Based on the hardware structure, the embodiment of the password input method is provided.
Referring to fig. 2, fig. 2 is a flowchart illustrating a password input method according to a first embodiment of the present invention.
In a first embodiment, the password input method includes the steps of:
step S10, the mobile terminal responds to a password input request triggered by a user, acquires a keyboard to be displayed in a preset storage area according to the password input request, and extracts a key sequence in the keyboard to be displayed;
it should be noted that the mobile terminal may be a mobile phone, a tablet, and other mobile devices, and may also be a security device for inputting a password in other departments, which is not limited in this embodiment.
The password input request of the user can be a password input request triggered by the user on the current display interface, for example, the user unlocks through a mobile phone, and also can be an operation of paying the password when the user enters the payment interface, the password input request of the user comprises the input request of the user, for example, the type of the password display interface required to be selected by the user, for example, when the user carries out the operation of paying the password through the payment interface, the user can obtain that the user only needs to input the bank card password, and the general bank password is a 6-digit password displayed, and under the condition, a relatively complex letter keyboard with letter display does not need to be displayed, so that the complexity of inputting the password by the user is caused.
In the specific implementation, the information required to be input by the user, such as the payment password that the user only needs to input the bank card password, is obtained in the password request of the user through the password input request of the user, and in this case, the numeric keyboard only needs to be displayed for corresponding display, so that the complexity of user input is reduced, and the user experience is improved.
Step S20, randomly arranging the key sequences in the keyboard to be displayed to obtain a random keyboard, and displaying the random keyboard;
it should be noted that the preset storage area may be a nonvolatile memory of a mobile phone, and a plurality of keyboard information, such as numeric keyboard information, alphabetic keyboard information, and symbol keyboard information, is stored in the preset storage area.
And acquiring keyboard information to be displayed in a preset storage area according to the password input request, for example, when a user performs a wakeup operation and performs an unlocking operation, acquiring correct password information stored by the user in the preset storage area, extracting password attributes in the password information, for example, only numbers in the password information are represented, and acquiring corresponding numerical keyboard information.
In a specific implementation, after the corresponding numeric keypad information is obtained, original numeric keypad information including a numeric sequence may be obtained, the original numeric keypad information may be pre-stored keyboard information used last time, and may also be pre-made numeric keypad information, keyboard information to be displayed is obtained in a preset storage area, and the corresponding keyboard sequence is obtained from the keyboard information.
In a specific implementation, the obtained keyboard sequence is randomly arranged, where the random arrangement may be random number generated, and the keyboard sequence is randomly arranged by the random number, or may be randomly arranged by other manners, which is not limited in this embodiment.
It will be appreciated that the rearranged keyboard sequences are recombined by a certain rule to generate a corresponding random keyboard, for example, the keyboard sequences are arranged correspondingly on twelve numeric keyboards, so that there is a random keyboard composed of twelve numbers and special characters. And pushing the generated random keyboard to a user, and enabling the user to input a corresponding password through the random keyboard.
Referring to fig. 3a, fig. 3b and fig. 3c, a conventional keyboard is a fixed-format keyboard, such as a numeric keyboard with numeric keypads arranged in order of size from 1 to 9, an alphabetic keyboard with a fixed arrangement consistent with a conventional keyboard, and a symbol keyboard with two parts, a numeric input part and a symbol input part, which are also arranged in a fixed arrangement.
As shown in fig. 4a, fig. 4b, and fig. 4c, the keyboard structure of the present invention is schematically illustrated, in the figure, the numeric keyboards are not displayed in a random arrangement manner from large to small, and the corresponding keyboard formats are generated in the alphabetic keyboard and the character keyboard in a random manner, instead of the existing fixed manner, and the keyboard is displayed in a random manner, so that the original fixed keyboard format improves the security of password input.
