Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following will describe in detail an implementation method of the present invention with reference to the accompanying drawings and embodiments, so that how to apply technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
Example one
According to an embodiment of the present invention, there is provided a screen unlocking method applied to an electronic terminal, as shown in fig. 1, the method including:
step S101, under an unlocking interface of an electronic terminal, displaying a preset password rule list after receiving a preset instruction; the preset password rule list comprises more than one preset password rule.
In this embodiment, the electronic terminal may be a computer, a mobile phone, or any other electronic terminal requiring password protection. The user can set an unlocking password and a password rule corresponding to the unlocking password in the electronic terminal in advance. The unlocking password can be a pure number password, or a pure letter password, or a password of a combination of numbers and letters, or a password of a combination of numbers, letters and special characters. When the unlocking password contains numbers and letters at the same time, the corresponding password rules are correspondingly set to be two, and the two password rules respectively correspond to the operation rules corresponding to the numbers and the operation rules corresponding to the letters. For example, when the user sets the unlocking password to 123abc, the password rule corresponding to the number and the password rule corresponding to the letter in the password need to be set at the same time, so as to obtain the unlocking character to be input through the set password rule subsequently.
Assuming that a password rule corresponding to a number set by a user is n +1, wherein n is the number in the unlocking password; and assuming that the password rule corresponding to the letter set by the user is 'case change', when the screen is unlocked, after the user selects the password rule, the unlocking character to be input is 234 ABC.
In this embodiment, a user may set different password rules based on the same unlocking password, for example, for the unlocking password 123abc, a digital password rule may also be set to be n-1, where n is a number in the unlocking password; the letter cipher rule may be set such that the letter is converted into the preceding letter or the succeeding letter, the preceding letter is designated as Z/Z when the letter is A/a, and the succeeding letter is designated as A/a when the letter is Z/Z. According to the password rule, when unlocking the screen, after the user selects the password rule, the unlocking character to be input is 012zab (when the letter rule is to change the letter to the letter before the letter), or 012bcd (when the letter rule is to change the letter to the letter after the letter).
In addition, other password rules may be set, for example, on the input keyboard, the lower character corresponding to each character in the unlocking password is used as the input unlocking character, or the multiple/half value of each numeric character in the unlocking password is calculated.
In this embodiment, the number of clicks may be further used as a trigger condition for unlocking the password. For example, for a numeric code, pressing a number several times may be arranged to trigger another number, e.g., pressing number 2 twice may trigger entering numeric code 3, or clicking numbers 2, 3 in sequence may trigger entering numeric code 9.
It should be noted that the above password rules are not exhaustive, and may be set by the user or freely selected by the system, and the category of the password rules is not limited herein.
A user may set or select multiple password rules at a time to cause the system to form a list of password rules. And under an unlocking interface of the electronic terminal, after receiving a preset instruction, displaying the password rule list to a user for the user to select the password rule. Of course, the user may set or select only one password rule in the system in the previous period, and at this time, only the one password rule is shown in the password rule list.
In this embodiment, the preset password rule list may be displayed in the following ways:
in the first mode, a preset password rule list is displayed when a preset input character input by a user is received under an unlocking interface of the electronic terminal.
The preset input characters can be set by the system in advance, and a user can input the preset input characters through an input mode such as a physical keyboard and a virtual keyboard to expand the password rule list. For example, the user may click on "+" 3 times in succession on the keyboard to expand the list of password rules.
In a second mode, if the electronic terminal comprises a plurality of different function response keys, displaying the preset password rule list when the first preset function response key is detected to be pressed under the unlocking interface of the electronic terminal.
The first preset function response key can be set in advance by the system, and when the electronic terminal is a mobile phone or a tablet computer, the volume key can be used as the first preset function response key. That is, under the unlock interface of the electronic terminal, the user may expand the password rule list by pressing the volume key.
Meanwhile, if the electronic terminal includes a plurality of different function response keys, the present embodiment may enter the unlocking interface of the electronic terminal in the following manner:
and when the fact that the second preset function response key is pressed is detected, starting and displaying an unlocking interface of the electronic terminal.
The second preset function response key can be set in advance by the system, and when the electronic terminal is a mobile phone or a tablet computer, the on-off key can be used as the second preset function response key. That is, under the unlocking interface of the electronic terminal, the user may enter the unlocking interface of the electronic terminal by pressing the switch key.
In a third mode, if the electronic terminal includes a touch screen and the unlocking interface is displayed on the touch screen, a list display icon can be set in the unlocking interface. And under an unlocking interface of the electronic terminal, when the list display icon is detected to be clicked, displaying a preset password rule list.
