Instant Messaging Identity Verification System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing instant messaging systems lack the ability to verify the identity of participants during a session, making them vulnerable to unauthorized access and potential security threats such as disclosure of confidential information and phishing.
Innovation Solution
A method and system that allows participants to verify the identity of others through configurable authentication challenges during an instant messaging session, with the results displayed in real-time and logged for session history, using an authentication server to validate credentials and manage session integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication is only performed at sign-on using LDAP directory integration, then the authentication process is simple and quick, but the system cannot verify identity during ongoing sessions, leaving it vulnerable to unauthorized access
Solution Approach 1:
The system performs preliminary authentication at sign-on through LDAP directory integration, establishing initial identity verification. This preliminary action allows the system to have a baseline authentication mechanism in place before sessions begin, resolving the contradiction by providing both initial security and a foundation for ongoing verification capabilities.
Solution Approach 2:
The authentication system transitions from static sign-on verification to dynamic ongoing session verification. The system can now perform authentication challenges during active sessions, allowing identity verification to adapt to different session states and security requirements, thus resolving the contradiction between simplicity and reliability.
2Object-affected harmful factors
If no ongoing authentication verification is performed during sessions, then the communication flow is uninterrupted and simple, but confidential information may be disclosed to unauthorized users
Solution Approach 1:
The system applies preliminary anti-action by implementing authentication challenges during sessions before confidential information is exchanged. This preventive measure stops potential unauthorized access before harm can occur, resolving the contradiction by prioritizing security prevention while maintaining session continuity for authenticated users.
Solution Approach 2:
The system implements feedback mechanisms where authentication status is continuously monitored and verified during sessions. This feedback loop allows the system to detect and respond to potential unauthorized access attempts in real-time, resolving the contradiction between security and ease of operation by providing continuous verification without disrupting legitimate communication.
3Reliability
If authentication challenges are implemented during sessions, then identity verification reliability improves, but the session may be interrupted and user experience degraded
Solution Approach 1:
The system implements periodic authentication challenges at strategically chosen intervals during sessions, such as before sharing confidential information or at scheduled checkpoints. This periodic approach maintains security verification while minimizing interruptions to the overall session flow, resolving the contradiction between reliability and time loss.
Solution Approach 2:
The system changes authentication parameters dynamically based on session context, such as adjusting the frequency and type of challenges based on the sensitivity of information being exchanged. This allows the system to maintain high reliability when needed while reducing interruptions during routine communication, resolving the contradiction between verification reliability and session continuity.

AI summary
A system for verifying the identity of a chat partner during an instant messaging session. The identity of an instant messaging partner can be verified at any given moment during an instant messaging session. The status of the verification is displayed in the current session, and is contained into any subsequently saved session history file. Prior to the beginning of communication, a participant has the ability to challenge one or more other participants to verify that they are really the people assigned to the corresponding instant messaging identifiers. During the instant messaging session, participants are further allowed to challenge any other participant before going further with the session (e.g. prior to discussing confidential information or accepting files). The system addresses the problem of an unauthorized user gaining access to another user's instant messaging identifier.
