SMS Registry Detects Parameter Manipulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Short Message Service (SMS) messages are vulnerable to manipulation of their parameters, such as sender addresses and message content, during transmission across different telephone networks, leading to fraudulent activities like spoofing and spam, which existing solutions fail to detect and prevent in real-time effectively.
Innovation Solution
A system comprising SMS registries communicably coupled to Short Message Service Centers (SMSCs) in both originating and terminating networks, which compare pre- and post-transmission message information to detect parameter manipulation, using encrypted out-of-band channels for communication and potentially involving firewalls to block manipulated messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If SMS messages are transmitted across different telephone networks, then message delivery capability is improved, but vulnerability to parameter manipulation increases
Solution Approach 1:
The patent applies preliminary action by capturing and storing SMS message parameters (such as sender address, message content, and timestamp) at the point of message creation or entry into the network before any potential manipulation can occur. This pre-captured data serves as a reference for later comparison to detect any alterations that may happen during transmission across networks.
Solution Approach 2:
The system implements feedback by continuously monitoring SMS message parameters at multiple points in the network and comparing them against the originally captured parameters. When discrepancies are detected, the system generates alerts and can automatically block suspicious messages, creating a closed-loop verification system that provides real-time feedback on message integrity.
2Measurement precision
If complex fraud detection procedures are implemented, then detection accuracy is improved, but real-time processing capability deteriorates
Solution Approach 1:
The patent applies partial action by focusing detection efforts on specific high-risk parameters such as sender address format validation, message content pattern matching, and transmission timing analysis. Rather than analyzing every aspect of each message in depth, the system selectively examines parameters most likely to indicate fraud, achieving effective detection with reduced processing overhead.
Solution Approach 2:
The system segments the fraud detection process into distinct stages: initial parameter capture, real-time validation rules checking, pattern matching against known fraud signatures, and detailed analysis only for suspicious messages. This segmentation allows the majority of messages to be processed quickly through automated rules while maintaining the option for deeper analysis when needed.
3Reliability
If existing fraud detection solutions are used, then some fraudulent activities are detected, but comprehensive real-time detection and prevention is not achieved
Solution Approach 1:
The patent implements a universal detection framework that can handle multiple types of SMS fraud (spoofing, phishing, spam, parameter manipulation) through a single integrated system. The same core architecture captures parameters, compares them against multiple verification criteria, and can apply different detection strategies depending on the suspected fraud type, eliminating the need for separate specialized systems for each fraud category.
Solution Approach 2:
The system introduces an intermediary verification layer between SMS message origination and delivery that acts as a mediator to validate message parameters. This intermediary component intercepts messages, performs verification against multiple criteria (parameter consistency, network routing validation, content analysis), and either approves or blocks messages before they are delivered, preventing fraud without requiring complex changes to existing network infrastructure.

AI summary
System and method for detecting SMS parameters manipulation. A first SMS registry is coupled to a first Short Message Service Center (SMSC) and optionally to other SMS registries. The first SMSC is within a terminating telephone network. The first SMS registry receives first and second information about an SMS message that was sent from another telephone network or from an External Short Messaging Entity (ESME) and is destined to the first SMSC. The first and second information represent status of the SMS message respectively before and after the SMS message enters the terminating telephone network. The first SMS registry or a firewall automatically compares at least corresponding portions of the first and second information. As a result of the comparison, in response to detecting a difference between the at least portions of the first and second information, the first SMS registry automatically sends a signal indicating SMS parameter manipulation.
