Embodiment approach

[0070] In a possible implementation manner, each position number in the position number set of the position to be interfered has the same value after subtracting a preset value, where the preset value is an integer greater than 1 and less than Q, and Q is the total number in the control The number of positions, generally Q is an even number.

[0071] For example, the default value is 2, and the value of each position number in the position number set of the position to be interfered with is 0, then the position number set of the position to be interfered is {2,4,6,8...Q }, the value of each position number in the position number set of the position to be interfered is 1 after the remainder 2, then the position number set of the position to be interfered is {1,3,5,7...Q-1}.

[0072] In another possible implementation manner, each number in the position number set of the position to be interfered may also be randomly selected from an integer between 1 and Q, for example, the posi...

Abstract

The invention discloses a password protection method and device, and belongs to the technical field of information security. The method comprises the following steps: detecting that the cursor is located in a control for inputting a password, if it is determined that the position number of the position where the current cursor is located is located in a predetermined position number set of to-be-interfered positions, determining position information of a click simulation position after adding a received character to the position of the cursor, sending the position information to a currently used input method application, and triggering the input method application to determine characters for simulating click on a currently displayed input interface according to the position information; receiving character information sent by the input method application, controlling to not add the characters into the control, so that some characters are inserted in the password inputting process, theinserted characters are not added into the control for inputting the password, password character strings remembered by the third-party input method can be disrupted, normal password input is not influenced, and the safety of the terminal can be improved.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to a password protection method and device. Background technique [0002] At present, there are more and more types of terminals, such as mobile phones and iPads, and various terminals have become indispensable electronic products in people's daily life. [0003] Generally, third-party input methods are installed on the terminal, such as Sogou input method, Baidu input method, etc. These third-party input methods have a characteristic: they will record the strings frequently entered by users, and then as long as the user enters the first character, it will Automatically prompts the string that the user often enters starting with this character, see figure 1 , figure 1 After the user enters the first character in the password input control provided by the prior art, the third-party input method reminds the user to frequently input a character string beginning...