Step S30, responding to a click command input by a user based on the random keyboard, and determining coordinate information corresponding to the click command;
and receiving coordinate information input by a user through the random keyboard, searching a key-in value corresponding to the coordinate information in a locally pre-stored relation mapping table according to the coordinate information, verifying the key-in value, and hiding the random keyboard after the verification is successful.
And step S40, searching the keying-in value corresponding to the coordinate information in a local pre-stored relation mapping table according to the coordinate information, and taking the found keying-in value as a password.
In the embodiment, a mobile terminal responds to a password input request triggered by a user, acquires a keyboard to be displayed in a preset storage area according to the password input request, and extracts a key sequence in the keyboard to be displayed; randomly arranging the key sequences in the keyboard to be displayed to obtain a random keyboard, and displaying the random keyboard; responding to a click command input by a user based on the random keyboard, and determining coordinate information corresponding to the click command; and searching a key-in value corresponding to the coordinate information in a relation mapping table prestored locally according to the coordinate information, and taking the searched key-in value as a password. According to the invention, each time the user inputs the password, the random keyboard is pushed to display the password to the user for inputting the password, so that the password input safety is improved.
Further, as shown in fig. 5, a second embodiment of the password input method of the present invention is proposed based on the first embodiment, and in this embodiment, the step S10 specifically includes:
step S101, the mobile terminal responds to a password input request triggered by a user, extracts a keyboard type in the password input request, searches a keyboard to be displayed in a preset storage area according to the keyboard type, and extracts a key sequence in the keyboard to be displayed.
It should be noted that the keyboard information to be displayed includes at least one item of numeric keyboard information, alphabetic keyboard information, and symbolic keyboard information, that is, the keyboard type in the user password input request is extracted, and according to the keyboard type, corresponding keyboard information can be searched from a preset storage area, for example, when a user inputs a bank card password, display information of the bank card password currently displayed by the user is obtained, and a related password display type can be found through the display information, and through an attribute of the bank card password, the user can know that the user needs to use a numeric keyboard, so that the related numeric keyboard information is found in the keyboard information, and the user can perform password input through a simple keyboard more favorably.
In the specific implementation, a user inputs related account information on a display page, in this case, password information pre-stored in a mobile phone by the user can be acquired, judgment is performed according to the password information, it is judged that the password information of the user contains alphabetic information, an alphabetic keyboard can be extracted from a preset storage area through the acquired alphabetic information, and an extracted keyboard sequence of the alphabetic keyboard is acquired, so that the input requirement of the user can be met.
In this embodiment, the keyboard type in the password input request is extracted, the keyboard information to be displayed is searched in the preset storage area according to the keyboard type, the keyboard sequence in the keyboard information is extracted, the input requirement of the user is judged, and the related keyboard is obtained according to the judgment result, so that the input requirement of the user can be met, and the user experience is improved.
Further, as shown in fig. 6, a third embodiment of the password input method of the present invention is proposed based on the first embodiment and the second embodiment, in this embodiment, based on the first embodiment, the step S20 specifically includes:
step S201, calling a random function to enable the random function to traverse keyboard elements in a keyboard to be displayed, selecting target elements according to a preset probability, selecting reference elements related to the target elements through the target elements, combining the target elements and the reference elements to obtain a random keyboard, and displaying the random keyboard.
It should be noted that a random program is pre-stored in a preset storage area, the order of the keyboard can be disordered through the random program, the random program can be a section of random program in the bottom layer of the mobile phone software, the random program can be simply realized by modifying the software of the bottom layer of the mobile phone, the order of the keyboard can be disordered, if a user has other requirements on the random keyboard, the random program can be simply modified through the bottom layer of the software, and therefore the requirements of the user can be simply met by modifying the bottom layer of the software.
And acquiring the arranged keyboard sequence, recombining the arranged keyboard sequence into a random keyboard, and displaying the random keyboard.
It can be understood that after the keyboard sequence is disordered, the disordered keyboard sequence is recombined to generate a random keyboard, the random keyboard is correspondingly displayed, and the generated random keyboard is pushed to a user.
