The memory 220 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, various application programs, and the like; the storage data area may store data created according to the use of the terminal device 200, and the like. Further, the memory 220 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device, among others.

The input unit 240 may include a touch panel 241 and other input devices 242, wherein the touch panel 241, also referred to as a touch screen, may collect touch operations by a user on or near the touch panel 241 (such as operations by a user on or near the touch panel 241 using any suitable object or accessory such as a finger, a stylus, etc.). Specifically, the touch panel 241 may detect a touch operation of a user, detect signals caused by the touch operation, convert the signals into touch point coordinates, transmit the touch point coordinates to the processor 220, receive a command transmitted from the processor 220, and execute the command. In addition, the touch panel 241 may be implemented by various types, such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. Other input devices 242 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, power on/off keys, etc.), a trackball, a mouse, a joystick, and the like.

Of course, the terminal 200 may also include other components such as an earphone, a camera, an audio circuit, a speaker, etc., which are not shown in fig. 2 and will not be described in detail herein, according to the requirements of a specific application.

Referring to fig. 3, fig. 3 is a flowchart of a password protection method provided in the present application, and in the following description, taking the application of the method to the terminal 200 shown in fig. 2 as an example, a specific implementation flow of the method is as follows:

s301: a cursor is detected in a control for entering a password.

S302: judging whether the position number of the position of the current cursor is in a position number set of a predetermined position to be interfered, if so, entering S303; otherwise, S306 is entered.

In a possible implementation manner, the position numbers in the position number set of the positions to be interfered have the same value after a preset value is left, wherein the preset value is an integer larger than 1 and smaller than Q, Q is the total number of positions in the control, and generally Q is an even number.

For example, if the preset value is 2, the values obtained by subtracting 2 from the position numbers in the position number set of the positions to be interfered are all 0, the position number set of the positions to be interfered is {2,4,6,8 … … Q }, the values obtained by subtracting 2 from the position numbers in the position number set of the positions to be interfered are all 1, and the position number set of the positions to be interfered is {1,3,5,7 … … Q-1 }.

In another possible implementation, each number in the position number set of the to-be-interfered position may also be randomly selected from integers between 1 and Q, for example, the position number set of the to-be-interfered position is {1,2,4,5 … … Q-1}, or {1,2,3 }.

S303: after adding the received one character to the position where the cursor is located, position information simulating the click position is determined.

In specific implementation, after a terminal detects that a user clicks a certain position on a screen, the position information of the position can be sent to an input method application, the input method application determines a character clicked on a current input interface by the user according to the position information, sends the character to the terminal, and adds the character to a control for inputting a password by the terminal, so that the input of one character is completed.

In one possible embodiment, the position information of the simulated click position may be determined from position information added to the click position of the character at the position of the cursor.

For example, if the coordinates of the click position added to the character at the position of the cursor are (x, y) and the interval between two adjacent characters is (Δ x, Δ y), then (x + Δ x, y) may be used as the coordinate information of the simulated click position, and (x- Δ x, y) may also be used as the coordinate information of the simulated click position.

For another example, when the origin of coordinates is located on the long side of the terminal screen, the ordinate of the click position of the character added to the position where the cursor is located may be determined as the ordinate of the simulated click position; if the abscissa of the click position of the character added to the position of the cursor is determined to be greater than or equal to half of the width W of the terminal screen, determining the abscissa of the simulated click position according to the abscissa, for example, determining one M of the abscissa as the abscissa of the simulated click position, wherein M is an integer greater than 1; if it is determined that the abscissa of the click position of the character added to the position of the cursor is smaller than half the width W of the terminal screen, the abscissa of the simulated click position may be determined according to the abscissa and the width W of the terminal screen, for example, one-N part of the sum of the abscissa and the width of the terminal screen is determined as the abscissa of the simulated click position, where N is an integer greater than 1.

Specifically, referring to fig. 4, fig. 4 is a schematic diagram of determining position information of a simulated click position according to position information of a click position of a character added to a control according to an embodiment of the present application, where an origin of coordinates is located at an upper left vertex of a terminal screen, and assuming that the coordinate information of the click position of the character added to a position where a cursor is located is (x, y), if x < W, the coordinate of the simulated click position may be (x + (W-x)/2, y); if x > W/2, the coordinates of the simulated click position may be (x/2, y), wherein if the abscissa x/2, x + (W-x)/2 of the simulated click position is exactly between two character keys, the abscissa x/2 may be shifted to the right by a predetermined number of pixels, e.g., 5 pixels, to ensure that one character can be fetched.

Continuing with FIG. 4, if the character entered at a certain time is q, the coordinate of the click position of q is (x1, y1), since x1< W, the coordinate of the simulated click position is (x1+ (W-x1)/2, y1), if the character entered at a certain time is k, the coordinate of the click position of k is (x2, y2), since x2> W/2, the coordinate of the simulated click position is (x2/2, y 2).

