Device and method for preventing account passwords from being tampered

Abstract

An embodiment of the invention discloses a method for preventing account passwords from being tampered. The method includes: monitoring whether files in a system kernel layer are in operation or not by the aid of a function hook mounted in the system kernel layer; if files in the system kernel layer are in operation, judging whether the files are behavior files altering the account passwords according to parameter information of file calling interfaces; if the files are behavior files altering the account passwords, popping up a prompt message to prompt a user whether to allow the files to operate or not; if the user chooses to allow the files to operate, allowing the files to continue operating, and otherwise, stopping the files from operating. The embodiment of the invention further discloses a device for preventing the account passwords from being tampered. The method and the device for preventing the account passwords from being tampered have the advantages of simplicity in operation, high applicability, improvement of file recognition efficiency and reinforcement in safety of system account passwords.

Description

Technical field [0001] The present invention relates to the field of electronic technology, in particular to a method and device for preventing account passwords from being tampered with. Background technique [0002] With the increasing popularity of computers and mobile phones, people's study, work, and life are increasingly inseparable from computers and mobile phones. People increasingly rely on computers (or mobile phones) to make more and more personal information on computers, and computer security is also particularly important. However, the primary issue of computer security is account security, because the account determines the right to use this computer. For this reason, maintaining the security of computer accounts has become the primary problem to be solved in maintaining computer security, and how to maintain the security of account passwords has become an urgent problem to be solved. [0003] The solution to account password security in the prior art is to extract...

AI Technical Summary

Problems solved by technology

The above-mentioned account password protection process takes a long time and has low accuracy

In addition, in the prior art, feature extraction is only performed on existing files in the system. When a new file is added to the system and the file has the behavior of tampering with the account password, the system cannot detect the above file through feature matching, and thus cannot The operation of the above files is blocked to protect the security of account passwords, which has low applicability and security loopholes
