Abstract

The invention discloses an IM communication system and a communication method thereof. The system comprises a server, configured to acquire user information of various types of IMs used by users fromvarious IM servers, and associate and store the acquired user information; and an IM terminal, configured to acquire the user information of the user to be communicated from the servers, configure a corresponding security level for the IM communication system according to the security level selected by the user, and perform communication between a transmitting end and a receiving end based on theconfigured IM communication system, wherein the transmitting end serves as the IM terminal of a sender, and the receiving end serves as an IM terminal of a receiver. The security level of the IM communication system provided by the invention can be extended as required, so that the identity information and privacy of the user can be better protected.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an instant messaging (IM) system and a communication method thereof. Background technique [0002] At present, common IM software such as QQ, WeChat, etc., do not pay enough attention to user privacy issues. Its main manifestations are as follows: first, these IM software and protocols have no difference in the security mechanisms set for all users, and do not consider the different levels of security requirements of different users, ignoring the privacy needs of users with high security levels; second, some IM software IM software and protocols only consider the security of user communication content, but do not consider the security of end user identity information, and encrypted information is often more sensitive and more likely to attract attention; third, these IM software and protocols adopt a client-server architecture model, which means This model is cent...
