Embodiment 1

[0054] In schools or meeting places, when using display devices for teaching, users generally need to log in to the network or account, and enter the password through the following methods.

[0055] Step 1: When the password input page pops up, a virtual keyboard pops up on the screen at the same time. There is a password input function key on the virtual keyboard. Click this button, and the display device sends a password input http request message to the server, including the display device identification code , network or account name, password input service request generation time;

[0056] According to the password input service request received from the display device, the server generates and saves the unique identification code of the password input service request. The identification code includes, for example, the display device identification code abcd for sending the password input service request, and the server The url address www.passwordinput.com / abcdxxx assign...

Embodiment 2

[0062] According to Embodiment 1, when multiple different password input service requests are not considered, it can be further simplified, namely:

[0063] Step 1: When the password input page pops up, a virtual keyboard pops up on the screen at the same time. There is a password input function key on the virtual keyboard. Click this button, and the display device sends a password input service request to the server without including the display device identification code. , network or account name, password input service request generation time;

[0064] According to the password input service request received from the display device, the server generates and saves a unique identification code for the password input service request, and the identification code only includes the url address www.passwordinput allocated by the server for this password input service request .com / xxx, the server sends the identification code to the display device;

[0065] Step 2: The display de...

Abstract

The invention relates to a password safe input method for a display device. The method is characterized by comprising the following steps: the display device sends a password input service request to a server, receives an identity code generated according to the password input service request from the server, generates and displays a two-dimensional code according to the information in the identity code for the scanning of an electronic device, so that the password can be input in a corresponding page in an address distributed for this password input service request at the server through the electronic device, the password input by the electronic device in the server is acquired and then input in a shielding manner. The invention further provides a display device and system for realizing password safe input. Through the adoption of the password safe input method disclosed by the invention, a user can input the password through an additional portable electronic device when performing the screen presentation, other people cannot directly acquire the password through a display screen, and the security of the user password is guaranteed.

Description

technical field [0001] The invention relates to password security input technology, in particular to a password security input method for a display device and its equipment and system. Background technique [0002] With the development of modern information technology, information security and confidentiality have become the focus of people's attention. For example, it has become more and more important in e-commerce, online banking, and digital signatures, and more technical investment is being tried. [0003] With the rapid development of password technology itself, there are many hidden dangers in the password input process. For example, criminals installed cameras on the password input mechanical keyboard of bank ATMs without permission to obtain user account numbers and passwords, which brought losses to users. In another application scenario, when the user uses a large-size touch screen for operation or demonstration, he needs to enter a password according to the requi...
