Description
Technical Field
The application relates to the technical field of terminals, in particular to a PIN code reinforced memory method and electronic equipment.
Background
A Subscriber Identity Module (SIM), also called SIM card, is an intelligent card mainly used for storing Subscriber Identity data, short message data and telephone numbers. After the SIM card is inserted into the electronic device, the electronic device can access a global system for mobile communication (GSM) and has communication capability.
The SIM card contains personal information of the user, and once the electronic equipment of the user is lost, the information in the SIM card is at risk of being stolen. In order to secure information of the SIM card, the current SIM card allows a user to set a Personal Identification Number (PIN), also called a PIN code, thereto. After the user sets the PIN code for the SIM card, the electronic device may require the user to enter the PIN code to authenticate the SIM card each time the SIM card is powered on. If the user enters the correct PIN code, the electronic device will normally load the SIM card to enable communication capabilities. If the user inputs wrong PIN codes or continuously inputs wrong PIN codes for a certain number of times, the electronic equipment locks the SIM card, and therefore protection of information of the SIM card is achieved.
At present, besides PIN codes, when a user uses an electronic device, many other password information, such as: a screen locking password, a login password of each application account, a payment password and the like. Because the number of the passwords is large, difficulty exists in memorizing and the passwords are easy to confuse, a user can easily forget the PIN code in a short time after setting or changing the PIN code, and the SIM card cannot be used on the electronic equipment for verification when the user powers on the SIM card next time, so that the electronic equipment cannot be used, and the user use experience is seriously influenced.
Disclosure of Invention
In order to help a user memorize a PIN code after the user sets or modifies the PIN code of a SIM card, the embodiment of the application provides a PIN code reinforced memorizing method and electronic equipment.
In a first aspect, an embodiment of the present application provides a method for strengthening memory of PIN codes, including: setting a PIN (personal identification number) of a SIM (subscriber identity module) card on electronic equipment, wherein the PIN has x characters, and the electronic equipment stores the PIN, and x is a positive integer greater than or equal to 1; on the nth day after the PIN is set by the user, the electronic equipment automatically sends the stored PIN to the SIM card module for verification without inputting the PIN, a screen locking password verification interface is displayed after verification is passed, a screen locking password input by the user on the screen locking password verification interface is obtained, a main interface of the electronic equipment is displayed after the screen locking password verification is passed, and n is a positive integer greater than or equal to 1; when the user is required to enter a PIN code: the electronic equipment prompts the PIN code according to a first rule, the first rule comprises that on the mth day after the user sets the PIN code, y characters in the PIN code are prompted to the user, m and y are positive integers larger than or equal to 1, n is not equal to m, k characters of the PIN code input by the user on an SIM card verification interface are obtained, k is larger than or equal to (x-y), the k characters of the PIN code input by the user on the SIM card verification interface are verified, if the verification is passed, a screen locking password verification interface is displayed, a screen locking password input by the user on the screen locking password verification interface is obtained, and after the screen locking password verification is passed, a main interface of the electronic equipment is displayed. In one implementation, the lock screen password verification interface may be a power-on password verification interface.
According to the technical scheme, after the user sets the PIN code, the electronic equipment prompts partial content of the PIN when the user inputs the PIN code, so that the user can remember the content of the PIN code, the PIN code is strengthened to memorize, and the situation that the electronic equipment cannot be used due to the fact that the user forgets the PIN code is avoided.
In one implementation, prompting the user for y characters in the PIN code includes: and displaying a SIM card verification interface when the SIM card is electrically loaded, wherein the SIM card verification interface comprises PIN code prompt information, and the PIN code prompt information comprises y characters of the PIN code. Therefore, when the user inputs the PIN code on the SIM card verification interface, the content of the PIN code is recalled according to the prompt information of the PIN code, and the PIN code is subjected to strengthened memory.
In one implementation, the user is prompted that the number of characters in the PIN remains the same or decreases as m increases. Therefore, after the user sets the PIN code, the electronic equipment can gradually increase the difficulty of recalling the PIN code along with the increase of the number of days m, so that the user can remember the PIN code under the condition of less prompt information, and the memory of the user on the PIN code is strengthened.
In one implementation, the first rule further includes: judging whether the user correctly inputs the PIN code at one time on the mth day after the PIN code is set; if the user correctly inputs the PIN code at one time, the number of characters in the PIN code prompted to the user on the m +1 th day after the PIN code is set by the user is smaller than the number of characters in the PIN code prompted to the user on the m th day after the PIN code is set by the user; if the user does not correctly input the PIN at one time, the number of characters in the PIN prompted to the user on the m +1 th day after the user sets the PIN is equal to the number of characters in the PIN prompted to the user on the m th day after the user sets the PIN. Therefore, the electronic equipment can determine whether the user can remember the PIN code according to the current prompt information according to whether the user correctly inputs the PIN code at one time, if yes, the difficulty of recalling the PIN code is improved, and if not, the difficulty of recalling the PIN code is kept unchanged.
In one implementation, the first rule further includes: if the user is prompted for 1 character in the PIN code on the mth day after the user sets the PIN code, and the user correctly inputs the PIN code at one time, the user is not prompted for any character in the PIN code on the m + k days after the user sets the PIN code, and k is a positive integer greater than 1. Thus, if the user can remember the PIN code under the condition of only prompting 1 character in the PIN code, the electronic equipment guides the user to input the PIN code completely by means of self memory under the condition of not prompting the PIN code within k days later so as to strengthen the memory of the user on the PIN code.
