Embodiment Construction

[0018] The present invention will be further explained below.

[0019] A method for auditing TIM chat content includes the following steps:

[0020] a) Create a Windows window in the Windows system, and install a Windows message hook function through the SetWindowsHook function in the Windows system. The application can set up corresponding sub-processes to monitor the message delivery in the system and process them before these messages reach the target window program. The hook mechanism allows the application to intercept and process Window messages or specific events, and hang it into the system through system calls. Whenever a specific message is sent, the hook program captures the message before it reaches the destination window, that is, the hook function first gets the control right. At this time, the hook function can process (change) the message, or continue to deliver the message without processing, or it can force the end of the message delivery.

Abstract

A method for auditing TIM chat contents comprises the following steps: a) installing a windows message hook function; b) loading the DLL dynamic library of the windows system into a TIM application program through the windows message hook function; c) storing the real address as an original address; d) completing a hook operation of an export function of the message sending and receiving in the TIM program; e) the windows message hook function judging whether the sent message and the file contains secret-related key words set by a system administrator; f) the windows message hook function blocking a sent message or a file; g ) the windows system storing the message or the file sent by the TIM application program to a local sqlite database of the system. The message sending and receiving export functions of a TIM chat tool are obtained, and the chat information is analyzed and blocked, so that the audit on the chat information by the TIM software is improved, and secret divulging is prevented.
