invention. In this embodiment, the unlocking device 10 can be applied to an electronic device having a touch screen, such as a mobile phone, a music player, a PDA, or a tablet computer, for the user to unlock the electronic device and perform subsequent operations by operating the touch screen, for example, After unlocking, use the electronic device to perform operations such as dialing or music playback. In this embodiment, the unlocking device 10 includes a storage module 100, an operation module 200, a processing module 300, and a control module 400.

The storage module 100 is configured to store data and related programs and the like required for realizing the normal operation of the electronic device, and corresponding data required to implement the unlocking operation of the electronic device. The data required to unlock the operation includes unlocking the information base. In some embodiments, the unlocking information library has at least one unlocking issue. In various embodiments, the unlocking question can be expressed in different forms. In some embodiments, the unlocking question can be expressed in the form of a simple arithmetic problem or a judgment question. For example, the unlocking question can be "1+2=?" or "1+3=4 is correct?" and the like. In some embodiments, unlocking information There are also answer options in the library. The answer option includes a correct item and an incorrect item, wherein the correct item corresponds to the correct answer information of each unlocking problem and is related to the corresponding unlocking problem, that is, between each unlocking problem and the corresponding information corresponding to the correct item. They are related to each other. When the unlocking problem is determined, the corresponding correct item is also determined and can be obtained. The information corresponding to the incorrect item may be any information other than the correct answer information of each unlocking question. For example, the storage module 100 can store two unlocking questions and four answering options, wherein the two answering options are the correct items associated with the two unlocking questions, and the other two answering options are respectively incorrect items, which are incorrect. The information corresponding to the item may be any other predetermined information such as predetermined text information or digital information. The information type of the incorrect item may be the same or different from the information type of the correct item. There are still four answer options stored in the storage module 100, which are the correct items of the two unlocking problems, and the other two are the incorrect items. In the case where the two correct items are text information, one of them is non- The information type of the correct item can be text, and the information type of another incorrect item can be a number, or the information type of two incorrect items can be text or number.

It will be appreciated that in some embodiments, the user may also define an answer option according to his or her own preferences. For example, in the case where the same unlocking question is set to "1+3=4 is correct?", the user can set the correct item associated with the problem to be "error" or "X" and define the incorrect item as "undefined" "Wait.

It will be appreciated that in other embodiments, the number of unlocking questions and answer options may vary to meet the needs of the customer.

The operation module 200 is coupled to the storage module 100, configured to detect whether the unlock button is pressed and to extract an unlocking question from the storage module 100 for display when the unlock button is pressed. The processing module 300 is connected to the operation module 200, and is configured to acquire an unlocking answer corresponding to the unlocking problem input by the user on the unlocking interface, and determine whether the unlocking answer is correct, and if yes, determine that the unlocking is successful and unlock the electronic device.

As shown in FIG. 2, in some embodiments, the operation module 200 includes a first detection unit 210, an extraction unit 220, and a display unit 230. The first detecting unit 210 is connected to the unlock button and is set to It is detected whether the unlock button is pressed and generated when the detection button is pressed and the extraction signal is output. The extracting unit 220 is connected to the first detecting unit 210 and the storage module 100, and is configured to receive the extracted signal output from the first detecting unit 210 and extract at least one unlocking problem from the storage module 100 after receiving the extracted signal. Since each unlocking problem is associated with the corresponding correct item, after the unlocking problem is extracted, the correct item corresponding to the unlocking problem can be determined through the association relationship. The display unit 230 is connected to the extraction unit 220, and is configured to receive the unlocking question extracted by the extraction unit 220 and display the extracted unlocking question on the unlocking interface.

In some embodiments, the user inputting an action to unlock the answer may be one of selecting the extracted answer options on the unlock interface. In these embodiments, after receiving the extraction signal, the extracting unit 220 may acquire the correct item according to the association relationship between the unlocking problem and the correct answer, and extract the correct item, in addition to extracting the unlocking problem from the storage module 100. come out. Moreover, the extracting unit 220 can simultaneously extract the same incorrect type of information as the correct item. For example, if the extracted unlocking problem is "1+2=?", the extracting unit 220 extracts the same digital type from the storage module 100 after extracting the correct item "3" of the question according to the association relationship. Incorrect items such as "4", "5" or "6". Or, if the extracted unlocking question is "1+3=4 is correct?", the extracting unit 220 extracts the same incorrect item such as "error" or "unsure" after extracting the correct item "correct". "Wait. In these embodiments, the display unit 230 displays the unlocking question, the correct item, and the incorrect item on the unlocking interface after receiving the unlocking question, the correct item, and the incorrect item extracted by the extracting unit 220.

