Detailed Description
In order to make the objects, technical solutions and effects of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, the method for controlling the keypad security input of the mobile terminal according to the present invention includes the following steps:
s10, numbering positions of all characters on the virtual keyboard of the mobile terminal;
in the embodiment of the invention, the numbering of the positions of all characters on the virtual keyboard is not repeated and is started from zero continuously; for example, the virtual keyboard includes twenty-six virtual keys a, B, C, … …, and Z, and the keys are numbered with number a corresponding to number 0, B corresponding to number 1, C corresponding to number 2, … …, and Z corresponding to number 25, or they may be numbered in a disorderly sequence, for example, a corresponding to number 1, B corresponding to number 2, C corresponding to number 3, … …, Y corresponding to number 25, and Z corresponding to number 0.
A, B, C … … Z above refers to the touch screen area where the specific key is located, and does not mean the specific character.
In this embodiment, the step of numbering the positions of all the characters on the virtual keyboard further includes: predefining a character corresponding to each touch area on a virtual keyboard on a touch screen of the mobile terminal, and numbering each touch area;
each touch area is a rectangle, and the touch area is determined by coordinates of the lower left corner and the upper right corner of the rectangle; let the coordinates of the lower left corner and the upper right corner of the rectangle be (x1, x2), (y1, y2), respectively, then when there is a touch coordinate (x, y), if x1< x < y1 and x2< y < y2 are satisfied, the touch point touches the touch area of the rectangle, that is, touches the character corresponding to the touch area of the rectangle.
S20, generating a random number when detecting that the password is input through the virtual keypad of the touch screen in the mobile terminal.
In the embodiment of the invention, when detecting that the password is input through the virtual keyboard of the touch screen in the mobile terminal, a random number is generated; the number is a positive integer greater than or equal to zero.
And S30, adding the generated random numbers to the numbers corresponding to the characters to obtain new codes corresponding to the characters.
In the embodiment of the present invention, the generated random number is added to the number corresponding to each character to obtain a new code corresponding to each character, for example: the number corresponding to the original character is K, the generated random number is H, and the new code corresponding to the character is K + H.
And S40, performing remainder operation on the characters of the virtual keyboard by each new code to generate a final code, and filling each character into the virtual keyboard according to the corresponding final code.
In the embodiment of the present invention, the operation of adding each new code to the number of characters of the virtual keyboard to generate a final code, and filling each character into the virtual keyboard according to the corresponding final code includes:
the number corresponding to the original character is K, the generated random number is H, the new code corresponding to the character is K + H, and the K + H is virtualized.
In the embodiment of the present invention, an example that "the number corresponding to the original character is K, the generated random number is H, and the new code corresponding to the character is K + H" is described, for example: for example, if the number K =4 corresponding to the character D, and the random number generated this time is H =101, then K + H =105, and then in the virtual keyboard display this time, 105 takes 1 to 26 (26 characters in total), that is, D is displayed on the bit corresponding to 1.
An illustrative example is that the random number generated this time on a standard QWERTY keyboard is 101, and the character D will be displayed on the bits of the character a. As another example, character F would be displayed on the bits of character C. The displayed positions of each character on the virtual keyboard are different, so that the input safety is ensured.
In the invention, the main role of numbering the positions of all characters on the virtual keyboard is as follows: for the following mathematical calculations. And then dynamically adjusting the positions of the characters according to the calculation result to ensure that the displayed positions of the characters on the virtual keyboard are different each time, thereby ensuring the input safety. Especially, when the touch screen data of the mobile phone is acquired by others, the user can not know each virtual keyboard input.
In step S20, the effect of generating "random numbers" is to make the displayed bits of each character on the virtual keyboard different, so as to ensure the security of input. Especially, when the touch screen data of the mobile phone is acquired by others, the user can not know each virtual keyboard input.
Has the advantages that: the displayed positions of each character on the virtual keyboard are different, so that the input safety is ensured. Especially, when the touch screen data of the mobile phone is acquired by others, the user can not know each virtual keyboard input.