In one implementation, the first rule further includes: if the PIN codes are correctly input at one time in the m + 1-m + k days after the PIN codes are set by the user, the SIM card verification interface does not include PIN code prompt information from the m + k +1 days after the PIN codes are set by the user. In this way, if the user can input the PIN code completely by means of his own memory without prompting the PIN code for k days, the electronic device considers that the PIN code is memorized by the user, and therefore, the electronic device does not display PIN code prompting information on the SIM card verification interface after that.
In one implementation, the first rule further includes: judging whether the user correctly inputs the PIN code at one time on the Mth day after the PIN code is set, wherein M is the duration of a preset password reinforced memory period and is a positive integer; if the user correctly inputs the PIN code at one time, the SIM card verification interface does not comprise PIN code prompt information from the M +1 th day after the PIN code is set by the user; if the user does not input the PIN code correctly at one time, the password reinforced memory period is reset. Therefore, if the user does not correctly output the PIN code at one time on the Mth day after the PIN code is set, the electronic equipment considers that the user does not memorize the PIN code in the password reinforced memory period, and therefore the electronic equipment resets the password reinforced memory period to enable the user to carry out a round of reinforced memory.
In one implementation mode, the PIN prompt information further comprises a prompt switch, and the prompt switch responds to the click operation of a user to switch between an on state and an off state; when the prompting switch is in an on state, the PIN code prompting information displays at least one character of the PIN code according to a first rule; when the prompting switch is in an off state, the PIN prompting information shields all characters of the PIN. In this way, the electronic device allows the user to autonomously select whether to accept PIN code enhanced memory.
In one implementation, the prompt switch defaults to an off state, and when it is detected that the user has input an incorrect PIN code, the prompt switch switches to an on state. Therefore, when the user inputs the wrong PIN code, the electronic equipment starts the PIN code to strengthen the memory.
In one implementation mode, the PIN prompt information further comprises an unlocking switch, and the unlocking switch responds to the click operation of a user to switch between an on state and an off state; when the unlocking switch is in an on state, the PIN prompt information displays the complete content of the PIN; when the unlocking switch is in a closed state, the PIN prompt message displays at least one character of the PIN according to a first rule. In this way, the electronic device allows the user to actively view the complete contents of the PIN code when he forgets it.
In one implementation, the method further comprises: when the fact that a user clicks an unlocking switch in a closed state is detected, biological information of the user is obtained; determining whether the user is a target user according to the biological information; and if the user is the target user, the unlocking switch is switched to the on state. Therefore, the electronic equipment allows the user to firstly carry out identity verification according to the biological information when forgetting the PIN code, and actively check the complete content of the PIN code when the identity verification is passed.
In one implementation, the method further comprises: and when the unlocking switch is in a closed state, if the condition that the user inputs an old PIN code on the SIM card verification interface is detected, the unlocking switch is switched to an open state. Thus, the electronic device allows the user to actively view the complete content of the new PIN code by entering the old PIN code when the user forgets the PIN code.
In a second aspect, an embodiment of the present application further provides an electronic device, where the electronic device includes a processor, a memory, and a display screen; the memory stores program instructions that, when executed by the processor, cause the electronic device to perform the methods of the above-described aspects and their various implementations.
In a third aspect, embodiments of the present application further provide a computer-readable storage medium, in which instructions are stored, and when the instructions are executed on a computer, the computer is caused to execute the methods of the above aspects and their respective implementation manners.
In a fourth aspect, the present application further provides a computer program product containing instructions, which when run on a computer, causes the computer to perform the method of the above aspects and its various implementations.
In a fifth aspect, embodiments of the present application further provide a chip system, where the chip system includes a processor, and is configured to enable the electronic device to implement the functions recited in the foregoing aspects, for example, to generate or process information recited in the foregoing methods.

Detailed Description
A subscriber identity module, also called a SIM card, is an intelligent card that is mainly used to store subscriber identity data, short message data and telephone numbers.

The following provides an exemplary description of the steps of the PIN code enhanced memory method provided in the embodiments of the present application.
Fig. 3 is a flowchart of a method for strengthening memory of PIN codes according to an embodiment of the present disclosure. As shown in fig. 3, the PIN code strengthening memorizing method may include the following steps S101 to S102.
Step S101, setting a PIN code of a SIM card of the user identity module on the electronic equipment, wherein the PIN code has x characters, the electronic equipment stores the PIN code, and x is a positive integer greater than or equal to 1.
In the embodiment of the present application, the setting of the PIN code for the SIM card by the user may include setting the PIN code for the SIM card without setting the PIN code by the user to start the security verification for the SIM card, and further include modifying the PIN code when the user has set the PIN code for the SIM card before.
Illustratively, as shown in fig. 4, if the user wants to set a PIN code for a SIM card for which the PIN code is not set, the user may find a setting page 10 of the PIN code in a setting application of the electronic device, the setting page 10 may include a PIN code switch 11 of the SIM card, and if the user clicks 16 the PIN code switch 11, the electronic device may generate a PIN code setting window 12. The PIN code setting window 12 may include therein, for example, an input box 13, a determination button 14, and a cancel button 15. If the user wants to set a PIN code for the SIM card, the user can enter the content of the PIN code he wants to set in the entry box 13 and then click the confirmation button 14, wherein the PIN code is typically a string of digits, e.g. 4 digits, 6 digits, etc. Thus, the next time the SIM card is powered up, the electronic device may require the user to enter a PIN code to authenticate the SIM card. If the user gives up setting the PIN code for the SIM card, the cancel button 15 can be clicked to exit the PIN code setting window 12.
