Problems solved by technology

The more advanced the encoding technology for passwords, such as new digital certificates and bio-encryption technology, the more complicated it is to crack
People generally enter passwords through the physical keyboard provided by the network, but with the emergence of hackers, there are many Trojan horse programs similar to "keyloggers" that can easily steal the transaction passwords entered by users. Once the user's computer is infected with "keyloggers" "Trojan horse virus, the network system is planted with a "hook". The hacker monitors and records the user's keystrokes on the physical keyboard through the "hook" program, and can record the password entered by the user and send it to the hacker.

Embodiment 1

[0042] see figure 1 , the embodiment of the present invention provides a method for inputting a password, the method comprising:

[0043] Step 101: Control the movement of the card button on the screen, the password characters are displayed on the card button, the number of card buttons is N, and N is an integer greater than 1;

[0044] Step 102: Receive the input information that the user clicks the card button, and send the input information to the display box.

[0045] In the method provided by the embodiment of the present invention, by controlling the card button displaying the password characters, the card button can be moved arbitrarily on the screen, and the Trojan horse cannot capture the click position of the user, so it will not correspond the click position with the password characters, and obtain incorrect information. To the password characters entered by the user, the security of the password input by the user is improved.

Embodiment 2

[0047] see figure 2 , the embodiment of the present invention provides a method for inputting a password, the method comprising:

[0048] Step 201: There are card buttons on the screen, and password characters are displayed on each card button, and there are one or more card buttons;

[0049] Wherein, the embodiment of the present invention changes the static soft keyboard into a dynamic soft keyboard, such as image 3 As shown, there are several fluttering card buttons on the screen, one or more can be set, the specific number is not limited in the present invention, and a password character or a group of password characters can be displayed on each card button.

[0050]Specifically, in the embodiment of the present invention, the pixel points of the screen are used to indicate the position of the card button on the screen, the horizontal length of the screen is set to be LenX pixels, the vertical length is LenY pixels, and the lower left corner of the screen is used as the...

Embodiment 3

[0095] see Figure 7 , the embodiment of the present invention provides a password input device, the device includes: a control module 301, a receiving module 302 and a sending module 303, the receiving module 302 is connected to the control module 301 and the sending module 303;

[0096] Wherein, the control module 301 is used to control the movement of the card button on the screen, the password character is displayed on the card button, the number of the card button is N, and N is an integer greater than 1;

[0097] A receiving module 302, configured to receive input information that the user clicks the card button;

[0098] The sending module 303 is configured to send the input information received by the receiving module to the display box.

[0099] The device provided by the embodiment of the present invention moves arbitrarily on the screen through the card button displaying the password characters, and its moving direction changes randomly, and there are no rules to f...

Abstract

The invention discloses a method and a device for inputting a password and belongs to the field of computer security. The method comprises the following steps of: controlling N card buttons to move on a screen, wherein password characters are displayed on the card buttons and N represents an integer larger than 1; and receiving input information when a user clicks the card buttons and transmitting the input formation to a display frame. The device comprises a control module, a receiving module and a transmitting module. According to the method and device for inputting the password in the invention, the card buttons displaying the password characters move randomly on the screen and the movement directions are random and disordered, so that Trojan can not capture the clicking positions of the user, thus Trojan can not correspond to the clicking positions with the password characters so as not to obtain the password characters input by the user, thereby improving the security of password input through the user.

Description

technical field [0001] The invention relates to the field of computer security, in particular to a method and device for inputting a password. Background technique [0002] With the development of the network, people often enter passwords online, especially passwords related to property such as account passwords and bank passwords, and the security of passwords is becoming more and more important. The more advanced the encoding technology for passwords, such as new digital certificates and bio-encryption technology, the more complicated it is to crack. People generally enter passwords through the physical keyboard provided by the network, but with the emergence of hackers, there are many Trojan horse programs similar to "keyloggers" that can easily steal the transaction passwords entered by users. Once the user's computer is infected with "keyloggers" "Trojan horse virus, the network system is planted with a "hook", and the hacker monitors and records the user's keystrokes ...
