Email Source Verification via Authorization Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high volume of unsolicited electronic messages, commonly known as spam, poses challenges in resource management and communication bandwidth, as traditional methods to identify and block spam sources are easily circumvented by spammers using misleading source identifications, making it difficult to accurately track and assign accountability for these unwanted messages.
Innovation Solution
A method and system that verifies the source of unsolicited electronic messages by requesting authorization with a unique bit string, which is included in the message header, allowing for tracking and identification of the message source, thereby assigning accountability and facilitating the detection of forged or cloaked source identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional e-mail applications use simple source address blocking, then implementation is easy, but spam initiators can easily circumvent by using misleading source identifications
Solution Approach 1:
The system performs preliminary authorization by sending a request to the source address before the e-mail is transmitted. The source must respond with an authorization indicator that is then embedded in the e-mail header. This preliminary action ensures that only authorized sources can send messages, preventing spammers from using fake addresses without being blocked.
Solution Approach 2:
The system implements a feedback mechanism where the receiving system sends an authorization request to the source address, and the source must provide a unique authorization indicator in response. This feedback loop verifies the authenticity of the source address before allowing message transmission, making it difficult for spammers to circumvent blocking.
2Reliability
If the system processes and stores all incoming e-mail messages by default, then no messages are lost, but significant time and resources are consumed when manually processing large volumes
Solution Approach 1:
The system performs preliminary filtering by checking for the presence of a valid authorization indicator in the e-mail header before messages are stored or processed. Messages without proper authorization can be identified and handled differently (e.g., automatically deleted or quarantined), reducing the manual processing burden while ensuring authorized messages are preserved.
3Adaptability or versatility
If the system allows high bandwidth for unsolicited messages, then communication freedom is maintained, but valuable communication resources are occupied and important messages are delayed
Solution Approach 1:
The system uses feedback control by monitoring the authorization responses from source addresses. Once a source is authorized and the authorization indicator is validated, the system can implement rate limiting or bandwidth management for that specific authorized source, ensuring that communication freedom is maintained for legitimate users while preventing spam sources from consuming excessive resources.

AI summary
An unsolicited electronic message source verification and tracking method and system for providing an efficient and convenient mechanism for tracking identification of unsolicited electronic message (e.g., e-mails) sources is presented. In one embodiment, a request for authorization to forward an electronic message is received. The request for authorization includes a request source address. A response is sent including an authorization indicator (e.g., a unique bit string) is sent to the request source address. An electronic message is received and a determination is made if the electronic message includes a valid authorization indictor. If the electronic message does include a valid authorization indicator the electronic message is associated with the request source address and the association is tracked. In one exemplary implementation, a source address included in the electronic message is compared to the request source address and discrepancies are noted.