Generally, the characters that can be used as the password are letters, numbers and underlines, so some characters can be selected from the characters to form a target character set, and then the character to be clicked is selected from the target character set, so in one possible implementation, the position information of the simulated click position is also determined according to the following steps: selecting a character from the target character set, and determining the position information of the click position corresponding to the selected character according to the corresponding relation between the stored character and the position information of the click position, wherein each character in the target character set meets the set requirement of being used as the password character in the control.

S304: and sending the position information to the input method application which is currently used, and triggering the input method application to determine the character which is simulated to be clicked on the input interface which is currently displayed according to the position information.

In specific implementation, the input method application cannot sense whether the terminal screen is clicked, and can determine the character clicked by the user only according to the position information of the click position sent by the terminal.

S305: and receiving information of characters simulating clicks, sent by the input method application, and controlling not to add the characters into the control.

In specific implementation, the character of the simulated click is used for disturbing the password information memorized by the input method application and is not contained in the password characters set by the user, so that the character of the simulated click sent by the received input method application can be controlled not to be added into the control, the normal password input of the user cannot be influenced, and the user experience is better.

S306: adding the received character to the position of the cursor.

Subsequently, if a password submission request is received, all characters in the control are submitted.

The above process is described below with reference to specific embodiments.

Assuming that the total number of positions of the control for inputting the lock screen password is 8, the position numbers are position 1, position 2 … … and position 8 from left to right, the position number set of the predetermined positions to be interfered is {1,3,5, 7}, and the lock screen password set by the user is assumed to be "qwe 147".

In a specific implementation, when the cursor is located in the control for inputting the password, the cursor is located at position 1 first, and position 1 is located in the position number set {1,3,5, 7} of the to-be-interfered position, then the terminal may determine position information of the simulated click position after adding a character "q" of the received user input to position 1 of the cursor, where the coordinate information of the click position of "q" is (x1, y1) and x1< W, and therefore, the coordinate information of the simulated click position is (x1+ (W-x1)/2, y1), and then the terminal may transmit the coordinate information (x1+ (W-x1)/2, y1) to the currently used input method application, trigger the input method application to determine the character simulated click on the currently displayed input interface according to (x1+ (W-x1)/2, y1), the character is sent to the terminal, the terminal controls not to add the character to the control after receiving the character, and if the character at (x1+ (W-x1)/2, y1) is 'y', the third-party input method remembers 'qy'.

Further, the cursor moves to the position 2 in the control, and the position 2 is not located in the position number set {1,3,5, 7} of the position to be interfered, so the terminal only needs to add the character "w" of the received user input to the position 2 where the cursor is located, and at this time, the third-party input method remembers "qyw".

Further, the cursor moves to the position 3 in the control, the position 3 is located in the position number set {1,3,5, 7} of the position to be interfered, at this time, after adding the received character "e" to the position 3 where the cursor is located, the terminal re-determines the position information of the simulated click position, wherein the coordinate information of the click position of "e" is (x3, y3), x3< W, and therefore, the coordinate information of the simulated click position is (x3+ (W-x3)/2, y3), sends the coordinate information (x3+ (W-x3)/2, y3) to the currently used input method application, triggers the input method application to determine the character simulated click on the currently displayed input interface according to (x3+ (W-x3)/2, y3), sends the character to the terminal, and the terminal controls not to add the character to the control after receiving the character, assuming that the character at (x3+ (W-x3)/2, y3) is "u", then the third-party input method remembers "qyweu".

Further, the cursor moves to the position 4 in the control, the position 4 is not located in the position number set {1,3,5, 7} of the position to be interfered, the terminal only needs to add the received character "1" input by the user to the position 4 where the cursor is located, and at this time, the third-party input method remembers "qyweu 1".

Further, the cursor moves to the position 5 in the control, the position 5 is located in the position number set {1,3,5, 7} of the position to be interfered, representing that the terminal needs to re-determine the position information of the simulated click position after adding the received character "4" to the position 5 where the cursor is located, wherein the coordinate information of the click position of "4" is (x4, y4), x4< W, and therefore, the coordinate information of the simulated click position is (x4+ (W-x4)/2, y4), then the terminal sends the coordinate information (x4+ (W-x4)/2, y4) to the currently used input method application, the triggering input method application determines the character simulated click on the currently displayed input interface according to (x4+ (W-x4)/2, y4), sends the character to the terminal, and the terminal controls not to add the character to the control after receiving the character, assuming that the character at (x4+ (W-x4)/2, y4) is "6", then the third-party input method remembers "qyweu 146".

Further, the cursor moves to a position 6 in the control, the position 6 is not located in the position number set {1,3,5, 7} of the position to be interfered, the terminal only needs to add one character "7" of the received user input to the position 6 where the cursor is located, and at this time, the third-party input method remembers "qyweu 1467".

By this time, the user completes the input of the screen-locking password, and through the process, the third-party input method eventually remembers the character string "qyweu 1467", and then, once the initial character "q" input by the user is detected, the third-party input method prompts "qyweu 1467", as shown in fig. 5.

According to the method and the device, the password memorized by the third-party input method can be inserted into some characters, so that the correct character string related to the user password cannot be prompted by the third-party input method, and related operations cannot be performed naturally, and therefore the safety of the terminal can be improved.