For example, as shown in fig. 5A and 5B, after the user sets a PIN code for the SIM card, the electronic device may add an option 21 of changing the PIN code of the SIM card to a setting page of the PIN code, and if the user clicks 22 the PIN code option 21 of the SIM card, the electronic device may generate the PIN code modification window 12. The PIN code modification window 12 may include therein, for example, an input box 13, a determination button 14, and a cancel button 15. The electronic device first prompts the user to enter the old PIN code in the PIN code modification window 12, at which point if the user wants to modify the PIN code of the SIM card, the old PIN code previously set may first be entered in the entry box 13 and then the confirmation button 14 is clicked 23. At this time, the electronic device verifies the old PIN code input by the user, and after the old PIN code is verified, the electronic device prompts the user to input a new PIN code in the PIN code modification window 12. At this time. The user may enter a new PIN code in the input box 13 and then click 24 the confirmation button 14 again. Thus, the next time the SIM card is powered up, the electronic device may require the user to enter a new PIN code to authenticate the SIM card. If the user gives up modifying the PIN code of the SIM card, the cancel button may be clicked to exit the PIN code setting window.
In the embodiment of the application, when the user sets or modifies the PIN code, the electronic device may record the specific content of the PIN code set by the user. In addition, the electronic device may also record the time when the user sets or modifies the PIN code, such as: the electronic device may record the day the user set the PIN code and the day the PIN code was modified, or the electronic device may record the precise time the user set or modified the PIN code, for example: XX month XX day XX of XX year.
And step S102, when the electronic equipment needs the user to input the PIN code, prompting the PIN code.
In order to enhance the memory of the PIN code by the user, after the PIN code is set or modified by the user, the electronic device may enter a PIN code enhanced memory period, which may last for several days from the time the PIN code is set or modified by the user. During the reinforced memory period of the PIN code, the electronic equipment can display PIN code prompt information to a user according to a certain rule when the user inputs the PIN code, for example, when the SIM is powered off and then powered on again, so as to prompt the PIN code and help the user to reinforce the memory of the PIN code.
In one implementation, when the electronic device needs a user to input a PIN code, the PIN code may be prompted according to a certain rule, for example, on the m-th day after the user sets the PIN code, y characters in the PIN code are prompted to the user, m and y are positive integers greater than or equal to 1, where n is not equal to m. Wherein the electronic device prompts the user that the y characters in the PIN code can be implemented in the form of a mask that can be implemented by the PIN code obscuring at least one character. The more characters in the mask that are masked, the fewer characters in the PIN code that are correspondingly prompted to the user; the fewer characters in the mask are masked, the more characters in the PIN code are correspondingly prompted to the user; when any character of the PIN code is shielded in the mask, the whole content of the PIN code is correspondingly prompted to a user; when the mask obscures all the characters of the PIN code, the correspondence does not prompt the user for any content of the PIN code.
For example, when the electronic device is restarted or turned on from a power-off state, the SIM card is loaded, and if the user sets a PIN code for the SIM card on the electronic device, the electronic device displays the SIM card verification interface 30 during the process of loading the SIM card, so as to request the user to input the PIN code for verification. As shown in fig. 6A, during the enhanced memory period of the PIN code, the SIM card verification interface 30 may include an on-screen keyboard 31 and a PIN code prompt message 32. The PIN code prompt message 32 may include a mask 33 of a specific length.
Illustratively, when the mask is formed by the PIN code masking any one character, if the PIN code is 654321, the mask may be 65432, or 6543, or 654, etc.; when the mask is formed by the PIN code masking any two characters, if the PIN code is 654321, the mask may be 65 × 32, or × 543 × 1, or 65 × 21, etc.; when the mask is formed by the PIN code masking any three characters, if the PIN code is 654 x, the mask may be 5 x 32, or 543 x 1, or 5 x 21, etc.; and so on.
In this way, the user can recall the complete content of the PIN code set before him, and enter the PIN code at the SIM card verification interface, according to the prompt of the mask. After the user inputs the PIN code, the electronic device may perform matching verification on the PIN code input by the user and the PIN code stored in the SIM card. If the matching is successful, the PIN code verification is passed, the electronic device successfully loads the SIM card, and the screen locking password verification interface 70 of the electronic device is entered as shown in fig. 6B. When the user completes unlocking operation in any one of modes of verifying a face, a fingerprint, a screen locking password and the like on a screen locking password verification interface, the electronic equipment enters a main screen interface of the operating system to complete a starting process.
In one implementation, the electronic device allows a user to verify a PIN code by entering k characters of the PIN code at a SIM card verification interface, where k is greater than or equal to (x-y).
For example, the electronic device may only require the user to enter the obscured character of the x characters of the PIN code, and the remaining characters may be automatically filled in by the electronic device for the user. For example, if the electronic device prompts the user for y characters in the PIN code, the number of characters in the PIN code that are obscured is (x-y), at which point the user need only enter (x-y) characters in the PIN code, i.e., k equals (x-y).
For example, the electronic device may allow the user to enter the PIN code by bit, and if the user completes entering all the masked character bits during the process of entering the PIN code, the electronic device may fill the user with the remaining unmasked character bits of the PIN code. For example: when the PIN code is "654321" and the mask that the electronic device prompts the user is "6 x 21", if the user enters "6543", the electronic device may automatically populate "21" for the user, at which time the number k of characters of the PIN code entered by the user at the SIM card authentication interface is greater than (x-y).
