Embodiment 1

[0049] An embodiment of the present invention provides a method for safely inputting a password based on a touch screen. Generally, there is a terminal processor on each smart terminal, which is used to process instruction signals or other information input by the user. In the embodiment of the present invention, a security processor is also included. When the user needs to input a password, the security processor to process.

[0050] Such as figure 1 As shown, the touch screen-based secure password input method provided by the embodiment of the present invention includes steps S110-S150, specifically as follows:

[0051] S110: Receive a password input request transmitted by the terminal processor.

[0052] When the user uses Alipay, WeChat and mobile banking to pay on the smart terminal, or swipes the bank card, or logs in to the application program on the smart terminal, he needs to enter the password on the smart terminal, and the touch screen module will transmit the pas...

Embodiment 2

[0085] An embodiment of the present invention provides a password security input device based on a touch screen. Such as image 3 As shown, the device may include a terminal processor 310 , an analog security switch 320 , a touch screen module 330 and a security processor 340 .

[0086] The security processor 340 is configured to receive the password input request transmitted by the terminal processor 310; send the first control signal to the analog security switch 320 according to the password input request; and analyze the password input by the user according to the button coordinate information input by the user information; encrypting the parsed password information to obtain encrypted ciphertext; sending the above ciphertext to the terminal processor 310 for authentication of the password information;

[0087] The analog security switch 320 is used to establish a data channel between the security processor 340 and the touch screen module 330 according to the first contro...

Abstract

The invention provides a touch screen based password security input method and apparatus. The method comprises: receiving a password input request transmitted by a terminal processor; according to the password input request, sending a first control signal to an analog safety switch to establish a data channel between a security processor and a touch screen module; according to key coordinate information input by a user, analyzing password information input by the user; encrypting the analyzed password information to obtain an encrypted ciphertext; and sending the ciphertext to the terminal processor to authenticate the password information. The apparatus comprises the terminal processor, the analog safety switch, the touch screen module and the security processor. According to the touch screen based password security input method and apparatus provided by the invention, the security of inputting the user password information is improved.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method and device for securely inputting passwords based on a touch screen. Background technique [0002] With the popularization of touch screen technology on smart terminal devices, when people use Alipay, WeChat and other payment methods to pay, or need to enter a password when swiping a bank card, they can enter the password on the virtual keyboard displayed on the smart terminal to pay. [0003] Most of the existing ways of using the virtual keyboard on the smart terminal to input passwords are that the touch screen on the smart terminal directly transmits the key coordinate information when the user enters the password to the processor on the smart terminal, and the processor transmits the key coordinate information when the user enters the password. The button coordinate information is converted into corresponding password information. [0004] However, in ...