The electronic terminal comprising the touch screen can be a smart phone, a tablet personal computer and any other electronic equipment with the touch screen, when the electronic equipment is unlocked in an interface, the unlocking interface comprises a list display icon, and a user clicks the list display icon to expand the password rule list.
It should be noted that the above ways of displaying the password rule list are not exhaustive, and may be set in advance by the system, and the system may also set other password rule display ways, which is not limited in this embodiment.
Step S102, obtaining a current unlocking algorithm based on a preset password rule selected from a preset password rule list by a user;
in this embodiment, each password rule in the password rule list may be arranged from top to bottom in sequence, and in order to improve the security level, only "rule 1", "rule 2", and … … may be displayed without displaying a specific rule algorithm; of course, a specific rule algorithm may also be presented according to the previous setting of the user, for example, the presentation rule 1: "n-1, case-to-case", i.e., representing that each number in the unlocking password is reduced by 1, and each letter is case-to-case, to obtain the unlocking character. The current unlocking algorithm is the specific rule algorithm currently selected by the user.
It should be noted that, in the above display manner, when each password rule does not display a specific rule algorithm, a brief hint word may be displayed for each password rule to help the user to memorize the specific rule algorithm, and the brief hint word is set by the user, so as to reduce the memory burden of the user.
Further, the preset password rule corresponding to the current unlocking algorithm may be highlighted according to a preset display mode in the embodiment. For example, after the password rule list is expanded and before the user selects the password rule, the current default password rule is displayed in a highlight text mode; after the user selects the password rule, the password rule selected by the user is displayed in a highlight mode.
In order to further improve the security of the unlocking password, in this embodiment, after the user selects the password rule, the password rule list is automatically hidden. The user may expand the password rule list again in any of the ways described above in step S101.
Further, the password rule list can be randomly changed in the display sequence of the password rules in each display. Therefore, the risk that the user is peeped by others when selecting the password rule can be further avoided.
Step S103, receiving an unlocking character input by a user;
in this embodiment, the user may input the unlocking character through a physical keyboard or a virtual keyboard, or the like. If the electronic terminal is an electronic device with a touch screen, an unlocking keyboard is displayed simultaneously under an unlocking interface of the electronic device, the unlocking keyboard comprises preset characters, and the preset characters comprise common characters on an entity keyboard such as numbers, letters, punctuation marks, special characters and the like. Preferably, the user inputs the unlocking character through the unlocking keyboard, and the electronic device receives the unlocking character input by the user through the unlocking keyboard.
In order to further improve the security of the unlocking password, the method of this embodiment further includes: and when the unlocking keyboard is displayed each time, the position layout of the preset characters on the unlocking keyboard is randomly changed. Because the position layout of the characters on the unlocking keyboard is not fixed, when the user inputs the unlocking characters, even if the clicking position sequence is peeped, the unlocking characters cannot be leaked.
Step S104, judging whether the unlocking character is correct or not according to a preset unlocking password and a current unlocking algorithm;
specifically, the present embodiment may determine whether the unlocking character input by the user is correct in the following two ways:
the method comprises the steps that firstly, a current unlocking algorithm is adopted to operate a preset unlocking password, and an operated unlocking password is obtained; and when the unlocking character is the same as the calculated unlocking password, determining that the unlocking character is correct.
The unlocking characters input by the user are obtained after the user operates the unlocking password according to the password rule selected by the user, meanwhile, the electronic terminal can also operate the unlocking password preset in the system according to the password rule currently selected by the user, and when the operation result of the system is the same as the result input by the user, the unlocking characters input by the user are determined to be correct.
In the second mode, the preset inverse operation of the current unlocking algorithm is obtained based on the current unlocking algorithm; calculating the unlocking character by adopting the preset inverse operation of the current unlocking algorithm to obtain the calculated unlocking character; and when the calculated unlocking character is the same as the preset unlocking password, determining that the unlocking character is correct.
In this embodiment, each preset password rule has a preset inverse operation, that is, after the user selects one password rule, the electronic terminal system may obtain not only the current unlocking algorithm corresponding to the password rule, but also the inverse operation corresponding to the current unlocking algorithm based on the current unlocking algorithm. For example, if the current unlock algorithm is set to "n-1, case transition", then its corresponding inverse operation may be set to "n +1, case transition". The electronic terminal system adopts the inverse operation of the current unlocking algorithm to operate the unlocking character input by the user to obtain the operated unlocking character, then compares the operated unlocking character with an unlocking password preset in the electronic terminal by the user, and determines that the unlocking character input by the user is correct when the operated unlocking character and the unlocking password are the same.
