Mobile Messaging Attack Detection and Control System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies lack effective solutions to detect and mitigate 'text-bombing' attacks, where a large number of SMS messages are sent to a target device, causing harassment and incurring unnecessary fees, as they fail to efficiently monitor and limit message transmission and receipt based on volume and time proximity.
Innovation Solution
A messaging control method and system that detects incoming and outgoing messages, determines the number and time proximity of these messages, and limits message transmission and receipt by configuring the target device to block or throttle messages exceeding predetermined thresholds, sending notifications to users or supervisors for intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If message transmission and receipt are monitored and limited based on number and time proximity, then messaging attacks are prevented and harassment is reduced, but device complexity and processing requirements increase
Solution Approach 1:
The system segments message monitoring into distinct functional components: a detector module that identifies incoming and outgoing messages, a determiner module that calculates number and time proximity metrics, and a limiter module that enforces thresholds. This segmentation allows each component to perform its specific function efficiently, reducing overall system complexity while maintaining effective attack prevention
Solution Approach 2:
The system establishes predetermined thresholds for message number and time proximity before attacks occur. These thresholds are configured in advance and stored in the device, allowing the limiter to quickly compare incoming message patterns against pre-set criteria without requiring complex real-time analysis, thus reducing processing complexity while maintaining reliability
2Object-affected harmful factors
If all incoming and outgoing messages are monitored and limited, then text-bombing attacks are effectively prevented, but legitimate messaging functionality is restricted
Solution Approach 1:
The limiter applies message limiting selectively based on local conditions: it monitors specific message patterns, applies thresholds to particular time windows, and targets only messages that exceed the defined criteria. This localized application of limiting rules allows legitimate messaging to continue uninterrupted while precisely blocking attack patterns, thus preventing harm without unnecessarily restricting functionality
Solution Approach 2:
The system dynamically adjusts message limiting based on real-time message patterns and time proximity calculations. Rather than applying static blocking rules, the limiter continuously evaluates incoming messages against current patterns and thresholds, allowing flexible adaptation to different messaging scenarios while maintaining protection against attacks
Data Source
AI summary
A messaging control system and method are provided. The method includes detecting incoming messages to a mobile device and outgoing messages from the mobile device. One or more processors determine a number of and a time proximity of the incoming messages or the outgoing messages, and message transmission or message receipt by the mobile device is limited based at least on the number of and time proximity of the incoming messages or the outgoing messages.