For example, the electronic device may require the user to enter all of the characters of the PIN code to initiate authentication. At this time, the number k of characters of the PIN code input by the user on the SIM card verification interface is greater than (x-y) and equal to x.
In one implementation, the electronic device may determine the duration of the PIN code strengthening memory period according to a certain rule.
Illustratively, the PIN code enhanced memory period may last for a fixed number of days, such as 7 days, 14 days, 21 days, or the like.
For example, the duration of the reinforced memory period of the PIN code can be determined according to the length of the PIN code, and the longer the length of the PIN code is, the longer the duration of the reinforced memory period of the PIN code is. For example: when the length of the PIN code is 4 characters, the duration of the reinforced memory period of the PIN code can be 7 days; when the length of the PIN code is 6 characters, the duration of the reinforced memory period of the PIN code can be 14 days; when the length of the PIN code is 8 characters, the duration of the PIN code reinforcement memory period may be 21 days.
For example, the duration of the PIN code strengthening memorizing period can be determined according to the memorizing degree of the PIN code of the user. For example, in a PIN code strengthened memory period of an initial duration, the electronic device may evaluate a degree of memory of the PIN code by the user, if the electronic device determines that the PIN code is completely memorized by the user, the electronic device may end the PIN code strengthened memory period in advance, and if the electronic device determines that the PIN code is not completely memorized by the user in the initial PIN code strengthened memory period, the electronic device may extend the PIN code strengthened memory period.
In one implementation, the electronic device may determine the number of masked characters of the mask in the PIN code prompt message according to a certain rule.
For example, the number of masked characters of the mask may increase as the number of times the SIM card is powered up increases.
For example, the number of masked characters of the mask may remain constant or gradually increase as the number of days between the current time and the time when the user sets or modifies the PIN code increases. For example, the electronic device may maintain a positive correlation of the number of masked characters for a mask to the number of days m, and determine the number of masked characters for the mask in the daily PIN hint from the correlation.
The following is an example of a variation of the number of masked characters of the mask, taking the PIN code reinforcement memory period duration M as 14 days.
Illustratively, as shown in fig. 7A, on day 1 of the reinforced memory period of the PIN code, the mask 33 includes the least number of masked characters, for example, only two masked characters may be included, and the difficulty of the user to recall the password is the lowest, so that the user can quickly recall the PIN code according to the PIN code to complete the first reinforced memory.
For example, as shown in fig. 7B, on day 2 of the reinforced memory period of the PIN code, the mask characters included in the mask 33 may be increased compared to day 1, for example, 3 mask characters may be included, at which time the difficulty of the user to recall the password is increased compared to day 1, but since the user has completed one reinforced memory on day 1, the user can easily recall the PIN code to complete the second reinforced memory even if the difficulty is increased.
For example, as shown in fig. 7C, on day 7 of the reinforced memory period of the PIN code, the masked characters included in the mask 33 may be increased compared to days 1 and 2, for example, 5 masked characters may be included, at which time the difficulty of the user to remember the password is further increased compared to the previous days, but since the user has completed multiple times of reinforced memory before, the user may easily recall the PIN code and complete the reinforced memory again.
For example, as shown in fig. 7D, on day 14 of the reinforced memory period of the PIN code, all characters in the mask 33 may be masked characters, and at this time, the user needs to input the PIN code by himself, since the user has completed a plurality of times of reinforced memory, the user can generally input a correct PIN code, if the user inputs an incorrect PIN code, it is indicated that the user does not memorize the PIN code, at this time, the rule may be reset, and a password reinforced memory process for day 14 may be restarted.
For example, as shown in fig. 7E, if the user inputs the correct PIN code on the 14 th day of the PIN code strengthening memorizing period, the PIN code strengthening memorizing period is ended, and after the user sets the PIN code for 14 days, the electronic device does not display the PIN code prompting message in the SIM card verification interface 30.
For example, the electronic device may increase the number of the mask characters in the mask every at least one day during the PIN code strengthening memory period, and the number of the mask characters in the mask may gradually increase for the same number of days m as the number of days increases. For example: on day 1 after the user sets the PIN code, 2 masked characters are included in the mask; in days 2-4 after the PIN code is set by the user, the mask comprises 3 shielding characters, and the position of at least one shielding character in the mask in each day is different; on 5th to 8 th days after the PIN code is set by the user, the mask comprises 4 shielding characters, and the position of at least one shielding character in the mask of each day is different; on 9 th to 13 th days after the PIN code is set by the user, the mask comprises 5 shielding characters, and the position of at least one shielding character in the mask of each day is different; on day 14 after the user sets the PIN code, all characters in the mask are masked characters.
For example, the electronic device may determine the number of the masked characters in the mask for the m +1 th day according to the number of the masked characters included by the mask on the m th day after the PIN is set by the user and whether the mask is correctly input by the user at one time during the reinforced memory period of the PIN. Specifically, if the user correctly inputs the mask at once on day m, the number of masked characters in the mask on day m +1 may be greater than the number of masked characters in the mask on day m, e.g., the number of masked characters in the mask on day m plus 1; if the user does not correctly input the mask at one time on day m, the number of masked characters in the mask for day m +1 may be the same as the number of masked characters in the mask for day m. For example, as shown in fig. 8A, if the mask contains 2 masked characters on the 1 st day after the user sets the PIN code and the user correctly inputs the mask at one time, as shown in fig. 8B, on the 2 nd day after the user sets the PIN code, the mask may contain 3 masked characters, and on the 2 nd day after the user sets the PIN code, if the user fails to correctly input the PIN code at one time on the 2 nd day after the user sets the PIN code, as shown in fig. 8C, on the 3 rd day after the user sets the PIN code, the mask still contains 3 masked characters.
