Sender Messaging Service Feedback Loop for Spam Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unwanted electronic messages, such as spam and phishing, burden recipients and messaging service providers, leading to increased storage costs and resource demands, as well as reputational issues for senders, due to the inability to effectively identify and filter out abusive messaging.
Innovation Solution
Implementing a system where sender messaging services identify potential message abuse by analyzing various indicators, including undeliverable messages, recipient feedback, message content, and sender behavior, and notify recipient messaging services to suspend abusive accounts and warn against identified abuse, thereby filtering out abusive messages and maintaining a high-quality messaging reputation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If messaging service providers increase messaging resources to handle all incoming messages, then message delivery capability is improved, but service cost increases
Solution Approach 1:
The system performs preliminary filtering of abusive messages at the sender's messaging service before messages reach recipient services. By analyzing feedback loops and identifying abusive senders in advance, the system prevents abusive messages from consuming recipient resources, thereby reducing the need for expensive infrastructure upgrades while maintaining legitimate message delivery capability.
Solution Approach 2:
The invention extracts and removes abusive messages from the messaging flow by identifying them through feedback loop analysis and content inspection. Abusive messages are separated from legitimate messages at the sender's service, preventing them from burdening recipient messaging infrastructure and reducing the resources needed for message handling.
2Reliability
If messaging service providers implement feedback loops to identify abuse, then message quality is improved, but system complexity increases
Solution Approach 1:
The system implements feedback loops where recipient messaging services report abuse information back to sender services. This feedback mechanism enables senders to identify and stop abusive messaging behavior, improving message quality. The feedback is processed through standardized protocols that manage complexity while maintaining effectiveness.
Solution Approach 2:
The invention uses intermediary processing at the sender's messaging service to analyze feedback information and determine abuse. Rather than requiring complex real-time coordination between all messaging services, the system uses intermediary feedback reports and pre-computed sender profiles to simplify the abuse identification process while maintaining high message quality.
3Measurement precision
If sender messaging services analyze multiple indicators to identify abuse, then detection accuracy is improved, but processing time increases
Solution Approach 1:
The system performs preliminary analysis of sender behavior and message patterns before actual message delivery. By pre-computing sender profiles, analyzing feedback loop history, and identifying abusive patterns in advance, the system achieves high detection accuracy without requiring lengthy real-time analysis during message transmission, thus reducing processing delays.
Solution Approach 2:
The invention segments the abuse detection process into separate analytical components: feedback loop analysis, content inspection, sender behavior patterns, and recipient engagement metrics. Each component processes specific indicators independently and contributes to the overall detection decision, enabling comprehensive analysis with optimized processing time through parallel evaluation of multiple indicators.
Data Source
AI summary
A request to send messages is received by a sender messaging service from a sender. The messages are for one or more recipients associated with one or more recipient messaging services. The sender messaging service can determine that at least one of the plurality of messages is indicative of message abuse. The sender messaging service can generate a warning message which includes at least one of an indication of the sender, an indication of an address of the sender, and an indication of the message abuse. The sender messaging service can send the warning message to the one or more recipient messaging services.
