A security tag-based instant messaging system and method

Abstract

The present invention relates to an instant communication system and method based on a security label, in which an available security label is obtained for message data and a chat room in an instant communication client application; and the message data with the security label is processed in the instant communication client application; Display chat rooms with security labels; obtain address book resources with security labels for users of instant messaging client applications in the instant messaging server; forward instant messages according to security labels; obtain users and chat rooms for instant messaging client applications A list of available security labels; generate available security labels for instant messages and chat rooms in the instant messaging management server; create and edit security labels required by the instant messaging system, and generate available security labels according to users in the instant messaging client application Address book; a security label is a digital entity bound to message data, address book, and chat room in the instant messaging system.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an instant messaging system and method based on a security label. Background technique [0002] The instant messaging system can not only realize the sending of instant messages such as text, pictures, emoticons, etc., but also transmit media information, which greatly improves the communication efficiency between people and has been widely used. However, the instant messaging system puts more emphasis on convenience and does not fully consider security, which leads to problems such as uncontrolled information dissemination and personal information leakage. At present, there are already some solutions focusing on solving this problem. CN201611190178.2 proposes an instant messaging sending method, a control method, a sending end, and a receiving end. This patent adds an extension item to the instant message sent by the sending end, and the receiving end can The contr...