It should be noted that, in these embodiments, the extracting unit 220 may extract the unlocking problem and the incorrect item from the storage module 100 by means of random extraction. Specifically, when the extracting unit 220 receives the extracted signal from the first detecting unit 210, a specific algorithm is executed. For example, in some embodiments, an unlocking problem may be randomly extracted from the storage module 100 using a shuffling algorithm. Then, after extracting the correct item of the unlocking problem, the extracting unit 220 uses the shuffling algorithm to extract the incorrect item from the unlocking information base in the storage module 100. It should be noted that, in these embodiments, the display unit 230 may be further configured to generate icons corresponding to the extracted unlocking questions and answer options respectively before displaying the extracted unlocking questions and answer options on the unlocking interface, for using the unlocking interface. Forming a first display area and a second display area, and respectively displaying an icon corresponding to the unlocking problem and an icon of the answer option in the first display area and the second display area for the user to touch the selection answer option, thereby enabling the user to A clearer understanding of the unlock process. For example, in the case where the extracted unlocking problem is "1+3=?", the correct item is "4", and the incorrect item is "5", the display unit 230 will generate three icons, one of which corresponds to the unlocking problem. "1+3=?", one icon corresponds to the correct item "4", and the other icon corresponds to the incorrect item "5".

In these embodiments, after the unlock question and answer option is displayed on the unlock interface, the processing module 300 obtains the unlock answer entered by the user on the unlock interface by obtaining an answer option selected by the user. Specifically, as shown in FIG. 3, the processing module 300 includes a second detecting unit 310, an obtaining unit 320, a comparing unit 330, and an unlocking unit 340. The second detecting unit 310 is arranged to detect whether any of the answer options are selected within the predetermined time interval, and if so, output an acknowledgment signal. The acquisition unit 320 is coupled to the second detection unit 310, configured to receive the confirmation signal and further obtain location information of the selected answer option. The comparing unit 330 is connected to the obtaining unit 320, and is configured to receive the location information of the selected answer option acquired by the obtaining unit 320, and compare the location information with the location information of the correct item of the extracted unlocking problem on the unlocking interface, And outputting the first detection signal when the determination is consistent, otherwise outputting the second detection signal.

It can be understood that, in some other embodiments, the user inputting an unlocking answer on the unlocking interface may also input relevant information by the user by handwriting. In these embodiments, the extraction unit 220 extracts only the unlocking question from the storage module 100 upon receiving the extracted signal, and transmits the extracted unlocking question to the display unit 230 for display. In this process, since the unlocking problem and its correct answer information are related to each other, when the unlocking problem is extracted, the corresponding correct answer information is correspondingly determined and available. The display unit 230 simultaneously forms an unlocking area for the user to input the relevant information by hand after displaying the unlocking problem. So, the user can The related information is entered in the unlocked area by a touch pen or a finger or the like to unlock the electronic device. In these embodiments, the second detecting unit 310 obtains the information input by the user in the unlocking area, and determines whether the information input by the user matches the correct answer information of the extracted unlocking question, and if yes, outputs the first detection. Signal, otherwise output the second detection signal. The unlocking unit 340 is connected to the second detecting unit 310, and is configured to receive the first detecting signal output by the second detecting unit 310 and perform an unlocking operation on the electronic device according to the first detecting signal, so that the user can perform the electronic device on the electronic device. Follow-up actions.

The control module 400 is coupled to the storage module 100, the operation module 200, and the processing module 300, and is configured to perform a corresponding operation when an unlock answer input by the user is incorrect. As shown in FIG. 4, the control module 400 can include a marking unit 410, a counting unit 420, and a determining unit 430. The marking unit 410 is connected to the second detecting unit 310 and the storage module 100, and is configured to receive the second detection signal output by the second detecting unit 310 and search for the currently extracted unlocking problem from the storage module 100 according to the second detecting signal. And after finding the corresponding information, it is marked and the flag signal is output. Counting unit 420 is coupled to marking unit 410 and is arranged to receive the marking signal and accumulate count 1. The determining unit 430 is connected to the marking unit 410 and the extracting unit 220, and is set to determine in real time whether the count accumulated by the counting unit 420 has reached a predetermined value. When it is determined that the count accumulated in the counting unit 420 has reached a predetermined value, the determining unit 430 Determining that the user has failed to unlock and issuing an end command to close the unlocking interface, and when it is determined that the count accumulated in the counting unit 420 has not reached the predetermined value, the determining unit 430 outputs a control signal to the extracting unit 220, and thus the extracting unit 220 is thus from the storage module 100. The extraction in the unmarked unlocking problem is extracted and sent to the display unit 230 for display after being extracted to the correct item and the incorrect item in the above manner.