And step S105, when the unlocking character is correct, executing unlocking operation.
In this embodiment, when the operation result of the system is different from the result input by the user, it is determined that the unlocking character input by the user is incorrect, and when the unlocking character is incorrect, the unlocking is not performed, and the user is prompted to input the unlocking character again.
In this embodiment, when the unlocking character is correct, after the unlocking operation is performed, the method further includes any one of the following items:
1. after receiving a change instruction, changing the existing password rule specified by the change instruction;
2. after receiving an adding instruction, adding a password rule input by a user in a preset password rule list;
3. and deleting the existing password rule specified by the deleting instruction after receiving the deleting instruction.
After the user successfully unlocks the screen and enters the electronic terminal, a certain password rule in the password rule list can be changed, added and deleted at any time, and correspondingly, after the electronic terminal receives a change instruction/an add instruction/a delete instruction of the user, the electronic terminal executes corresponding change/add/delete operation.
According to the screen unlocking method provided by the embodiment, the preset password rule list is displayed under the unlocking interface of the electronic terminal, so that a user can select one preset password rule from the preset password rule list, and further obtain the current unlocking algorithm. When a user unlocks the screen, the screen can be unlocked only by inputting a correct unlocking character obtained according to a preset unlocking password and a current unlocking algorithm. In the process, even if the unlocking character input by the user is peeped, the password cannot be leaked. Therefore, the technical scheme provided by the invention can effectively prevent the leakage of the password for unlocking the screen, and has higher safety. In addition, in the embodiment, as a plurality of password rules can be set, a user can randomly select one of the password rules when using the electronic terminal, so that the unlocking algorithm is not fixed when unlocking the screen, thereby further improving the security of unlocking the password and improving the security performance of the electronic terminal.
Example two
On the basis of the first embodiment, the second embodiment further provides a screen unlocking method, as shown in fig. 2, the method includes:
step S201, under an unlocking interface of the electronic terminal, displaying a preset password rule list after receiving a preset instruction; the preset password rule list comprises more than one preset password rule;
in this embodiment, the preset password rule list may be displayed in the following ways:
in the first mode, a preset password rule list is displayed when a preset character input by a user is received under an unlocking interface of the electronic terminal.
In a second mode, if the electronic terminal comprises a plurality of different function response keys, displaying the preset password rule list when the first preset function response key is detected to be pressed under the unlocking interface of the electronic terminal.
In a third mode, if the electronic terminal includes a touch screen and the unlocking interface is displayed on the touch screen, a list display icon can be set in the unlocking interface. And under an unlocking interface of the electronic terminal, when the list display icon is detected to be clicked, displaying a preset password rule list.
Step S202, obtaining a current unlocking algorithm based on a preset password rule selected from a preset password rule list by a user;
in this embodiment, the method further includes: and when the change times of the preset password rules are detected to exceed a first preset time threshold value in a first preset time period, locking the electronic terminal. That is, the system does not allow the user to change the password rule a plurality of times in a short time, and locks the electronic terminal when the user changes the password rule 3 times in 15s, for example. One purpose of this function is to prevent any change in the password rules after the electronic terminal is taken by another person, and when the system detects that the password rules are changed many times in a short time, it is considered that the user is not operating the electronic terminal.
Step S203, receiving an unlocking character input by a user;
preferably, the user inputs the unlocking character through an unlocking keyboard under the unlocking interface. In order to further improve the security of the unlocking password, the method of this embodiment further includes: and when the unlocking keyboard is displayed each time, the position layout of the preset characters on the unlocking keyboard is randomly changed.
Step S204, judging whether the unlocking character is correct or not according to a preset unlocking password and a current unlocking algorithm;
in step S205, when the unlock character is correct, an unlock operation is performed.
In this embodiment, the method further includes: and locking the electronic terminal when the error times of the unlocking characters are detected to exceed a second preset time threshold value in a second preset time period. That is, the system does not allow the user to input the wrong unlocking character multiple times in a short time, for example, to lock the electronic terminal when the user inputs the wrong unlocking character 4 times in 10 s. When the system receives wrong unlocking characters for multiple times in a short time, the user is not supposed to operate the electronic terminal at the moment.
The embodiment further adds a locking function on the basis of the first embodiment, thereby further improving the safety performance of the electronic terminal.
