no. 1 example

[0036] see figure 1 , propose the first embodiment of the password input method based on the touch screen of the present invention, the password input method includes the following steps:

[0037] Step S101: The user enters the password through the touch screen

[0038] The password input described in step S101 mainly means that in the scenarios of electronic payment and server login, the touch terminal needs to send the password input by the user to the remote host computer system, and the host computer system will perform the password verification on the password. Verification situation. The password of the present invention should be understood in a broad sense, including all private information that can be used as identity verification for input.

[0039] Step S102: the central processing unit hands over the control of the data bus to the cryptographic controller

[0040] When the user performs ordinary operations on the touch screen except for password input, the centr...

[0049] see figure 2 , propose the second embodiment of the password input method based on the touch screen of the present invention, the password input method includes the following steps:

[0050] Step S201: The central processing unit randomly arranges password input characters on the touch screen for users to input passwords through the touch screen

[0051]The character arrangement in this embodiment is not solidified, but the central processor controls the touch screen to display randomly arranged password input characters, thereby preventing the solidified character arrangement information from being stolen and further improving the security of password input.

[0052] Step S202: The central processing unit hands over the control of the data bus to the cryptographic controller, and sends the character arrangement information to the cryptographic controller

[0053] When the user needs to input a password through the touch screen, the central processing unit releases th...

Abstract

The invention discloses a password input method based on a touch screen, and a touch terminal. The password input method includes the steps of firstly, obtaining touch information of the touch screen through a password controller when a user inputs a password through the touch screen; secondly, obtaining password information through the password controller according to the touch information; thirdly, sending the password information to an upper computer system through the password controller. According to the password input method based on the touch screen, by adding the password controller which is completely independent of a central processing unit, the password is inputted and transmitted through the special password controller, interference and processing which are conducted on the password information through the central processing unit are completely avoided, the password information is prevented from being obtained by a fake program through the central processing unit and a memorizer, the risk that the password is revealed is eliminated, and security of the password inputted through the touch screen is improved. Meanwhile, the universal touch screen can be used in the method instead of a special touch screen, and therefore implementation cost is low, and the industrial advantages are achieved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a password input method based on a touch screen and a touch terminal. Background technique [0002] PIN pad is an identity verification input device widely used in electronic payment. It is used in transaction occasions such as banks, securities, stores, online shopping and mobile payment. Ensuring the security of input password is the basic function that PIN pad must have. With the development of touch screen technology, many terminal devices are equipped with touch screens, so that a soft keyboard (or virtual keyboard) can be displayed on the touch screen for users to input passwords through the touch screen. [0003] The touch terminal in the prior art generally controls the touch screen to display the soft keyboard through the central processing unit (CPU), and the touch screen transmits the position information of clicking the soft keyboard to the central processor, a...