The unlocking device 10 provided by the present invention unlocks an electronic device by operating the touch screen by displaying an unlocking problem on the unlocking interface and requiring the user to input an unlocking answer corresponding to the unlocking problem on the unlocking interface, and the unlocking problem is caused by the user operating the touch screen. The answer can be defined or selected by the user, so the outsider cannot easily unlock without knowing the unlock answer defined by the user. Electronic devices have improved the safety of the use of electronic devices. Moreover, since the control module 400 marks the current unlocking problem and randomly extracts other unlocking problems when the unlocking answer input by the user is wrong, it is possible to avoid the occurrence of repeated unlocking problems. Thus, even if the user forgets the correct item of one of the unlocking problems, the electronic device can be unlocked by answering the unlocking question that occurs later without being able to unlock the electronic device due to forgetting the correct item of the unlocking problem.

The present invention further provides an unlocking method for unlocking an electronic device equipped with the touch screen by operating a touch screen. Referring to FIG. 5, which is a flowchart of an unlocking method in an embodiment of the present invention, the unlocking method includes the following steps:

In step S100, the unlock information library is preset. In some embodiments, the unlocking information library includes at least one unlocking issue. The unlocking question can be a simple arithmetic problem or a judgment question. For example, can it be "1+2=?" or "1+3=4 is correct?"

In step S200, it is detected whether the unlock button is pressed, and if pressed, the unlocking problem is extracted from the unlocking information library and displayed. In some embodiments, the electronic device can be provided with an unlock button, and the user can initiate the unlocking operation by pressing the unlock button. When the unlock button is pressed, the unlocking question is extracted from the preset unlocking information library and sent to the unlocking interface for display.

It will be appreciated that in some embodiments, an unlocking problem may be randomly extracted from the above-described unlocking information base by employing an algorithm such as a shuffling algorithm.

In step S300, the unlocking answer input by the user on the unlocking interface is obtained and it is determined whether the unlocking answer is correct, and if so, it is determined that the unlocking is successful and the electronic device is unlocked. In different embodiments, the action of inputting the unlock answer may be different. For example, in some embodiments, the action of inputting the unlock answer may be that the user inputs any information on the unlock interface, and acquires the unlock entered by the user on the unlock interface. The answer can be realized by obtaining information input by the user on the unlocking interface, and detecting whether the unlocking action is correct or not by comparing whether the information input by the user is consistent with the answer of the preset extracted unlocking question. In other embodiments, enter the answer to unlock the answer. The action may select one of the multiple answer options displayed on the unlock interface. In this case, obtaining the unlock answer input by the user on the unlock interface may be implemented by obtaining an answer option selected by the user, and passing It is judged whether the answer option selected by the user is the correct item of the extracted unlocking question to detect whether the unlocking answer input by the user is correct or not.

The unlocking method of the present invention will be further described in detail below through a specific application embodiment. In the specific embodiment, the user inputting the unlocking answer is to select the correct answer option in the unlocking interface. As shown in FIG. 6, the unlocking method includes:

In step S11, an unlocking information library having an unlocking question and an answer option is set in advance. In this embodiment, the unlocking information database has at least one unlocking question and at least one answer option, and the at least one answering option includes at least the correct item of each unlocking question. The correct item corresponds to the correct answer information for each unlocking question and is related to each unlocking problem. That is, each unlocking problem is associated with the corresponding correct item. When the unlocking problem is determined, the corresponding correct item and the correct answer information of the unlocking problem corresponding to the correct item are also determined and can be obtained. . In some embodiments, the at least one answer option also includes an incorrect item. For example, when there are two unlocking problems preset, there are four answer options preset, two of which are correct items associated with the two unlocking questions, and the other two answering options are incorrect. item. The information corresponding to the incorrect item may be any predetermined text information or digital information, and the like. The information type of the incorrect item may be the same or different from the information type of the correct item. For example, if there are two correct items and two incorrect items in the four answer options in the answer option library, if one of the information types of the two correct items is text information, one of the incorrect items may be set. The information type is text, and the information type of another incorrect item is a number. Alternatively, you can set the information type of two incorrect items to text or number.

It can be understood that in some embodiments, the above unlocking question and answer options can be formed by the user and stored in the unlocking information base. Of course, in this case, the answer options can be set according to the user's preferences. For example, in the same setting, the unlocking question is "1+3=4 is it correct?" In the case, the user can set the correct item associated with the unlocking problem to be "Error" or "X", and set the incorrect item to "Uncertain" and so on.

In step S12, it is judged whether or not the unlock button is pressed, and if yes, the process proceeds to step S13, otherwise, the process returns to step S12 to continue determining whether the unlock button has been pressed. When the user wants to unlock the electronic device, the unlocking operation can be started by pressing the unlock button.

