Telephone Message Termination Monitoring via Fuzzy Pattern Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transmission of SMS or MMS messages, especially those containing confidential data, is vulnerable to unauthorized termination by third-party entities, compromising security and confidentiality, as existing methods are not applicable due to the message's confidentiality and specific characteristics.
Innovation Solution
A method that detects a previously stored pattern within the message using fuzzy logic techniques to identify the trigger and verify the termination mode by comparing the sender and routing identifiers, allowing for the detection of unauthorized routing bypasses without altering the message content or requiring verification codes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a verification code is added to the message content to detect unauthorized termination, then the security can be improved, but the message confidentiality is compromised and the device complexity increases
Solution Approach 1:
The verification mechanism is segmented into two independent parts: a pattern embedded in the message content (which remains confidential) and a separate verification code generated by the monitoring system using the pattern and message characteristics. This segmentation allows verification without exposing the original message content.
Solution Approach 2:
A monitoring system acts as an intermediary between the message transmission and verification processes. It receives message metadata (sender ID, routing equipment ID, timestamp), generates a verification code based on these characteristics, and compares it with the received verification code without needing to access or expose the confidential message content.
2Reliability
If the message content is accessed to add verification codes, then the security can be improved, but the ease of operation deteriorates and device complexity increases
Solution Approach 1:
The verification mechanism extracts essential characteristics from the message (sender ID, routing equipment ID, timestamp, pattern position) without accessing the confidential message content. These extracted characteristics are sufficient to generate and verify security codes, maintaining operational simplicity while ensuring security.
3Measurement precision
If a test robot is used to send test messages for verification, then the detection capability can be improved, but the adaptability to real confidential messages deteriorates
Solution Approach 1:
The monitoring system performs self-verification by automatically generating verification codes based on message characteristics and comparing them with received codes. This eliminates the need for external test robots and enables the system to verify any message type (SMS, MMS, email) without requiring message-specific test infrastructure.
4Reliability
If the pattern changes for each message to enhance security, then the security is improved, but the difficulty of detecting and measuring increases
Solution Approach 1:
The pattern is predetermined and embedded in the message template before the message is sent. The monitoring system has this pattern stored in advance, allowing it to easily detect and verify the pattern's presence and position in the received message without complex real-time analysis, thus maintaining both security and detection simplicity.

AI summary
- The invention relates to a method (100) for monitoring the mode of termination of a telephone message comprising a phase (102) of sending a telephone message on behalf of a triggerer to at least one target number. The method (100) further comprises an analyzing phase (110) comprising the following steps: - detecting (112), in said message, a pattern stored in memory beforehand, using a fuzzy-logic detecting method; - identifying (114), from said pattern, the triggerer of said message; - determining (116) a reception-end sender identifier and/or an identifier of an item of routing equipment of said message, by analysing said message; and - verifying (118) a mode of termination of said message depending on at least one of said identifiers and on said triggerer. - Non-synchronized communications sent to mobile telephone numbers, and methods for monitoring the mode of termination of such communications.
