Method and device for enhancing user information input security

Abstract

The invention discloses a method and device for enhancing user information input security. The method comprises steps as follows: a timer triggers an input widget to generate interference information at definite time, and the input widget transmits the interference information to a message transfer chain; and when receiving the information on the message transfer chain, the input widget judges whether the received information contains interference information according to an interference time list or preset identifier value, if so, discards the received information, and else, saves the received information and transmits false information to the widget interface. After the generated interference information is interpolated into the message transfer chain, even if a hacker hook intercepts information on the transfer chain, the information is mixed information and can not endanger the user privacy, thereby enhancing the user information input security.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method and device for improving the security of user information input. Background technique [0002] With the development of network technology, e-commerce is developing at an astonishing speed. At the same time, the security of the network is being challenged day by day due to the attacks of hackers, the proliferation of viruses and Trojan horse programs. Email bombs, glacier Trojan horses, code red, shock wave virus, worm virus, Sasser, etc., virus samples are constantly changing and refurbished, and their performance characteristics are also strange. Traffic increases network bandwidth, congests the network and paralyzes it, or steals other people's privacy. 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 p...

Problems solved by technology

Email bombs, glacier Trojan horses, code red, shock wave virus, worm virus, Sasser, etc., virus samples are constantly changing and refurbished, and their performance characteristics are also strange. Traffic increases network bandwidth, congests the network and paralyzes it, or steals other people's privacy

In particular, the currently popular Internet thief Miracle variant, as well as 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 relatively large losses to poisoned users.

[0003] From the principle of Windows message transmission, the keyboard information (key value and scan code) is first intercepted by the system through the keyboard interrupt program as plain text, and then transmitted to the corresponding application interface or focus window according to the message transmission chain. The running program can intercept the button information through hooks (Hook), etc., and the Trojan horse virus steals important information, such as user account numbers and passwords, by intercepting the button information.