In step S13, an unlocking question and an answer option including at least the extracted correct item of the unlocking question are extracted from the unlocking information base. Since the unlocking problem is related to its correct item, after a certain unlocking problem is extracted, the correct item of the unlocking problem is also extracted. At the same time, in this embodiment, the incorrect items in the answer option library can also be extracted. The information type of the extracted incorrect item can be the same as the information type of the correct item. For example, if the extracted unlocking problem is "1+2=?", the correct item "3" of the question is extracted in association, and the incorrect item of the same type as the correct item is "4". ", "5" or "6" was also extracted. Or, if the extracted unlocking question is "1+3=4 is correct?", after the corresponding correct item "correct" is extracted in association, the corresponding text information such as "error" or "unsure" is also corresponding. The incorrect items were also extracted.

It will be appreciated that in some embodiments, an unlocking problem or an incorrect term may be randomly extracted from the above-described unlocking information base by employing an algorithm such as a shuffling algorithm.

In step S14, the extracted unlocking question and the extracted answer option are displayed on the unlocking interface. In some embodiments, before the extracted unlocking question and answer option are displayed on the unlocking interface, icons respectively corresponding to the extracted unlocking question and answer option may be generated, and the first display area and the first display area may be formed on the unlocking interface. The display area is displayed in the first display area and the second display area for the user to touch the selection answer option, so that the user can understand the unlocking process more clearly. For example, in the extracted unlock The problem is "1+3=?", if the correct item is "4" and the incorrect item is "5", three icons can be generated, one of which corresponds to the unlocking problem "1+3=?", one The icon corresponds to the correct item "4", and the other icon corresponds to the incorrect item "5", and the icon corresponding to the unlocking problem is displayed in the first unlocking area, and the icon corresponding to the correct item and the incorrect item is displayed in the first Second unlocked area.

In step S15, it is judged whether any of the answer options are selected, and if so, the process proceeds to step S17, otherwise, the process proceeds to step S16. In some embodiments, it is possible to detect which of the icons is selected by the user by detecting the coordinates of the point at which the capacitance/resistance in the second display area on the unlocking interface changes, and comparing the coordinates with the coordinates of each icon. It will be appreciated that the predetermined time interval can be set by the user.

In step S16, it is judged whether or not the predetermined time interval has been reached, and if it has been reached, the process goes to step S20, otherwise it returns to step S15 to continue to determine whether any of the answer options are selected. In some embodiments, the predetermined value may be automatically set by the system or set by the user according to his or her own needs.

In step S17, it is judged whether the selected answer option is the correct item of the extracted unlocking problem, and if so, the process goes to step S21, otherwise, the process goes to step S18. In some embodiments, it may be determined whether the selected answer option is by comparing the obtained location information of the selected answer option with the location information of the correct item of the extracted unlocking question on the unlocking interface. Extract the correct item for the unlock issue.

In step S18, the currently extracted unlocking problem is marked and cumulatively counted. When it is detected that the selected answer option is not the correct item of the extracted unlocking question, the current touch question is marked and the flag signal is outputted and then accumulated.

In step S19, it is judged whether or not the cumulative count has reached a predetermined value, and if yes, the process proceeds to step S20, otherwise, the process returns to step S13. In some embodiments, the predetermined value may be set automatically by the system or set by the user according to his or her own needs. In some embodiments, when it is determined that the accumulated count reaches a predetermined value, if the user has selected the incorrect item to reach the cumulative 5 times, it is determined that the unlocking operation fails and the unlocking interface is closed. When the cumulative count has not reached the predetermined value, then return to step S13 from Unlock other unlocking issues with unmarked in the repository. In the same way, other unlocking problems can also be extracted by random extraction.

In step S20, it is determined that the user has failed to unlock, and the unlocking interface is closed.

In step S21, it is determined that the user unlocking operation is successful, and the electronic device is unlocked.

The unlocking method provided by the present invention, by displaying an unlocking problem on the unlocking interface and requiring the user to input an unlocking answer corresponding to the unlocking problem on the unlocking interface, enables the user to unlock the electronic device by operating the touch screen, and, due to unlocking the answer and unlocking The problem corresponds, therefore, the outsider cannot easily unlock the electronic device without knowing the unlock answer defined by the user, thereby improving the security of the use of the electronic device. In addition, the unlocking method provided by the present invention can also extract other unlocking problems in the case that the correct item of the unlocking problem selected by the user is wrong, and the repetition of the unlocking problem may be avoided. Thus, even if the user forgets the correct item of one of the unlocking problems, the electronic device can be unlocked by answering the unlocking problem that occurs subsequently without being able to unlock the electronic device because the correct item of the unlocking problem is forgotten.
