[0051] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] The present invention provides an embodiment of a method for generating a random numeric keyboard, see Figure 1 The method for generating a random numeric keyboard specifically includes the following contents:

[0053] S101: receiving a password input instruction;

[0054] In this step, the received password input instruction may be an instruction sent by an external terminal to the terminal where the user is located, or an instruction generated by the terminal where the user is located. The password input instruction is used to indicate that the user of the terminal where the user is located needs to enter a password number.

[0055] S102: Divide the numeric keyboard into regions and determine a color code corresponding to each sub-region;

[0056] In this step, the numbers on the numeric keypad are divided into three areas. The number 123 is in area R (the color code is red), and at the 123 position on the original keyboard, the number is marked in red; the number 456 is in area G (the color code is green), and at the 456 position on the original keyboard, the number is marked in green; the number 7890 is in area B (the color code is blue), and at the 7890 position on the original keyboard, the number is marked in blue.

[0057] S103: Randomly sort the numbers in each word area;

[0058] In this step, the numbers in each area can only be randomly exchanged within the area.

[0059] S104: Generate a random numeric keyboard based on the color code corresponding to each sub-area and the order of the numbers in each word area.

[0060] In this step, two methods, namely, digital partitioning and color marking, are used to arrange and mark the numbers, which makes it easy to find the numbers and increases the input speed. It is easy for people with poor eyesight to input, reduces the difficulty of input, and ensures the security of the password.

[0061] From the above description, it can be seen that the method for generating a random numeric keyboard provided by the embodiment of the present invention receives an instruction to input a password; divides the numeric keyboard into regions and determines the color code corresponding to each sub-region; randomly sorts the numbers in each word region; and generates a random numeric keyboard based on the color code corresponding to each sub-region and the sorting of the numbers in each word region. The method can reduce the number of searches for numbers, thereby improving the efficiency of password input, reducing the risk of password leakage, and improving the security of transactions.

[0062] In one embodiment of the present invention, see Figure 2 After step S101 of the random number keyboard generation method, the following contents are specifically included:

[0063] S105: Determine the layout of the numeric keyboard of the current terminal;

[0064] S106: Determine the area division method of the numeric keyboard according to the layout method of the numeric keyboard.

[0065] Correspondingly, in step S102 , the numeric keyboard is divided into areas, including: dividing the numeric keyboard into areas based on the numeric keyboard area division method.

[0066] In this embodiment, different area division modes may be determined according to different layout modes of the numeric keypad of the current terminal (the terminal itself).

[0067] The layout modes in this embodiment include: nine-square grid and full keyboard;

[0068] Correspondingly, determining the area division method of the numeric keyboard according to the layout method of the numeric keyboard includes:

[0069] The layout mode of the numeric keyboard is a full keyboard, then the area division mode of the numeric keyboard is determined to be: a first area division mode;

[0070] If the layout of the numeric keyboard is a nine-square grid, then the area division method of the numeric keyboard is determined to be: the second area division method or the third area division method;

[0071] Among them, see Figure 3 , the first area is divided as follows: the first three keys of the numeric keypad (numbers 123) are the first sub-area, the middle three keys of the numeric keypad (numbers 456) are the second sub-area, and the last four keys of the numeric keypad (numbers 7890) are the third sub-area;

[0072] See also Figure 4, the second area is divided as follows: the first row of numeric keys (numbers 123) is the first sub-area, the second row of numeric keys (numbers 456) is the second sub-area, the third row of numeric keys (numbers 789) and the fourth row of numeric keys (number 0) are the third sub-area;

[0073] See also Figure 5 The third area is divided as follows: the first vertical row of numeric keys (number 147) is the first sub-area, the second vertical row of numeric keys (2580) is the second sub-area, and the third vertical row of numeric keys (number 369) is the third sub-area.

[0074] In this embodiment, see Figure 6 The specific implementation process of step S103 is as follows:

[0075] S1031: Determine a first number corresponding to any number key in the sub-area in a random manner;

[0076] S1032: Repeat execution: determine a second number corresponding to any one of the remaining number keys in the sub-area in a random manner, and the second number is not equal to the numbers corresponding to all the determined number keys.

[0077] In this embodiment, a random method is used to determine the numbers corresponding to the numeric keys in the sub-area. After the number corresponding to the first numeric key is determined, the numbers corresponding to the subsequent numeric keys (the second numeric key and the third numeric key) cannot be the same as the numbers corresponding to the previous numeric keys, thereby achieving random distribution of the numeric keys in the sub-area.

[0078] Take the first sub-area as an example:

[0079] The first number key in the first sub-area randomly generates a random number from 1 to 3, and the second number key randomly generates a random number from 1 to 3, but the random number generated by the second number key cannot be the same as the random number generated by the first number key. If they are the same, randomization needs to be performed again until the random number generated by the second number key is different from the random number generated by the first number key.

[0080] The third number key randomly generates a random number from 1 to 3, but the random number generated by the second number key cannot be the same as the random number generated by the first number key and the random number generated by the second number key, thereby achieving random distribution of number keys in the sub-area.

[0081] To further illustrate the present solution, the present invention provides a specific implementation method for randomly sorting the numbers in each word area in a method for generating a random numeric keyboard, which specifically includes the following contents:

[0082] The ten number keys are defined as R1, R2, R3, G1, G2, G3, B1, B2, B3, B4 respectively.

[0083] (1) Number random placement function PUTNUMER(), input: None; returns array Mynum

[10] and assigns it to R1-B4;

[0084]

[0085]

[0086] (2) Number acquisition function GETNUMER(inkey), input: keyboard position R1-B4; return represents the number putkey;

[0087]

[0088]

[0089] From the above description, it can be seen that the method for generating a random numeric keyboard provided by the embodiment of the present invention has the following beneficial effects:

[0090] 1. It is easy to find numbers and increases the input speed.

[0091] 2. It is easy for people with poor eyesight to input, reducing the difficulty of input.