Further, if the user correctly inputs the mask once a plurality of times during the reinforced memory period of the PIN code, the PIN code may appear in the form of prompting only 1 character on the mth day after the user sets the PIN code (for example, if the user correctly inputs the mask once for three consecutive days from the first day, the PIN code appears in the form of prompting only 1 character on the 4 th day after the user sets the PIN code when the mask has a length of 6 characters and the mask includes 2 masked characters on the 1 st day during the reinforced memory period of the PIN code). At this time, if the user correctly inputs the mask at one time also on the m-th day of the PIN code reinforcement memory period, the electronic device may display the mask in a manner of masking all characters for the next k days. If the user correctly inputs the PIN code at one time on the m + 1-m + k days after the PIN code is set, the electronic equipment does not display the PIN code prompt information on the SIM card verification interface from the m + k +1 days after the PIN code is set by the user, namely, the PIN code reinforced memory period is ended in advance.
In one implementation, the electronic device may determine the location of the masked characters of the mask according to certain rules. For example, the masked characters in the mask may be located in the first few bits of the mask; for another example, the masked characters in the mask may be located in the last few bits of the mask, and for another example, the masked characters in the mask may be located in selected bits of the mask; as another example, the location of the occluding character in the mask may be determined randomly; as another example, the positions of the occluding characters in the mask may alternate with the number of days. The change rule of the position of the masked character of the mask may be specified by a user or determined by the electronic device, which is not limited in this embodiment of the application.
In one implementation mode, the electronic equipment can automatically send the stored PIN code to the SIM card module for verification without inputting the PIN code by the user on the nth day after the PIN code is set by the user, a screen locking password verification interface is displayed after the verification is passed, a screen locking password input by the user on the screen locking password verification interface is acquired, a main interface of the electronic equipment is displayed after the screen locking password is verified, and n is a positive integer greater than or equal to 1.
For example, after the reinforced memory period of the PIN code is finished, the electronic device may further determine whether the user really remembers the PIN code, and if it is determined that the user really remembers the PIN code, the electronic device may help the user to automatically input the PIN code when the user needs to input the PIN code subsequently, so as to improve user experience.
For example, after the electronic device PIN code strengthening memory period is over, the electronic device may generate a SIM card verification interface including a screen keyboard and not including PIN code prompt information during loading of the SIM card. The user can input the PIN code under the condition that the PIN code prompt information does not exist, the electronic equipment verifies the PIN code input by the user, if the PIN code passes verification, the electronic equipment successfully loads the SIM card, enters a screen locking password verification interface of the electronic equipment, and records that the number of times that the user continuously and correctly inputs the PIN code under the condition that the PIN code prompt information does not exist is 1. During the subsequent z times of loading the SIM card by the electronic device, if the user can correctly enter the PIN code z times (z is greater than or equal to 1) in succession without the PIN code prompting information, the electronic device may determine that the user remembers the PIN code. Then, the electronic equipment can automatically input the PIN code for the user on the SIM card verification interface in the process of loading the SIM card for the z +1 th time, so that the electronic equipment can automatically complete SIM card loading, quickly jump to the screen locking password verification interface from the SIM card verification interface, and does not need the user to manually input the PIN code, thereby improving the user experience.
Optionally, if the electronic device determines that the user remembers the PIN code, the electronic device may not display the SIM card verification interface during the (n + 1) th loading of the SIM card, and the process of the electronic device automatically inputting the PIN code for the user may be performed in the background, so that this SIM card loading process is not perceived by the user. Therefore, the electronic equipment can directly enter the screen locking password verification interface after being started, the whole starting process is the same as the starting process when the PIN code is not set, and the user experience is further improved.
In one implementation, the electronic device may determine, according to a certain rule, a frequency of displaying the PIN code prompt information in the SIM card verification interface. For example, during the reinforced memory period of the PIN code, the electronic device may adjust the frequency of displaying the PIN code prompt information in the SIM card verification interface according to the number of days, for example, decrease the frequency of displaying the PIN code prompt information in the SIM card verification interface according to the number of days; for another example, in the reinforced memory period of the PIN code, the electronic device may determine, according to the frequency of the user using the electronic device, the frequency of displaying the PIN code prompt information in the SIM card verification interface, for example, the more frequently the user uses the electronic device, the higher the frequency of displaying the PIN code prompt information in the SIM card verification interface; for another example, in the reinforced memory period of the PIN code, when the electronic device may power on the SIM card for the previous time or several times, the PIN code prompt information is displayed in the SIM card verification interface.
For example, when the SIM card is powered on multiple times a day, the electronic device may display the PIN code prompt message in the SIM card verification interface only when the SIM card is powered on and loaded for the first time, and automatically fill the PIN code for the user when the SIM card is powered on and loaded for the subsequent time. For example, on the ith day of the enhanced memory period of the PIN code, after the user gets up in the morning, the electronic device is powered on, and the SIM card is powered on and loaded for the first time on the day; the electronic equipment can display PIN prompt information corresponding to the ith day on the SIM card verification interface, so that a user can complete a reinforced memory task of the current day; during the rest of the time after the day, if the electronic device powers up the SIM card again due to shutdown, restart, etc., the electronic device will automatically fill the PIN code for the user when the SIM card is powered up and loaded. Therefore, the frequency of inputting the PIN code by the user is reduced by the electronic equipment, so that the PIN code is input by the user on the electronic equipment at most once every day, and the use experience of the user is improved.