In the concrete implementation, in the process of inputting by the user, under the condition that an input error possibly exists, under the condition, the user can delete the input content with the input error, so that after deletion, no input content exists on the input interface of the user, the current keyboard is hidden, and a new random keyboard is generated to cover the current random keyboard, so that the situation that the user performs misoperation is ensured, the new random keyboard can be displayed, and the password input safety of the user is favorably improved.
Further, the step S201 specifically includes:
step S202, a random function is called through a preset interface, so that the random function traverses keyboard elements in a keyboard to be displayed, a target element is selected according to a preset probability, a reference element related to the target element is selected through the target element, the target element and the reference element are combined, a random keyboard is obtained, and the random keyboard is displayed.
In this embodiment, in the process of generating the random keyboard, a random program may be called through a preset interface, and the keyboard sequence is randomly arranged through the random program.
In the embodiment, the keyboard sequence is disordered through the random program, and the disordered keyboard sequence is recombined into a new random keyboard, so that the displayed keyboards are different and randomly generated when the user inputs the passwords at each time, and the password input safety of the user is ensured.
Further, as shown in fig. 7, a fourth embodiment of the password input method according to the present invention is proposed based on the first embodiment and the second embodiment, and in this embodiment, the method includes, before step S40:
step S401, associating the key-in value with the coordinate information, establishing a relational mapping table according to the associated key-in value and the coordinate information, and storing the relational mapping table locally.
It should be noted that the relation mapping table may be a mapping table in which a position relation between coordinate information and a random keyboard is stored, and the relation mapping table is stored locally, for example, a user confirms typing in a third input cell on the displayed random keyboard, the typing information of the user is determined, and an input value of the third input cell is found to be 6 in a relation mapping table pre-stored locally, so that the typing value of the user can be obtained.
It can be understood that the relation mapping table may be modified correspondingly to be consistent with the changed keyboard sequence relation under the condition of random scrambling through a random program, or may be established as a new relation mapping table under the condition of random scrambling through a random program, and the relation mapping table covers the original relation mapping table correspondingly to ensure the accuracy of the relation mapping table.
In this embodiment, the accuracy of the relational mapping table is ensured by establishing the relational mapping table of the random keyboard and the coordinate information and locally storing the relational mapping table.
Further, as shown in fig. 8, a fifth embodiment of the password input method according to the present invention is proposed based on the first embodiment and the second embodiment, in this embodiment, the description is made based on the first embodiment, and after step S40, the method further includes:
step S402, when the verification fails, the key sequences in the keyboard to be displayed are rearranged randomly to obtain a random keyboard, and the random keyboard is displayed.
It should be noted that, the coordinate information input by the user through the random keyboard is received, the keyed-in value corresponding to the coordinate information is searched in a relation mapping table pre-stored locally according to the coordinate information, the keyed-in value is verified, and the program for generating the random keyboard is re-executed under the condition that the verification fails, so that the user is ensured to display different random keyboards during each input.
Further, after the step S402, the method further includes:
step S403, counting the times of verification failure, and locking the current display interface when the times reach a preset time threshold.
It can be understood that, when the user inputs the password, the security of the password input of the user can be improved by displaying the random keyboard, but the user cannot input the password in an unlimited amount, in this case, the number of times of inputting the user can be limited, when the number reaches a preset number threshold, the interface used by the current user is locked, for example, the mobile phone sets the maximum number of input errors to be 5, and the user locks the interface currently input by the user after 5 times or under the condition of verification errors.
In the specific implementation, the preset time can be set after the user inputs a mistake once, and the random keyboard is pushed after the preset time is reached, so that the situation that the user repeatedly inputs wrong passwords is prevented, and the input accuracy of the user is improved.
In the embodiment, the current display interface is locked when the times of verification failure reaches the preset times threshold value through counting the times of verification failure, so that the situation that a user repeatedly inputs wrong passwords is prevented, and the input accuracy of the user is improved.
