Instant Messaging Security Rules Engine for Confidential Chat Sessions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current instant messaging systems fail to adequately secure chat sessions containing confidential subject matter, as they can log and expose sensitive information to unauthorized parties or third parties, despite having built-in security features.
Innovation Solution
An instant messaging system equipped with a rules engine module that continuously monitors chat sessions for confidential content using predefined and user-defined rules, and an instant messaging module that secures chat sessions by saving transcripts to a secured directory, encrypting them, or preventing logging, thereby limiting exposure to third parties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If chat sessions are logged and stored for history purposes, then communication record-keeping capability is improved, but confidential information exposure risk increases
Solution Approach 1:
The patent applies local quality by differentiating the treatment of chat sessions based on their content sensitivity. Non-confidential chats are logged and stored for history, while confidential chats are automatically detected through keyword analysis and excluded from logging. This creates different storage qualities for different portions of the chat system, allowing history retention for ordinary conversations while protecting sensitive information.
2Reliability
If built-in security features are used to secure connections, then transmission security is improved, but protection against external access to chat logs remains insufficient
Solution Approach 1:
The patent implements preliminary action by proactively analyzing chat content during the conversation using keyword detection and pattern recognition. Before confidential information can be exposed through logging, the system pre-identifies sensitive chats and applies protective measures (exclusion from logs, encryption, or access restrictions). This preventive approach addresses the vulnerability before it can be exploited.
3Measurement precision
If user-defined rules are continuously added to improve detection accuracy, then confidential content identification is improved, but system complexity increases
Solution Approach 1:
The patent applies dynamics by making the rules engine adaptive and continuously updatable. Users can add, modify, or remove detection rules during system operation without requiring system reconfiguration or shutdown. The rules engine dynamically adjusts its detection parameters based on new user-defined criteria, allowing the system to evolve its detection capabilities while maintaining operational simplicity through automated rule management.

AI summary
An instant messaging system for securing chat sessions containing confidential subject matter during instant messaging from external entities, the system comprising: a rules engine module configured to continuously build and update a set of rules used to determine when a chat session between a first chat party and a second chat party during an instant messaging session contains confidential or uniquely classified subject matter by loading at least one default rules or previous session rules and enabling a user to provide user-defined rules until the instant message session is ended; and an instant messaging module configured to secure the contents in the chat session based on pre-defined user settings, the contents in the chat session being secured when the contents in the chat session is determined to contain confidential subject matter derived from the set of rules, the chat session is further secured by limiting the exposure of the contents in the chat session to third parties when the chat session is determined to contain confidential subject matter while enabling the first chat party and the second chat party to view the contents in the chat session.