In one implementation, the electronic device may provide a privacy-free input switch in a setting application thereof, and the user may set a state of the privacy-free input switch by clicking or sliding the privacy-free input switch. When the password-free input switch is in an on state, the electronic equipment can automatically fill the PIN code for the user when the user is determined to remember the PIN code and the SIM card is loaded at the 2 nd time in a day and the subsequent power-on; when the password-free input switch is in an off state, the electronic equipment requires the user to manually input the PIN code whenever the user is required to input the PIN code to verify the SIM card.
Illustratively, as shown in fig. 9, the electronic device may provide a privacy-free input switch 41 on the PIN code setting page 10, which privacy-free input switch 41 may appear after the user sets the PIN code on the SIM card. Generally, since the user usually sets the PIN code on the SIM card for security purposes, such as preventing others from making a call using the electronic device, preventing others from stealing the user information in the SIM card, etc., the secret-free input switch 41 may default to the off state from security perspective, and the secret-free input switch may be turned on only after the user actively turns on the secret-free input switch.
In one implementation, during the PIN code enhanced memory period, the electronic device also allows the user to actively select whether to display a mask in the SIM card verification interface according to the rules. As shown in fig. 10A and 10B, in the SIM card authentication interface 30, the PIN code prompt information 32 includes a prompt switch 34 in addition to the mask 33. The prompting switch 34 may be a dynamic icon switch, and the user may adjust the state of the prompting switch 34 by clicking on the icon. For example: when the prompting switch is in an on state, the prompting switch is displayed as an open eye icon as shown in a figure A, and when a user clicks the eye icon, the prompting switch is switched to an off state as shown in a figure B; when the cue switch is in the off state, the cue switch is displayed as a closed eye icon as shown in fig. B, and when the user clicks the eye icon, the cue switch is switched to the on state as shown in fig. a.
Further, when the prompt switch is in the on state, as shown in fig. 10A, the electronic device may display a mask according to the rule. For example: on day 1 of the enhanced memory period of the PIN code, if the prompt switch is in an on state, the electronic device can display a mask containing 2 shielding characters; on day 2 of the PIN code reinforcement memory period, if the hint switch is on, the electronic device may display a mask that includes 3 masked characters. When the prompt switch is in the off state, as shown in fig. 10B, the electronic device displays the mask in such a manner as to obscure all characters, i.e., does not prompt the user for any contents of the PIN code.
In one implementation, the prompt switch may default to an off state, so that when the electronic device requires a user to input a PIN code, the user may input the PIN code completely by his own memory without a mask prompt. And if the user inputs the correct PIN code, the electronic equipment finishes loading the SIM card and enters a screen locking password verification interface of the operating system. If the user inputs the wrong PIN code, the electronic equipment automatically switches the prompt switch to the open state so as to display the mask according to the rule, prompt the user and help the user to remember the PIN code.
In one implementation, the prompt switch may be default to an on state, such that the electronic device displays a mask according to the rule to prompt the user each time the electronic device requires the user to input a PIN code. If the user forgets the PIN code, the PIN code can be recalled according to the prompting of the mask. If the user thinks that the user remembers the PIN code, the user does not need the mask prompting, and the user can click the prompting switch to switch the prompting switch to the closed state.
In one implementation, the electronic device may memorize a final state of the prompting switch on the ith day after the user sets the PIN code, and use the final state of the prompting switch on the ith day of the PIN code strengthening memorizing period as an initial state of the prompting switch on the (i + 1) th day of the PIN code strengthening memorizing period.
For example: on the 1 st day after the user sets the PIN code, the prompting switch is in a default closed state, if the user clicks the prompting switch or inputs an incorrect PIN code, the prompting switch is switched to an open state, and the final state of the prompting switch on the 1 st day after the user sets the PIN code is the open state. Therefore, on day 2 after the user sets the PIN code, the initial state of the reminder switch may be the on state.
For another example, on day 2 after the user sets the PIN code, the prompt switch is in a default on state, if the user thinks that the user already remembers the PIN code and does not need mask prompting, the user can click the prompt switch to switch the prompt switch to an off state, and then the final state of the prompt switch on day 2 after the user sets the PIN code is the off state. Therefore, on the 3 rd day after the user sets the PIN code, the initial state of the tip switch may be the off state.
In one implementation, during the enhanced memory period of the PIN code, the electronic device also allows the user to actively view the complete content of the PIN code. As shown in fig. 11A and 11B, in the SIM card authentication interface 30, the PIN code prompt message 32 includes an unlock switch 35 in addition to the mask 33. The unlock switch 35 may be a dynamic icon switch, and the user may adjust the state of the unlock switch 35 by clicking an icon or other means. For example: when the unlock switch 35 is in the on state, the unlock switch 35 is displayed as an unlocked lock icon as shown in fig. 11B, and when the user clicks the lock icon, the unlock switch 35 is switched to the off state; when the unlock switch 35 is in the off state, the unlock switch 35 is displayed as a locked cylinder icon as shown in fig. 11A, and when the user clicks the locked cylinder icon, the unlock switch 35 is switched to the on state. When the unlock switch 35 is in the on state, the electronic device may display the complete contents of the PIN code at the mask position. When the unlock switch 35 is in the on state, the electronic device may display a mask according to the rule and the state of the reminder switch. The unlock switch 35 defaults to the off state.
