Sender Verification Service for Spoofing Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sender spoofing detection techniques often fail to differentiate between legitimate and illegitimate activities, leading to false positives and undetected fraudulent activities, as they may block legitimate communications that differ from the actual source and allow malicious activities from compromised accounts to go undetected.
Innovation Solution
A verification service that sends a verification message to the sender device to confirm the authenticity of the data source, allowing the server computer to block or deliver data based on the sender's response, thereby ensuring accurate sender verification and preventing fraudulent activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sender spoofing detection techniques block communications that differ from the actual source, then fraudulent activities are prevented, but legitimate communications are falsely blocked
Solution Approach 1:
The system performs preliminary verification by sending a verification message to the sender device before blocking the communication. This advance check allows the system to confirm whether the sender device actually sent the data, preventing false positives while maintaining fraud detection. The verification message is sent through a different communication channel to ensure reliable delivery and response.
Solution Approach 2:
The system implements a feedback mechanism where the sender device receives a verification message and responds to confirm whether it sent the data. This feedback loop allows the server to make informed decisions about blocking or delivering communications based on actual sender confirmation, rather than relying solely on header analysis which can be spoofed.
2Ease of operation
If sender spoofing detection techniques allow communications from any source, then legitimate communications are delivered, but fraudulent activities go undetected
Solution Approach 1:
The system introduces an intermediary verification process between the sender and recipient. Instead of directly trusting the sender's claimed identity or blindly allowing all communications, the system acts as a mediator by sending verification messages to the sender device and using the response to determine whether to deliver the communication. This intermediary step enhances both delivery reliability and fraud detection.
3Device complexity
If verification messages are sent through the same communication channel as data, then verification process is simplified, but verification messages may be blocked by malicious filters
Solution Approach 1:
The system transitions the verification message transmission to a different dimension or channel than the original data communication. By sending verification messages through a separate communication channel, the system ensures that verification traffic cannot be blocked by filters targeting the original communication channel, while still maintaining the ability to verify sender identity effectively.
Data Source
AI summary
Concepts and technologies are disclosed herein for verifying sender information. According to various embodiments of the concepts and technologies disclosed herein, a verification service can determine, receive a request, or receive a call to verify sender information associated with data. The server computer generates and delivers a verification message to a sender device in response to determining that sender information verification is to be provided. The server computer receives a response indicating if the data was sent by the sender device. If the response indicates that the sender device did not send the data, the server computer can block delivery of the data, generate alarms or alerts, take other actions, and/or take no action. If the response indicates that the sender device sent the data, the server computer can deliver the data, provide a verification response to the recipient device, take no action, and/or take other actions.
