Embodiment 1

[0048] This embodiment provides a method for improving input security, and takes the input performed by the user through a physical keyboard (such as a USB keyboard or PS2 keyboard) as an example to describe in detail, as shown in figure 1 shown, including:

[0049] Step 101: The security input plug-in receives a reminder message of cursor appearance, links to the NT driver, and sends a keyboard filtering request to the NT driver;

[0050]Specifically, when the security input plug-in links to the NT driver, the NT driver creates a keyboard driver device object for each keyboard device according to the current keyboard device. When the user generates keyboard input through the keyboard device, the corresponding keyboard driver device object will automatically receive information and respond to it.

[0051] In the Windows system, when the NT driver is loaded, it runs the NT driver device. For the keyboard device, it needs to add the corresponding function driver under the NT dr...

Embodiment 2

[0200] This embodiment provides a device for improving input security, such as Figure 5 As shown, including: keyboard filter driver 1, security input plug-in 2 and NT driver 3; among them,

[0201] The keyboard filter driver 1 includes a first receiving module 101, a judging module 102, an operating module 103, a clearing module 104 and a storage module 105;

[0202] The first receiving module 101 is configured to receive keyboard input information;

[0203] The judging module 102 is used to judge whether the keyboard input information is an analog keyboard input information, if so, trigger the clearing module 104 to work, otherwise trigger the operation module 103 to work;

[0204] The operation module 103 is used to generate a keyboard input information, store the keyboard input information received by the first receiving module 101 together with the generated keyboard input information into the end address of the NT driver password storage queue, and generate the generate...

Abstract

The invention discloses a method and a device for improving input safety, and relates to the field of information safety. The device comprises a keyboard filtering driver, an NT driver and a safety input plug. The method comprises: the keyboard filtering driver filters simulation keyboard input information and stores real keyboard input information in the NT driver; and the safety input plug sends a verification code to the NT driver for verification, and acquires password data from a result returned from the NT driver after the verification is successful. The method and the device provided by the invention can effectively protect data such as passwords which are input by a user from a keyboard, and have the characteristics of being safe and convenient.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method and device for improving input security. Background technique [0002] With the development of network technology, e-commerce is developing at an astonishing speed. At the same time, the attacks of hackers, the proliferation of viruses and Trojan horse programs make the security of the network increasingly challenged. In particular, the currently popular internet thief Miracle variant, and Trojan horse programs such as KeyLogger, use the means of recording keystroke information to steal bank passwords and illegally obtain other people's funds, causing great losses to users. In the prior art, under the Windows system, the NT driver is used to create a keyboard driver device object for the keyboard device, and provide the required driver distribution processing function for the created keyboard driver device object, and can respond to the request of the safe input plug-...