In one implementation, when the user clicks the unlock switch when the unlock switch is in the off state, the electronic device may perform biometric information verification on the user, and determine whether the user currently operating the electronic device is a target user, for example, an owner of the electronic device, according to a result of the biometric information verification, where the biometric information may be fingerprint information, face information, iris information, and the like. If the user who operates the electronic equipment is the owner of the electronic equipment, the electronic equipment switches the unlocking switch from the off state to the on state, and if the user who operates the electronic equipment is the owner of the electronic equipment, the electronic equipment keeps the unlocking switch in the off state. Therefore, the electronic equipment can only allow the owner to actively check the complete content of the PIN code in the reinforced memory period of the PIN code, and the PIN code is ensured not to be leaked.
For example, as shown in fig. 12A, when the user clicks 36 the unlock switch 35 with the unlock switch 35 in the off state, the electronic device may generate a fingerprint verification interface 50 as shown in fig. 12B on the upper layer of the SIM card verification interface 30, where the fingerprint verification interface 50 may include, for example, an element 51 for guiding the user to input fingerprint information, for example, a fingerprint pattern, and prompt text such as "verify fingerprint with light touch on the fingerprint sensing area below", and the like. Next, the electronic device may detect whether there is a pressing action of a finger of the user on the fingerprint identification module, and if the pressing action of the finger of the user is detected, the fingerprint identification module collects fingerprint information of the user. The electronic device can match the collected fingerprint information with fingerprint information input by the user in advance. If the collected fingerprint information is successfully matched with the fingerprint information input by the user in advance, the user biological information passes verification, the electronic device closes the fingerprint verification interface, and the unlocking switch 35 is switched to an on state as shown in fig. 12C, so that the complete content of the PIN code is displayed. If the matching between the collected fingerprint information and the fingerprint information previously input by the user fails, the verification of the biological information of the user fails, the electronic device closes the fingerprint verification interface, and the unlocking switch 35 is kept in a closed state.
The fingerprint identification module may be, for example, a fingerprint identification module disposed below the display screen (i.e., a fingerprint under the screen), a fingerprint identification module disposed on the back of the electronic device (i.e., a fingerprint on the back), a fingerprint identification module disposed on a frame of the electronic device (i.e., a fingerprint on the frame), or a fingerprint identification module disposed on the front of the electronic device, such as a fingerprint identification module disposed on a key of the main screen (e.g., a home key fingerprint).
For example, as shown in fig. 13A, when the user clicks 37 the unlock switch 35 in a state that the unlock switch 35 is turned off, the electronic device may generate a face verification interface 60 as shown in fig. 13B on an upper layer of the SIM card verification interface 30, and simultaneously turn on a face recognition module of the electronic device to collect face information of the user, and in the process of collecting the face information, the face verification interface 60 may display an interactive animation 61 that the face information is being collected. The electronic equipment can match the collected face information with face information input by the user in advance. If the collected face information is successfully matched with the face information input by the user in advance, the biological information of the user passes verification, the electronic equipment closes the face verification interface, and the unlocking switch 35 is switched to be in an on state, so that the complete content of the PIN code is displayed. If the matching between the collected face information and the face information input by the user in advance fails, the verification of the biological information of the user fails, the electronic device closes the face verification interface, and the unlocking switch 35 is kept in a closed state.
The face recognition module may include, for example, a front-facing camera, a floodlight, a dot-matrix projector, and/or an infrared camera, and may further turn on one or more of these components to acquire the face information of the user.
In one implementation, if the PIN code hardening memory period is opened after the user modifies the PIN code, the electronic device also allows the user to enter the old PIN code (the PIN code before modification) in the SIM card verification interface to view the new PIN code (i.e., the PIN code after modification). To achieve this, the electronic device may record the old PIN code when the user modifies the PIN code, so as to facilitate verification of the old PIN code entered by the user.
For example, as shown in fig. 14A, when the unlock switch 35 is in the off state, if the user clicks 38 the unlock switch 35, the electronic device may prompt the user to enter the old PIN code at the current SIM card verification interface 30. The electronic equipment matches the old PIN 39 input by the user with the old PIN recorded by the electronic equipment; if the matching is successful, the electronic device switches the unlock switch 35 to the on state as shown in fig. 14B to display the complete content of the new PIN code; if the matching is unsuccessful, the electronic device keeps the unlocking switch 35 in the off state, or the electronic device can guide the user to continue the biometric information verification and check the complete content of the PIN code in a biometric information verification mode.

The software programs and/or sets of instructions in the memory 602, when executed by the processor 603, cause the electronic device to carry out the method steps of: setting a PIN (personal identification number) of a SIM (subscriber identity module) card on electronic equipment, wherein the PIN has x characters, and the electronic equipment stores the PIN, and x is a positive integer greater than or equal to 1; on the nth day after the PIN is set by the user, the electronic equipment automatically sends the stored PIN to the SIM card module for verification without inputting the PIN, a screen locking password verification interface is displayed after verification is passed, a screen locking password input by the user on the screen locking password verification interface is obtained, a main interface of the electronic equipment is displayed after the screen locking password verification is passed, and n is a positive integer greater than or equal to 1; when the user is required to enter a PIN code: the electronic equipment prompts the PIN code according to a first rule, the first rule comprises that on the mth day after the user sets the PIN code, y characters in the PIN code are prompted to the user, m and y are positive integers larger than or equal to 1, n is not equal to m, k characters of the PIN code input by the user on an SIM card verification interface are obtained, k is larger than or equal to (x-y), the k characters of the PIN code input by the user on the SIM card verification interface are verified, if the verification is passed, a screen locking password verification interface is displayed, a screen locking password input by the user on the screen locking password verification interface is obtained, and after the screen locking password verification is passed, a main interface of the electronic equipment is displayed. According to the technical scheme, after the user sets the PIN code, the electronic equipment prompts partial content of the PIN when the user inputs the PIN code, so that the user can remember the content of the PIN code, the PIN code is strengthened to memorize, and the situation that the electronic equipment cannot be used due to the fact that the user forgets the PIN code is avoided.
In one implementation, the software program and/or the sets of instructions, when executed by the processor 603, cause the electronic device to implement the following method steps: and displaying a SIM card verification interface when the SIM card is electrically loaded, wherein the SIM card verification interface comprises PIN code prompt information, and the PIN code prompt information comprises y characters of the PIN code. Therefore, when the user inputs the PIN code on the SIM card verification interface, the content of the PIN code is recalled according to the prompt information of the PIN code, and the PIN code is subjected to strengthened memory.
In one implementation, the user is prompted that the number of characters in the PIN remains the same or decreases as m increases. Therefore, after the user sets the PIN code, the electronic equipment can gradually increase the difficulty of recalling the PIN code along with the increase of the number of days m, so that the user can remember the PIN code under the condition of less prompt information, and the memory of the user on the PIN code is strengthened.
In one implementation, the first rule further includes: judging whether the user correctly inputs the PIN code at one time on the mth day after the PIN code is set; if the user correctly inputs the PIN code at one time, the number of characters in the PIN code prompted to the user on the m +1 th day after the PIN code is set by the user is smaller than the number of characters in the PIN code prompted to the user on the m th day after the PIN code is set by the user; if the user does not correctly input the PIN at one time, the number of characters in the PIN prompted to the user on the m +1 th day after the user sets the PIN is equal to the number of characters in the PIN prompted to the user on the m th day after the user sets the PIN. Therefore, the electronic equipment can determine whether the user can remember the PIN code according to the current prompt information according to whether the user correctly inputs the PIN code at one time, if yes, the difficulty of recalling the PIN code is improved, and if not, the difficulty of recalling the PIN code is kept unchanged.

Thus, if the user can remember the PIN code under the condition of only prompting 1 character in the PIN code, the electronic equipment guides the user to input the PIN code completely by means of self memory under the condition of not prompting the PIN code within k days later so as to strengthen the memory of the user on the PIN code.
In one implementation, the first rule further includes: if the PIN codes are correctly input at one time in the m + 1-m + k days after the PIN codes are set by the user, the SIM card verification interface does not include PIN code prompt information from the m + k +1 days after the PIN codes are set by the user. In this way, if the user can input the PIN code completely by means of his own memory without prompting the PIN code for k days, the electronic device considers that the PIN code is memorized by the user, and therefore, the electronic device does not display PIN code prompting information on the SIM card verification interface after that.
In one implementation, the first rule further includes: judging whether the user correctly inputs the PIN code at one time on the Mth day after the PIN code is set, wherein M is the duration of a preset password reinforced memory period and is a positive integer; if the user correctly inputs the PIN code at one time, the SIM card verification interface does not comprise PIN code prompt information from the M +1 th day after the PIN code is set by the user; if the user does not input the PIN code correctly at one time, the password reinforced memory period is reset. Therefore, if the user does not correctly output the PIN code at one time on the Mth day after the PIN code is set, the electronic equipment considers that the user does not memorize the PIN code in the password reinforced memory period, and therefore the electronic equipment resets the password reinforced memory period to enable the user to carry out a round of reinforced memory.
In one implementation mode, the PIN prompt information further comprises a prompt switch, and the prompt switch responds to the click operation of a user to switch between an on state and an off state; when the prompting switch is in an on state, the PIN code prompting information displays at least one character of the PIN code according to a first rule; when the prompting switch is in an off state, the PIN prompting information shields all characters of the PIN. In this way, the electronic device allows the user to autonomously select whether to accept PIN code enhanced memory.
In one implementation, the prompt switch defaults to an off state, and when it is detected that the user has input an incorrect PIN code, the prompt switch switches to an on state. Therefore, when the user inputs the wrong PIN code, the electronic equipment starts the PIN code to strengthen the memory.
In one implementation mode, the PIN prompt information further comprises an unlocking switch, and the unlocking switch is switched between an on state and an off state in response to the clicking operation of a user; when the unlocking switch is in an on state, the PIN prompt information displays the complete content of the PIN; when the unlocking switch is in a closed state, the PIN prompt message displays at least one character of the PIN according to a first rule. In this way, the electronic device allows the user to actively view the complete contents of the PIN code when he forgets it.
In one implementation, the software program and/or the sets of instructions, when executed by the processor 603, cause the electronic device to further implement the method steps of: when the fact that a user clicks an unlocking switch in a closed state is detected, biological information of the user is obtained; determining whether the user is a target user according to the biological information; and if the user is the target user, the unlocking switch is switched to the on state. Therefore, the electronic equipment allows the user to firstly carry out identity verification according to the biological information when forgetting the PIN code, and actively check the complete content of the PIN code when the identity verification is passed. Thus, the electronic device allows the user to actively view the complete content of the new PIN code by entering the old PIN code when the user forgets the PIN code.
In one implementation, the software program and/or the sets of instructions, when executed by the processor 603, cause the electronic device to further implement the method steps of: and when the unlocking switch is in a closed state, if the condition that the user inputs an old PIN code on the SIM card verification interface is detected, the unlocking switch is switched to an open state.
